Page "Hercule Poirot" Paragraph 65

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 the Third Girl 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.
