"She has no family on Earth," V-Stephens explained. "She came here as a Class-2 biochemist. She's been working over at a Westinghouse lab outside Chicago. She came to New York on a shopping trip, which was a mistake."

  "Can't she join the V-colony at Denver?" Patterson asked.

  V-Stephens flushed. "You don't want another webfoot around here?"

  "What can she do? We're not an embattled fortress. There's no reason why we can't shoot her to Denver in a fast freight rocket. Nobody'll interfere with that."

  "We can discuss it later," V-Stephens said irritably. "We've got more important things to talk about. You've made a check of Unger's papers? You're certain they're not forgeries? I suppose it's possible this is on the level, but we have to be certain."

  "This has to be kept quiet," Patterson said urgently, with a glance at V-Rafia. "Nobody on the outside should be brought in."

  "You mean me?" V-Rafia asked hesitantly. "I guess I better leave."

  "Don't leave," V-Stephens said, grabbing hold of her arm roughly. "Pat­terson, you can't keep this quiet. Unger's probably told it to fifty people; he sits out there on his park bench all day, buttonholing everybody who passes."

  "What is this?" V-Rafia asked curiously.

  "Nothing important," Patterson said warningly.

  "Nothing important?" V-Stephens echoed. "Just a little war. Programs for sale in advance." Across his face a spasm of emotion passed, excitement and yearning hunger pouring up from inside him. "Place your bets now. Don't take chances. Bet on a sure thing, sweetheart. After all, it's history. Isn't that right?" He turned toward Patterson, his expression demanding confirmation. "What do you say? I can't stop it -- you can't stop it. Right?"

  Patterson nodded slowly. "I guess you're right," he said unhappily. And swung with all his strength.

  He caught V-Stephens slightly to one side, as the Venusian scrambled away. V-Stephens' cold-beam came out; he aimed with shaky fingers. Patter­son kicked it from his hands and dragged him to his feet. "It was a mistake, John," he panted. "I shouldn't have showed you Unger's i.d. tube. I shouldn't have let you know."

  "That's right," V-Stephens managed to whisper. His eyes were blank with sorrow as he focused on Patterson. "Now I know. Now we both know. You're going to lose the rear. Even if you lock Unger up in a box and sink him to the center of the Earth, it's too late. Color-Ad will know as soon as I'm out of here."

  "They burned down the Color-Ad office in New York."

  "Then I'll find the one in Chicago. Or Baltimore. I'll fly back to Venus, if I have to. I'm going to spread the good news. It'll be hard and long, but we'll win. And you can't do anything about it."

  "I can kill you," Patterson said. His mind was racing frantically. It wasn't too late. If V-Stephens were contained, and David Unger turned over to the Military --

  "I know what you're thinking," V-Stephens gasped. "If Earth doesn't fight, if you avoid war, you may still have a chance." His green lips twisted savagely. "You think we'd let you avoid war? Not now! Only traitors compro­mise, according to you. Now it's too late!"

  "Only too late," Patterson said, "if you get out of here." His hand groped on the desk and found a steel paper weight. He drew it to him -- and felt the smooth tip of the cold-beam in his ribs.

  "I'm not sure how this thing words," V-Rafia said slowly, "but I guess there's only this one button to press."

  "That's right," V-Stephens said, with relief. "But don't press it yet. I want to talk to him a few minutes more. Maybe he can be brought around to ratio­nality." He pulled himself gratefully out of Patterson's grip and moved back a few paces, exploring his cut lip and broken front teeth. "You brought this on yourself, Vachel."

  "This is insane," Patterson snapped, his eyes on the snout of the cold-beam as it wavered in V-Rafia's uncertain fingers. "You expect us to fight a war we know we're going to lose?"

  "You won't have a choice." V-Stephens' eyes gleamed. "We'll make you fight. When we attack your cities you'll come back at us. It's -- human nature."

  The first blast of the cold-beam missed Patterson. He floundered to one side and grabbed for the girl's slim wrist. His fingers caught air, and then he was down, as the beam hissed again. V-Rafia retreated, eyes wide with fright and dismay, aiming blindly for his rising body. He leaped up, hands extended for the terrified girl. He saw her fingers twist, saw the snout of the tube darken as the field clicked on. And that was all.

