THE SINISTER INVASION

By Alexander Blade

Birrel rebelled at the idea of becoming a
cosmic counter-spy. But he was the one Earthman
whom a quirk of nature had fitted for the job....

It was strange, how easy it was to step right out of your own life, right out of the familiar Earth into cosmic mystery! As easy, Birrel was to think later, as opening a door....

As Birrel walked into his 71st Street apartment, snapping on the light and pocketing his keys, he suddenly stopped, tense with surprise.

A man he had never seen before stood facing him. A commonplace-looking man with a gray hat, gray suit, and a grayish, young-middle-aged face. His voice was mild as he said,

"Ross Birrel?"

"That's right," said Birrel. Then anger swept away his astonishment. "Who are you and how the hell did you get in here?"

"We'll discuss that later," said the gray man. "Right now, I want you to come with me. Official business."

"What kind of official business?"

"We'll discuss that later too."

Birrel started forward, his temper dangerously high. Then he stopped. The gray man's hand was in his coat pocket, and it was gripping something in that pocket. He said,

"Please don't be difficult, Mr. Birrel."

Birrel said, "If you're an official of some sort, let's see your credentials."

"I'm afraid," said the other, "I don't have any."

"I thought so." Birrel began to breathe hard. "Listen, you've made a mistake. I'm not a rich man, or a rival gangster, or anybody you want. I'm an electrical engineer, a bachelor, and I'm stone broke."

"We know that," murmured the gray man. "Now will you come along?"

Birrel suddenly decided that the man was crazy. New York was full of nuts these days, people flipping their lids and doing daffy things. This was one of them—and there was only one thing to do.

"All right, but you'll regret this," he said. He started to turn his back on the gray man. "When you find out you're wrong—"

Birrel, turning, whirled with sudden speed, his arm snaking out to catch the gray man's neck with the edge of his hand, the old trick they'd taught him in the OSS in war-time.

It didn't work.

The gray man ducked and chopped expertly with his left hand. A numbing pain hit Birrel's extended arm.

For the first time, the gray man smiled. "Sorry. But I was in the OSS too, you see."

Birrel, holding his aching arm, stared. This wasn't a nut after all. But what—?

"Look, Mr. Birrel. I have no sinister designs against you, in any way. We merely have a proposition to put to you. You can accept or refuse it. But unfortunately, I have to do this secretly. That's why I couldn't phone or write or approach you in public."

Birrel thought rapidly. Not a nut, no. But what kind of official business would have to be done this secretly? He didn't like it, not at all.

"Shall we go?"

Birrel looked at the hand in the coat pocket. He went.

He came out into the cool dark wetness of 71st Street, the summer shower over and the red and white neon signs toward Broadway reflected cheerily on wet asphalt. A sedan, with a man at its wheel, was waiting.

He heard the mild voice close behind his ear. "Get right in, Mr. Birrel."

The car swept them up the West Side Highway, with the electric glow of Manhattan behind them. Ahead, the strung-out lights of George Washington Bridge arched the black gulf of the river.

Birrel sat in the back seat, with the gray man keeping well away from him at the other end of the seat. He could see nothing of the driver but a thick neck under a crusher hat.

They crossed the Hudson and went on westward, skirting cities and running quietly and fast through a region of small factories and junk-heaps and power-plants.

Birrel felt a mounting panic. What the devil had he got mixed up in? He tried to think why anyone would want to grab him like this.

He couldn't think of anything. Since the war he'd completed his education, taken his engineering degree, landed a job in a Long Island electric company, and—that was all. He didn't know any technical secrets, he wasn't doing any top-secret work, he was an utterly undistinguished thirty-year-old engineer and nothing more.

Then why?

"Listen," he said, "I know there's a mistake—"

"No mistake," said the gray man. He added, "We're nearly there."

"There" was a high wire fence with a locked gate and a red sign, INDUSTRIAL CYANOGEN COMPANY—DANGER, KEEP OUT. A man came out of a little wooden building inside the gate, and unlocked and opened it. The car went on through.

It stopped, after a moment, in front of a big, dark old-fashioned brick factory building with a forlorn, out-of-date look about it. The only light was a dingy bulb over the door in front.

"This is it, Birrel. Come along."

Inside, Birrel got a shock of surprise. It wasn't the cavernous, dark interior he expected. There was light, the sound of clicking typewriters and teletypes, the clack of heels on corridor floors.

The old factory building, he saw now was a blind. Behind its dingy walls and masked windows were at least two floors of offices. The doors of them all were closed, but he heard the hum and buzz of earnest activity from behind them.

Gray-face nudged him toward one of the doors. The thick-necked driver went on somewhere.

Birrel looked around a featureless little office with a battered table, some office chairs, and nothing else.

He turned. "What the devil is this place?"

"A government agency," said Gray-face.

Birrel said, "Listen, how long are you going to keep this—"

He stopped, and was aware that his jaw was hanging in foolish surprise. A man had come into the office.

A stocky, iron-haired man of fifty or more, with a heavy, seamed face and eyes not much softer than flint. Birrel had never seen him face to face before, but he knew him.

"Why—"

"Yes," said Gray-face, obviously enjoying himself. "It's Mr. John Connor." He turned and said, "Here he is, Mr. Connor. I believe he thought we were taking him for a ride."

"All right, Paley," said Connor brusquely. "Sit down. Birrel. Sorry to haul you out here but this is important. Will you take that moronic stare off your face and sit down?"

Birrel sat, swallowing hard. This he hadn't expected.

He had been in the OSS more than a year, and he'd never even got within shouting distance of John Connor, the most famous of its directing brains. And now, eleven years later, to meet him this way in a masked factory that was an office—

Birrel said, weakly, "Then this is a government agency?"

"It is," said Connor. "The most secret one of all. We don't give out interviews, and have addresses, like the CIA and FBI." He nodded toward the gray-faced man. "You'll understand why I sent Paley for you this way, why I couldn't write or phone you."

"But I thought you'd retired, after the war!" Birrel said. "The newspapers—"

John Connor said disgustedly, "The hell and all of an OSS man you must have been, if you believe everything you read in newspapers."

Birrel thought he understood now. One of the secret counter-espionage agencies by which America defended itself—so secret that probably few government-officials even knew about it. But—

Connor's rough voice answered his thought. "We need a man, Birrel. For a job. And it must be a man we can trust absolutely. That's why we looked through the OSS files—and found you."

"Oh, now, listen," protested Birrel, rising. "My service was years ago, I've got a profession, and this isn't war-time now. You can find better agents than me—"

Connor said brutally, "I could find five hundred agents better than you. I'd rather have anyone of them than you. Unfortunately, you've got something they haven't."

"What?"

"The right face, Birrel."

Birrel didn't get it, he didn't get it at all. But Connor gave him no time to think. He demanded,

"You'd help us if you thought it might mean life or death to your country, wouldn't you?"

Birrel knew he was about to be trapped, but there was only one way you could answer that. "Sure, but—"

Connor cut him off. "Fine. Now I'm going to show you someone, Birrel. Come along."

They went out of the office, and down a long corridor and then down a flight of concrete steps. Connor said nothing on the way, and neither did Paley.

The cement-walled basement corridor below was chilly. Lights glowed in its ceiling. In front of a closed steel door stood an alert young man with a submachine-gun cradled in his arm.

Connor nodded to him and said, "All right." He produced a key from his pocket and unlocked the door.

Not until they were inside the room, and the door locked behind them, did either Connor or Paley say another word.

Birrel's glance darted around. The room, an ice-cold concrete cubicle, had nothing in it at all but a hospital table on which lay a long something covered by a sheet. From it came a strongly chemical smell.

He felt a wave of relief. So that was why he had been brought here with all the hush-hush—to identify a dead someone? It was the only possible explanation—

"Six weeks ago," Connor was saying, "near one of our most secret atomic depots, a prowler was challenged. He tried to escape. He was shot and instantly killed."

He said then, "All right, Paley. Uncover him."

Paley went to the table. He took hold of the white sheet. His hand trembled a little, and there were sudden beads of sweat on his forehead despite the freezing cold of the room. He looked as though he did not want at all to carry out the order.

Connor's harsh breathing was loud. Birrel wondered why they were so affected. Surely not by the sight of a dead man—they, even more than he, had seen plenty of dead men in the war years.

The sheet was pulled halfway back. A naked man lay on the table, his dark eyes staring sightlessly at the ceiling.

He was fairly young, black-haired, with faintly swarthy skin and a blocky, undistinguished face. He looked vaguely familiar....

With a shock, Birrel realized that the dead man looked not unlike himself. Not a twin-like resemblance, but still, a strong resemblance.

He looked up quickly to Connor. He was amazed by the expression in Connor's heavy face. The lines in it had deepened. His half-narrowed eyes stared almost hauntedly at the dead man.

Paley had moved back from the table, and there was a strain in his gray face as he looked across the body at them.

"He was a spy," Connor said. "There's no doubt about that at all. And a very skillful one, to get into that guarded area."

Birrel asked, "From what country?"

Connor looked at him. He said, "From no country. You see, we ran a post-mortem on him, and—"

He stopped. He looked as though he didn't want to say what he was going to say, as though he had to force himself against a whole lifetime's beliefs and thinking, to say this thing.

"He wasn't an Earth man at all. He was from somewhere else. Some other world."

CHAPTER II

Birrel still couldn't take it in.

Two hours had passed, and he sat in Connor's office, listening, arguing, still not believing.

Paley was there, hunched as though half asleep in a chair in the corner. There was another man there, a young man named Garlock, with glittering eyeglasses and teeth and a sharp voice. But Connor did most of the talking.

"I know it's fantastic," he said, for the tenth time. "But it's so."

"But he looks human—," Birrel said, again.

"He is human. But he's different. His blood is a type no one ever saw before. His cells, his nervous-system, his bone-and-muscle tissue, they're all different from an Earthman's. Unmistakably. I could give you Dr. Blount's report, but it wouldn't mean anything to you. If you'd seen Blount's face, that alone would have convinced you."

"But this is 1956," Birrel argued. "We're still only talking about space-flight. And only crackpots believe in ships and people from other worlds."

Connor winced. "Don't. It's like hearing a playback of what I said to Blount. Listen. We had the two most qualified biologists in the country check that body. They agree utterly. It's non-terrestrial."

Birrel opened his mouth to say something and then shut it. He had nothing more to say.

He faced the enormity of an impossible fact, just as these men had had to face it. A man, a visitor, a secret visitor, from another world. In this hard, matter-of-fact office, it seemed impossible, like a story read and thrown away, like a crazy movie you laughed at as you went out. The George Washington Bridge was only a few miles away, and tomorrow the Giants played the Pirates, and Friday was payday, and a man had come from another world.

"But from where?" Birrel whispered, finally. "And why?"

Connor sighed heavily. "Now we're getting somewhere. I know how hard it is to take. Every morning I wake up, I think at first it was just a wild dream—" He broke off, then said harshly, "From where? We don't know, haven't an idea. The sky is full of worlds. Take your pick."

A nightmare kaleidoscope of all the stars and planets of the universe rushed through Birrel's head. The sky is full of worlds. Yes. He'd never quite realized it before.

"As to why, there's no doubt at all," Connor was saying. "The man was killed near one of the most heavily guarded atomic weapon depots we have. He was killed trying to escape. He was a spy."

"A spy, for—" Birrel's voice trailed away.

"That's right, Birrel. For someplace else, someplace not on Earth."

Garlock spoke up to Connor, interrupting. "You're giving it to him too fast, John. It took us weeks, and yet you haul him in and hit him in the face with the whole picture. More time—"

"I'm running this, and we haven't got more time," Connor said roughly.

Birrel hardly heard them. He felt as though an earthquake had rocked his mind, had shaken up all his preconceived ideas, all the bases of his thinking for a lifetime.

"But," he said slowly to Connor, "a spy from someplace outside, from another world—does that mean danger? A threat, out there?"

Connor spread his big, spatulate hands on the desk. "We don't know. We don't know what it means. But this agency has top responsibility for the country's safety against secret enemies. Whether they're Earthmen or not! We have to assume it does mean a threat."

"Yet it could be just accident, his being near the atomic depot?" A thought sprang into Birrel's mind. "A visitor from outside, coming secretly, wanting to learn about our science—"

Connor smiled grimly. "I wish I could think so. But we know it isn't so. Show him what we found, Jay."

Garlock went to a safe and unlocked it and took out a small object and came back. He said to Birrel,

"We found two things beside the man himself. A quarter-mile from him we found a queer burned place in the ground, a charred gouge. We don't understand it at all. The other thing we found was in his pocket. This."

He put the little object on the desk. To Birrel, it looked rather like a black plastic film-viewer of the type used for looking at colored slides. He said so, and Garlock nodded.

"That's just what it is. Only it's the someplace-else type of viewer. I'll turn it on. Then you look into it."

His nerves taut, Birrel put the lenses to his eyes. Would he look at the incredible vistas of another planet, at—

But no. He was looking at a colored picture of a big laboratory's interior, and it was definitely an Earth lab of the present day. He could name many of the gadgets in the room. It looked like an atomic experimenter's workshop, on a big scale.

Birrel got that one glimpse and then started violently and tore the viewer away from his eyes.

A man's voice had spoken, close to his ear—small in volume but rapid, authoritative, precise in diction.

The language it spoke was one he had never heard.

