THE hills across the valley of the Ebro were long and white. On this side there was no shade and no trees and the station was between two lines of rails in the sun. Close against the side of the station there was the warm shadow of the building and a curtain, made of strings of bamboo beads, hung across the open door into the bar, to keep out flies. The American and the girl with him sat at a table in the shade, outside the building. It was very hot and the express from Barcelona would come in forty minutes.
