<passage>:
The Ship held an ancient secret that meant 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. Wes Kirk shut his teeth together, hard. He turned his back on Ma Kirk and the five younger ones huddled around the box of heat-stones and The hackles rose golden and stiff across Kirk's back. He said carefully, "I would like to kill the Captain and the First Officer and the Second Officer and all the little Officers, and the Engineers, and all their "Who's to hear it?" Kirk raised his heavy overlids and let his pupils Kirk raised his shaggy head. The light of the yellow star they called Kirk's voice was soft in his thick throat. "I would like to kill them," Kirk spun angrily around. Lil, next below himself, danced back out of Kirk didn't say anything. He started to walk around the heat box. Lil Ma Kirk said, "Sit down, or go pick on somebody your own size." Kirk stopped. "Aw, I wasn't going to hurt her. She has to be so smart!" He leaned forward to glare at Lil. "And I would so kill the Captain's daughter!" Officers and the Engineers ever done to you that you should want to kill them—all but the Captain's yellow daughter?" Kirk's big heavy chest swelled. "Ma," he said, "you make that brat shut up or I'll whale her, anyhow." "All right," said Kirk sullenly. He squatted down, holding his hands "It's what everybody says. Why else would they guard the Ship the way Kirk looked at the thin fuzzy baby curled tight in the skins. There was silence in the room again. Kirk felt it, thick and choky. "Listen!" said Ma Kirk. Nerves crackled icily all over Kirk's skin. But there wasn't any need Kirk began to move, very swiftly and quietly. Before the third gong Ma Kirk said stiffly, "Which way are they coming?" Kirk's ears twitched. He sorted the gong sounds, and the wind, and Ma Kirk sucked in her breath. Her voice had no tone in it. "Your Pa went hunting that way." "Yeah," said Kirk. "I'll watch out for him." Men and youths like himself, old enough to fight, were spilling out of low doorways and forming companies on the flat ground. Kirk spotted Jakk Randl and fell in beside him. They stood with their backs to the Randl nudged Kirk's elbow. "Look at 'em," he said, and coughed. He was 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 they were built a little taller and lighter, less bowed and bunchy in the shoulders, quicker on their feet. Kirk stepped behind Randl to shield him from the wind. His voice was had grown louder in Kirk's ears. He could hear men yelling and the He started to run, holding Randl's elbow. Grey dust blew under their feet. The drifts of crystal stones sent their sound shivering back at them in splinters. Kirk said fiercely: Wes." Kirk looked up. Someone was standing at the doorway of the Captain's hut. Someone tall and slender and the color of the Sunstar from head to foot. Kirk's pupils shrank to points no warmer nor softer than the tip of his It was a big raid. Kirk saw that when he scrambled up out of the last any time, but when the Piruts were raiding.... No time to think about that. Wite, the second son of the First Officer, was signalling for double time. Kirk ran faster, his ears twitching furiously as they sifted the flying echoes into some kind of order. Kirk's nose wrinkled at the smell of blood. He avoided the biggest puddles and found a place to stand between the dead. over the wall. Kirk speared him left-handed in the belly, dodged the The Piruts began to slack off. Stones still whistled past Kirk's Randl whispered, "Wes. Wes!" He held up one thin hand. Kirk let his own Kirk nodded. He couldn't say anything. The heat was dying in Randl's "Listen, Wes. I saw the secret way into Ship. Bend closer, and listen...." Kirk bent. He didn't move for a long time. After a while Randl's voice Kirk sat there, holding Randl in his arms. Presently someone came up and shook Kirk's shoulder and said, "Hey, kid, are you deaf? We been yelling for you." He stopped, and then said Kirk laid the body carefully on the stones and got up. "Yeah." "Kind of a pal of yours, wasn't he?" "He wasn't very strong. He needed someone to cover him." better, at that. He was headed for trouble, that one. Kinda leading you that way, too, I heard. Always talking." He looked at Kirk's face and shut up suddenly. He turned away and Kirk followed. The wind was cold, howling up from the outer gullies. The Officer of the Day was waiting at the north end of the wall. some of the queer heaviness out of his head, touched his forelock and said: "I'm Wes Kirk, sir. You wanted me?" "Yes." The O.D. was also the Third Officer. Taller than Kirk, thinner, his horny overlids. He said quietly: "I'm sorry to have to tell you this...." Kirk knew. The knowledge leaped through him. It was strange, to feel a The Officer nodded. He seemed very tired, and he didn't look at Kirk. He hadn't, after the first glance. "Your father, and his two friends." Kirk shivered. The horny lids dropped over his eyes. "I wish I'd known," he whispered. "I'd have killed more of them." "Kirk," he said, "this is going to be hard to explain. I've never done but not far. Not far enough. One of the three, it wasn't your father, called to us to put the ladder down. We waited...." A muscle began to twitch under Kirk's eye. That, too, was something A man came up over the top of the ladder. He was carrying a body over his shoulder, and breathing hard. "Here's Kirk," he said. "Where'll I put him?" Kirk's voice wasn't a voice at all. "You killed them. You killed my father." Kirk's spear made a flat clatter on the stone. He started forward. Men "Please try to understand," whispered the Officer. "I had to do it." Kirk thought of Pa coming up under the wall, close to safety, close enough to touch it, and no way through. Pa and Frank and Russ, standing Kirk relaxed. He was shivering and covered with rime from body sweat. Somebody whistled. "Six men! Didn't know the kid had it in him." The Officer's voice said dully, "No discipline. Better take him home." Kirk tried to turn. The six men swung with him. Kirk said, "You better "I'll understand, all right." Kirk's voice was a hoarse, harsh whisper that came out by itself and wouldn't be stopped. "I'll understand about Pa, and the Ship with the heat-stones in it, and the Captain's yellow close to Kirk. "Shut up," he said urgently. "Don't make me punish you, not now. You're talking rot, but it's dangerous." Kirk's eyes were hot and not quite sane. He couldn't have stopped if while he was dying. The Captain's yellow daughter, sneaking heat-stones into...." The Officer hit him on the jaw, carefully and without heat. Kirk sagged Two of the men nodded and took Kirk away down a flight of stone steps.
