"So that's the way it is," Garvey said briskly. "You stay right here, old girl. I'm going to the control room. We'll land on Earth in a few hours. Then I'll arrange to have you shipped to Algol. The boys'll really go for you on Algol! Sounds good, huh?"

The surrogate gave no sign of understanding. Garvey moved away. The surrogate pushed back her long hair and began to move toward him. Her intentions were unmistakable.

Garvey backed away, step by step. He noticed that the surrogate was beginning to breathe heavily. Panic overtook him then, and he sprinted through the cabin door, slamming it behind him. The surrogate smashed against the door, calling to him in a clear, wordless voice. Garvey went to the instrument panel and began to evacuate the air from the after cabin.

Dial hands began to swing. Garvey heaved a sigh of relief and collapsed into a chair. It had been a close thing. He didn't like to think what would have happened if the Algolian sexual substitute had managed to seize him. Probably he would not have lived through the experience. He felt sorry at the necessity of killing so magnificent a creature, but it was the only safe thing to do.

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.
