Marple: A Pocketful of Rye

An Agatha Christie murder mystery based on the rhyme 'Sing a Song of Sixpence'.

Plot:

When wealthy Rex Fortescue dies while having tea, the police are baffled. Mr. Fortescue died during his morning tea in the office and the diagnosis was that a poison, taxine - a poison found as an alkaloid in berries of the yew tree, had killed him. His wife was the main suspect in the murder, until she also was murdered, after she as well drank the tea. Her lover, Mr. Dubois, was the suspect next, as well as just about everyone that knew the family. Going on the only clue, a pocket full of rye found on the victim, Miss Marple begins investigating. Marple realizes the murders are arranged according to the pattern of her childhood nursery rhyme 'Sing a Song of Sixpence'. Murder though, is anything but child's play. She works together with Inspector Neele on the case, who seems to have a very different idea of what happened.
