The wing on the left was white, with slim square pillars, 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. Dana was lying under a tree near the door, stretched out on a sort of deck chair with her eyes closed. She wore a golden gown, long and close-fitting and slit up the leg like the gown of a Chinese woman. Above it her comely face was sullen beneath its sleek cocoon of auburn hair. Their captors had no idea of how a woven design should behave. "I don't even want to think about him," said Tennant. 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. Within the dome of the barrier, it looked more like a well-kept if bizarre little country estate. 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 was a prison, a cage. Eudalia, who had borne twin girls recently, was lying back, newly thin and dark of skin and hair, smoking a scentless cigarette. Eudalia had been a female foreman in a garment-cutting shop before being captured and brought through. 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. "Lay off—he can't help it," said Eudalia unexpectedly. "But he doesn't have to—have them," objected Olga. In fact, Tennant thought, only her laughter was unpleasant, a shrill, uncontrolled burst of staccato sound that jarred him to his heels. It arrived before the meal, materializing against one of the seven walls of the roofless chamber. A disc jockey's buoyant tones cut in quickly as the final ooooo faded.
