About the book
At Stonygates, an English country house that doubles as a rehabilitation center for young offenders, Miss Marple visits her old friend Carrie Louise Serrocold. Carrie Louise’s sister Ruth has asked her to look into an uneasy feeling about the household. When shots are heard during a confrontation involving Lewis Serrocold, Carrie Louise’s husband and the center’s administrator, a visitor is found murdered elsewhere in the house.
Reader notes
Conversation drives this country-house whodunit, as Miss Marple sorts through what people saw and heard. The puzzle requires keeping a tangled family and precisely timed movements straight, so the main challenge lies in following testimony and household relationships.

About the author
Agatha Christie
Agatha Christie (1890–1976) was an English mystery writer associated with the Golden Age of Detective Fiction. After six rejections, she established her career in 1920 with The Mysterious Affair at Styles, which introduced Hercule Poirot. Much of her fiction places a limited group of suspects in a confined social setting, such as a country house, train, boat, or island, then tests their accounts against physical clues and private motives. Her direct, dialogue-led prose keeps these investigations clear while giving weight to discrepancies in testimony and behavior. Poirot exemplifies this attention to both material evidence and human conduct. Across her work, Christie returned to concealed relationships, guilt, unreliable witnesses, and the tension between establishing what happened and deciding what justice requires.
