Marple is visiting an old school friend, Lady Camilla Tressilian, along with an eclectic group: Neville Strange and his wife Kay, his former wife Audrey and her childhood friend and cousin Thomas Royde, Ted Latimer and finally Freddie Treves, a retired solicitor. When Treves is found dead the day after a dinner party at Lady Tressilians home and Lady Tressilian herself is found bludgeoned to death a short time later, Miss Marple must sort through the complex set of relationships among all the players, and determine what role the tale of a childs crime may have had to play in the deaths.
