Wolfgang Aldous Regnum has been turned into a werewolf, pressed into the service of an ancient orgnaization, and forced to become a Detective in the Richmond Police Department; all within the last two years. Now Wolf must navigate the world of Vampires, werewolves and monsters, living undetected among the humans.

Adding to his otherworldly problems, Wolf has been given his first murder investigation for the Police Department. A woman has been bludgeoned to death and her only son, Isaac is now orphaned. Seemingly a random killing at first until another victim is discovered.

As the pressure to make something happens with either case begins to take its toll, Wolf has little choice but to accept an offer of help from one of the most powerful Vampires in the city. Wolf will soon learn that it takes a killer to catch a killer.
