An ancient mystery. A modern murder. Sir Augustus Wall, a horribly mutilated veteran of the Great War, has left Europe behind to open an antiquities shop in Cairo. But Europe's troubles follow him as a priceless inscription is stolen and those who know its secrets start turning up dead. Teaming up with Egyptology expert Moustafa Ghani, and Faisal, an irritating street urchin he just can't shake, Sir Wall must unravel an ancient secret and face his own dark past.
