Ten strangers, apparently with little in common, are lured to an island mansion off the coast of Devon by the mysterious U.N.Owen. Over dinner, a record begins to play, and the voice of an unseen host accuses each person of hiding a guilty secret. That evening, former reckless driver Tony Marston is found murdered by a deadly dose of cyanide.

The tension escalates as the survivors realise the killer is not only among them but is preparing to strike again… and again…

Agatha Christie was born in Torquay in 1890 and became, quite simply, the best-selling novelist in history. Her first novel, The Mysterious Affair at Styles, written towards the end of the First World War, introduced us to Hercule Poirot, who was to become the most popular detective in crime fiction since Sherlock Holmes. She is known throughout the world as the Queen of Crime. Her books have sold over a billion copies in the English language and another billion in over 100 foreign languages. She is the author of 80 crime novels and short story collections, 19 plays, and six novels under the name of Mary Westmacott.
