This whodunit series based on Dame Agatha Christie's crime novels and short stories, was named after its star sleuth, Hercule Poirot (David Suchet), a famous former Belgian Policeman, who settled for good in London after the war, soon so famous as an infallible private detective that he becomes a society figure in his own right. In each episode, Poirot gets to solve a crime mystery, mostly murder(s), for a paying client or otherwise catching his attention, generally along with his faithful English sidekick Captain Hastings (Hugh Fraser) and/or his Scotland yard "friendly rival" Chief Inspector Japp (Philip Jackson).
