Agatha Mary Clarissa, Lady Mallowan, DBE (15 September 1890 – 12 January 1976), commonly known as Agatha Christie, was an English crime fiction writer. She also wrote romance novels under the name Mary Westmacott, but is best remembered for her 80 detective novels and her successful West End theatre plays. Her works, particularly featuring detectives Hercule Poirot or Miss Jane Marple, have given her the title the 'Queen of Crime' and made her one of the most important and innovative writers in the development of the genre.
Christie has been called — by the Guinness Book of World Records, among others — the best-selling writer of books of all time, and the best-selling writer of any kind together with William Shakespeare.
