A letter for Miss Marple from a recently deceased friend promises a large reward for investigating a crime - without telling her who was involved, or when it happened! When she accepts, she is given a reservation for a coach tour of historic homes and gardens. She has fifteen fellow-passengers - and one of them knows a murderer's secret and someone is preparing to kill.

BBC版的马普尔还是很忠实原著的，这个故事比itv那版乱改的好看。喜欢这版的片头很古典画风，案件里的英国乡村好美
