Zehn kleine Negerlein
Agatha Christie's novel "Ten Little Indians" (1939, originally "Ten Little Niggers", later changed again to "And Then There Were None") presented the concept of a mysterious killer preying on a group of strangers trapped at an isolated location (in this case, Indian Island). This was made into "And Then There Were None" (1945), directed by the French exile René Clair. Three more film versions, all titled "Ten Little Indians", were released in 1965, 1974, and 1989 along with the 1987 Russian film "Desyat Negrityat".