"What—?" he cried, startled. Connor and Garlock nodded. "The voice," said the latter, "is on the film."

"And that," Connor said flatly, "was a picture of the most secret atomic laboratory at Los Alamos." He reached out and took the viewer into his own hand. "There are fifty-six pictures in this thing, each with a detailed vocal commentary like that you heard. They're pictures—detailed pictures—of top-secret atomic depots, storehouses and arsenals."

"But how could they—," Birrel began. Connor cut him off.

"We haven't the faintest idea how. They've obviously got instruments that we don't have, for looking into places. 'Why' and 'who' are what we want to know. Especially, 'Who'."

He got up and walked back and forth in a little pattern. With a shock of surprise, Birrel realized that it was not yet midnight. It seemed that an eternity must have passed, not just a few hours.

Connor stopped and turned toward him. "That's where you come in, Birrel."

It wrenched Birrel suddenly back from his chaotic imaginings of far-away worlds and stars, of a cosmic plot and an unsuspecting Earth.

"Me?"

"You're going to help us find this ring of Someplace-else agents."

"But you said yourself you had better agents than me!"

Connor nodded. "But, as I told you, you have the right face. We went through photos of several thousand former agents to find your face, Birrel." He paused. Then—"Our only concrete lead to this bunch of whoever-they-are, is that dead man. He was one of them. If he were alive, he could be trailed back to the others. But he isn't alive. So, to find that trail, we have to use a ringer."

Birrel was numb with amazement, but he was not a fool, and he got Connor's implication instantly.

It was one of the oldest tricks in the book of counter-espionage. You had one of your own men pose as an enemy spy, so that a contact would be made that could lead you to the others. An old trick, and a risky one—even in ordinary circumstances. But in this case, it was fantastic.

"Oh, no," said Birrel. "It wouldn't work, there isn't a chance. I don't look that much like him—"

"You have the necessary basic feature," Connor said. "The skull-shape, the ears, the things that can't be disguised. Our make-up experts can do the rest."

"But how can I pose for a minute as that man, when I don't know his language? The first moment any of the others spoke to me, I'd be through."

"We can teach you a fair bit of the language," Connor said. "Enough so that you won't be instantly recognized as a fake. You'd soon be found out—but by then we'd be jumping on them."

Birrel stared, wondering if the strain of this hadn't been too much for the man. "You can teach me some of that other-world language?"

Connor said, "Grossman can. He is, in case you don't know, one of the world's greatest philologists. He was called in on this weeks ago. Using that spoken commentary on the film-viewer, that voice that each time described a specific pictured scene, he worked away relating words and pictures until he built up the whole language. It's rough yet—but he's got a vocabulary of a couple thousand words, a set of grammar-rules, and—above all—an accurate reproduction of accent and pronunciation, in that recorded voice. Enough, with luck, to get you by for a little time with the others. That should be time enough for us."

Garlock interrupted, saying heatedly to Connor, "Look at his face! I tell you, you're giving this to him too fast, you can't throw it at him like this."

Connor ignored the protest. He sat down again at the desk, and his bleak eyes held on Birrel's face.

"This is how it stands. Where they came from, what that place is like, we haven't a glimmering. How many of them there are on Earth, we don't know either. But one man couldn't come alone. So there are others. All right."

He bent forward, his harsh voice beating at Birrel. "We make you look like that dead man. We have Grossman cram you with that language till you can get by. Then we stick you in jail. We announce that an unidentified spy was caught near an atomic installation, weeks ago, and that we're still holding him for questioning. We let that out in the newspapers."

"And then?"

Connor said, "The others—they'll be wondering what happened to their boy. He was alone on that job, we're sure of that. When they hear he's in prison, they'll surely try to contact him—you."

"What makes you so sure they will?"

"Because," Connor said slowly, "they have to. This is a secret operation. They must prevent our finding out who our prisoner is, finding out that he's from outside Earth."

His voice became raw-edged. "They're a threat, Birrel. Wherever they came from, they're danger. Perhaps the worst danger that ever threatened us. We have to find them. You have to help."

He did not ask for that help, he commanded it. And with a feeling of unreality, Birrel knew that he could not disobey that command.

Connor rose. "You'll stay here, while we set this up. It'll take weeks, working every minute, to get you ready."

Weeks later, wearing another man's face, Birrel sat solitary in an isolated cell of a New York prison. He sat there unbelievingly waiting for the impossible, for the secret ones from the wider cosmos.

He did not have to wait long.

CHAPTER III

They came at ten minutes before midnight.

Birrel had been sitting in this cell for some twenty hours. The cell was deep in a jail in downtown Manhattan. It was a solitary cell, for a solitary and important prisoner.

He had a different face now, a dead man's face. The clothing he wore had belonged to that man. He could speak that man's language, to a certain extent. He was not Ross Birrel, he was a man from Someplace-else.

"What's my name, on that other world?" Birrel wondered. "I'm impersonating somebody and don't know who, or what, he was—"

Except that the man he impersonated had been a spy. Secret agent of an unguessable, distant world, ferreting out Earth's defense secrets.

A wave of cold disbelief swept Birrel. It was still too fantastic, too incredible. The scientists were wrong about that body, they must be wrong. Connor was wrong.

But Connor remained grimly convinced. Before his men took Birrel to the prison, he had said,

"They've lost an agent, those people from outside. A valuable man with valuable information. They'll contact you, somehow when our newspaper story appears."

"In a locked cell in prison?" Birrel had said, incredulously. "How can they?"

"I've an idea," Connor had said, "that they can do quite a lot of things we can't. But we'll be ready for them. The prison guards aren't in on our set-up, of course. But we'll be in the building, watching."

He had added, "You may not fool them long. But try. Remember, the important thing is to get them to lead you to the others, to the center of this thing, to their base, wherever it is. We'll follow."

That had been twenty hours ago. And now Birrel sat in the cold, stone-walled little cell, and stared at the blank steel door, and told himself that he was a fool, and that Connor was mad.

No one could reach him here, even if anybody tried.

Birrel suddenly looked up. Something had happened to the light, the single bulb that illuminated his cell.

A greenish tinge had come into the light. It deepened, and there was a buzzing in his ears, and—

Birrel pitched to the floor, unconscious.

He came out of blackness, later, with a vague consciousness of someone touching him and the sound of a voice in his ears.

It was a woman's voice, low and hurried and husky with strain. He didn't know what it was saying, the words didn't make sense—

Of a sudden, Birrel's heart pounded. Some of those words, those strange-sounding syllables, did make sense. They were words he had learned in the weeks of preparation—words that Grossman, the philologist, had beaten into him by endless repetitions.

The words—the language—of the secret ones from Someplace-else.

He wrenched his eyes open. He looked into the dark, handsome face of a young woman. Her eyes were brilliant with excitement, and her hands were shaking Birrel by the shoulders. She spoke swiftly to him again, and now his clearing mind could translate the words.

"Rett, there's little time! Please!"

"Rett?" That was a word he didn't know. But of course—that would be his name. Or, rather, the name of the man he impersonated. Rett—

Birrel was too foggy yet to try to answer, in that alien language. He was dazed, off balance, and dared not make a slip.

She helped him to his feet. His legs were like strings. He felt as though a pile-driver had hit him. What had happened?

Hanging to the edge of the bunk for support, Birrel stared groggily. He saw now that the girl wore an ordinary tan suit, with no covering on her shoulder-length black hair. Beyond her, the steel door now gaped wide open. How had it been opened? And what had struck him senseless? There had been a sudden greenishness in the light—

The light was still green, a baleful emerald tinge. He didn't understand. He looked down at himself, and found that around his neck now hung a chain from which depended an egg of silvery metal. The egg hummed.

Birrel reached numb fingers toward the thing, but the girl caught away his hand. Again in that alien tongue, she said quickly,

"No, Rett—don't touch your shield! We have to get out fast—Holmer can't blank this building forever. Please try to walk!"

His shield? Shield against what? He saw now that she too wore a humming metal egg around her neck.

Birrel's brain was beginning to clear. But he purposely kept his bewildered expression. Acting dazed would give him a little more time.

"Holmer?" he said.

"He's outside," the girl said. "Holding the"—(and here she used a word Birrel did not know at all)—"on the whole building. But we must hurry!"

Birrel began to understand. They had come indeed, the secret ones from beyond the world. One of them, outside, had hit the whole prison with some stunning force, some super-encephalographic vibration. That was what had knocked him out. But the greenish glow was still there, the force still on. How was it he was conscious now?

Was the "shield" a shield against the stunning force? The girl had put it on him, and he had revived. And she was wearing one herself—

It suddenly rushed over Birrel, the full, overwhelming realization that he was face to face with someone not of Earth. He stared into her dark, smooth face, into her wide, worried black eyes, and he felt the short hairs on his neck bristle.

She seemed utterly human and Earthly, and she was not. The eyes meeting his had looked on unguessable vistas across the cosmic abyss. The strong hands that steadied him were alien hands.

Woman not of this world....

He shivered involuntarily and the girl misunderstood that. She said urgently,

"I know you're shaken up but you must walk! We must get out of here—come—"

She tugged him toward the open door of the cell. Birrel stumbled through it, with her. His feet would not coordinate, they kept scuffling and tripping as he went down the corridor and up the stair.

There was a guard office at the top of the stair. Two jail guards in uniform sprawled, one in a chair, the other on the floor. They were not dead, for he could see the rise and fall of their chests. But they were gripped by an insensibility like death.

Birrel began to get it. "Holmer can only hold the building blanked for a little longer!" The one outside, the confederate of the girl, had stricken everyone in the prison into a coma. Protected by a shield-device, she had walked right in, unchallenged.

The thought appalled Birrel. Connor and Paley and their men were in this building, waiting to follow Birrel and whoever contacted him. And Connor and Paley and the others must right now be as unconscious as these guards. Their whole plan was shattered.

"Hurry, Rett!" She was urging him almost fiercely forward, out of the office and into a main hall.

They came to a barred door, now swinging open. How had she opened the doors, Birrel wondered? But a science that could throw this deathlike trance on a building full of men would make short work of locks.

The girl quickened her pace, urging him along faster. In a moment they came out into the darkness of the summer night, in a parking-court with a half-dozen official cars in it. The high gate to the street was closed. Just inside it was a long sedan whose motor purred softly. She ran toward it, her strong fingers clutching Birrel's wrist.

As she opened the rear door of the sedan, the flashing-on of the roof-light disclosed a man sitting at the wheel.

He was older than the girl, dark like her but with a craggy lined face, and eyes that might have been humorous if they were not so alert and alarmed. He too wore around his neck a silver egg that hummed.

"Kara, you took too long!" he said. "Any minute—"

"It took time to find him," she said. "I'll open the gate. No, Rett—you get in, quick!"

As Birrel climbed unsteadily into the rear seat, the girl—so her name was Kara?—ran and swung open the street-gate, then ran back to the car.

Birrel's mind was clearing but things were happening too fast. He heard a continuous thin, whining sound that was coming from the front seat. It came from a square black box that rested on the seat beside the driver.

The girl Kara leaped into the back with Birrel and said, "Turn it off now, Holmer—and go!"

The man at the wheel reached and touched the box, and the whining sound ceased. Then, instantly, he snicked on the headlights, and sent the car leaping out through the open gate into the alley.

Within two minutes, they were out in the glittering stream of Fourth Avenue's night traffic, heading north.

Only then did the girl turn to Birrel. She said, almost passionately,

"Rett, where have you been? All these weeks, Holmer and I almost going crazy—"

Birrel had an answer for that, all prepared. "They caught me. They questioned me, time after time. Finally, when they couldn't get anything out of me, they were going to hold me for trial."

Kara nodded swiftly. "We guessed that, when we finally saw the newspaper mention of an unidentified spy being held. They didn't suspect who you really are?"

He had his answer ready for that too. "No. They still don't dream of such a thing. They thought I was from another country here."

"But the Irrian?" Kara pressed. "What became of him?"

It took Birrel completely by surprise. "Irrian?" It was only a meaningless name to him. He had no answer for this, at all.

He said, floundering, "What do you mean—"

"Vannevan's man," she said, impatiently. "The Irrian you were trailing. Rett, try to clear your mind. Did the Earthmen catch the Irrian too?"

It made no sense at all to Birrel. All he could gather was that the dead spy, Rett, had, when killed near that atomic depot, been trailing someone. Someone called "the Irrian" and "Vannevan's man." Who was Vannevan?

He had to take a chance. He said, slowly, "I was the only one they captured."

She said again, "But what about the Irrian? Did you have to blast him?"

Birrel, his mind racing like a trapped animal seeking escape, suddenly remembered something. The word "blast" made him remember. It was the thing that had puzzled Connor's agents, the charred gouge in the ground that they had found near the dead spy.

Again, he had to gamble. Aware that it was a complete leap in the dark he said,

"Yes. I had to blast him."

Her small, strong hands clenched together. "If only you could have taken him, as you planned. If we could have taken him back, it would be complete proof of what Vannevan's doing here."

Birrel couldn't get this at all. He was bewildered, all his previous assumptions and those of Connor completely upset.

They had had it figured out, they thought. The dead man was a spy from another world. He would have colleagues, a group who had come here to search out Earth's most potent defense secrets, with some deadly purpose surely. Birrel's job, his imposture, was to lead to the others.

