could easily have been Poirot novels, represent a logical endpoint of the general diminution of his presence in such works. Towards the end of his career, it becomes clear that Poirot's retirement is no longer a convenient fiction. He assumes a genuinely inactive lifestyle during which he concerns himself with studying famous unsolved cases of the past and reading detective novels. He even writes a book about mystery fiction in which he deals sternly with Edgar Allan Poe and Wilkie Collins. In the absence of a more appropriate puzzle, he solves such inconsequential domestic riddles as the presence of three pieces of orange peel in his umbrella stand. Poirot (and, it is reasonable to suppose, his creator) becomes increasingly bemused by the vulgarism of the up-and-coming generation's young people. In Hickory Dickory Dock, he investigates the strange goings-on in a student hostel, while in Third Girl (1966) he is forced into contact with the smart set of Chelsea youths. In the growing drug and pop culture of the sixties, he proves himself once again but has become heavily reliant on other investigators (especially the private investigator, Mr. Goby) who provide him with the clues that he can no longer gather for himself.

This took place at Styles Court, the scene of his first English case in 1916. In Christie's novels, he lived into the early 1970s, perhaps even until 1975 when Curtain was published. In both the novel and the television adaptation, he had moved his amyl nitrite pills out of his own reach, possibly because of guilt. He thereby became the murderer in Curtain, although it was for the benefit of others. Poirot himself noted that he wanted to kill his victim shortly before his own death so that he could avoid succumbing to the arrogance of the murderer, concerned that he might come to view himself as entitled to kill those whom he deemed necessary to eliminate. The "murderer" that he was hunting had never actually killed anyone, but he had manipulated others to
