Louise Henderson is trapped in a nightmare: the baby cries almost all night, every night, and the other children must be gotten off to school . . . Louise is so tired that she is afraid she is becoming psychotic; why does she have this feeling of apprehension, almost of terror? Is it connected with the lodger, a respectable school teacher? What is happening in the Henderson household? This novel, which won an Edgar in 1957, is one to be read in a single sitting.
