He lighted a cigarette. As soon as she was dead, he would jettison her, crate and all, into space. Then he would get good and drunk. And at last, he would return to Earth a sadder and wiser man. No more substitutes for him! Plain, old-fashioned girls were good enough. Yessir, Garvey told himself, if women were all right for my father, they're all right for me. And when I have a son, I'm going to say to him, son, stick with women. They're all right. Accept no substitutes. Insist upon the genuine article.... He was getting giddy, Garvey noticed. And his cigarette had gone out. He resisted a tremendous desire to giggle, and looked at his gauges. The air was leaving the after cabin, all right. But it was also leaving the control room. Garvey sprang to his feet and inspected the cabin door. He swore angrily. That damned surrogate had managed to spring the hinges. The door was no longer airtight. He turned quickly to the control board and stopped the evacuation of air. Why, he asked himself, did everything have to happen to him? The surrogate renewed her battering tactics. She had picked up a metal chair and was hammering at the hinges. But she couldn't break through a tempered-steel door, Garvey told himself. Oh, no. Not a chance. Never. The door began to bulge ominously. Garvey stood in the center of the control room, sweat rolling down his face, trying desperately to think. He could put on a spacesuit, then evacuate all the air from the ship.... But the spacesuits, together with the rest of his equipment, were in the after cabin. What else? This is serious, Garvey told himself. This is very serious. His mind seemed paralyzed. What could he do? Raise the temperature? Lower it? He didn't know what the surrogate could stand. But he had a suspicion it was more than he could take. One hinge shattered. The door bent, revealing the surrogate behind it, pounding relentlessly, her satiny skin glistening with perspiration. Then Garvey remembered his revolver. He snatched it out of its holster and flipped off the safeties, just as the last hinge cracked and the door flew open. "Stay in there," Garvey said, pointing the revolver. The Algolian substitute moaned, and held out her arms to him. She smiled dazzlingly, seductively, and advanced upon him. "Not another step!" Garvey shrieked, torn between fear and desire. He took aim, wondering if a bullet would stop her.... And what would happen if it didn't. The surrogate, her eyes blazing with passion, leaped for him. Garvey gripped the revolver in both shaking hands and began shooting. The noise was deafening. He fired three times, and the surrogate kept on coming. "Stop!" Garvey screamed. "Please stop!" Slower now, the surrogate advanced. Garvey fired his fourth shot. Limping now, the surrogate came on, her desire unchecked. Garvey backed to the wall. All he wanted now was to live long enough to get his hands on the factory operator. The surrogate gathered herself and pounced.