But—it seemed now that these secret ones, this Kara and Holmer, themselves had enemies. The dead man, Rett, had been trailing one. An Irrian. Who were the Irrians? Who was Vannevan, and what was he up to?

A sense of nightmare unreality suddenly swept Birrel. Their car was crossing lower Times Square. The blaze of lights, the after-show crowds, the winking signs—all were so utterly normal. And here, in the midst of it, he rode with a man and woman of a far world, speaking their language, talking tensely of things he didn't even understand.

Birrel felt a frantic desire to rip the door open and plunge out of the car, to run and lose himself in the cheerful crowds.

He couldn't. He'd taken the job and he had to go through with it—to find out where their base was, to find out what threat they represented.

"But I have to play it alone," he thought, with sinking heart.

Connor and Paley and the rest, who had planned so carefully to follow them, had never foreseen that stunning force that had struck.

Birrel became aware that they had crossed town and were running through the Lincoln Tunnel. In a few minutes they were on a main highway, heading north.

How long could he keep up this imposture? How long till he made some slip, some blunder—

Holmer, his voice quiet but with a sudden edge to it, said, "There's a car following us. I wasn't sure till we got through the Tunnel."

With sudden reaction, Birrel's hopes leaped. Then Connor and the others had come to in time to follow? Yet it hardly seemed possible....

"Vannevan!" Kara's exclamation was so fierce that it startled him.

"It can't be anybody else," Holmer grimly agreed. "That newspaper story about the captured spy—it drew him to the prison too, it seems."

Whoever Vannevan might be, Birrel thought, it was evident that these two hated and feared him like the devil.

Holmer gripped the wheel tighter, and the car suddenly lunged faster. He said, without turning, "You know what it means. The Irrians know now that we followed them to Earth. Hold on, we have to lose them!"

As by a lightning-flash, the shocking truth was abruptly revealed to Birrel. Two groups of secret agents, bitterly hostile to each other, playing a vast and deadly game against each other, were on the unsuspecting Earth!

CHAPTER IV

Birrel felt the imminence of onrushing danger. Danger, not just to himself, but to all his world. For in him lay the only chance to find out about the threat to Earth before it materialized.

Who their pursuers were, who the Irrians and Vannevan might be, and why they had come to Earth, he could not guess. But about Kara and Holmer, he was sure. Their colleague, the dead Rett, had had those pictures of Earth's most secret weapons and defenses on him. They, therefore, were the danger—and he must not lose them.

"Turn at the next side road!" he said to Holmer. "We can give them the slip in the back roads."

Holmer nodded. Birrel looked back. A pair of headlights swung steadily along a quarter-mile behind them.

"They're closer," said Kara.

Birrel looked ahead, saw the sign that marked a crossroad, and said, "Turn there!"

Next moment, he thought they were all three done for. For Holmer turned into the dark side road without slowing down at all, and the sedan careened on screaming tires and threatened to go over.

Birrel, slammed into a corner of the back seat, felt Kara bump against him. He held her with one arm and groped frantically for something to hold onto when they rolled over.

They didn't roll over. By scared reaction, Holmer spun the wheel at the right second. The sedan tottered, then thumped back onto all four wheels, its motor stalled.

Out on the main highway, a car flashed by fast.

"These cursed Earth vehicles!" said Holmer, in a shaky voice. "No gyroscopic controls, no built-in stability factor at all!"

Birrel felt like yelling, "What the devil made you think you could turn a right angle at full speed?" But he didn't. It would give him away, as Rett he mustn't know too much more about automobiles than the others did.

But for the sake of survival he had to get Holmer away from the wheel.

He said, "Let me drive it—since I saw you last I've learned to handle them pretty well."

Holmer crowded over in the front seat, holding the black box in his lap. Birrel climbed over fast, and took the wheel.

"They went past, but now they're coming back!" cried Kara. "I can hear—"

Birrel kicked the starter and then the gas-pedal, and the sedan shot up the dark asphalt country road like a frightened rabbit.

Kara was looking back, and her voice came clear over the rising whine of the motor.

"They're back there. Gaining on us—"

Birrel glanced up at the mirror and the headlights coming up fast behind. He jammed the gas-pedal down, sending the sedan hurtling past the lighted windows of houses, the black masses of trees. The headlights came no closer.

Kara cried to Holmer, "Use the—" Again, the word that Birrel did not know.

He knew what it meant. The square box in Holmer's lap, the thing that had stricken all in the prison unconscious by its potent vibrations.

Holmer fiddled with the box. Over the roar of the motor, Birrel could not hear it come on. But he looked up hopefully at the mirror.

The headlights stayed right with them.

"No use," said Holmer. "They've got their shields on. They must have known how we did it at the prison."

He turned the thing off. Birrel realized, with a certain desperation, that it was up to him.

He had one advantage, he thought. If those pursuing were from another world, they would not be able to drive an Earth automobile as expertly as he could.

Kara said, "They could cut us down with the"—(another totally incomprehensible word)—"but they won't dare use that here! It would let everyone in this part of Earth know they're here!"

What weapon it was that the pursuers, the Irrians, had but might not dare to use, Birrel could not guess. But the fear in Kara's voice was enough to make him conjure up nightmare visions of awful agencies and powers that might be loosed on them.

It decided Birrel. Better to take the risk of cracking up than let that car hang onto them. He would use his one advantage.

"Hold tight," he said, and turned sharply at the next side road.

Birrel began a crazy twisting and turning on the network of back roads. He had always been a good driver. Tonight, with desperate purpose urging him, he forgot all about road-risks.

He forgot about everything except the ribbon of road under his headlights, the sharp curves that he skidded around in racing turns, the instinctive feel of what grade, what dip, what crossroads, came next. It was late and the farmhouses were dark now, sleeping people in them not dreaming of what screamed past them in the night, what flight and pursuit of folk from far worlds.

The rhythm of the racing motor got into Birrel's mind, as his tension rose higher. There was nothing but the headlights and the road and the dread of what came behind them. He was sharply startled when Kara's voice broke the spell, speaking close to his ear.

"We lost them, long ago!" she was saying. "Rett, slow this thing before you wreck us."

Birrel eased the gas-pedal. Beside him, Holmer looked scared.

"These clumsy Earth cars—I'll never get into one again!" he said, with feeling.

They were running up a hillside, with scrub woods on either side of the road.

"Stop on the crest, and we'll listen," said Kara.

He stopped, cutting the motor and lights. They got out and looked back. In the soft summer night, the little woods-sounds, the monotonous song of peepers, were somehow shocking in their ordinariness, to Birrel. Impossible that it was just another July night in New Jersey, when beside him stood a man and woman not of Earth.

He looked up at the summer sky, decked with chains and hives of stars. From which dot in the sky had these two come? From where had those others come, those who pursued, the Irrians? "The sky is full of worlds," Connor had said. And the sky was full of mystery and menace....

"Yes," said Holmer. "We've lost them. But we'd better not linger here."

They got back into the car, and Birrel drove on again. Holmer said, "We'll go back to the house. We've got to decide fast, what to do—now that Vannevan knows we're on Earth. We can stay here, and keep watching them. Or we can go home, with what we already know."

With a queer icy feeling, Birrel realized that "home" meant the world from which they had come somewhere across the abyss of space. There must be a ship, hidden somewhere, waiting for these people. If he could keep up his imposture till he reached that ship, and then get word to Connor.

"Rett, you're going wrong, the other road is the way to the house!" Kara said suddenly.

They had just passed a crossroads. Birrel braked the car, and with dismay realized that he had not the faintest notion where "the house" was. Yet that was something that, as Rett, he obviously should know.

He said, "I'm sorry, it's been so many weeks. You had better call out the turns for me."

Neither Kara nor Holmer seemed to find it surprising that he should not clearly remember. But as he drove on, with the girl warning him of each turn on these far-back-in country roads, Birrel wondered how long he could maintain this impossible imposture. He had never been supposed to maintain it for long, the plan had been that Connor and his agents would be following quick and close, but that plan had been irretrievably ruined and he had to ram ahead alone and do what he could, find out what he could.

He was driving down a dark, bumpy road between untilled fields when he became aware that now Holmer and the girl were both peering more intently ahead. Birrel made out the dark loom of an unlighted farmhouse.

Was this "the house"? He dared not ask them that—as Rett, he might have forgotten the network of roads but he certainly wouldn't have forgotten this. But if he turned in, and it was the wrong place.

Birrel thought of a stratagem. As they approached the dark house, he slowed down as though to turn in. If they protested, he could explain that he only wanted to stop and listen again.

But they didn't protest, it must be the place. Birrel turned the car right into the rutted drive, with the headlights striking past an old lilac bush to the front of a ramshackle barn.

"Cut off the lights," said Holmer, worriedly. Birrel did so, his hand shaking a little. He couldn't gamble like this forever without slipping.

They went into the dark house, Kara first going through the rooms and pulling down the blinds, and then carefully lighting a kerosene lamp. They had, Birrel thought, picked a hideout far off the main roads indeed, to be without power.

The place was cold, musty, with some battered old furniture that looked as though it had been here for a long time. There was no evidence at all of how many people had been living here, and there was no evidence that its occupants were aliens from a far world. It was just an old house in the country, silent and lonely.

Birrel sat down and he was glad to do so, for his feeling of desperation was increasing. So far, he'd found out little. This house was obviously only a temporary headquarters. The real base of these people was somewhere else—but where? That was what he had to find out for Connor.

He gambled once more. He said, "Haven't any of the others been here with you?"

The others. The ones who had come with them to Earth, who must have come with Kara and Holmer and Rett to Earth, and who must be found!

Holmer, setting down his square black box on the floor, said uneasily, "Thile was down last week. He's afraid of the ship being discovered, he kept urging us to leave. I told him we couldn't, without you."

Kara came and sat down in front of Birrel. She said, "I know you've been through a lot, Rett. But we have to decide fast. Have you enough proof of what Vannevan's doing on Earth to take home?"

And this was it, Birrel thought. He had got by in the rush of their flight, but he could not possibly bull it out in a conference where his ignorance must betray him.

Holmer said worriedly, "I say, go! Now that the Irrians know that Ruun has taken a hand in this, that we've followed them to Earth, they'll never rest until they hunt down us and the ship. You know what Vannevan is like! I say, go with what we've found—right now."

"It all depends," the girl said quickly, "on what Rett has learned. Rett—"

She never finished. At that moment, quite without warning, something like an enormous hand struck Birrel and knocked him in perfect silence to the floor.

He did not lose consciousness. He was able to see the others fall too, stricken by that same silent power. Only he could see from their horrified eyes that they knew what the power was, while he did not. He tried with desperate urgency to move but every nerve was paralyzed, and he could only lie there and watch.

The door of the room opened. Two men came in, moving fast, dark ordinary men in ordinary clothes. Each one carried in his hand a thick, fluted metal cylinder. The cylinders must generate the paralyzing force which had worked effectively from outside the house, Birrel thought.

A third man followed them.

He was no taller than the others, but he was wider in the shoulders, a powerful easy-moving man. His face was the face of a man born to command, dedicated to it, living for and by it—a man to whom life without personal and immediate power over everything in sight would be intolerable. Just now he had it, and he was happy.

Holmer spoke, but his stiff lips could make only a terrible whisper.

"Irrians—Vannevan!"

CHAPTER V

There were six people in the living-room of the old New Jersey farmhouse, and only one of them was an Earthman.

It seemed a madly impossible thing, to Birrel. The year was nineteen-fifty-seven and it was twenty-five minutes to midnight on the eighth of July, and this couldn't be happening but it was.

"You were easy, easy," Vannevan was saying. "Did you think I wanted to overtake you out there on the road? All I wanted was to get close enough to pop a tracer on the back of your vehicle, and then follow you."

He was a very happy man, Vannevan. He had outwitted and beaten his enemies, and he was enjoying that part of it more than the actual capture.

He strode up and down on the old, faded carpet, but he was careful not to get in front of Birrel and Kara and Holmer.

The three sat in chairs and across the room stood Vannevan's two men. Each of them held one of the fluted metal cylinders, and each cylinder was pointing toward the three prisoners, reminding them how quickly they could be paralyzed again, or killed.

The incongruity of it gave Birrel a crazy desire to laugh. The musty old farmhouse, the smoky kerosene lamp, the ticking cuckoo-clock on the wall—and five strangers from the stars.

He wondered what a "tracer" was. He supposed it was some sort of tiny gadget that could be shot to stick onto a moving car, and broadcast a signal that could be read and followed. He doubted if he'd live long enough to find out if that was right.

Vannevan said to Birrel, "You killed Jull, didn't you?"

There was no amusement in his hard face now. It was cut out of cold iron, and Birrel had the feeling that Vannevan was every bit as tough as he thought he was.

"Who," said Birrel, "is Jull?"

"A man of Ir," said Vannevan. "My man. The man you trailed and killed. We found the blaster-scar in the ground."

Birrel began to understand a little. He shrugged. "If you know, why ask me?"

Vannevan came closer and his eyes had a yellow glow in their dark depths.

"You wouldn't just blast him outright. You'd shock him and search him first. Just as we're doing to you. Where are the"—(he used another unfamiliar word)—"you found on him?"

Birrel said, "I found nothing. I just blasted."

