asked incredulously. The older man nodded and picked up his fishbowl helmet. Jeff's face twisted in dismay. "I won't let you!" he half-shouted. "You're risking your life and I can't navigate the ship without you." Helmet in hand, his father paused, the deep-graved lines of his face stiffening. "I'm still master of this ship!" he said curtly. "Alien or not that other ship may need assistance. By intraspace law I'm obliged to give it. If you're worried, cover me from the gun-turret." He dropped the helmet over his head, cutting Jeff off from further protest. Seething with mixed fear and anger, Jeff turned abruptly and climbed hurriedly to the gun-turret. The twin barrels of the rifles were already centered on their target, which the aiming screen showed, together with the area between the two vessels and a portion of the Emerald Girl's airlock, which projected from her side. As Jeff watched, the outer lock swung open and a grey, space-suited figure raced for the protection of the bow. It was a dash of no more than five seconds' duration, but to Jeff it seemed that his father took an eternity to reach safety. He reached for the microphone on the ship's circuit and pulled it to him. "All right, Dad?" In spite of himself, Jeff's voice was still ragged with anger. "Fine, Jeff," his father's voice came back in unperturbed tones. "I'm well shielded and I can get good, clean shots at every part of her." "Let me know when you're ready to start back," said Jeff, and shoved the microphone away from him. He sat back and lit a cigarette, but his eyes continued to watch the other ship as a man might watch a dud bomb which has not yet been disarmed. After a while, he noticed his fingers were shaking, and he laid the cigarette carefully down in the ashtray. When he comes back, thought Jeff, it'll be time. We'll have this thing out then. He's become some sort of a religious fanatic, and he doesn't know it. How a man who's been all over hell and seen the worst sides of fifty different races in as many years can think of them all as lovable human children, I don't know. But, know it or not, this taking of chances has got to stop someplace; and right here is the best place of all. When he gets backāif he gets back, we're taking off. And if he doesn't get back ...
