As he is being killed, Alfred cries out his killer's name. When the whole family fall ill, Quimper visits all of them in turn and kills Alfred in his bed by a fatal injection. Quimper planted a small does of poison in the family dinner. Alfred, however, saw Quimper plant the false clue and blackmailed him (there is a scene of Alfred boasting to Lucy that he is due to receive some money). Alexander and James found this clue and gave it to the police. So Quimper planted a false clue on the grounds (a sales receipt made out to Mrs M Crackenthorpe). So long as the murder victim was thought to be Martne, suspicion would fall on the Crackenthorpe family. Both the motive for killing Alfred, and the method of his murder, were changed.The murder which Elspeth McGillicudy witnessed on the train was not that of Martine. For a long time, the body found in the mausoleum was presumed to be Martine, but later Martine is found, alive and well. The visit is marred by Harold, who sexually assaulted her. He brought her home to meet all his family. Edmund married Martine, a French girl, during the war. In this adaptation she has a slightly different backstory. Like in the original, 'Martine' features heavily in the story and the plot twist involving her is followed fairly faithfully.In addition, Edith is described as dying during childbirth. Edmund is killed by a U-Boat in the Atlantic in December 1941 and considered to be lost at sea.Only two murders occur – Quimper's wife, and Alfred.Bryan is British in the novel, but American in the adaption.This adaption ends with Lucy rejecting the two Crackenthorpe men in favour of the inspector. The novel's Inspector Dermot Craddock is replaced by Inspector Tom Campbell, an old friend of Miss Marple.The name of Luther's father is changed from Josiah to Marcus and he manufactured confectionery rather than tea biscuits.In this version, Alfred is the eldest son after Edmund, and will inherit the Hall Harold is the second-eldest son (He becomes next-in-line to inherit the Hall after Alfred dies) and Cedric is the youngest son.His motive for murdering his wife is his love for Emma rather than his desire for the Crackenthorpe inheritance. His character was changed to be more sympathetic than he is in the novel. Dr Quimper's first name, not mentioned in the novel, is given as David.
