Christie created two of literature's most beloved fictional detectives: the brilliant Belgian sleuth Hercule Poirot and the sharp-witted elderly spinster Miss Marple. Her masterpiece, The Murder of Roger Ackroyd (1926), stunned readers with its innovative plot twist, while Murder on the Orient Express (1934) and Death on the Nile (1937) showcased Poirot's genius in exotic settings. Perhaps her most celebrated work, And Then There Were None (1939), is one of the best-selling novels of all time and is praised for its ingenious plot structure.
Beyond novels, Christie wrote The Mousetrap, the world's longest-running play, which has been performed continuously in London since 1952. She also wrote romance novels under the pseudonym Mary Westmacott. Honored as a Dame of the British Empire in 1971, Christie's intricate plots, memorable characters, and masterful storytelling continue to captivate readers and inspire countless adaptations across film, television, and theater.
