Lucifer Hill is not your typical New York detective, for a while he had tried to be a Priest, and before that he was imprisoned in Hell. Now in the NYPD he is called with his acerbic partner James Burke to investigate the death of a Priest whose body has just washed up on the East River. When signs point to kidnapping and starvation Burke and Hill suspect that something far worse is happening and when within a short time another Priest and a high profile Cardinal are brutally murdered their fears fast become a reality, and the ritualistic nature of the killings hints that this serial killer is only getting started. Unfortunately one of the victims happened to grow up with the head of the Manhattan mob and the Capo di Capo does not take kindly to the murder of his long-time friend and confidante. He hires an assassin known only to the NYPD as Angel, a lady who brings troubles of her own in her wake, and who has a complicated past with Detective Lucifer Hill. Now, caught between a private military contractor and a mob war brewing behind the scenes Hill and Burke are in a race against time to bring the killer to justice before a bloodbath spills onto the streets of Manhattan. And hopefully before the demons of the past can twist the world into a nightmare around Lucifer.
