to their character—if such utterly alien creatures could be said to Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] The house was furnished with all reminiscent of scores of movie sets of the Deep South. That on the right was sundeck solar-house living-machine modern, something like a montage of shoeboxes. The wing hidden by the rest of the house was, he "Is this crop rotation or did you send for me?" she asked cynically. himself—desire that both of them loathed because it was implanted within them by their captors. They walked toward the house. It didn't look like a prison—or a cage. Within the dome of the barrier, it looked more like a well-kept if bizarre little country estate. There was clipped lawn, a scattering of trees, even a clear might have been cellophane but wasn't, and it sprouted from a fabric They entered the house, which had no roof, continued to move beneath a sky that glowed with light which did not come from a sun or moon. It might have been a well-kept if bizarre little country estate, but it wasn't. It was a prison, a cage. The other two women were sitting in the heptagonal central hall. Eudalia, who had borne twin girls recently, was lying back, newly thin "Okay, I guess," she said. "The way they manage it, there's nothing to it." She had a flat, potentially raucous voice. Eudalia had been a female foreman in a garment-cutting shop before being captured and brought through. still, regarding him over the pregnant swell of her dirndl-clad waist. Olga had been a waitress in a mining town hash-house near Scranton. Tennant wanted to put an encouraging hand on her shoulder, to say something that might cheer her up, for she was by far the youngest of the three female captives, barely nineteen. But with the eyes of the 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. It arrived before the meal, materializing against one of the seven be it gold, brown or red, it—are they—real?" aroma of steak, it was almost tasteless. This was so with all of their foods, with their cigarettes, with everything in their prison—or their cage. Their captors were utterly without a human conception of smell, living, apparently, in a world without odor at all. Dana said suddenly, "I named the boy Tom, after somebody I hate almost she's right, Dana. We're as helpless as—laboratory animals. They have the means to make us do whatever they want." all are. We seem to be in a universe of different properties as well as "Are we really in the fourth dimension?" Dana asked. Of the three of them, she alone had more than a high-school education. "We may be in the eleventh for all I know," he told her. "But I'll settle for the fourth—a fourth dimension in space, if that makes scientific sense, because we don't seem to have moved in time. I wasn't it's because they're pretty human." Human! considerable danger and, probably, expense of some kind. Some of them don't come back. They kill those of us who put up a fight. Those who don't—or can't—they bring back with them. Live or dead, we're just laboratory specimens." things they do—stuffing people, mounting their heads, keeping them on display in their—their whatever they live in. You call that human, Rog?" "Were you ever in a big-game hunter's trophy room?" Tennant asked quietly. "Or in a Museum of Natural History? A zoo? A naturalist's lab? Or even, maybe, photographed as a baby on a bear-skin rug?" "I was," said Olga. "But that's not the same thing." holding the gold dress casually over her bare arm. Eudalia took him to the nursery. He was irritated now in another, angrier way. The infants, protected by cellophane-like coverlets, were asleep. "And it's not yours," insisted Eudalia. "Don't let them make you think was , that was all. He called it the training hall, not because it looked like a training anything save some half-nourished dream a surrealist might have discarded as too nightmarish for belief. As in all of this strange universe, excepting the dome-cages in which the captives were held, the training hall followed no rules of three-dimensional space. One wall looked normal for perhaps a third of its length, then it simply wasn't for a bit. It came back farther on The captor Tennant called Opal came in through a far corner of some unseen direction. He had no regular shape and much of him was and Opal would have shown no reaction. Yet Tennant suspected that the captors could hear somewhere along the auditory scale, just as perhaps they could smell, although not in any probing investigation. Opal, like the rest of the captors, was as curious as a cat—or a human being. Tennant sat against a wall, drenched with sweat. There would be endless repetition before his workout was done. On Earth, dogs were said to be intellectually two-dimensional creatures. He wondered if they felt this have been the interior of a giant concertina—or an old-fashioned kodak. sort of ultradimensional television set, but to Tennant it was as incomprehensible as an oil painting to an animal. He asked Opal where and when they were going, was informed that he would soon emerge on Earth where he had left it. That told him everything but the date and season. Opal, like the rest of the captors, seemed to have no understanding of time in a human sense. Waiting, Tennant tried not to think of his wife, of the fact that he 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. 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, 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 adolescent's. This hunger was real, not implanted. Everything would be Opal had been too interested in the next lab specimen to bother about power over him. Women have waited longer than eighteen months. He would have if his captors had let him. "Where in hell have revolting. What "You bastard," said Cass. "You dirty bastard! You know what a wait like that could do to us." "Tristan and Isolde," said Tennant, grinning almost happily. "Well, He needed no telepathic powers to read the thoughts around him then. He had been sitting there, unconscious, ripe fruit on their doorstep. They had simply picked him up. Otherwise, apparently, men were next to impossible for them to capture. All they could do was kill them and bring back their heads and hides as trophies. With women it was different—perhaps the captors' weapons, body chemistry or psychology, perhaps. More than once, during his long training with Opal, Tennant had sent questing thoughts toward his captor, asking why they didn't simply set up the gateway in some town or city and take as many humans as they wanted. a blowgun, to set up shop in the midst of a herd of wild elephants.
