Here is the famous first case that launched the legendary career of Hercule Poirot and his ingenious creator Agatha Christie, now the most popular mystery writer of all time, as well as the world's best-selling author (over two billion copies of her books are in print). With The Mysterious Affair at Styles, Agatha Christie's cerebral and eccentric Belgian detective steps out of retirement and into the limelight of a classic mystery.Styles Court is a magnificent English manor house owned by a rich, strong-willed matron who, to the dismay of her stepson, has recently married a fortune hunter. The scene is set for death by violence. The murder of the mistress of Styles Court is so baffling, so cleverly-plotted, that it challenges even the skill of Hercule Poirot, notwithstanding the legions of tiny gray cells that take residence in his ever-so-fertile mind.
