And Then There were none

And Then There Were None is a detective fiction novel by Agatha Christie, first published in the United Kingdom by the Collins Crime Club on 6 November 1939 under the title Ten Little Niggers which was changed because of the presence of a racial epithet by Dodd, Mead and Company in January 1940 under the title And Then There Were None. In the novel, ten people, who have previously been complicit in the deaths of others but have escaped notice or punishment, are tricked into coming onto an island. Even though the guests are the only people on the island, they are all mysteriously murdered one by one, in a manner paralleling, inexorably and sometimes grotesquely, the old nursery rhyme, "Ten Little Niggers". The UK edition retailed at seven shillings and sixpence (7 ⁄ 6) and the US edition at $2.00. The novel has also been published and filmed under the title Ten Little Indians.
It 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 (Publications International lists it as 7th best-selling). It has been adapted into several plays, films, and a video game.
