BBC出品的《东方快车谋杀案》中,波洛在最后揭露出凶手后,曾与之辩驳:The rule of law,it must be held high!And if it falls,you pick it up and hold it even higher!For all society all civillized people will have nothing to shelter them if it is destroyed(法律必须高于一切,即便有失公允,也该充实信念,使其历久弥坚,法律信念一旦崩塌,文明社会将无栖息之所)!尽管在原文中,阿婆倒更显得含糊不清:对待私刑者,付诸正义或是法律,她就像小说中的波洛一样推的干干净净:我宣布正式退出这个案子!其实这才是最聪明的做法,见仁见智,应该交给读者。
