As he watches, her body drifts below the water's surface, forever altered. Before he disposes of each victim, he takes a trophy. It's a sign of his power, and a warning. In Grizzly Falls, Montana, Detectives Alvarez and Pescoli are struggling with a new commander and a department in the midst of upheaval. It's the worst possible time for a homicide. A body has been found, missing a finger. Alvarez hopes this means a murderer with a personal grudge, not a madman, until a second body turns up.