Something exploded in his face. He reeled in the chair, putting up his hands blindly, half-stunned. Then he saw Vannevan's clenched fist drawing back. Vannevan, keeping carefully to one side, let the fist go again in Birrel's face.

"You're lying," he said. "You wouldn't come all the way here from Ruun, spying on us, and trail Jull all that way, and then just blast him. Did you pass them on to Holmer before the Earthmen caught you?"

Birrel felt blood running down his face, and he felt a hate and rage that he had never suspected he could experience. He started to get up, and the Irrians with the weapons across the room pointed their cylinders at him. He didn't want to die, any sooner than he had to. He sat down again.

"The men of Ruun are brave," said Vannevan, mockingly. "Now will you tell me—"

He stopped suddenly. An expression of interest and amazement crossed his face. He reached out his hand, toward Birrel's eyes.

Birrel recoiled—but Vannevan's hand swiped across his forehead, across his eyebrows. Then Vannevan uttered an incredulous exclamation.

"This isn't a man of Ruun at all. He's an Earthman!"

Birrel realized what had happened. The blow, the blood streaming down his face, had effectively ruined the careful work of Connor's make-up experts.

Before he could resist, Vannevan rubbed a handkerchief across his face. Birrel, a little dazed and half-blinded by the blood in his eyes, struck out savagely but hit nothing.

Kara's voice reached him. "Rett, you can't be—" Her voice trailed away, and then it came on a different note. "But you're not Rett. He's right, you're an Earthman. Where's Rett?"

Birrel got his eyes open, and now he could see her face, and Holmer's, and the pallor of shocked surprise on both.

He felt a queer guilt. There was no reason for it, they were spies and he was a counter-spy defending his country, defending Earth, but he couldn't rid himself of the feeling.

"Yes," said Vannevan fiercely, "where is Rett? Where's the man you've been impersonating?"

Birrel looked at him and said nothing.

One of the Irrians came to Vannevan's side and spoke so rapidly that Birrel could not follow it.

Vannevan said somberly to him, "Your people—the Earth people—have this Rett, don't they? They captured him, didn't they?"

That was so obvious that there was no use denying it. "They did," said Birrel.

"And they disguised you as Rett, and published that report of a captured spy, to draw the others," Vannevan said, "Of course. Which means—they know there are strangers on their world."

Holmer said, with a taunt in his voice, "You don't like it, do you, Vannevan? It spoils the plans of Ir, doesn't it?"

Vannevan looked at him. "No. There will be no check at all in the plans of Ir. And when we've got what we need from Earth, our plans for your world will go right ahead. Be sure of that."

Birrel's mind vainly tried to grapple with the hint in that byplay. Then this was not merely a personal enmity, or a factional one? Then the world of Ir and the world of Ruun—wherever those far worlds might be—were enemies? Then the Irrians, at least, had come to Earth secretly for something they needed for conquest?

It didn't make sense! These star-strangers had already used weapons far subtler and more complex than any weapon of Earth. Why would they need to filch the arms of a less scientifically advanced planet?

"You can wait," said Vannevan to Birrel, with a certain contempt. He turned and looked at Holmer and Kara. "But you two are important. No word is going back to Ruun of our plans! Where is your ship hidden?"

"Where is the ship of Ir hidden?" countered Holmer.

Vannevan smiled grimly. "Where you couldn't find it. And you've tried long enough, haven't you? This planet has a lot of wild places. Which one is your ship hidden in?"

Holmer merely laughed.

"You'll tell, one of you," promised Vannevan. He spoke to the Irrian beside him. "The man, first. Take him upstairs. He'll talk more freely and readily if she can't hear him."

The other man pointed his weapon at Holmer. Holmer, without a look at Kara or Birrel, started up the old stairway in the hall, with the Irrian close behind him.

Vannevan followed them.

Birrel looked at Kara. Her face was a stony mask. He looked at the Irrian across the room. In the yellow light of the lamp, the man's face was wrong. It was wrong because it was just a dark, average face. It didn't belong to an enemy from the stars. But the cylinder in his hand pointed levelly at Birrel and the girl.

The dusty cuckoo-clock ticked toward midnight. Strange, that it was running, Birrel thought. One of them—Kara or Holmer—must have started it out of curiosity.

He knew he was only thinking these thoughts so that his brain wouldn't crack from the insane unreality of the situation.

Birrel suddenly felt sweat on his forehead. Sounds were coming from upstairs, not loud sounds, but thumping, gasping noises. There was a voice, and then more of the gasping sounds.

Kara started to get to her feet and the man with the fluted metal cylinder said, "Sit down."

Birrel looked at the clock. Two minutes to midnight. A cuckoo-clock and a spy from the stars. Unreal. But a wild notion began to grow in his mind....

A shriek, a fading, choking death-cry, came down the stairs. And then Vannevan's voice came down, loud with anger.

"Damn him, he's dead."

"Sit down," said the armed Irrian, again.

A half-minute to midnight. He'd have to try it, there'd never be another chance, not after Vannevan came down those stairs for another of them, for Kara first, and then for Birrel—

The cuckoo-clock said, "Cuckoo."

At the sharp sound, at the little flirt of movement by the out-popping bird, the Irrian with the weapon looked up, startled.

Birrel had thought he would. He thought it unlikely that they had cuckoo-clocks out in the stars. He had waited for the moment, and as the Irrian's head turned, he sprang.

He didn't try to reach the Irrian himself. He was too far off. He went for the table with the kerosene lamp on it, which was quite near. He hooked his fingers under the edge of the table and heaved it over as hard as he could. The lamp went flying. It hit the floor, splashing hot oil and flame, and the Irrian screamed. The carpet was suddenly burning around his feet and little flames blossomed like magic where the oil spattered his clothes. There was no need for Birrel to tackle him. He fled screaming into the hall, tearing off his coat and beating in panic at his legs.

The room was in darkness now except for the splashes of fire that ran over the floor and up the window curtains and in erratic streaks on the wallpaper. Birrel grabbed Kara's hand and lunged for the outer door.

"Holmer!" she cried frantically, dragging back.

"He's dead, you heard—come on!" He pulled her, with rough determination.

They banged out over the sagging porch-floor into darkness, and he ran, not toward the car but toward the brush beyond the house, the black thickets that promised protection.

He looked over his shoulder and saw the leaping red glow spreading fast inside the grimy windows. The screams of the Irrian had sunk to a kind of groaning, and Birrel could hear Vannevan's fierce voice over it.

He kept tight hold of Kara's wrist, and now they were in the thicket, moving through saplings and brush. Then Birrel stopped.

Back there, three dark figures had come out of the house. Two of them were twined together, as though one half carried the other. The third was alone and in the lead. They stood silhouetted against the glowing windows, looking this way and that.

Birrel whispered to Kara, "Quiet. If we try to get any farther, he'll hear us."

"They will search until they find us," she whispered.

He shook his head. "That house is beginning to burn nicely. I don't think they'll stay here long."

He felt her gesture of negation. "I don't understand."

"We have a thing on Earth called a Fire Department. In the country every man is his brother's fire warden. Pretty soon the place will be swarming with trucks and volunteer firemen. Stand still and wait."

They waited.

Vannevan and the men spoke together. Finally they left the hurt one to groan and crawl in the grass, and the two of them began to move back and forth in the brush, circling out.

A great plume of flame shot up through some air-shaft in the house and stood out gloriously above the roof.

Vannevan and his man had vanished now in the brush. Birrel held Kara's hand and sweated, and prayed for a sound.

It came. The hoarse, harsh wailing of a country siren, designed to waken every sleeping volunteer in the township.

It rose and fell on the night air, ominous and loud. Vannevan and his man hastily reappeared in the shaking red light. They picked up the hurt man and took him limping away between them. They went down the dark road. Presently, in the distance, Birrel heard a car start.

When he could not hear it any more he said, "All right, let's go."

And he took Kara away across the dark brushy fields running, stumbling, toward a future whose incredible outlines he was beginning vaguely and against his will to see.

CHAPTER VI

They sat together in a brushy hollow by a stream. Frogs chorused in the marshy spots. The stars swung overhead, above the dark trees. Close by in the warm night an owl sang a weird fluttering song to his love, and there were crickets.

Birrel and Kara spoke of things so strange and far away that they were doubly unbelievable in this setting.

Birrel was stubborn. "I've got to take you back to Connor." He had explained to her who Connor was. "He'll study the facts and decide what to do. After all, you've got to remember that Earth is our world. It's more important to us than any other."

Kara was stubborn, too. "The threat is not against your Earth! It's against Ruun, my world. I told you—"

"But your man Rett, the real Rett—he had that probe-ray record of our most secret atomic installations on him."

"Of course he did," she said angrily. Birrel gathered that she had liked Rett, not romantically but as a good comrade in arms. She had taken the news of his death rather hard. "Why do you think he was there at all? He took that record from the Irrian. It was the proof we needed of the Irrians' activities here, so that our government back home will act before it's too late. If your people hadn't shot him, everything would have been arranged by now. As it is, it's worse than ever."

"Look," said Birrel. "I want to believe you, Kara. I do believe you. But it's just too big a responsibility for me to take on my own shoulders. Connor—"

"Connor!" she said contemptuously. "You're afraid."

"Yes," he said. "I'd be a fool if I wasn't."

She put her head between her hands and said in a very patient voice, "I am trying to remember your side of it. Now listen to me once again. There is a star—you call it Wolf 359. It has several planets, of which five are inhabited. We, the people of Ruun—"

"Control four of the five planets," Birrel said, not without a faint edge of skepticism for the story he had already heard from her.

"Peaceably," she said. "The other three worlds allied themselves with us voluntarily. They are completely autonomous. But they are less favorably situated than Ruun and they can't support large populations, so they're relatively weak. And they wanted a strong friend, rather than a strong master—like Ir. Would you enjoy living under Vannevan?"

He had to admit he would not. "But are the Irrians all like him?"

"Of course not," said Kara. "But Ir, the fifth world, is ruled by oligarchs, of whom Vannevan is one. The people of Ir may not like it—indeed, we've heard some of them don't—but they're pretty well held down."

But still, Birrel thought, both parties to this interstellar quarrel were strangers to him. And anyway, the decision was not his to make.

He said so, and she said, "But it is yours to make. Nobody else can make it. There isn't time."

She plunged on desperately, trying to make him understand. "For centuries we've fought the Irrian oligarchs to keep them from dominating the whole system. The only time we had any peace was when the oligarchs took to fighting among themselves for power at home. Because of that struggle, many years ago they finally exhausted every bit of fissionable matter on Ir. We were able to prevent them from getting any more from our federated planets, and so for a long time there has been peace. You see? We had atomic weapons, they had not. They were no longer any danger. And of course we didn't need our strong military forces any more. All we've had for decades is just enough to act as an interplanetary police force. And now—"

"And now the Irrians have stolen a march on you," Birrel said. Kara had explained the significance of that probe-ray record, and he had to admit that it seemed to make sense. "They've decided to steal fissionable material from Earth. So they sent Vannevan and his men here to spy out our installations preparatory to raiding them. And if that doesn't constitute a threat to Earth I don't know what does."

"But the weapons they make won't be used against you!" she cried. "They'll be used against us, and unless we can mobilize in time we won't have a chance."

"Look," said Birrel. "Connor will see to it that our installations are so heavily guarded that no one can raid them. Then there's no threat to either of our worlds."

She groaned, as though in despair at trying to deal with an idiot. "Your prison was strong and carefully guarded. Did we have trouble breaking into it? Would we have trouble breaking in anywhere? Guards consist of men and electronic devices. We can blank them both, in many different ways. So can the Irrians. Your defenses wouldn't hold."

And Birrel realized with a sinking heart that that was true.

"But we've got to fight. We've got to do what we can."

"Yes. Of course you do. And there is only one way." Her voice was eager now, forceful, hammering home her points with relentless logic.

"Come back with us to Ruun. Tell the authorities what you know, what you have actually seen. That will be enough to make them believe and mobilize. Vannevan and his men are only the forerunners here. A small fleet must come from Ir for the actual raid. Ruun can stop them, you cannot. You understand? Your defense is out there!"

And she pointed at the glittering sky above the trees.

Birrel followed her gesture and thought, Oh Lord, I can't! I'm scared. How far is Wolf 359? I never even heard of it.

And then he thought, But she's right. Connor, all our armed forces—we'd be like babies against a fleet from Ir. We have atomic weapons but we'd never have the chance to use them. It would be just as it was at the prison—

He listened to the owl and the crickets and the gurgle of running water, and smelled the cool sweetness of the summer night and dug his fingers into the grass because he wanted to hold on to Earth and all that was familiar.

But overhead the stars glittered and shone, and there was a decision to be made.

"If you want to fight for your world and your people," said Kara softly, "you must have courage to do what you know is right, even if it is against orders."

Yes, thought Birrel. Yes, indeed. Have courage.

Well, the whole thing had gone wrong from the start. He couldn't see that he would make it any better by delivering Kara to Connor. The chances were she couldn't be made to tell anyway where the ship from Ruun was hidden, and it would undoubtedly take off at the first hint of danger. And in any case, it seemed that the Irrians were the threat to Earth, and she didn't know where their ship was. If Kara was telling the truth, the resultant delay might be fatal to both their causes. He thought she was telling the truth.

Very quickly, before he could change his mind, he said, "It seems I have to go with you to Ruun."

