All told, along a three-hundred-mile stretch, I found twenty-six Chinese lingerie dealers: four in Sohag, twelve in Asyut, two in Mallawi, six in Minya, and two in Beni Suef. It was like mapping the territory of large predator cats: in the Nile Valley, clusters of Chinese lingerie dealers tend to appear at intervals of thirty to fifty miles, and the size of each cluster varies according to the local population. Cairo is big enough to support dozens.
