Colonel Lucius Protheroe is probably the least-liked individual in St Mary Mead. All resent his superior and demanding attitude. So, when he is found dead in the vicarage study, there is no end of suspects. His wife Ann was having an affair with a local artist, Lawrence Redding. His daughter Lettice bridled under his strict rule. There is also the vicar and his assistant, whom Protheroe suspected of stealing church funds. Finally, there is the mysterious Mrs. Lester with whom he clearly had some previous connection. Jane Marple, recuperating at home from a sprained ankle, had a bird's eye view of all the comings and goings at the vicarage around the time of the murder and she gladly assists Inspector Slack in solving the crime.

When Rex Fortescue dies while sitting at his desk in the City, it's determined that he was in fact poisoned. He was married to a much younger wife, who now stands to inherit. His son Percival, a partner in the family firm, was a disappointment to him and a daughter, Elaine, hasn't amounted to much. Another son, Lance, had a falling out with his father many years before and relocated to East Africa. He suddenly appears soon after his father's death claiming that they had reconciled and been invited by him to return to England with an offer to rejoin the firm. Miss Marple takes a particular interest in the case when her former maid Gladys, now working in the Fortescue household, is also murdered. She soon learns that the elder Fortescue had received veiled threats for some time and that they might have something to do with a long ago business deal that made his initial fortune.

"因为我看见的时候并不知道是谋杀。我是说，过了好久之后我才意识到是谋杀。还是两三个月以前谁说了句什么话才让我想起来。我见到的的确是一场谋杀案。" 当这句话从乔伊斯嘴里说出来时，在场准备万圣节前夜晚会的所有人都没把它当真，因为她一直是个喜欢说谎的孩子。所有的人都认为，她只是想引起著名侦探小说家奥利弗夫人的注意才这样说的。 乔伊斯真的说谎了吗？！ 看来没有！！！ 当晚的晚会上，她被人强行摁入一个装了水的大铁桶里淹死了。那个桶是用来玩咬苹果游戏的，这让奥利弗夫人从此不再吃苹果（改吃枣了）。 波罗应邀来了。他走访了每一个在场的人，并搜集符合条件的旧案的每一点信息。 然而，波罗得出的结论是：乔伊斯的确说谎了！！！ 那她为什么被杀呢？！
