A small English village is shaken by the death of a wealthy local; the narrator, a local physician, recounts events and the arrival of a retired Belgian detective who investigates. Through interviews, household facts, and the patient unravelling of alibis, suspicion falls on several acquaintances, and private motives and secrets emerge. The investigation uses observation, logical deduction, and careful reconstruction of timelines; the detective convenes key figures to reveal how seemingly straightforward evidence conceals a deliberate deception. Themes include the unreliability of appearances, the social texture of village life, and the moral complexities behind ordinary lives.
