In this classic British standalone mystery by Agatha Christie, eight people are invited to a mansion on an island near the coast of Devon, England. They are greeted by two staff, who tell them that the host has not arrived but has left instructions. One by one, they are murdered like the characters in the nursery rhyme, Ten Little Indians.
