Wolfgang Aldous Regnum has been turned into a werewolf, pressed into the service of an ancient organization, 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 other worldly problems, Wolf is 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 happen 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.

Detective Wolf Regnum has been living two lives, one as a father and Police Detective for the Richmond Police Department, the other as a member of the Vigiles, an ancient organization with only one purpose, to watch the night. But when a scream shatters the darkness both his worlds collide and everyone he loves may well pay the price.

A girl, speaking a language he cannot understand is lost in the city, but someone is looking for her. That’s when Wolf must accept that vampires and werewolves are not the only monsters in the dark…there are humas as well, and when they invade his home to find her, threatening his son, and the family he is desperately trying to build Wolf must decide how far he is willing to go.
