The Dark Horse.
(Book)

Wade Barsad, a man with a dubious past, locked his wife Mary's horses in their barn and then burned it down. In return she shot him in the head six times - or so the story goes. Sheriff Walt Longmire doesn't believe Mary's confession is the truth, and he's determined to dig deeper. Posing as an insurance claims investigator, Walt goes undercover and soon discovers that the population of an entire town might have wanted Wade dead, including a beautiful Guatemalan bartender and a rancher with a taste for liquor but not so much for honesty. Interweaving classic noir sensibilities with contemporary themes of social justice, Craig Johnson's popular Walt Longmire mysteries transport readers to the sparse and rugged landscape of Wyoming. Featuring his signature sense of humor and his inimitable cast of characters, The Dark Horse will keep readers guessing, as Walt ventres into a town without pity to save a woman without hope. It's an unfriendly place - something that's fine with Longmire, who is looking for the truth, not friends.
