Agatha Christie

Agatha Mary Clarissa Miller was born on 15 September 1890 in Torquay, England. She was a crime writer of novels, short stories, and plays. She also wrote six romances under the name Mary Westmacott, but she is best remembered for the 66 detective novels and more than 15 short story collections she wrote under her own name, most of which revolve around the investigations of such characters as Hercule Poirot, Miss Jane Marple and Tommy and Tuppence. She also wrote the world's longest-running play The Mousetrap.

According to the Guinness Book of World Records, Christie is the best-selling novelist of all time. Her novels have sold roughly 4 billion copies, and her estate claims that her works rank third, after those of William Shakespeare and the Bible, as the world's most widely published books.

According to Index Translationum, Christie is the most translated individual author, and her books have 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.

Christie created the most iconic sleuths ever to grace the pages of murder mystery novels; Poirot and Miss Marple, as well as Tommy and Tuppence, Ariadne Oliver, Harley Quin, Parker Pyne, Hastings, and Chief Inspector Japp. (Click on them to know more)
