The story in one page
At Styles Court, an Essex estate, the matriarch dies after consuming strychnine-laced cocoa. With the household thick with resentment and hidden debts, suspicion falls immediately upon her recent husband, Alfred Inglethorp. Hercule Poirot, a Belgian refugee staying nearby, ignores the obvious evidence to focus on a broken bell-pull, a missing will, and a burned letter. He navigates a web of domestic tension involving John Cavendish, his wife Mary, and various houseguests. As official police move toward an arrest, Poirot maneuvers behind the scenes to discredit the local investigation. By the time he presents his final explanation, he has not only secured a confession from the actual killer but also forced the fractured Cavendish household into a sudden, unexpected reconciliation.
