Discover the real-life mystery surrounding the queen of crime herself: Agatha Christie. In this “audacious mystery…with thrilling results” ( The Guardian ), Andrew Wilson investigates Christie’s unexplained ten-day disappearance and offers his own gripping explanation, in which Christie is pulled into a riveting case of blackmail and murder. “I wouldn’t scream if I were you. Unless you want the whole world to learn about your husband and his mistress.” Agatha Christie is preparing to board a train, preoccupied with the devastating knowledge that her husband is having an affair. She feels a light touch on her back, causing her to lose her balance, then a sense of someone pulling her to safety from the rush of the incoming train. So begins a terrifying sequence of events—for her rescuer is no guardian angel, rather he is a blackmailer of the most insidious, manipulative kind. “You, Mrs. Christie, are going to commit a murder. But, before then, you are going to disappear.” Writing about murder is a far cry from committing a crime, and Agatha must use every ounce of her cleverness and resourcefulness to thwart an adversary determined to exploit her expertise and knowledge of the act of murder to kill on his behalf. In this tantalizing novel Andrew Wilson ingeniously explores Agatha Christie’s odd ten-day disappearance in 1926 and weaves an utterly compelling and convincing story around this still unsolved mystery involving the world’s bestselling novelist.