"Good," she said fiercely. "Good! Then we have a chance." She jumped to her feet and tugged at him impatiently. "We've wasted too much time already. Let's go."

"Now hold on," he said. "We'll make better time if we plan ahead. Where is your ship?"

"North. In a wild place beyond a big body of water—I think it's called the Hudson's Bay."

Well, if you wanted to hide a spaceship, Birrel thought, that would be as good a place as any. But it was the devil of a long way off.

"How did you get down here?"

"By hopper."

"By what?"

"Hopper. A small flier for planetary hops. It's hidden right here in the woods. We made a shelter for it as soon as we got the farmhouse and flew it in by night. Before that it was in some mountains where we first landed. Come on."

And there was no problem. No problem at all. You found the camouflaged shelter in the summer woods and you got into the neat impossible craft that was in it and watched a girl in a tan suit manipulate a couple of controls with the casual ease of a teen-ager using a record-player. Some quiet force—compressed air, Birrel thought, remembering experimental aerodyne models he had seen—lifted the hopper high and took it away, and the last red coals of a smouldering farmhouse winked in the black countryside and were gone.

By dawn they were far north and rifling with incredible speed through the sky, at a fantastic altitude. Any radarman who chanced to catch them on his screen would lose them so fast he would never believe he had seen anything. And Birrel now knew a lot more about Kara and her people than he had.

Kara's father had been a high officer in Ruun's intelligence service in the days when, according to her, the existence of four peaceful planets hung on its efficiency. She herself, as a kind of proud inheritance, also belonged to the intelligence service, which in these later times had dwindled to a small and neglected group of people dedicated to not trusting the Irrians.

It was these intelligence people who had discovered the departure of the Irrian ship for Earth and deduced the reason for its going. But official Ruun had refused to be hustled into a panic. They were not going to put four planets on a full war footing, with all that implied, merely because a ship had made the voyage to another solar system. Rather, they thought, this star voyage might well be the beginning of a new era in peaceful expansion, with the Irrians finally taking a place in a civilized community of worlds. They had allowed a shipload of agents from Ruun to follow and check on the Irrians, but no more. And any future action would be determined by what documented information they brought back.

Kara's people had been forced to lose a little time while they learned the language and customs of the part of Earth they had business in, well enough to get by. They had done this—as presumably the Irrians had too—by adapting their televisors to receive terrestrial broadcasts which they could pull in from amazing distances, and then staring at them for hours at a time with the help of a philologist and a social scientist. Then, when they came south after the Irrians, they had been able to slip quite easily into the polyglot life of New York, which is accustomed to accents and odd ways.

"There's the ship," said Kara suddenly.

She had brought the hopper down in an express-elevator plunge and was pointing at a wedge-shaped piece of barren land between two rocky arms at the base of a mountain. The light of the rising sun made a sort of dazzle in the air, but apart from that there was nothing.

"I don't see any ship," he said. "Where?"

"I forgot, you don't have the refraction-type camouflage. When you're used to it you can spot it without a scope, if you know where to look. Here." She made rapid adjustments in a small gadget like a camera view-finder. "This is tuned to our chosen vibration rate. Makes it harder for an enemy to find us."

Birrel looked into the 'scope and saw a slim silver spire standing on the flat land, its nose pointed toward the sky.

He looked out the port again and saw nothing.

"Light rays bent in a magnetic field around the ship," she said. "They'll drop it now. Watch."

She depressed a switch, activating some automatic signal system. The dazzle of sunlight vanished and the silver ship was there. She landed beside it.

She stepped out and waited for Birrel to follow. He hesitated, looking at the ship. A hatch opened and a magnetic grapple dropped down toward the hopper. Below, a much smaller hatch appeared and extruded a ladder. Once he climbed that ladder, Birrel knew, he was trapped. The ship would take off and—

"There's nothing to be afraid of," Kara said, smiling.

He set his jaw and went with her to the ladder and climbed it and passed into the ship.

It smelled like a submarine, of oil and metal and canned air. There was a man in an odd-looking coverall who stared at him and spoke to Kara. He heard Kara explaining, and in the meanwhile the lock door behind him was grinding shut and locking itself with relentless precision.

Kara said, "This is Thile. He commands the ship."

Birrel shook hands with him. He was a small lean man with very keen eyes and a hard competent jaw.

"So Holmer and Rett are both dead," he said, with grim regret. "Well, we'll make Vannevan pay for them. Help him strap in, Kara. We're taking off at once." He looked at Birrel. "If we can get back to Ruun without delay, you may be able to convince our sheeplike leaders in time. I hope so."

He hurried away somewhere forward—or up. Kara took Birrel into a small cabin where there were several padded couches, and helped him secure himself with broad webbing straps.

"Scared?"

"Not a bit."

"Liar. Don't worry about it. The first take-off is always the worst." She leaned over impulsively and kissed him, ludicrously like a mother tucking a fretful child into bed. The ship suddenly gave a great roar and a quiver, and a raucous horn began to sound. She scrambled into the couch next to his.

Birrel's heart pounded wildly and the blood in his veins turned cold and thin as water.

There was noise. A stunning, deafening crescendo of it. Then there was a feeling of motion. He lay on the top of a rising piston that pressed him slowly and relentlessly against air compressed into a smaller and smaller space. He opened his mouth and yelled in panic fear, seeing himself crushed into a flattened pulp. The cry was lost in the bursting roar that enveloped the ship. Ages passed. And then miraculously the pressure eased and finally was gone.

Thile's voice came suddenly from a speaker in the wall. "Trouble, Kara. Radar says another ship has taken off from Earth, right behind us."

Birrel heard her quick, fierce exclamation. "So Vannevan was watching his radar for our take-off. I knew he'd never let us get back to Ruun if he could help it!"

CHAPTER VII

They were all in the ship's bridge now. Thile and Kara and a young man named Vray were conferring tensely with the radarman and checking a bristling array of instruments.

Birrel was looking at space.

The ports on one side were shielded against the sun, so he couldn't see it. Earth was behind, or below them, so he couldn't see that either. All he could see was nothing, an infinity of it, without top or bottom, front or back, beginning or end. The stars floated in it, by the millions and billions, like shoals of fiery fish gleaming red and gold and blue and green, white and violet, orange and dull crimson. They were not crowded. There was plenty of room between them. The eye was drawn farther and farther into those distances and the body unconsciously tried to follow, until the mind recoiled from the edge of some psychic calamity and screamed for solidity. Birrel spun away from the port and grabbed hold of a stanchion and stood with his eyes shut, sweating and shaking as though he had just run a race.

Kara said, "It gets you, doesn't it?"

He indicated that it did, beyond words. She nodded.

"It's no different with us. We look up at our summer skies just as you have, and dream about what it's like. We read books and we see pictures. But you can't know until you actually get out into space and see it for yourself. And I don't think you ever get over being awed. I never have."

Birrel opened his eyes again, but kept them firmly fixed on the inside of the bridge. Thile and Vray were still hanging over their instruments, looking grim.

"That ship," said Birrel. "It'll try and catch us, I suppose. Stop us from getting word to Ruun."

"I can't imagine Vannevan letting us go without a fight." Her voice was not exactly frightened, but it had a sort of clipped tightness about it that was far from carefree.

"Can he? Catch us, I mean?"

"The Irrians are good spacemen, and their ships are about as fast as ours. But Thile is a wizard. He can outfly anything in space."

Thile heard her and looked up. He said sourly, "Thanks. But you might as well tell him the truth. Vannevan is not going to rely on speed and skill alone, but on weapons. And we're not carrying any atomic armaments. The government brains didn't think it was wise, considering that we were trespassing on a strange world and might conceivably have an accident, such as falling into a city. They're thoughtful that way."

"As an Earthman, I appreciate it," said Birrel. "You have conventional weapons, don't you? That's at least an equal footing."

"We're not used to them," Thile said. "They are. But we'll do our best. Believe me."

He glanced at Vray and nodded.

"Stand by for translation."

Birrel looked at Kara.

"That only means," she said, "that we're going faster."

"How much faster?"

"Well, just at first," she said, "about double the speed of light."

Birrel stopped trying to go along intelligently with any of it. He just let it happen.

The lights inside the ship dimmed and burned blue. There was a screeching whine that rose up and out of hearing, clawing at the nerves as it went, and then there was a moment of awful vertigo when the ship and everything in it seemed to slip and fall sideways in an insane fashion.

The open ports slid shut automatically. Just before they closed Birrel caught a glimpse through them of the stars he had been looking at only a few moments before. They shifted, streamed like burning rain, and vanished, to be replaced by squiggling lines of lights.

Then the ports were shut and there was nothing except the personal sense of disorientation to show that anything had happened.

Complacently, like one who knows he is dreaming and that therefore these strange things are not really happening and so need not be taken seriously, Birrel listened to the voices of the men, speaking technical words of no meaning to him as they went through what was apparently a routine check. Then the radarman said,

"They're right with us."

Thile grunted. "Full acceleration," he said. "Build up as fast as you can. Maybe their generators aren't as good as ours."

The whining began again but on a different note. Birrel pictured himself inside an iron egg flying through space—what kind of space?—at double, triple, quadruple the speed of light. He erased the thought from his mind as quickly as he could. He said to Kara,

"Why haven't people done more star-travelling? You obviously have a workable drive."

"We haven't had the time until recently," Kara said. "The Irrians kept us too busy. Then the few exploratory trips we did make to neighboring systems were discouraging. In most cases the planets were uninhabitable, and the ones that did have life forms were pretty awful. Our government hasn't encouraged star flight. I think they're afraid of what might come flying back our way."

The ship quivered and trembled. Birrel thought he could almost feel the atoms crawling in the metal under his hand.

"Do you ever hit things?" he asked. "Like stars, I mean."

"Not very often. But I believe the results are quite spectacular. You become a nova almost at once."

He laughed. He did not ask any more questions.

The whining levelled off at last, refusing to go any higher. A collection of needles steadied on the main control-board.

Vray said, "That's it."

The radarman shook his head and said, "They're still with us."

The lines deepened in Thile's face, turning it grim and hard.

"Action stations. We'll try and get them before they get us."

Birrel said, "What do you want me to do?"

"Back in your bunk and strap in. This is liable to be rough."

He shook his head. "There must be something I can do."

"You'd only be in the way," Kara said. She was already removing a protective panel from a control-board ominously marked in red. She smiled, to take the sting out of the words. "You'll need a vac-suit. Here, Rett's will fit you."

She took a baggy-looking suit and a plastic helmet out of a locker and handed it to him. The others were putting on similar suits, leaving the helmets open. Birrel said, "Why?"

"In case we're hulled. If you hear the warning-horn, clap your helmet shut. Fast."

She showed him how and then practically pushed him out of the bridge. He shuffled back to the cabin and lay down on the bunk, feeling worse than he had at any time since the beginning of this hare-brained venture. He was scared, and he didn't mind admitting it. If he had been able to do something, anything at all, it wouldn't have been so bad. But just to lie here alone in this completely incredible ship, thinking of the completely incredible but perfectly real destruction that faced him—that was something no man ought to be asked to do.

He did it.

He was able to sense the "feel" of the ship, and from that to gauge the variations—the slight recoil and shudder as missiles presumably were launched, the greater perturbations of what could only be the near-miss blasts of the enemy weapons. It occurred to him that what these star-folk meant by "conventional weapons" were probably not at all the simple explosive types referred to by that name on Earth. The technical problems involved in launching any kind of missile at all at light-plus speeds were so far beyond him that he didn't even try to figure them. But there was no doubt that it was being done. Every leap and jar of the ship told him that unmistakably.

Even so, Birrel was not prepared for the suddenness and violence of what happened.

There was a crash. He felt it physically and heard it, too, this time, transmitted by the ship's air. He fell upward against the straps as the gravitational axis of the ship was brutally reversed. The lights dimmed to an eerie blue and there was a horrible tortured howling of overtaxed generators. The ship rammed through into normal space with much the same effort as of a speeding car hitting a stone wall, only greatly magnified. Birrel heard the warning-horn start. He clapped his helmet shut, and then inertia flung him into the recoil couch as into a slab of granite and the joints of the ship began to spring around him. Then everything was dead, generators, horn, everything. The ship was silent except for one sound, the hiss of escaping air.

Stunned but still, incredibly, alive, Birrel unfastened the straps and floated out of the couch.

The ship was still moving, but there was no longer any gravity field to speak of. Birrel was in free fall. He floated like a great clumsy balloon out of the cabin and toward the bridge, clawing his way while the ship bent and wavered and wobbled around him, its rigid frame gone limp. As limp as his own body felt. Currents of escaping air whirled papers, garments, pieces of equipment, bits of wreckage wildly around in the interior. He was in a panic lest his helmet be cracked or his suit torn.

The bridge was a shambles of buckled steel and shattered glass. The radarman was crumpled among the remains of his equipment, which had toppled and crushed him. Thile, strapped into the pilot's chair, was stirring feebly. Birrel looked frantically around for Kara.

She was strapped into a recoil chair in front of the fire-control panel. He thought at first she was dead, but when he looked closer he could see that she was breathing. There was nothing he could do for her at the moment and she was safer where she was, so he left her and went to help Thile. There was no sign of Vray at all, except for a few small red icicles formed on the edge of a jagged rift in the hull through which everything movable in the bridge had already been sucked.

Thile's voice came faintly through the helmet audio. "I told you they were better shots."

