 Why are there three women and one man in the home?
The house was furnished with all luxuries, including women. If it only had a lease that could be broken— Roger Tennant, crossing the lawn, could see two of the three wings of the house, which radiated spoke-like from its heptagonal central portion. 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. 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. 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. The other two women were sitting in the heptagonal central hall. Eudalia, who had borne twin girls recently, was lying back, newly thin and dark of skin and hair, smoking a scentless cigarette. A tall woman, thirtyish, she wore a sort of shimmering green strapless evening gown. Tennant wondered how she maintained it in place, for despite her recent double motherhood, she was almost flat of bosom. Eudalia had been a female foreman in a garment-cutting shop before being captured and brought through. 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. "I don't feel at ease in a harem, even when it's supposedly my own." "But he doesn't have to—have them," objected Olga. "Let's get the meal ordered," said Dana and they were all silent, thinking of what they wanted to eat but would not enjoy when it came. It arrived before the meal, materializing against one of the seven walls of the roofless chamber. Tennant watched the girls as a sweet-voiced crooner began to ply an unfamiliar love lyric to a melody whose similarity to a thousand predecessors doomed it to instant success.
