What was the original UK title of Agatha Christie's novel now known as 'And Then There Were None'?

The original UK title of Agatha Christie's novel now known as And Then There Were None was Ten Little Niggers. It was the title used for the first British edition, published by Collins Crime Club in November 1939.

The title came from the nursery rhyme that structures the novel's plot, along with the names of the island and the ten figurines. The wording was already considered racially offensive in the United States, so the first American edition, published in January 1940, used And Then There Were None instead. American editions also altered related references in the text.

The British title remained in use for decades, despite its increasingly unacceptable language. A 1963 Fontana paperback continued to use it, while a 1985 reprint adopted And Then There Were None as the standard UK title. Some editions also used Ten Little Indians, but that was an alternative title, particularly in the United States, not the novel's original UK title. The Christie estate now promotes the book internationally under its modern title.
