Hercule Poirot to Return in a New Christie Mystery

James Bond novels have carried on long beyond Ian Fleming. Decades after Margaret Mitchell’s death in 1949, “Gone With the Wind” spawned two sequels. In the latest continuation of a beloved literary property, a new Agatha Christie mystery will be released, the publisher said on Tuesday.

William Morrow, an imprint of HarperCollins, said the new novel, written by Sophie Hannah and fully authorized by the Christie estate, will feature one of her most famous characters, the fastidious Belgian detective Hercule Poirot. The novel, it said, is a “diabolically clever murder mystery sure to delight and baffle Christie’s fans, and those who have never read her work.”

Ms. Hannah, a best-selling author of crime fiction, said she hoped to “create a puzzle that will confound and frustrate the incomparable Hercule Poirot for at least a good few chapters.” It is planned for release next September.
