A killer who can't be stopped. A request that can't be refused.
1482: Granada, Andalusia. 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. Bodies are discovered, each showing the marks of a savage attack, and 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.
