在发现儿歌的同时，他们还在一个圆形的桌子上看到了十个精致的小瓷人。

就在他们享用晚餐的时候，留声机响起，那个声音的主人指控那里的每一个人都犯有谋杀罪。正在众人恐慌之时，安东尼·马尔斯顿突然死掉了。他看起来是被呛死的，但实际上是被氰化物毒死。与此同时，男管家罗杰斯惊讶地发现桌子中间的小瓷人少了一个。在他们还处于惊恐中时，托马斯·罗杰斯的太太——艾塞尔·罗杰斯永远地睡着了，小瓷人也神奇地只剩八个了。接下来，麦克阿瑟将军在海边被重击致死，只剩七个了。杀戮还没有结束，一把大砍刀害死了罗杰斯，还剩六个。在一只野蜂出现在别墅后，埃米莉·布伦特也死去。

那个在每个人房里的古老的童谣，与死者的死亡惊人地巧合。也就在这时，他们意识到凶手就在他们中间。于是，他们采取了各种防范措施，但凶手似乎永远比他们更快、更隐蔽、更狡猾。接着，法官沃尔格雷夫先生被枪射死（他是假死的，阿姆斯特朗医生假装法官被杀），阿姆斯特朗医生在波涛汹涌的大海中溺水而亡，布洛尔的脑袋被一块熊般大的大理石砸碎。现在，只剩韦拉和隆巴尔德了。韦拉抢到了隆巴尔德的左轮手枪，射死了隆巴尔德。岛上只剩韦拉一个人了，“一个小小战士太孤单”，最后，她“吊死了自己”，“一个都不留”。

在这个荒凉又阴森的小岛上，只剩下十具尸体，无人生还。

苏格兰场接了这起神秘的案子，他们很快找到了十个人的尸体并确认了死因，但却完全无法解释事件的经过，直到他们意外收到凶手（法官劳伦斯·瓦格雷夫）的信件，详细描述自己的作案动机和作案过程，而且说他写完信后用机关自杀，案件的真相终于被揭晓。
