 Why are there three women and one man in the home?
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. Their captors had no idea of how a woven design should behave. 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. 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. It arrived before the meal, materializing against one of the seven walls of the roofless chamber. Dana stood almost in the center of the room, carmine-tipped fingers clasped beneath the swell of her breasts. This was so with all of their foods, with their cigarettes, with everything in their prison—or their cage. We seem to be in a universe of different properties as well as different dimensions. Of the three of them, she alone had more than a high-school education.
