And Then There Were None is a mystery novel by English writer Agatha Christie, her best selling novel and described by her as the most difficult of her books to write.[2] It was first published in the United Kingdom by the Collins Crime Club on 6 November 1939, as Ten Little Niggers,[3] after the minstrel song, which serves as a major plot point.[4][5]

The US edition was released in January 1940 with the title And Then There Were None, which is taken from the last five words of the song.[6] All successive American reprints and adaptations use that title, except for the Pocket Books paperbacks published between 1964 and 1986, which appeared under the title Ten Little Indians.[citation needed]
