Although the evidence appears to be overwhelming in the strangulation murder of a blackmailer, Miss Marple's sole 'not guilty' vote han gs the jury 11-1. She becomes convinced that the real murderer is a member of a local theatrical troupe, so she joins them in order to gather information. The clues lead back many years to a single disastrously unsuccessful 1951 performance of a dreadful play written by the group's hammy director, H. Driffold Cosgood. Although at that time, several of the current cast members were only children, more murders follow before Miss Marple ultimately exposes the killer. 英国影片。片少90分，根據Mrs. McGinty's Dead改編，本著是波羅故事。果影片将主角酿成马普我蜜斯战剧情的更改引收本小說做者克里斯蒂凶猛没有谦，影片自身也遭遇票房战指摘惨败。主演Margaret Rutherford借出演過另中3部以马普我蜜斯为主角的影戏，其中1部亦是依据波洛故事改编(「葬礼以后」)，另1部是本创剧本。80年月正在多部电视剧中饰演塔彭丝的Francesca Annis也正在本片中饰演一个小脚色。
