Detective Ryan O'Clery agrees to meet a noted historian who claims to have information about his ancestors. But when he arrives, he finds she has been murdered and her computer stolen. His investigation will lead him back to 12th Century Ireland, to a time of Viking invaders and conquests, to an albino known as The White Devil of Dublin, and to a secret his family kept hidden for more than eight hundred years. It will also bring him face to face with a present-day serial killer intent on finishing the job he started.
