And Then There Were None is a quite different murder story to all other Christie novels. 10 people are invited to an island under the pretext of work but after arriving each one is revealed as a murderer. The story follows the rhyme 10 Little Indians and each of the guests are murdered according to the rhyme, until the last person discovers who is killing them. A dark, very different mystery but well watchable and will keep you guessing until the end. One of Agatha Christie's best novels.
