The Red Hill - Penny David

A killer who can't be stopped. A request that can't be refused. In 1482 the Englishman Thomas Berrington is living in the last remnants of Moorish Spain. A physician, he is an unwilling friend to the most powerful man in the kingdom. When bodies start to turn up, each showing the marks of a savage attack, Thomas is asked to investigate. When one of the Sultan's wives is brutally murdered, what begins as a reluctant task turns into a fight for survival. Together with the eunuch Jorge, Thomas attempts to hunt down the killer before they become his next victims. Except nothing is as it seems-friends turn into enemies and enemies into friends. Thomas's investigation lays bare the secrets of the Red Hill and the people who inhabit it. His discoveries culminate in a battle not only for his own life, but for the lives of those he loves.
