Author: Agatha Christie
Dame Agatha Mary Clarissa Christie, DBE (née Miller; 15 September 1890 – 12 January 1976) was an English crime novelist, short story writer, and playwright. She also wrote six romances under the name Mary Westmacott, but she is best known for the 66 detective novels and 14 short story collections she wrote under her own name, most of which revolve around the investigations of such characters as Hercule Poirot, Jane Marple, Parker Pyne, Harley Quin/Mr Satterthwaite, and Tommy and Tuppence Beresford. She wrote the world's longest-running play, The Mousetrap.
Born into a wealthy upper-middle-class family in Torquay, Devon, Christie served in a hospital during the First World War, before marrying and starting a family in London. She was initially unsuccessful at getting her work published; but in 1920 The Bodley Head press published her novel The Mysterious Affair at Styles, featuring the character of Hercule Poirot. This launched her literary career.
Guinness Book of World Records lists Christie as the best-selling novelist of all time. Her novels have sold roughly 2 billion copies, and her estate claims that her works come third in the rankings of the world's most-widely published books, behind Shakespeare's works and the Bible. According to Index Translationum, She remains the most-translated individual author – having been translated into at least 103 languages.And Then There Were None is Christie's best-selling novel with 100 million sales to date, making it the world's best-selling mystery ever, and one of the best-selling books of all time. In 1971, she was made a Dame by Queen Elizabeth II at Buckingham Palace.
