I started out watching the TV series a few years ago and loved it so I had to check out the books.  This is the first one and it was great!  And not the exact same story as the episode on TV so don't worry about that.  Walt Longmire is the sheriff, Vic and Ferg are deputies, Henry Standing Bear is Walt's oldest friend and owner of a local bar.  He is also Walt's best aide dealing with the Cheyenne Nation on the near-by reservation.  This story is about finding the dead body of one of 4 boys convicted of assaulting a somewhat disabled Cheyenne girl.  Walt's been a widower for 4 years and is reluctantly stepping back into the romance game, dealing with a dead body of a young man nobody liked and who killed him, local politics.  It's the perfect picture of a small town in a western state, just like where I live.  Loved it!
