Her writing career spanned more than half a century, during which she wrote 79 novels and short story collections, as well as 14 plays, one of which, The Mousetrap, is the longest-running play in history. Two of the characters she created, the brilliant little Belgian Hercule Poirot and the irrepressible and relentless Miss Marple, went on to become world-famous detectives. Both have been widely dramatized in feature films and made-for-TV movies.
Agatha Christie also wrote six romantic novels under the pseudonym Mary Westmacott. As well, she wrote four nonfiction books including an autobiography and an entertaining account of the many expeditions she shared with her archaeologist husband Sir Max Mallowan.
