Helen Eustis’s The Horizontal Man (1946) won an Edgar Award for best first novel and continues to fascinate as a singular mixture of detection, satire, and psychological portraiture. A poet on the faculty of an Ivy League school (modeled on Eustis’s alma mater, Smith College) is found murdered, setting off ripple effects of anxiety, suspicion, and panic in the hothouse atmosphere of an English department rife with talk of Freud and Kafka.
