Open Season (Joe Pickett, Bk. 1)

Joe Pickett is the new game warden in Twelve Sleep, Wyoming, a town where nearly everyone hunts, and the game warden - especially one like Joe, who won't take bribes or look the other way - is always far from popular. When Joe finds a local hunting outfitter dead, splayed out on the woodpile behind his state-owned home, he takes it personally - and thrusts himself into a mystery that threatens the life and family he loves.
