In the aftermath of the Second World War, the prosperous Cloade family is thrown into disarray when their wealthy patriarch, Gordon Cloade, is killed in a London air raid only weeks after a sudden marriage. His entire fortune passes to his young widow, Rosaleen, leaving his relatives, who had long relied on his generosity, resentful and financially stranded. The family's unease deepens when a stranger arrives in the quiet village of Warmsley Vale and signs the hotel register as Enoch Arden. He hints that Rosaleen's first husband, presumed dead, may still be alive, a claim that would shatter her marriage to Gordon and free the inheritance. When the stranger is found dead, suspicion spreads through a household already simmering with debt, jealousy, and concealed motives. Hercule Poirot, drawn into the affair through a chance encounter at his club, works alongside Superintendent Spence to untangle questions of identity, blackmail, and who stood to gain. Around the central puzzle, the novel traces the strained engagement of Lynn Marchmont, recently home from war service and restless in ordinary life, and her steadfast cousin Rowley. Christie sets a postwar England of rationing, returning soldiers, and shifting fortunes against a tightly plotted study of how money distorts loyalty, and how the dead are not always who they seem.
