Synopsis: Miss Marple is visiting an old school friend, Lady Camilla Tressilian, along with an eclectic group: tennis star Nevile Strange, his wife Kay, his ex-wife Audrey, Kay's friend Ted Latimer, Audrey's friend Thomas Royde, and finally Freddie Treves, a retired solicitor. When Treves is found dead the day after a dinner party, and Lady Tressilian herself is found bludgeoned to death a short time later, Miss Marple must sort through the complex set of relationships and determine what role a tale of a child's crime may have had to play in the deaths.
