The summer evening came slowly. The sun sank down behind a ragged line of trees in the distance and the sky paled. The twilight was languid and soft. There was a white full moon, and low purple clouds lay over the horizon. The earth, the trees, the unpainted rural dwellings darkened slowly. At intervals mild summer lightning quivered in the air. Singer watched all of this intently until at last the night had come, and his own face was reflected in the glass before him.
