The Wolfen (1978), the debut novel by Whitley Strieber, tells the story of two police detectives in New York City who, while investigating the violent deaths of two policemen in a junk yard, discover that a pack of intelligent and savage wolf-like creatures are stalking the city. These predators are not werewolves, as they are a separate race of intelligent beings descended from wolves that live secretly alongside mankind. The Native American tribes of the northeast, having known of their existence for centuries, refer to the Wolfen as the true First Nation ("they might be gods").
