Flash back to the summer of 1964. Walt and his pal Henry Standing Bear, whose football careers at the University of Southern California recently came to an end, have enlisted in the military with the expectation that they will be sent to Vietnam. Their plan is to drive cross country to their assigned training facilities, but they have barely made it to Arizona when Walt’s truck runs off the road, stranding them in the small desert town of Bone Valley.
The town, they soon find, is as unwelcoming as its name. Get out as soon as you can, they are repeatedly told. Sometimes it’s a warning, sometimes a threat. Clearly something is wrong here, and Walt, already demonstrating the courage and persistence of a future sheriff, can’t let go of the mystery.
Meanwhile, back in the present, Longmire is under investigation for a fatal shooting recounted in The Longmire Defense, last year’s installment of the series. The victim was a member of a wealthy and politically powerful family, which is now out for vengeance.
The author moves smoothly between the two time periods, keeping both stories moving at a crisp pace. The old story is the more suspenseful one involving, among other things, murderous drug smugglers, a former judge who runs Bone Valley like a dictator, and a dark secret about the incarceration camps of Japanese Americans during World War II that had once operated nearby.