"Are you hurt?"

"Are you?"

"I don't know yet. Haven't had time."

"Nor me," said Thile. "I can stand up, so I guess I'll live." Blood was trickling from his helmet. He snuffled at it and made futile pawing motions at his helmet. "Well, that does it. Vannevan's won hands down." He swore, a dejected and bitter man. "Four good men dead, and all for nothing. It wasn't even a good try."

He pointed through the riven wall, to the black peaceful gulf beyond with the far stars shining in it.

"See there?"

There was a ship, matching its pace to the slow drift of the derelict. From its slim belly a much smaller craft dropped and jetted fire.

"They'll be aboard us in a few minutes."

Remembering how Vannevan had conducted his questioning at the farmhouse, Birrel could see little hope. If he and Thile and Kara were going to be at Vannevan's mercy, they might better have gone the way of Vray and the radarman.

Unless—

"Listen," said Birrel suddenly, "Listen, there's one thing we might do." He went over to Kara and shook her until she opened her eyes. "There isn't much time, you've both got to play along with me or it won't work. It might give us an edge, to use against Vannevan. Listen—"

He spoke rapidly, forcefully, and they listened, while the life-boat of the Irrian ship came closer, riding its fiery jet across the black gulf outside.

Thile said, "It might work—"

"It'll be dangerous," whispered Kara. "If he finds out—"

"I don't figure I have much to lose anyway," said Birrel dryly. "Hurry up!"

When Vannevan and his men came into the broken ship they found Thile and Kara clinging quietly together, apart from the Earthman Birrel, who was strapped into a recoil chair with his hands bound tightly behind him.

CHAPTER VIII

There were six of the Irrians, counting Vannevan. They wore vac-suits and they were all armed. Two of them went immediately to Thile and Kara and searched them for weapons, but they had none. The time for resistance was past.

Another man, on Vannevan's instructions, began to tear open the lockers that were still intact, looking for papers. The others stood guard. They handled themselves easily, experts at null gravity.

Birrel looked at Vannevan and said sourly, "Out of the frying pan into the fire. I don't know which of you is worse."

Vannevan's eyes were bright, cruel, competent and happy. Very happy. He had wiped out, and with interest, the defeat he had suffered at the farmhouse. He had crushed the Ruunites completely. For him, it was a good day.

He smiled at Birrel. "You see what happens to meddlers."

"I wouldn't call it meddling," Birrel said. "We caught a spy. It was natural to want to know who he was working for, and why."

"When you found out," Vannevan said, "why didn't you report back to your superiors? You were free. I remember distinctly that you were free."

Birrel indicated Kara with a savage movement of his chin. "She talked me out of it, damn her. With a gun."

"So," said Vannevan, and smiled, and shook his head. "But she had no weapon. I myself had seen to that."

"She had one," Birrel said bitterly. "In the hopper. She told me there was another car hidden there for emergencies, and like a fool, I believed her. Instead there was that flying-thing, and she pulled a weapon from inside it. The next thing I knew I was aboard this ship, a prisoner. They were going to take me back to Ruun whether I wanted to go or not."

Kara spoke sullenly. "His people killed Rett. It was the least we could do."

"Listen," said Birrel, struggling angrily against the straps that held him. "I don't give a curse what quarrel you have between you. I don't care if you blow each other's worlds out of the sky. I'm an Earthman. I don't belong here. I—"

He looked around at the broken ship, at space gaping monstrously beyond the riven hull. It was not difficult for Birrel to let an expression of fear come into his face.

"I want to go back," he said.

Vannevan looked at him. "How badly?"

Birrel would not meet his eyes. He muttered, "Bad enough."

"Well," said Vannevan. "We'll see." He motioned to one of his men. "Cut him loose. Did you find anything?"

The Irrian who had been searching shook his head, and Thile said, "I could have told you. We don't keep written records."

Vannevan shrugged and said, "Let's go."

They floated gracefully through the ship, with Birrel lumbering and floundering in their midst. They passed through the airless lock and into the life-craft. In a short time they were being taken up into the belly-pod of the Irrian ship, and a little while after that Birrel found himself a prisoner with Thile and Kara in a locked cabin.

The ship paused only long enough to finish the destruction of the derelict. Then it went into overdrive, on its way to Ir.

During the rest of the voyage, knowing full well that they were being watched, the three kept up their pretense of hostility. But Birrel came more and more to admire Thile and Kara. They were personally defeated and in a desperate situation. Their mission was a failure. Their world and way of life, which had hung on that mission, were threatened with destruction. But they clung quietly to their hope and courage and never whined—in striking contrast to Birrel himself, whose part called for constant complaint.

Birrel thought he was establishing himself sufficiently well as a frightened man who might be talked into doing almost anything for the right reward. He hoped so. Because not only his own life but the lives of Thile and Kara depended upon that, not to speak of the safety of several worlds, including his own. He was a little upset to discover that Kara's safety loomed larger in importance than anything else. He decided then that he was in love with her.

There came finally a time when the warning rang, and the lights burned blue and the ship shuddered, and then the port unmasked.

"We're out of overdrive," said Thile. "We're there."

An awe fell on Birrel as he looked out the port with them. The ship, in normal space again, was sweeping in a curved pattern toward a sun whose diamond incandescence eclipsed the stars.

Almost lost in that overpowering glare, three points of light swung far on the other side of this system. It was toward the biggest of the three that Thile and Kara were gazing.

"Ruun," whispered Kara. "If they only knew, if we could only get a message to them—"

Thile said bitterly, "What good would it do even if we could send a warning? Our cautious government would merely say, as they did before, 'You have no proof that the Irrians mean war, and without proof we cannot act'."

The ship swung on in its landing-pattern and now, below, Birrel saw a planet coming up toward them.

It was a scarred world of black-and-green. He thought at first that these were land-and-water divisions, but as they went lower he saw that they were not—that the green were fertile plains but that the ominous black areas were utterly lifeless lands, black and blasted and barren.

"That's what the oligarchs of Ir have made of their world," said Kara. "Those burned-out regions are the scars of their wars between themselves. And now, with no fissionable matter left, they must go to space for the means of destruction!"

The ship went down toward one of the wide green areas. There was a city here—a far-stretching grimness of gray, massive buildings, with a movement of hoppers and ground-cars over and through it. A spaceport lay outside the city, with the silver towers of many ships there flashing back the diamond sun.

They felt the landing. Then there was silence. They waited for Vannevan to come, but he did not. Instead, armed Irrian guards came and marched them out of the ship onto a blackened concrete apron. They stood there for a few minutes, in a chill wind.

Birrel thought, shivering, "Not Earth, this world I stand on. Not my own world—"

The diamond blaze of sunlight was wrong, the color of the sky was wrong, the too-light feeling of his body was strange. The silver ship behind them, the great gray city ahead, all wrong, queer—

"Remember your plan," whispered Kara.

Birrel steadied. He had a part to play, and upon how he carried it through might depend their last slender chance. He played that part now.

He gave a vivid imitation of a man who was in a panic. He looked up at the sun and cried out and shut his eyes, and then opened them again and looked wildly around him. Then, crying out in a voice edged with hysteria, he broke back toward the spaceship.

The guards grabbed him and hauled him back. He told them shrilly, "I can't stay here, I won't stay—I want to go back—"

The Irrian guards laughed at him. When a covered vehicle not unlike a light truck came speeding up, they shoved him and Kara and Thile into it and got in after them, still laughing.

As the truck sped into the city, Birrel shivered, and looked at everything in a numb, scared way.

The city was as grim as it had looked from afar. The gray, utilitarian cement building-material used universally did not make for beauty. The men and women in the streets were mostly in a drab sort of coverall garment that was not beautiful either. Birrel saw them looking at the truck and guards as they passed, and he thought there was a sullenness in some of the watching faces. He remembered what Kara had said, that many of the Irrian people were discontented with their oligarchs' rule but were held down tightly. He thought they looked it.

The truck turned finally into a courtyard and stopped. Heavy gates were locked behind it. Birrel and the others were ordered out. He managed to get close to Kara and give her hand a reassuring touch. Then they were taken inside a building made of greenish stone, instead of cement, with ominous-looking horizontal slits in the walls in place of windows.

Inside, without a word of explanation, they were separated. Thile and Kara were marched away up a stairway while Birrel's guards took him on down a main hallway. The hall was painted a utilitarian gray and it had guards stationed at regular intervals. About halfway down there was a door with a double guard in front of it. Birrel's armed escort stopped him here, spoke to the guard, who spoke to someone inside by means of an intercom with a small video screen. Presently the door opened and Birrel was ushered inside.

Vannevan sat at one side of a big square table. A second man, older than Vannevan and that much more experienced in the ways of those who wage war out of choice and not necessity, sat behind it. His face was a mask, his curiously opaque eyes watching Birrel narrowly as the guards were sent away.

Vannevan said, "This is our Earthman." And to Birrel he said, "This is Wolt, our Minister of Defense."

Birrel refrained from making the obvious comment. From here on he was on his own and had to be careful. Any hope of advantage he might gain by making the Irrians think he was their not unwilling tool could be lost by a single incautious word.

"I understand," said Wolt, "that the Ruunites kidnapped you and brought you into space by force."

"They did."

"A serious act. And I understand that you are quite anxious to return to your world."

Birrel said eagerly, "Can I, is there any way? I can't take this, space and stars and a world I never saw, I've got to get back—"

He saw Wolt and Vannevan watching him keenly as he babbled in pretended hysteria, and he thought they looked satisfied by what they saw.

Wolt said, "Some of our ships will be going back to Earth on a mission. You could go back with them, if—"

"If?" prompted Birrel eagerly.

Vannevan answered. "You're a secret agent of a great Earth power. You could assist our mission."

Now Birrel's face became apprehensive, cautious. "Just how do you mean that, Vannevan? Listen, I want to go back, sure. But I'm not going to betray any secrets or help you steal plutonium or—"

Wolfs hard voice cut in. "Let's consider the situation realistically. The loss of some fissionable material will make very little difference to Earth, with its enormous resources. Isn't that so?"

Cautiously, grudgingly, Birrel said that he couldn't see that it would make much difference, no.

"Now you must accept one fact. No matter what you as an individual may or may not do, we are going to take those materials. The very life of our planet depends on it. You understand that?"

"Yes."

"Very well. Now the decision that faces you is this. Will you be doing your world a greater service by denying us the information we want and thereby forcing us to take possible violent measures in carrying out our mission—or by helping us do it quietly and thus saving a great number of lives?"

"Think of the weapons we have," Vannevan said. "Think how your Earthmen are armed. You know how much chance they have of fighting us off."

Birrel thought they would have a very good chance, but he didn't say so. He frowned, and looked uneasily at the floor.

"What would you want me to do?"

"Vannevan tells me that your people are in possession of a certain probe-ray record that was taken from our man. We'd want that back."

"That's impossible," Birrel said. "The President himself couldn't get at it."

Wolt shrugged. "In that case, you would have to supply us with similar information."

There was a long silence. Then Birrel said, with just the right lack of conviction,

"No, I can't do it."

Vannevan stood up. "I think we'd better show him the cavern, Wolt. I don't believe he understands yet just how much the safety of Earth depends on him."

Wolt nodded. He rose, too, and walked to the wall. It appeared perfectly blank and solid, but under the pressure of his hand a segment of it swung in, revealing a tiny lift. The three men got in, the door closed, and the lift plunged down.

Birrel tried to keep his excitement well hidden. His act was already paying off—apparently they were about to show him something that even the Ruunites didn't know about.

Just how he might use that knowledge to help himself and his two friends he could not figure yet. But his stretch in the OSS had taught him well. Keep your mind alert and flexible, play it by ear, and wait for the break which may come in a hundred ways and from the most unexpected sources.

The lift let them out onto a narrow platform beside a car that ran from a track through a tunnel hollowed roughly out of bedrock underneath the city. They got into it and the car shot through stale darkness relieved by a few dim lights. It went fast.

Birrel stole a glance at the other two men, and decided against any precipitate action. Vannevan had something hidden in his hand, and it would be something small and nastily potent as a weapon, he was sure. He'd wait, play it along—

There was light again, sudden and bright. The car burst into it, into vast and unexpected space. For a second Birrel thought they had come back to the surface again. Then he saw the rocky vault high overhead and the walls going away on either side and he knew it was a mammoth cavern.

The car stopped. They stepped out onto a platform.

"This way," said Wolt. "I want you to see it all."

They moved off the platform and onto a railed shelf cut out of the rocky wall. And Birrel stared in amazement.

The end of the tunnel and the shelf on which they stood were about halfway up the cavern wall. Below, and stretching away as far as he could see, rank upon rank of great metal shapes stood, some painted in dour red or gray, others naked, gleaming steel or copper. There was no one in the cavern, no sound, no movement—nothing but the brooding silence and the loom of the endless rows of enigmatic mechanisms.

Wolt and Vannevan looked down on them, with the faces of men who see a beautiful and splendid vision. And Wolt said,

"Do you know what those are?"

Birrel said, "No."

"And how should you? Your world is still in the nursery. Those are weapons—or they will be, when they are mounted in ships. Mighty weapons, that lack just one thing—the fissionable matter that must power them. The matter that our world doesn't have. Perhaps you understand now why we must raid your atomic stockpiles?"

