The Custer Wolf was a renegade that ravaged the territory in and around South Dakota causing up to $25,000 worth of damage a year. The rare mutant killed meaninglessly and mercilessly, sometimes just mutilating his victims and leaving them to die. It's a rare writer who can turn this kind of killer into the hero of a book but that is exactly what Mr. Caras has done in what he calls a ""fictionalized biography"" form. He gives you all the details, from Lobo's birth to his violent death, and manages to work in an immense amount of incidental information about other wild life. It's an engrossing walk on the wild side.
