Agatha Christie has been referred to by the Guinness Book of World Records as the best-selling writer of books of all time and the best-selling writer of any kind, along with William Shakespeare. Only the Bible is known to have outsold her collected sales of roughly four billion copies of novels. UNESCO states that she is currently the most translated individual author in the world with only the collective corporate works of Walt Disney Productions surpassing her. Christie’s books have been translated into at least 103 languages.
Her stage play The Mousetrap holds the record for the longest initial run in the world: it opened at the Ambassadors Theatre in London on 25 November 1952 and as of 2010 is still running after more than 23,000 performances. In 1955, Christie was the first recipient of the Mystery Writers of America’s highest honour, the Grand Master Award, and in the same year, Witness for the Prosecution was given an Edgar Award by the MWA, for Best Play.
Her plays include: Spiders Web, The Hollow, Murder on the Nile, And Then There Were None, Verdict, Black Coffee, Witness for the Prosecution, The Unexpected Guest and many more adaptations.