"But," said Birrel, staring wide-eyed at the terrifying array of giants below him, "where are your ships? You'd need hundreds—"

"We have them," Vannevan said. "All we need to put at end to the domination of Ruun forever."

He turned to Birrel with an expression of serious and friendly candor that might have fooled him if he not known Vannevan so well.

"We have no interest whatsoever in Earth as a conquest. But don't overlook the fact that now the Ruunites know how rich your planet is. They might decide to take it over, just as they've taken over every world in this system but Ir. So in helping us break Ruun's power, you're actually protecting your own world. Now what do you say?"

Birrel looked out over the silent cavern with the endless ranks of deadly machines. He pretended to be miserable, torn between doubt and longing. Finally he said,

"I've got to think it over. Give me time—"

Wolt started to speak, but Vannevan shot him a look and said easily, "Of course, take all the time you want. There will be several days before the ships are ready."

"Ships?"

"Going to Earth. I'll be going with them, of course, to lead the raid. Or I should say, ahead of them. They'll wait in space until they get my signal. You could come back with me, if you decide to help."

Again, on a note of desperation, Birrel said, "I've got to think."

They took him back to the car and through the tunnel and into the building again. There guards took him upstairs and placed him in a small square room without even slits in the wall, furnished with a bed, a table, and a chair. They locked the door and left him alone there, with nothing to do and nothing to see, and nothing even to hear but the soft blowing of air through an iron-barred duct in the ceiling.

Maximum security, and no distractions. In this place a man couldn't do anything but think.

Food was brought. The guard who brought it admitted it was now night outside, but he refused to say anything about Kara and Thile, where they were or if they were still alive.

Birrel ate. A little after that the lights went off. He groped his way to the bed and lay down, trying to see a way out, a way to help Thile and Kara and stop the evil that was about to be done, and seeing only darkness.

Eventually, without meaning to, he fell asleep.

He was wakened by a sound. It was a very slight sound, and it took him a minute to identify it as the clink and creak of an iron grating being moved. By that time it was too late.

Somebody was already in the dark room, and before Birrel could call out a man's body was on top of him and strong hands were fastening on his throat.

CHAPTER IX

Birrel had been close to death before, but never closer. Those hands clamped down, shutting off voice and breath, and the weight of a powerful body bore on him, holding him. He heard quick harsh breathing, and then the booming of his own blood in his ears drowned it out. He clawed at the wrists that would not be moved, and felt the first cold edge of darkness sliding over him.

Then memory circuits clicked over—circuits long unused, but needing only the right stimulus to activate them.

Birrel put his two clenched fists together and rammed them upward with the desperate strength of an animal that knows it has to shake itself loose or die. The fists hit something and there was a noise in the dark above him. The hands on his throat loosened a little and he thrashed his arms up and back at the same time he got what purchase he could with his feet and heaved.

The hands let go. The body floundered on him, not wanting to be thrown off. He pounded at it, wildly, viciously, gasping air into his lungs. He felt hair under his fingers. He grabbed a fistful of it and hauled it sideways. Someone whimpered and cursed, not making much noise about it. He hauled and heaved and the body rolled off him and thumped onto the floor. Instantly, Birrel threw himself on top of it.

And now it was his turn.

He dug his knee into a yielding belly and heard the breath go out. Fists flailed at his face but he kept his head pulled in between his hunched-up shoulders. He pawed in the dark and found an ear, and then another one, and he held onto them like handles and beat the skull between them up and down on the floor.

"Who is it?" he snarled. "Vannevan? No, he doesn't like his odds this even. But he sent you, didn't he?"

A hoarse, half-articulate "No!" came from the man pinned beneath him.

Birrel paused. "The devil he didn't."

"The devil he did. I'd kill that murdering bastard too, if I could get my hands on him." The man squirmed and sobbed for breath. "Anyway, why would Vannevan want to kill you? You're going to help him."

"How do you know?" asked Birrel, his eyes narrowing in the dark.

"The whole underground knows it. You're helping him get fissionables from your world. Why do you think I'm here? To keep you from doing it!"

He erupted into sudden action, catching Birrel off guard as he grappled with this new concept of an Irrian underground opposed to Vannevan. It wasn't too surprising, remembering those sullen faces in the streets. But then they were rolling over, clawing and pounding at each other. Now, though, Birrel's movements were chiefly defensive.

"Hold it," he panted. "Hold it! I've got an idea that we're on the same side."

The man laughed hoarsely and went on hunting for his throat.

"All right," said Birrel. "We'll play it your way."

He gave the man a slashing blow with the edge of his hand, guessing at the distance. It hit a little low on the shoulder, but it jarred him enough to slow him down. Birrel moved quickly. In a second he had his forearm under the man's chin, in a strangle-hold. He applied pressure, and the man became quiet.

He let up. "Now will you listen?"

The man whispered, "Yes."

"There's an underground movement here, against Vannevan and Wolt and the other oligarchs?"

"Against war. We're sick of it. You must have seen what it's done to our world. So we organized ourselves when this plan to steal fissionables from another solar system came up." He struggled against Birrel's grip. "Today we heard Vannevan had brought back an Earthman who was going to help—"

"Relax," said Birrel. "I'm not going to help Vannevan do anything." He explained rapidly. "I was stalling for time, waiting for a chance to make a break. Get me out of here, and I'll prove it."

The man remained unconvinced.

Impatiently, Birrel hauled him to his feet. "Two friends of mine, Ruunites, are somewhere in this building. If you could get to me, you can get to them. I want them freed. And I want to talk to the leaders of your underground. Between us I think we might have a chance to stop Vannevan and his party for good. Anyway, what have you got to lose? If your people have me, I can't help Vannevan."

The man said, grudgingly, "Well, all right. I can get to your friends if you really want them freed. I helped build this place." He stepped away from Birrel, rubbing his throat. "Take off your shoes and any metal you have on you."

Birrel did as he was told.

"Now reach up toward the grating. You'll find a knotted rope. Be as quiet as you can."

Birrel climbed the rope, to a place where the duct became level enough to crawl in. He heard the man replace the grating behind them. Then he joined him, and they began a slow mole-like journey through the maze of air-ducts that supplied these inner cells of the Ministry's private prison.

The man found his way quite easily. At every intersection of the ducts luminous code-numbers glowed—"To help us when we make repairs," the man whispered, and laughed. "We use the ducts all the time for spying. I suppose tonight will finish their usefulness, but we'll find some other way."

The underground had known where Thile and Kara were prisoned almost as soon as they had been put there. Twice the knotted rope was let down and twice gratings were removed and then replaced. Birrel went down after Kara himself and took a second or two to hold her in his arms before he lifted her into the duct.

Some time later, he had no idea how long, they had worked their way down below the level of the building and into a dry conduit that their guide said was left over from an earlier day, before the city was rebuilt. The conduit took them for some distance, and then they climbed a flight of wooden stairs into a cellar, and from there went up into the main room of a modest house, where half a dozen active and hard-faced men sat waiting.

They sprang up when Birrel and the others came in, two or three of them pulling weapons. There was a period of heated conversation, and then one of the men shouted for order and got it.

"Now then," he said, "let's hear about it. You first."

He listened, and the others listened, and all the time they watched Birrel with hatred and distrust.

Impatiently, before the man was through telling why he had not killed the Earthman, Birrel broke in on him to speak to Thile and Kara.

"They showed me something today," he said. "Vannevan and Wolt. A cavern full of armaments—enough to blow Ruun out of the sky as soon as they get the fissionable material they need."

Thile said, "We had an idea there was such a place, but we could never pin it down."

"Neither could we," said the man who seemed to be the leader of the group. He looked hard at Birrel. "It's a mighty well-kept secret."

"There's a direct way into it from Wolt's office," Birrel said, and described it. "Now listen. If we can get away, get word to Ruun—"

"If you're thinking of ships, it's impossible. They're too well guarded on the ground, and the batteries would blow you apart before you could clear the atmosphere."

"Well, then," said Birrel, "is there any way to send a message? Can you communicate from world to world?"

"Quite easily," said Thile. "But there it comes down to the same old thing. Proof."

"For God's sake," said Birrel, "how much proof do they need?"

"Quite a bit, to get them to act in time. I assume that's what you have in mind, isn't it? Blast the cavern and destroy the armaments?"

"I want to stop that fleet from taking off for Earth. If he hasn't any way to use fissionable matter, Vannevan may not be in such a rush to get it."

The other men were listening now with intense interest. They seemed to have forgotten a lot of their distrust in the excitement of learning about the cavern. The leader, who said his name was Shannock, said fiercely,

"Those armaments have taken years of work and a fortune in money, taxed out of our pockets. They've kept us poor, when we might have been building up trade and business on a peaceful world. If they were wiped out, the war party would go with them."

Thile said wistfully, "It's a beautiful thought. But by the time our cautious leaders on Ruun have assured themselves that they're not making a mistake, it'll be far too late."

"There must be some way," Birrel said, striding around in an agony of frustration. "Some way. Some—listen, can you transmit visually, from world to world? Could you send a picture to Ruun?"

"Of course," said Shannock, rather shocked at his ignorance. "The interplanetary automatic relay system has been working ever since we learned how to build spaceships."

Then a queer look came over his face.

"You mean to transmit right from the cavern?"

"That would be proof enough, wouldn't it?" Birrel demanded. "If we showed them the actual cavern, down to the actual armaments?"

Looking a little stunned, Thile said it ought to be proof enough for anyone. "There's just one question. How are you going to do it?"

"Technically, can it really be done?"

"With a special type of transmitter, yes."

Birrel looked at the men of the underground. "If you'll help, we ought to be able to make a pretty good try. How many men can you muster in a hurry—armed?"

"About twenty," Shannock said. "Besides us."

"And can you get portable equipments?"

"Easy. We can get into the Ministry building, too, by a way we know. But from then on we'll have to fight. Likely some of us won't make it."

"Likely," Birrel admitted, thinking privately that probably none of them would make it all the way. "But since we're all due for the gallows one way or another, this looks like our only chance to make Wolt and Vannevan sweat. Want to try it?"

"Give me half an hour," said Shannock. His eyes blazed with a feral light.

Birrel waited. It was a little less than a half hour and it seemed like no time at all because he spent it talking to Kara, and the things he wanted to say to her would have taken hours. Perhaps years. When finally, armed now and accompanied by twenty-seven determined men of the underground, he and Thile started back through the conduit, Kara went with them. There was no safe place to leave her, and in any case Kara was a soldier, share and share alike. She carried a weapon and walked beside Birrel, and after a while it didn't seem strange to him that she should do so, but rather as it should be.

This time they did not enter the duct system. They came through a drainage pit into an unused cellar, and from there directly into the main hall of the Ministry.

It was past midnight and the building was quiet. The guards stood at their posts, but the eruption of armed men into the hall came so suddenly that they had only time for a few scattered shots before they were dropped. Shouts and sounds of alarm and running feet came from other parts of the building. Leaving one man on the floor of the hall, the attacking party rushed into Wolt's office and barred the door.

"Hold it," Birrel panted, "while I find the right stone."

He pawed frantically at the wall, trying to remember exactly where Wolt had placed his hand. Outside there was a tramping of feet and a growing clamor of voices. "Can't you find it?" Thile said.

Shannock ordered his men back from the door. They grouped themselves behind Birrel with the men who carried the portable transmitter in their center. "You better find it," Shannock said, "or—"

His words were drowned in a roaring crash as the door was blown in. Weapons began to hiss and whine. "Hold them, hold them," Birrel begged. "Here it is—"

The stone shifted under his fingers. The concealed door swung open. Birrel pushed Kara through it and then the men with the transmitter. They packed into the small lift and shot down, still firing as the automatic door slammed shut. They had lost four more in the office.

"There's no guard in the cavern itself, they didn't want too many knowing about it," Birrel said. "But they'll soon be after us from this end."

They wrecked the lift door as well as they could, hoping to cripple it, and then loaded themselves into the car and raced away down the dark tunnel.

"They'll come after us, yes, but it'll take them a little time to walk," said Shannock.

The car rushed out of the dark and into the cavern, stopping by the lighted platform. And in this great space of looming, silent, ugly metal shapes, their voices and the noises they made seemed loud.

Shannock rattled out orders. "Set up your transmitter on the shelf here. Wreck that car. Then we'd better split our forces. Half here to hold the tunnel, half down below in case they come in by some other way."

Thile and Kara stayed with the technicians. They were going to have to do the talking. Birrel stayed at the tunnel mouth, with Shannock's lieutenant and half the men. Shannock and the rest of the men climbed down a spiral steel stair that dropped dizzily from the shelf to the cavern floor.

They had collected extra weapons from their own fallen and from guards they had killed in the building, and with these they crouched down behind the barrier of the wrecked car.

Birrel watched the technicians out on the shelf. He had gathered that they had ways of surmounting what would have been insurmountable difficulties on Earth, using types of impulses and rectifiers and carrier-beams unknown there. The equipment did not particularly resemble television equipment as he knew it. Anyway, the technicians seemed to know what they were doing. He hoped they did. It would be a pity to go to all this trouble for nothing.

He saw Thile, and then Kara, making animated gestures as they talked into the transmitter. They were, apparently, going to have time at least to get the message on its way. Then, with terrifying unexpectedness, the voice of God seemed to speak from the air, deafening them.

