Skinwalkers
Tony Hillerman
 When an unknown assailant tries to kill Officer Jim Chee by firing a shotgun into his trailer, and three other people are found murdered in different locations around the Navajo reservation, Chee and Lieutenant Joe Leaphorn of the Navajo Tribal Police find few motives or clues except for small pieces of bone found in the bodies and in the shotgun shells used in the attempt on Chee. This leads them to conclude that the assailants and victims were involved with Navajo witchcraft, whose practitioners are called Skin-walkers. Leaphorn, a secular Navajo, rejects witchcraft as hateful superstition that has no place in Navajo mythology, but Chee, a practicing yataalii or medicine man, does not dismiss it so easily. Solving the cases requires them to find a balance between Navajo folklore and Western inductive reasoning, and to risk their lives to track down a killer before he gets to them first.
