And then there were none (HarperCollins Publishers)

Solving the world's most puzzling mystery novel just got even more fiendish in this gorgeous new hardback collector's edition - with the final solution sealed in an envelope at the back of the book!

Can you crack all the clues and catch the killer before you unseal the ending? 'Agatha Christie's masterpiece' Spectator Ten strangers are lured to an island mansion on an isolated rock near the Devon coast.

Cut off from the mainland, with their generous hosts mysteriously absent, they are each accused of a terrible crime. When one of the party dies suddenly, the guests realise they may be harbouring a murderer among their number.

The ten strangers include a reckless playboy, a troubled doctor, a formidable judge, an uncouth detective, an unscrupulous mercenary, a religious spinster, two restless housekeepers, a highly decorated general and an anxious secretary.

As one żeby one they are picked off, the dwindling group must stay one step ahead of their deadly stalker. Who will survive? And who is the killer? And in every room hangs a copy of an ominous nursery rhyme, foreshadowing the awful fates of ten people doomed to die...

For the first time ever, this unique edition of Agatha Christie's masterpiece presents her story in a format that is entirely faithful to her original conception, with the final solution presented in a letter that can only be revealed once you have finished the story and discovered if you have solved the deadly puzzle correctly.
