He realized, shocked and scared, that his thoughts of escape had slipped past his mental censor, and he waited apprehensively for Opal to strike. Nothing happened and he warily relaxed. Opal wasn't tapping his thoughts. Because he felt sure of his captive ... or because he couldn't on Earth?
It was like being let out of a cage. Tennant grinned at the bookcase; the ebony-and-ivory elephants that Agatha had never liked were gone, but he'd get them back or another pair. The credenza had been replaced by a huge and ugly television console. That, he resolved, would go down in the cellar rumpus room, where its bleached modernity wouldn't clash with the casual antiquity of the living room.
Agatha would complain, naturally, but his being back would make up for any amount of furniture shifting. He imagined her standing close to him, her lovely face lifted to be kissed, and his heart lurched like an adolescent's. This hunger was real, not implanted. Everything would be real ... his love for her, the food he ate, the things he touched, his house, his life....
Your wife and a man are approaching the house.
The thought message from Opal crumbled his illusion of freedom. He sank down in a chair, trying to refuse to listen to the rest of the command:
You are to bring the man through the gateway with you. We want another live male.
Tennant shook his head, stiff and defiant in his chair. The punishment, when it came, was more humiliating than a slap across a dog's snout. Opal had been too interested in the next lab specimen to bother about his thoughts—that was why he had been free to think of escape.
Tennant closed his eyes, willed himself to the front window. Now that he had mastered teleportation, it was incredible how much easier it was in his own world. He had covered the two miles from the gateway to the house in a mere seven jumps, the distance to the window in an instant. But there was no pleasure in it, only a confirmation of his captor's power over him.
He was not free of them. He understood all too well what they wanted him to do; he was to play the Judas goat ... or rather the Judas ram, leading another victim to the fourth-dimensional pen.
