Then Wes Kirk revealed the secret to his meant the death of the girl he loved. Wes Kirk shut his teeth together, hard. He turned his back on Ma Kirk 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 His voice carried inside on the wind eddies. Ma Kirk yelled, "Who's to hear it?" Kirk raised his heavy overlids and let his pupils Between the fields and the gullies there were huts like his own, sunk into the earth and sodded tight. A lot of huts, but not as many as 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 where the huts had been, the tumbled heaps of metal that might have The baby cried. Ma Kirk shrilled at her son, and two of the younger Kirk's voice was soft in his thick throat. "I would like to kill them," "Yah!" cried a shrill voice over his shoulder. "All but the Captain's Kirk spun angrily around. Lil, next below himself, danced back out of She squatted demurely beside Ma Kirk and said, as though nothing had 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 kill them—all but the Captain's yellow daughter?" Kirk's big heavy chest swelled. "Ma," he said, "you make that brat shut Ma Kirk looked at him. "Your Pa's still big enough to whale you, young "All right," said Kirk sullenly. He squatted down, holding his hands "Maybe," said Kirk heavily, "it all goes to the same place." there, awesome and accusing. Ma Kirk's eyes flicked to the curtain over Kirk snorted. "You women know so much. If they let the shags or the Officers want us killed off anyhow?" 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 "Yeah," said Kirk. "I'll watch out for him." Kirk shivered in the cold wind. "Lil," he said. "I would, too, kill the There was no conviction in her voice. The wind was freezing on Kirk's 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 bitter force, always probing. He wasn't much older than Kirk. Kirk looked up the hill. Officers were running from the huts below the gaunt, dead Ship. They didn't look so different from the Hans, only 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 them in splinters. Kirk said fiercely: Kirk looked up. Someone was standing at the doorway of the Captain's 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 It looked to Kirk as though the pillbox was pretty far gone. 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 Pa hadn't been alone, of course. Frank and Russ went with him. The Kirk's nose wrinkled at the smell of blood. He avoided the biggest Kirk grunted. A Pirut with red hair standing straight in the wind came over the wall. Kirk speared him left-handed in the belly, dodged the downstroke of his loaded sap, and kicked the body out of the way. The Piruts began to slack off. Stones still whistled past Kirk's He stopped. Kirk put a stone accurately through the back of a Pirut's Randl whispered, "Wes. Wes!" He held up one thin hand. Kirk let his own joined the shoulder. Kirk could see the bright blood beating up through "It's up to you, Wes. You're the only one that really knows about the Ship. You'll do better than I would, anyhow. You're a fighter. You carry it on, so the Hans can live. Promise." Kirk nodded. He couldn't say anything. The heat was dying in Randl's eyes. Kirk bent. He didn't move for a long time. After a while Randl's voice Randl's hands slid away, so that Kirk could see the hole the stone had Presently someone came up and shook Kirk's shoulder and said, "Hey, Kirk laid the body carefully on the stones and got up. "Yeah." 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. That ladder made Kirk think of Pa. It was the only way for a man to get "I'm Wes Kirk, sir. You wanted me?" "Yes." The O.D. was also the Third Officer. Taller than Kirk, thinner, Kirk knew. The knowledge leaped through him. It was strange, to feel a He said, "Pa." The Officer nodded. He seemed very tired, and he didn't look at Kirk. "Kirk," he said, "this is going to be hard to explain. I've never done "I let them get as close as I dared," said the Officer tonelessly. "I Kirk's voice wasn't a voice at all. "You killed them. You killed my 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." The Officer, the bloody wall, the stars and the cold grey gullies all 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. "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 Pa, and the Ship with the heat-stones in it, and the Captain's yellow "That's mutiny. For God's sake, don't make things worse!" "Worse for us, or for you?" Kirk was shouting, holding his head up in the wind. "Listen, you men! Do you know what the Officers are doing up there in the Ship they won't let us touch?" There was an uneasy stirring among the Hans, a slipping aside of luminous black eyes. The Officer shut his jaw tight. He stepped in close to Kirk. Kirk's eyes were hot and not quite sane. He couldn't have stopped if The Officer hit him on the jaw, carefully and without heat. Kirk sagged down. The Officer stepped back, looking as though he had a pain in him Two of the men nodded and took Kirk away down a flight of stone steps.