  From the kicked-open door, the blue-clad soldiers caught V-Rafia in a crossfire of death. A chill breath mushroomed in Patterson's face. He col­lapsed back, arms up frantically, as the frigid whisper glided past him.

  V-Rafia's trembling body danced briefly, as the cloud of absolute cold glowed around her. Then abruptly she halted as rigid as if the tape-track of her life had stopped in the projector. All color drained from her body. The bizarre imitation of a still-standing human figure stood silently, one arm raised, caught in the act of futile defense.

  Then the frozen pillar burst. The expanded cells ruptured in a shower of crystalline particles that were hurled sickeningly into every part of the office.

  Francis Gannet moved cautiously in behind the troops, red-faced and perspiring. "You're Patterson?" he demanded. He held out his heavy hand, but Patterson didn't take it. "The Military people notified me as a matter of course. Where's this old man?"

  "Somewhere around," Patterson muttered. "Under guard." He turned toward V-Stephens and briefly their eyes met. "You see?" he said huskily. "This is what happens. Is this what you really want?"

  "Come on, Mr. Patterson," Francis Gannet boomed impatiently. "I don't have much time to waste. From your description this sounds like something important."

  "It is," V-Stephens answered calmly. He wiped at the trickle of mouth-blood with his pocket handkerchief. "It's worth the trip from Luna. Take my word for it -- I know."

  The man who sat on Gannet's right was a lieutenant. He gazed in mute awe at the vidscreen. His young, handsome blond face was alive with amazement as from the bank of gray haze a huge battleship lumbered, one reactor smashed, its forward turrets crumpled, hull twisted open.

  "Good God," Lieutenant Nathan West said faintly. "That's the Wind Giant. The biggest battleship we have. Look at it -- it's out of commission. Totally disabled."

  "That will be your ship," Patterson said. "You'll be commander of it in '87 when it's destroyed by the combined Venusian and Martian fleets. David Unger will be serving under you. You'll be killed, but Unger will escape. The few survivors of your ship will watch from Luna as Earth is systematically demolished by C-missiles from Venus and Mars."

  On the screen, the figures leaped and swirled like fish in the bottom of a dirt-saturated tank. A violent maelstrom surged in the center, a vortex of energy that lashed the ships on vast spasms of motion. The silver Earth ships hesitated, then broke. Flashing black Mars battleships swept through the wide breach -- and the Earth flank was turned simultaneously by the waiting Venusians. Together, they caught the remnants of the Earth ships in steel pincers and crunched them out of existence. Brief puffs of light, as the ships winked out of being. In the distance, the solemn blue and green orb that was Earth slowly and majestically revolved.

  Already, it showed ugly pocks. Bomb craters from the C-missiles that had penetrated the defense network.

  LeMarr snapped off the projector and the screen died. "That ends that brain-sequence. All we can get are visual fragments like this, brief instants that left strong impressions on him. We can't get continuity. The next one takes up years later, on one of the artificial satellites."

  The lights came on, and the group of spectators moved stiffly to their feet. Gannet's face was a sickly putty-gray. "Doctor LeMarr, I want to see that shot again. The one of Earth." He gestured helplessly. "You know which one I mean."

  The lights dimmed and again the screen came to life. This time it showed only Earth, a receding orb that fell behind as the high-velocity torpedo on which David Unger rode hurtled toward outer space. U
nger had placed him­self so his dead world would be visible to the last.

  Earth was a ruin. Involuntarily, a gasp rose from the group of watching officers. Nothing lived. Nothing moved. Only dead clouds of radioactive ash billowed aimlessly over the crater-pocked surface. What had been a living planet of three billion people was a charred cinder of ash. Nothing remained but heaps of debris, dispersed and blown dismally across vacant seas by the howling, ceaseless wind.

  "I suppose some kind of vegetable life will take over," Evelyn Cutter said harshly, as the screen faded and the overhead lights returned. She shuddered violently and turned away.

  "Weeds, maybe," LeMarr said. "Dark dry weeds poking up through the slag. Maybe some insects, later on. Bacteria, of course. I suppose in time bacterial action will transform the ash into usable soil. And it'll rain for a billion years."

  "Let's face it," Gannet said. "The webfoots and crows will resettle it. They'll be living here on Earth after we're all dead."

