Seattle investigator J.P. Beaumont is working on a series of murders in which six young women have been wrapped in tarps, doused with gasoline and set on fire. In the Arizona desert, Cochise County sheriff Joanna Brady is looking into a homicide in which the elderly caretaker park was run over and left to die, leaving behind his dog. As the threads of their two seemingly separate cases wind together, Beaumont and Brady must put aside echoes of their shared past as they are once again drawn into an orbit of deception.
