A selection of mysteries, some light-hearted, some romantic, some very deadly... 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.
