This outing is quite the lively mystery set, per usual, in the rugged Wyoming wilderness. This time, Sheriff Longmire is called out by a relative of Walt's late wife to travel from Absaroka County to south central Wyoming . The relative is a postal inspector for the state but he needs Walt's anonymity in this region to sort of go undercover to investigate the disappearance of Blair McGowan, a postal worker responsible for the longest rural mail route in the United States that runs over three hundred miles across, around, and through the desolate Red Desert.
Walt poses as McGowan's replacement mail carrier, though the sheriff’s distinctive stature (six-foot-five) kind of undermines any real attempt at being secretive. Plus he does have a bit of a state wide reputation. No matter. Walt pursues this case, like all cases, earnestly by retracing McGowan’s route in her battered 1968 Travelall. On this lonely circuit, Walk is accompanied by Dog, his huge, but undeniably endearing canine companion. Their journey is littered with quirky encounters with the locals, curious clues left under painted rocks, confrontations with Blair’s odd/loser boyfriend and, most astonishingly, a cult, led by a has-been wannabe TV actor, hiding in the desert. Obviously, this cult quickly becomes the center of Walt's interest.
The book shows us just how comfortable Johnson and Longmire have become with each other. The narrative showcases Johnson’s trademark blend of wry humor, the colorful and dangerous Wyoming desert wrapped around a clever tale dotted with unrelenting suspense. Given the expanse of the Red Desert, Walt has to come to grips with modern technology - he gets his first cell phone. OK, an old flip phone - that he painstakingly attempts to learn. His 'relationship' with technology shows the classic Longmire charm and his stubborn, old-school grit that we devotees have grown to relish over twenty-one novels. While the main characters of the book really are Walt and Dog, we are still treated to the usual suspects in Walt's circle of support: his under-sheriff (and fiance) Vic Moretti, best friend Henry Standing Bear, secretary Ruby, the former sheriff Lucian Connally, and daughter Kady all make, for the purposes of this story, cameo appearances. The focus remains on Walt’s solitary investigation and Dog’s devoted assistance.
One of Johnson's gifts is his skill at presenting a sense of place. The desert's beauty as well as its dangers. And within this beautiful, if harsh, place Walt has to deal with fistfights, gun play, and an adrenaline-charged chase across the desert. Overall, Return to Sender is another standout entry for rookie and legacy fans alike, brimming with tension, heart, and the colorful cast that keeps us coming back to for our annual visits into Longmire’s world.
