And Then There Were None is a
mystery novel by
Agatha Christie, widely considered her
masterpiece and described by her as the most difficult of her books to write. It was first published in the United Kingdom by the
Collins Crime Club on 6 November 1939 as
Ten Little Niggers, after the British blackface song, which serves as a major plot point. The U.S. edition was not released until December 1939 with the title changed to the last five words in the original American version of the nursery rhyme,
And Then There Were None. In the U.S., it was both adapted and reprinted as
Ten Little Indians.
