The Cold Dish (Walt Longmire, #1)

Walt Longmire, sheriff of Wyoming's Absaroka County, knows he's got trouble when Cody Pritchard is found dead. Two years earlier, Cody and three accomplices had been given suspended sentences for raping a Northern Cheyenne girl. Is someone seeking vengeance? Longmire faces one of the more volatile and challenging cases in his twenty-four years as sheriff and means to see that revenge, a dish that is best served cold, is never served at all.