  "Sleeping in our beds?" LeMarr inquired mildly. "Using our bathrooms and sitting rooms and transports?"

  "I don't understand you," Gannet answered impatiently. He waved Pat­terson over. "You're sure nobody knows but we here in this room?"

  "V-Stephens knows," Patterson said. "But he's locked up in the psychotic ward. V-Rafia knew. She's dead."

  Lieutenant West came over to Patterson. "Could we interview him?"

  "Yes, where's Unger?" Gannet demanded. "My staff is eager to meet him face to face."

  "You have all the essential facts," Patterson answered. "You know how the war is going to come out. You know what's going to happen to Earth."

  "What do you suggest?" Gannet asked warily.

  "Avoid the war."

  Gannet shrugged his plump well-fed body. "After all, you can't change history. And this is future history. We have no choice but to go ahead and fight."

  "At least we'll get our share of them," Evelyn Cutter said icily.

  "What are you talking about?" LeMarr stuttered excitedly. "You work in a hospital and you talk like that?"

  The woman's eyes blazed. "You saw what they did to Earth. You saw them cut us to ribbons."

  "We have to stand above this," LeMarr protested. "If we allow ourselves to get dragged into this hate and violence -- " He appealed to Patterson. "Why is V-Stephens locked up? He's no crazier than she is."

  "True," Patterson agreed. "But she's crazy on our side. We don't lock up that kind of lunatic."

  LeMarr moved away from him. "Are you going out and fight, too? Along­side Gannet and his soldiers?"

  "I want to avoid the war," Patterson said dully.

  "Can it be done?" Gannet demanded. An avid glow winked briefly behind his pale, blue eyes and then faded out.

  "Maybe it can be done. Why not? Unger coming back here adds a new element."

  "If the future can be changed," Gannet said slowly, "then maybe we have a choice of various possibilities. If there's two possible futures there may be an infinite number. Each branching off at a different point." A granite mask slid over his face. "We can use Unger's knowledge of the battles."

  "Let me talk to him," Lieutenant West interrupted excitedly. "Maybe we can get a clear idea of the webfoot battle-strategy. He's probably gone over the battles in his mind a thousand times."

  "He'd recognize you," Gannet said. "After all, he served under your com­mand."

  Patterson was deep in thought. "I don't think so," he said to West. "You're a lot older than David Unger."

  West blinked. "What do you mean? He's a broken-down old man and I'm still in my twenties."

  "David Unger is fifteen," Patterson answered. "At this point you're almost twice his age. You're already a commissioned officer on the Lunar policy-level staff. Unger isn't even in the Military Service. He'll volunteer when war breaks out, as a buck private without experience or training. When you're an old man, commanding the Wind Giant, David Unger will be a middle-aged nonentity working one of the gun turrets, a name you won't even know."

  "Then Unger is already alive?" Gannet said, puzzled.

  "Unger is someplace around, waiting to step onto the stage." Patterson filed the thought away for future study; it might have valuable possibilities. "I don't think he'll recognize you, West. He may never even have seen you. The Wind Giant is a big ship."

  West quickly agreed. "Put a bug-system on me, Gannet. So the command staff can have the aud and vid images of what Unger says."

  In the bright mid-morning sunlight, David Unger sat moodily on his park bench, gnarled fingers gripping his aluminum cane, gazing dully at the passers-by.

  To his right a robot gardener worked over the same patch of grass again and again, its metallic eye-lenses intently fastened on the wizened, hunched-over figure of the old man. Down the gravel path a group of loitering men sent random comments to the various monitors scattered through the park, keep­ing the relay system open. A bare-bosomed young woman sunbathing by the pool nodded faintly to a pair of soldiers pacing around the park, within con­stant sight of David Unger.

  That morning there were a hundred people in the park. All were inte­grated elements of the screen surrounding the half-dozing, resentful old man.

  "All right," Patterson said. His car was parked at the edge of the plot of green trees and lawns. "Remember not to overexcite him. V-Stephens revived him originally. If something goes wrong with his heart we can't get V-Stephens to pump him back."

  The blond young lieutenant nodded, straightened his immaculate blue tunic and slid onto the sidewalk. He pushed his helmet back and briskly strode down the gravel path, toward the center of the park. As he approached, the lounging figures moved imperceptibly. One by one they took up positions on the lawns, on the benches, in groups here and there around the pool.

