Lieutenant Brady stood, started toward the captain, stopped. Crowley pushed Dr. Mueller away from him, leaped to his feet and lunged toward the captain. A stream of light appeared between the gun muzzle and Crowley. He stumbled, caught himself, stood up very straight, then sank down, as though he had been deflated. The captain motioned Dr. Mueller to her bunk. She hesitated, pain in her face, turned, went to her bunk and lay down. Another stream of light appeared between her and the gun. She lay very still. The needle slipped from her fingers. The captain turned the gun on Lieutenant Brady, who was coming at him, arms raised. The light beam again. The lieutenant sank back. Caroline Gordon was watching the captain as the light stream appeared. She relaxed, her eyes closed. Daniel Carlyle did not move as the light touched him. Captain McClelland holstered the gun. He picked up the hypodermic needle and sterilized it at the medicine cabinet. Then he injected Crowley's arm, filled the hypo four more times, injected the others. He finally thrust the needle into his own arm and lay down. His breathing began to slow. There was only the control room of the ship now, like some ancient mausoleum, with the six still figures and the control board dark and the eternal ocean of night pressing against the ports. The picture of the ship's control room began to fade on the screen. After a moment of darkness, the live picture of the six old figures, sitting in their half circle, spread again over the lighted square. Colonel Halter saw his own image, looking into the old masks. He said, "And where was _your_ weakness, Captain McClelland?" "I was concerned," said the old voice, "with keeping us alive." "You weren't aware that some of your crew were emotionally involved with each other?" "No." "Are there any more records you could show me?" "Many more, Colonel, but I don't think it's necessary for you to see them. It would take too long. And we want to get back out into space." He paused. "We can brief you." "About your going back into space.... I'm not sure we can allow it." "Our answer's very simple. There's a button, under my thumb, on the arm of this chair. A little pressure. Carbon monoxide. It would be quick." "Your idea?" "Yes. A matter of preserving our integrity. We'd rather die than face the horrors of life on Earth." * * * * * Halter turned to the semi-circle of faces. "And you've all agreed to this--this suicide?" The captain cut in. "Of course. I realized years ago that the only place we could live was in space, in this ship." "When did your crew realize this?" "After a couple of years. I told them over and over again, day after day. After all, I am captain. I dictate the policy." "You've come back. You're in port. You're not in complete command." "I'll always be in command." "Perhaps," said Halter quietly. "However, we can come back to that. Please brief me on the records."
