"Especially in an English village - turn over a stone, you have no idea what will crawl out", spinster detective Miss Marple tells Inspector Craddock during their first meeting over tea and crumpets. Agatha Christie's most popular character has her own techniques to deal with such mysteries: thorough observation, polite questioning, a keen insight into the human mind - and the reassuring click of knitting needles. Joan Hickson played the amateur sleuth, Miss Marple, from 1984 to 1992. Her portrayal of Jane Marple is widely considered to be the finest and has earned her two BAFTA nominations. Celebrated actress Joan Hickson makes her mark once more in this period thriller as Jane Marple, a determined lady with an unassuming air and a flair for solving crime. "Stonygates" is a home for young offenders run by Lewis Serrocold. When he's threatened with a gun at a family gathering, he ushers Edgar out and calmly takes control. Shots are heard and the body of a relative is discovered in another room. Something odd about the murder is compounded by a second death until Miss Marple stumbles on a conjuring set. Hey presto! A little magic of her own reveals the killer's trick.