  Lieutenant West stopped at a drinking-fountain and allowed the robot water-brain to find his mouth with a jet of ice-cold spray. He wandered slowly away and stood for a moment, arms loose at his sides, vacantly watching a young woman as she removed her clothes and stretched out languidly on a multi-colored blanket. Her eyes shut, red lips parted, the woman relaxed with a grateful sigh.

  "Let him speak to you first," she said faintly, to the lieutenant standing a few feet from her, one black boot on the edge of a bench. "Don't start the conversation."

  Lieutenant West watched her a moment longer and then continued along the path. A passing heavy-set man said swiftly in his ear. "Not so fast. Take your time and don't appear to hurry."

  "You want to give the impression you have all day," a hatchet-faced nurse greeted, as she passed him wheeling a baby carriage.

  Lieutenant West slowed almost to a halt. He aimlessly kicked a bit of gravel from the path into the wet bushes. Hands deep in his pockets he wan­dered over to the central pool and stood gazing absently into its depths. He lit a cigarette, then bought an ice cream bar from a passing robot salesman.

  "Spill some on your tunic, sir," the robot's speaker instructed faintly. "Swear and start dabbing at it."

  Lieutenant West let the ice cream melt in the warm summer sun. When some had dripped down his wrist onto his starched blue tunic he scowled, dug out his handkerchief, dipped it in the pool, and began clumsily to wipe the ice cream away.

  On his bench, the scar-faced old man watched with his one good eye, gripping his aluminum cane and cackling happily. "Watch out," he wheezed. "Look out there!"

  Lieutenant West glanced up in annoyance.

  "You're dripping more," the old man cackled, and lay back in weak amuse­ment, toothless mouth slack with pleasure.

  Lieutenant West grinned good-naturedly. "I guess so," he admitted. He dropped the melting half-eaten ice cream bar into a disposal slot and finished cleaning his tunic. "Sure is warm," he observed, wandering vaguely over.

  "They do a good job," Unger agreed, nodding his bird-like head. He peered and craned his neck, trying to make out the insignia markings on the young soldier's shoulder. "You with the rocketeers?"

  "Demoli
tion," Lieutenant West said. As of that morning his insignia had been changed. "Ba-3."

  The old man shuddered. He hawked and spat feverishly into the nearby bushes. "That so?" He half-rose, excited and fearful, as the lieutenant started to move away. "Say, you know, I was in the Ba-3 years ago." He tried to make his voice sound calm and casual. "Long before your time."

  Amazement and disbelief slid over Lieutenant West's handsome blond face. "Don't kid me. Only a couple guys from the old group are still alive. You're pulling my leg."

  "I was, I was," Unger wheezed, fumbling with trembling haste at his coat pocket. "Say, look at this. Stop a minute and I'll show you something." Rever­ent and awed, he held out his Crystal Disc. "See? You know what this is?"

  It Lieutenant West gazed down at the metal a long time. Real emotion welled up inside him; he didn't have to counterfeit it. "Can I examine it?" he asked finally.

  Unger hesitated. "Sure," he said. "Take it."

  "That's right," Unger said. "You remember?" He returned it to his pocket. "No, you weren't even alive, then. But you heard about it, haven't you?"

  "Yes," West said. "I've heard about it many times."

  "And you haven't forgotten? A lot of people forgot that, what we did there."

  "I guess we took a beating that day," West said. He sat down slowly on the bench beside the old man. "That was a bad day for Earth."

  "We lost," Unger agreed. "Only a few of us got out of there. I got to Luna. I saw Earth go, piece by piece, until there was nothing left. It broke my heart. I cried until I lay like a dead thing. We were all weeping, soldiers, workmen, standing there helpless. And then they turned their missiles on us."

  The lieutenant licked his dry lips. "Your Commander didn't get out, did he?"

  "Nathan West died on his ship," Unger said. "He was the finest com­mander in the line. They didn't give him the Wind Giant for nothing." His ancient, withered features dimmed in recollection. "There'll never be another man like West. I saw him, once. Big stern-faced man, wide-shoul­dered. A giant himself. He was a great old man. Nobody could have done better."
