Twelve tantalizing cases… the curious disappearance of Lord Listerdale; a newlywed's fear of her ex-fiance; a strange encounter on a train; a domestic murder investigation; a wild man's sudden personality change; a retired inspector's hunt for a murderess; a young woman's impersonation of a duchess; a necklace hidden in a basket of cherries; a mystery writer's arrest for murder; an astonishing marriage proposal; a soprano's hatred for a baritone; the case of the rajah's emerald.

All have one thing in common: the skilful hand of Agatha Christie.

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.
