Nashville PI Jackson Gamble has had all manner of clients and cases during his long career as a private investigator, but never a client like the one involving convicted triple-murderer Harvey Harris. Until recently a death-row inmate, and now dying of untreatable cancer, Harvey wants to see his daughter one more time before his time runs out. The search seems simple enough, but the girl has been missing ten years, and the case quickly goes into the weeds as Gamble's search takes him on a three-state chase that involves him with a beautiful woman, two murders, and a conclusion that even an experienced PI like Gamble never quite sees coming.