"Lay down your arms!" it said. "Surrender—you are surrounded on all sides—"

"Amplifiers," said Birrel. "They must have needed them to order things done, in a place this size. Look out, now. They'll rush us any minute—"

And they did, coming out of the dark tunnel in a fury of flashing beams from their weapons.

From behind the wrecked car someone threw an energy-grenade and then another. The results were a little too good. The whole roof of the tunnel fell in, effectively blocking it to the enemy, but also sealing off any possibility of fighting their way back out through it.

Birrel looked around. Thile and Kara and the technicians were still sticking to their task. Down below, on the cavern floor, Shannock had driven back an attack, but from up here Birrel could see the men hiding among the looming machines and knew how badly Shannock was outnumbered.

He flung himself down the spiral stair, and the others followed. The loudspeakers roared monotonously overhead, ordering them to surrender. Birrel took up a position behind a huge looming metal bulk and then looked up at the shelf. Thile, Kara and the technicians had disappeared. A second later he saw them coming at breakneck speed down the stair, and in almost the same second something exploded with a blinding flash on the shelf and the transmitter vanished.

"Surrender," said the amplifiers. "We will grant you a fair trial if you do, but if you do not you will be killed to the last one. Surrender—"

Thile and Kara joined Birrel behind his metal bulwark, panting.

"Did you get through?" he cried.

"We don't know. There wasn't time to receive acknowledgement."

"Here they come!" yelled Shannock.

And they came, slipping among the looming shapes of potential destruction, firing, killing, being killed, being for the second time driven back.

And now for a moment the amplifiers fell silent and another voice spoke close at hand. Vannevan's voice.

"Count your dead. You can't replace them, but we can. How long can you hold out?"

"As long as there's one of us left!" Shannock shouted back.

"That won't be long, will it? Don't be a fool, man. Surrender."

Birrel answered him. "You'll be the one to surrender, when the ships come from Ruun."

Vannevan laughed. "The Earthman. You still think the Ruunites will fight, eh? They won't."

They attacked again, and were again fought off—or rather, Birrel thought, they withdrew, content to hack away at their opponents' numbers without exposing themselves any more than they had to.

The amplifiers spoke again. But suddenly the voice had a different tone, and it did not talk about surrender.

"A message has just been received from Ruun. Ruunite ships will position over this target in one hour and destroy it. All persons are warned to get clear of the area at once. I repeat that message. Ruunite ships will position—"

Pandemonium broke out in the rebel ranks.

"You hear that, Vannevan?" Birrel shouted. "You're through."

Vannevan did not answer.

The amplifiers fell silent. Birrel looked at Thile, and then at Shannock, who said,

"They're not going away."

"Vannevan," said the amplifiers, "this is Wolt. I am leaving as of now and I advise you to do so. There's no virtue like knowing when it's time to run."

Still there was no sound or sign from Vannevan.

The amplifiers were silent. In the distance were noises made by people going away.

One of the men, impatient, sprang up and into the open aisle between the machines. "Hell," he said, "they must have gone. We'd better—"

He died between words, and suddenly from where they had crept close seven or eight men sprang out and rushed, firing. Vannevan led them. There would be no peace, no surrender, no flight for Vannevan.

He saw Birrel with Thile and Kara and he smiled and flung his weapon up, and Birrel shot him just before his finger touched the firing-stud.

Those of the seven or eight who were still alive threw their weapons down.

Shannock said, "I guess we can go now."

They followed the captive soldiers to the far entrance of the cavern, leaving Vannevan where he had fallen among the machines.

An hour later, Birrel stood with the others in the forefront of a close-packed crowd outside the city, and watched the great Ruunite ships position over a particular spot. Mighty lightnings crashed downward from their bellies. Smoke and dust and shattered rock rose in a vast cloud, and settled again, and there was a huge gaping hole in the ground, and still the lightnings pounded at it until there was nothing left of the cavern or anything it had contained.

Shannock and his men cheered mightily. The bulk of the Irrian crowd watched silently, not used yet to the idea of peace.

Birrel, oddly enough, was not thinking of Ruun or Ir, but of Earth.

CHAPTER X

The ship swept in toward the night side of Earth in a great curve, and first of all Earthmen that had ever lived, Birrel felt the sharp, nostalgic emotion of coming back to the world that would always be "the" world.

He was in the bridge with Thile and Kara. Kara was very silent, looking at the shadowed planet-face ahead, not looking at Birrel at all. But Thile was busy, and vocal about it.

"It's hard enough to make a landing on a strange planet," he said. "But to have to do it secretly, without being seen—well, I'm glad this will be the last time."

The last time, Birrel thought. The last ship that would come from the stars to Earth—at least, for a long, long time. He didn't like that thought. He had argued against it, back there at the other system, at Ruun.

The men who governed Ruun were wise and well-meaning men—but obstinate. They had welcomed Birrel. They had been grateful to him. They had agreed to return him to his own world. But on one thing, they were adamant. There would be no sudden opening up of the starways, no open contact between Ruun and Earth.

Birrel, his head full of visions of a sudden leap into the stars by the men of Earth, had pleaded. But in vain.

"Your world Earth is not ready," had said the leader of the Council of Ruun. "It is not even one world, yet. When it has become one—when it has forgotten the folly of wars and weapons—then we will not need to come to you. You will come to us."

He had softened that final refusal by an offer. "But you, who have done much for us, can stay here at Ruun if you wish."

"I can't," Birrel had said heavily. "I'm an agent, with a mission. If I didn't go back, those who sent me would never know what happened—they'd live in perpetual apprehension of attack from outside. I have to return with my report."

"Then you will be taken. And after that, no more of our ships will go there."

And now this last ship from outside was quietly coming down toward the nighted face of Earth, and Kara still was silent, and there was a sickness in Birrel's heart.

Thile, by the control-panel, told the helmsman, "Now softly, softly, are you trying to wake the whole damned continent?—softly—ah!"

They had landed.

Thile and Kara went down the ladder in the darkness, with Birrel. They stood with him by the loom of the ship.

The tall trees around them were black and vague, but the smell of pine was on the keen air, and the smells, the sounds, the feel of everything was subtly right again.

"We landed a lot farther south than last time, so you can soon find a road and people," said Thile. "Well, lad—"

He shook hands with Birrel, and then he turned and shook hands with Kara, and kissed her, and said, "You're a bloody fool but I'd do the same thing," and turned and started back up the ladder.

Birrel said, finally, "Kara—"

"Yes," she said. "I'm staying."

He took her in his arms and could only speak her name again, and then she said, "We have to stand clear, before the ship takes off."

"I can't let you do this!" he cried. "It's why I wouldn't ask you to do it. No ship will come again, and you'll weary of it here, and—"

"Yes, yes," she said, as one might quiet a troubled child, "I know all that. But right now, we must get clear of the ship."

Minutes later, from a ridge a thousand yards away, they heard a boom of thunder and saw a quickly-muffled blast of flame, and then glimpsed the great silver bulk riding skyward, vanishing almost at once.

Birrel, holding Kara, looked up with her into the starry sky and saw the flying shadow against the stars, that was there for an instant and then was not there at all.

He wondered if, in the years ahead, she would look more and more with memory and longing at that starry sky. He hoped, he prayed, that she would not.

Royalty payments must be paid within 60 days following each date on which you prepare (or are legally required to prepare) your periodic tax returns. Royalty payments should be clearly marked as such and sent to the Project Gutenberg Literary Archive Foundation at the address specified in Section 4, “Information about donations to the Project Gutenberg Literary Archive Foundation.”

If you wish to charge a fee or distribute a Project Gutenberg™ electronic work or group of works on different terms than are set forth in this agreement, you must obtain permission in writing from the Project Gutenberg Literary Archive Foundation, the manager of the Project Gutenberg™ trademark. Contact the Foundation as set forth in Section 3 below.

1.F.

1.F.1. Project Gutenberg volunteers and employees expend considerable effort to identify, do copyright research on, transcribe and proofread works not protected by U.S. copyright law in creating the Project Gutenberg™ collection. Despite these efforts, Project Gutenberg™ electronic works, and the medium on which they may be stored, may contain “Defects,” such as, but not limited to, incomplete, inaccurate or corrupt data, transcription errors, a copyright or other intellectual property infringement, a defective or damaged disk or other medium, a computer virus, or computer codes that damage or cannot be read by your equipment.

1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for the “Right of Replacement or Refund” described in paragraph 1.F.3, the Project Gutenberg Literary Archive Foundation, the owner of the Project Gutenberg™ trademark, and any other party distributing a Project Gutenberg™ electronic work under this agreement, disclaim all liability to you for damages, costs and expenses, including legal fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR NEGLIGENCE, STRICT LIABILITY, BREACH OF WARRANTY OR BREACH OF CONTRACT EXCEPT THOSE PROVIDED IN PARAGRAPH 1.F.3. YOU AGREE THAT THE FOUNDATION, THE TRADEMARK OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL NOT BE LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT, CONSEQUENTIAL, PUNITIVE OR INCIDENTAL DAMAGES EVEN IF YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH DAMAGE.

LIMITED RIGHT OF REPLACEMENT OR REFUND - If you discover a defect in this electronic work within 90 days of receiving it, you can receive a refund of the money (if any) you paid for it by sending a written explanation to the person you received the work from. If you received the work on a physical medium, you must return the medium with your written explanation. The person or entity that provided you with the defective work may elect to provide a replacement copy in lieu of a refund. If you received the work electronically, the person or entity providing it to you may choose to give you a second opportunity to receive the work electronically in lieu of a refund. If the second copy is also defective, you may demand a refund in writing without further opportunities to fix the problem.

1.F.4. Except for the limited right of replacement or refund set forth in paragraph 1.F.3, this work is provided to you ‘AS-IS’, WITH NO OTHER WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY OR FITNESS FOR ANY PURPOSE.

1.F.5. Some states do not allow disclaimers of certain implied warranties or the exclusion or limitation of certain types of damages. If any disclaimer or limitation set forth in this agreement violates the law of the state applicable to this agreement, the agreement shall be interpreted to make the maximum disclaimer or limitation permitted by the applicable state law. The invalidity or unenforceability of any provision of this agreement shall not void the remaining provisions.

1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation, the trademark owner, any agent or employee of the Foundation, anyone providing copies of Project Gutenberg™ electronic works in accordance with this agreement, and any volunteers associated with the production, promotion and distribution of Project Gutenberg™ electronic works, harmless from all liability, costs and expenses, including legal fees, that arise directly or indirectly from any of the following which you do or cause to occur: (a) distribution of this or any Project Gutenberg work, (b) alteration, modification, or additions or deletions to any Project Gutenberg work, and (c) any Defect you cause.

Section 2. Information about the Mission of Project Gutenberg

Project Gutenberg is synonymous with the free distribution of electronic works in formats readable by the widest variety of computers including obsolete, old, middle-aged and new computers. It exists because of the efforts of hundreds of volunteers and donations from people in all walks of life.

Volunteers and financial support to provide volunteers with the assistance they need are critical to reaching Project Gutenberg’s goals and ensuring that the Project Gutenberg collection will remain freely available for generations to come. In 2001, the Project Gutenberg Literary Archive Foundation was created to provide a secure and permanent future for Project Gutenberg and future generations. To learn more about the Project Gutenberg Literary Archive Foundation and how your efforts and donations can help, see Sections 3 and 4 and the Foundation information page at www.gutenberg.org.

Section 4. Information about Donations to the Project Gutenberg Literary Archive Foundation

Project Gutenberg™ depends upon and cannot survive without widespread public support and donations to carry out its mission of increasing the number of public domain and licensed works that can be freely distributed in machine-readable form accessible by the widest array of equipment including outdated equipment. Many small donations ($1 to $5,000) are particularly important to maintaining tax exempt status with the IRS.

The Foundation is committed to complying with the laws regulating charities and charitable donations in all 50 states of the United States. Compliance requirements are not uniform and it takes a considerable effort, much paperwork and many fees to meet and keep up with these requirements. We do not solicit donations in locations where we have not received written confirmation of compliance. To SEND DONATIONS or determine the status of compliance for any particular state visit www.gutenberg.org/donate.

While we cannot and do not solicit contributions from states where we have not met the solicitation requirements, we know of no prohibition against accepting unsolicited donations from donors in such states who approach us with offers to donate.

International donations are gratefully accepted, but we cannot make any statements concerning tax treatment of donations received from outside the United States. U.S. laws alone swamp our small staff.

Please check the Project Gutenberg web pages for current donation methods and addresses. Donations are accepted in a number of other ways including checks, online payments and credit card donations. To donate, please visit: www.gutenberg.org/donate.

Section 5. General Information About Project Gutenberg electronic works

Professor Michael S. Hart was the originator of the Project Gutenberg concept of a library of electronic works that could be freely shared with anyone. For forty years, he produced and distributed Project Gutenberg eBooks with only a loose network of volunteer support.

Project Gutenberg eBooks are often created from several printed editions, all of which are confirmed as not protected by copyright in the U.S. unless a copyright notice is included. Thus, we do not necessarily keep eBooks in compliance with any particular paper edition.

Most people start at our website which has the main PG search facility: www.gutenberg.org.

This website includes information about Project Gutenberg, including how to make donations to the Project Gutenberg Literary Archive Foundation, how to help produce our new eBooks, and how to subscribe to our email newsletter to hear about new eBooks.
