life to the dying cast-aways of the void. Then Wes Kirk revealed the secret to his people's enemies—and found that his betrayal meant the death of the girl he loved. He shoved the curtain of little skins aside and crouched there with his thick shoulders fitted into the angle of the jamb, staring out, cold wind threading in across his splayed and naked feet. child. She added sharply, "Besides, that's fool's talk, Jakk Randl's talk, and only gets the sucking-plant." "Who's to hear it?" Kirk raised his heavy overlids and let his pupils widen, huge liquid drops spreading black across his eyeballs, sucking the dim grey light into themselves, forcing line and shape out of blurred nothingness. He made no move to drop the curtain. The same landscape he had stared at since he was able to crawl by himself away from the box of heat-stones. Flat grey plain running right and left to the little curve of the horizon. Rocks on it, and guarding their sour white berries with thorns and sacs of poisoned dust that burst when touched. there had been, the old ones said. The Hans died, and the huts were empty, and the wind and the earth took them back again. Kirk raised his shaggy head. The light of the yellow star they called Sun caught in the huge luminous blackness of his eyes. Beyond the Hansquarter, just where the flat plain began to rise, were the Engineers. Not many of them any more. You could see the dusty lumps ones fought over a bone with no meat on it, rolling and snapping on the dirt floor. Kirk shifted his head forward to shut out the sound of them and followed the line of the plain upward with sullen, glowing eyes. reach, her kilt of little skins flying around her thin hips. "Yah!" she said again, and wrinkled her flat nose. "I've seen you looking at her. All yellow from head to foot and beautiful pink lids to her eyes. You wouldn't kill her , I bet!" his arm and jerked the curtain down and shot away again, making two jumps over the brawling young ones and the box of heat-stones. they do? We can't even get near the outside of it." Lil tossed her head. "Well neither do they." "Not when we can see 'em, no. Of course not. But how do we know they plain? Jakk says a lot goes on that we don't know about." a tangle of echoes that came from everywhere at once, but there was no mistaking it. No need even to use sensitive earcups to locate its source. "Yeah," said Kirk. "I'll watch out for him." He glanced back just before he let the curtain drop. The pale glow of the heat-stones picked dots of luminous blackness out of the gloom, where the still breathless faces were, watching him. He saw the blurred shapes of clay cooking pots, of low bed frames, of huddled bodies. The Jakk Randl and fell in beside him. They stood with their backs to the blown straight out. Randl nudged Kirk's elbow. "Look at 'em," he said, and coughed. He was always coughing, jerking his thin sharp face back and forth. Kirk could have broken his brittle light-furred body in two. All Randl's strength was in his eyes. The pupils were always spread, always hot with some bitter force, always probing. He wasn't much older than Kirk. Kirk looked up the hill. Officers were running from the huts below the "Is it true, Jakk? Do you know? Because if they are...." made them blind and deaf. I lay in the rocks and watched. And I saw...." He coughed. The Officers' voices rang sharp through the wind. Compact feet. The drifts of crystal stones sent their sound shivering back at them in splinters. Kirk said fiercely: "What did you see?" hut. Someone tall and slender and the color of the Sunstar from head to foot. the Ship." Kirk's pupils shrank to points no warmer nor softer than the tip of his knife. He smiled, almost gently, looking up the hill. He wondered how so many of them had been able to get so close to the pillbox all at once, walking two or three abreast on the narrow tongue black eyes saw everything. He tried three times to lift his sling and gave it up. He said, "Wonder how they got so close, so fast?" "Some trick." Randl laughed suddenly. "Funny their wanting the Ship as much as you and I do." "Think they could know what's in it?" Randl's narrow shoulders twitched. "Near as we know, their legend is difference is they want to get it for themselves, and we want to keep it." He coughed and spat in sudden angry disgust. "And we've swallowed his fingers. He said, "Jakk, I'll get the sawbones...." Hot black eyes turned to his. Burnt-out fires in a face with the young beard hardly full on its sharp jaw. "Sit down, Wes, quick, and listen. Sawbones is no good—and why would I want to go on living anyway?" He smiled. Kirk had never seen him smile like that, without bitterness or pain. He sat down, crouched on the body of a man who lived only two huts away from him. The blood made little red fountains between Randl's fingers. "It's up to you, Wes. You're the only one that really knows about the eyes. "Listen, Wes. I saw the secret way into Ship. Bend closer, and listen...." more gently, "Oh. Jakk got it, did he?" "Kind of a pal of yours, wasn't he?" "He wasn't very strong. He needed someone to cover him." "Too bad." The man shook his head, and then shrugged. "Maybe it's some of the queer heaviness out of his head, touched his forelock and said: with the hair going grey on his body and exhausted eyes sunk deep under his horny overlids. He said quietly: "I'm sorry to have to tell you this...." He hadn't, after the first glance. "Your father, and his two friends." A muscle began to twitch under Kirk's eye. That, too, was something that had never happened before, like the stab of pain with no spear behind it. He licked his lips and repeated hoarsely: heart.... You saw it.... father." "Three lives, against all those back on the plain. We held our fire Looking up, calling to the men they knew, asking for help and getting a spear through the heart. After that, even the wind was gone, and the darkness had turned red. There was a voice, a long way off. It said, "God, he's strong!" Over and over. It got louder. There were weights on his arms and legs, and Somebody whistled. "Six men! Didn't know the kid had it in him." Pa, and the Ship with the heat-stones in it, and the Captain's yellow daughter getting fat and warm while my sisters freeze and go hungry. I'll understand, and I'll make everybody else understand, too!" The Officer's eyes held a quick fire. "Boy! Do you know what you're saying?" luminous black eyes. The Officer shut his jaw tight. He stepped in close to Kirk. "Shut up," he said urgently. "Don't make me punish you, not now. You're Kirk's eyes were hot and not quite sane. He couldn't have stopped if he'd wanted to. "Rot, is it? Jakk Randl knew. He saw with his own eyes and he told me that he didn't want to show. He said quietly, but so that everyone could hear him, "Discipline, for like a dog. "That Jakk Randl, he was always talking." One of the others flicked a quick look around and whispered, "Yeah. And maybe he knew what he was talking about!"
