50 free Hercule Poirot trivia questions with answers — literature quiz, new questions added Aug 2026.
Hercule Poirot appeared in 33 novels and dozens of short stories over 55 years, and when Agatha Christie finally killed him off he became the only fictional character to get a front-page obituary in The New York Times. This quiz covers the whole of that career: his refugee arrival at Styles, the famous cases on the Orient Express and the Nile, his obsessive habits and egg-shaped head, the friends and foils around him, and the long line of actors from Charles Laughton to David Suchet and Kenneth Branagh who have worn the moustache. It is built for Christie readers and Poirot binge-watchers alike. The opening questions are the ones any fan can get; the later ones reach into Poirot's shadowy police career in Brussels, his preferred bank balance and the plays and films most people have never heard of. Every answer was checked against Wikipedia's articles on the character, the major novels and the ITV series, and each question carries the sentence that supports it. If you enjoy this, our Agatha Christie quiz covers the author herself.
