Christie, who had just published her sixth novel, “The Murder of Roger Ackroyd,” had holed up at a hotel and spa where she had gone unrecognized. And she also wrote the world’s longest-running play (“The Mousetrap”).īut while Christie’s detectives Hercule Poirot and Miss Marple were celebrated for revealing all the secrets at story’s end, Christie left one mystery unsolved in her real-life: In 1926, Christie, then 36, abandoned her car and disappeared for 11 days, inciting a media frenzy and setting off a nationwide manhunt. Agatha Christie was the master of mystery: Books like “Murder on the Orient Express” and “Death on the Nile” made her the world’s best-selling author (two billion copies sold) and have been adapted into scores of films, attracting directors such as Billy Wilder, Sidney Lumet and Kenneth Branagh.
