50 free Agatha Christie trivia questions with answers — literature quiz, new questions added Aug 2026.
42 free Agatha Christie trivia questions with answers. Agatha Christie sold more than two billion books, and this quiz is for the readers who have worked through a good share of them. Forty-two questions cover Hercule Poirot's little grey cells and his New York Times obituary, Miss Marple's village of St Mary Mead, Tommy and Tuppence, Ariadne Oliver and Captain Hastings, plus the great novels: The Mysterious Affair at Styles, The Murder of Roger Ackroyd, Murder on the Orient Express, And Then There Were None, Death on the Nile and Curtain. The life gets equal billing: her Torquay childhood, the hospital dispensary work that taught her poisons, the eleven days she went missing in 1926, the archaeologist she married, the Mary Westmacott pen name, Greenway, and The Mousetrap's record-breaking run. Easy questions ask who Poirot is; hard ones want the hotel where she was found and the play she wrote for Queen Mary. Every answer was checked against Wikipedia's articles on Christie and her works, and each question carries the sentence that supports it.
