<passage>:
She said, "I'd rather be dead. Maybe I am. Maybe we're all dead and this is Hell." He stood over her and looked down until she turned away her reddening "Don't flatter yourself," she replied angrily. She sat up, pushed back her hair, got to her feet a trifle awkwardly because of the tight-fitting tubular gown. "If I could do anything about it...." "But you can't," he told her. "They're too clever." "Is this crop rotation or did you send for me?" she asked cynically. "If you did, I wish you hadn't. You haven't asked about your son." "I don't even want to think about him," said Tennant. "Let's get on with it." He could sense the restless stirring of the woman within Dana, just as he could feel the stirring toward her within himself—desire that both of them loathed because it was implanted within them by their captors. They walked toward the house. double motherhood, she was almost flat of bosom. He asked her how she was feeling. "Okay, I guess," she said. "The way they manage it, there's nothing still, regarding him over the pregnant swell of her dirndl-clad waist. other two, especially Dana, upon him, he could not. "I guess I wasn't cut out to be a Turk," he said. "I don't feel at ease in a harem, even when it's supposedly my own." "You're not doing so badly," Dana replied acidly. "Lay off—he can't help it," said Eudalia unexpectedly. "He doesn't like it any better than we do." "But he doesn't have to—have them," objected Olga. She had a trace of Eudalia laid down her fork with a clatter and regarded Dana disapprovingly. "Why take it out on Rog?" she asked bluntly. "He didn't ask to come here any more than we did. He's got a wife back home. Maybe you want him to fall in love with you? Maybe you're jealous because he doesn't? Well, maybe he can't! And maybe it wouldn't work, the way things are arranged here." her close, although neither of them felt desire at the moment. Their captors had seen to that "And it's not yours," insisted Eudalia. "Don't let them make you think it is." "I'll try not to," he said and stopped, realizing the family party was over. He had felt the inner tug of command, said good-by to the women and returned to his smaller compound within its own barrier dome. Opal was nervous, so much so that he revealed more than he intended. Or perhaps that was his intent his role was to be. He had little time to speculate before Opal seemed to envelop him. that might have made Opal suspicious. He should be somewhat excited. He allowed himself to be, though he obscured the reasons. He was going to see his wife again ... and maybe he could trick his way into not returning. He shrugged, returned to the feeling of comfort that came from being back here, about to see Agatha again, hold her close in no more than a few minutes. And stay, his mind began to add eagerly, but he pushed the He took another deep, lung-filling drag on his cigarette, looked around the room that was so important a part of his life. The three women back there would be in a ghastly spot. He felt like a heel for wanting to leave them there, then knew that he would try somehow to get them out. Not, of course, anything that would endanger his remaining with Agatha the only way his captors would get him back would be as a taxidermist's specimen. He realized, shocked and scared, that his thoughts of escape had 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: 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. . He'd had one too many and only wanted a little fun. Really, darling, you seem to think that a girl...." groomed, more assured than his memory of her. "I'm no stuffed-shirt and you know it." Cass' tone was peevish. "But your idea of fun, Agatha, is pretty damn...." It was his turn to freeze. Unbelieving, Tennant studied his successor. Cass Gordon—the man , the ex-halfback whose bulk was beginning to get Roger! he should have expected a triangle, but somehow he hadn't. And here it was, with all of them going through their paces like a trio of "Sorry," said Tennant. "I've had my troubles, too." Agatha was scared stiff—of him. Probably with reason. He looked again at Cass Gordon and found that he suddenly didn't care. She couldn't say it was loneliness. Women have waited longer than eighteen months. He would have if his captors had let him. you been, Rog?" Gordon's tone was almost Agatha looked at him over the rim of hers. "Tell us, Rog. We have a He was standing no more than four inches from this woman he had desired desperately for six years, and he no longer wanted her. He was acutely conscious of her perfume. It wrapped them both like an exotic blanket, and it repelled him. He studied the firm clear flesh of her cheek and chin, the arch of nostril, the carmine fullness of lower lip, the swell of bosom above low-cut gown. And he no longer wanted any of it or of her. Cass Gordon— It didn't have to be anybody at all. For it to be Cass Gordon was revolting. "Rog," she said and her voice trembled, "what are we going to do? What she wouldn't know what that meant. It would serve her right, but maybe there was another way. "I don't know about you," he said, "but I suspect we're in the same boat. I also have other interests." "You louse!" said Cass Gordon, arching rib cage and nostrils. "If you try to make trouble for Agatha, I can promise...." " What can you promise?" demanded Tennant. When Gordon's onset subsided in mumbles, he added, "Actually, I don't think I'm capable of making more than a fraction of the trouble for either of you that you both are qualified to make for yourselves." He lit a cigarette, inhaled. "Relax. I'm not planning revenge. After this evening, I plan to vanish for good. Of course, Agatha, that offers you a minor nuisance. You will have to wait six years to marry Cass—seven years if the maid who let me in tonight talks. That's the law, isn't it, Cass? You probably had it all figured out." that could do to us." "Tristan and Isolde," said Tennant, grinning almost happily. "Well, I've had my little say. Now I'm off again. Cass, would you give me a He needed no telepathic powers to read the thoughts around him then. He heard Agatha's quick intake of breath, saw the split-second look she exchanged with Cass. He turned away, knowing that she was imploring her lover to do something, anything
