While teaching a tracking class at a Search and Rescue conference in Iceland, Oregon State Trooper Gabriel Hawke discovers a body in a boiling mud pool. The body is the young man Hawke's class is tracking. Unable to walk away from the young man's death without helping to find the killer, Hawke follows the clues and discovers the young man had few enemies, and all of them have alibis. The killer is cunning like the fox, but Hawke is determined to solve the homicide before the conference attendees head home in five days.
