Major Palgrave, an idiosyncratic but charming mystery writer, reveals to Miss Marple that one of the guests at a luxurious Caribbean resort they're staying at is a Bluebeard-type wife murderer. Unfortunately, the Major succumbs to an apparently accidental overdose of alcohol and blood pressure medication before revealing the killer's identity. When it's discovered that the medicine belonged to another guest and the revealing photograph the Major was carrying is missing, Miss Marple realizes that the serial killer has struck again and more murders will follow
阿加莎的剧本依然是在日常的活动中，渗入丝丝缕缕的线索，最后再慢慢一一揭开，很有悬疑感。
几个主要人物都挺可爱的。女主老奶奶马普尔小姐好优雅，一把年纪依然腰背挺直，言语也有贵族的优雅和适度的傲气。也是个很聪明的女人，小跑步很轻快敏捷。
少校还在到处旅游，记录各种奇闻轶事，这似乎是很棒的老年生活。可惜在这个故事里早早领了盒饭。
后面马普尔小姐和拉斐尔先生斗嘴，一起研究案情挺好玩的，来个含蓄的黄昏恋也挺可爱的。
老奶奶还有句话说的很好：我一点都不觉得自己老了，我现在感觉和17岁一样，除了那时候我可怜所有20岁以上的人，现在却不了。
