A young woman trapped in a stifling household is pushed into a passionless marriage and becomes involved in an intense affair with a friend; their illicit relationship leads them to murder her sickly husband, after which they marry but are gradually consumed by guilt, revulsion, and psychological decay. The victim’s mother, left physically impaired yet mentally observant, endures the secret while the lovers’ mutual hatred intensifies, producing paranoia and violent unraveling. The narrative follows naturalistic, detail-rich observation of bodies and environments, showing how temperament, heredity, and surroundings corrode conscience and ultimately destroy lives.
