Retirement does not agree with former lieutenant Thomas Mullin. So when he receives a whiskey-stained letter detailing the disappearance of his friend's daughter Abby, he jumps on the first train to Arizona. Folks around town think Abby has gone back to the reservation where she was raised, yet the more Mullin investigates, the more suspicious he becomes. But even his agile mind and gift for deduction can't prepare him for the wild legends of the Papagos or the terrifying truth of what's really in store for Abby.
