Agatha Christie

Agatha Christie (1890–1976) was a British author best known for her detective novels, particularly those featuring Hercule Poirot and Miss Marple. Often referred to as the "Queen of Crime," she wrote 66 detective novels, 14 short story collections, and the world's longest-running play, The Mousetrap. Her books have sold over two billion copies, making her one of the best-selling authors in history. Christie was also a pharmacist during World War I, which gave her detailed knowledge of poisons—a key element in many of her stories. In 1971, she was made a Dame of the British Empire for her contributions to literature.
