Not since Partner in Crime have New York Times bestselling author J. A. Jance's beloved series characters shared a stage. But now, in a pair of cases that cross state lines, Beaumont and Brady are back! Seattle investigator J. P. Beaumont is working a series of murders in which six young women have been wrapped in tarps, doused with gasoline, and set on fire. Their charred remains have been creating a grisly pattern of death across western Washington. At the same time, in the Arizona desert, Cochise County sheriff Joanna Brady is looking into a homicide in which the elderly caretaker of an ATV park was run over and left to die. Was he a victim of some kind of turf warfare-or possibly something more sinister? Then a breakthrough in Beaumont's case leads him into Brady's jurisdiction. When the two met on a joint investigation years earlier, sparks flew. But here, as the threads of their 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. Except this time it's not just their own lives that are in danger but those of the people closest to them as well.
