Agatha Christie is the best-selling author of all time. She wrote eighty crime novels and story collections, fourteen plays, and several other books. Her books have sold roughly four billion copies and have been translated into 45 languages. She is the creator of the two most enduring figures in crime literature—Hercule Poirot and Miss Jane Marple—and author of The Mousetrap, the longest-running play in the history of modern theatre. Christie was born in Torquay, Devon in 1890. She died in 1976 in Wallingford, Oxfordshire.
