Dame Agatha Mary Clarissa Christie (née Miller; 1890–1976), known as Agatha Christie, was a British author renowned for her 66 detective novels and 14 short story collections featuring iconic detectives Hercule Poirot and Miss Marple. She adopted the surname Christie upon marrying Colonel Archibald Christie in 1914, a name under which she gained international fame. Agatha also wrote six novels under the pseudonym Mary Westmacott. Her play The Mousetrap holds the record as the world's longest-running play, continuously performed in London's West End since 1952. Celebrated as the "Queen of Crime," she was a pivotal figure during the Golden Age of Detective Fiction. In 1971, Queen Elizabeth II honored her with a Damehood (DBE) for her contributions to literature. With over two billion copies sold, Christie remains the best-selling novelist of all time according to Guinness World Records.
