I have now read several of his books now and feel this one is the best one I have read. Joe given some cold cases to solve so he will not be babysitting a bunch of boy scouts meetimg on Navajo land. Included are a missing helicopter, take of am important individual, deaths of 2 Navajos and the man that tried to run over Joe. It takes place entirely on Navajo reservation so a lot of the Navajo way of life is explain. Joe’s priority is the man. He finds the car and the driver and large dog are missing. He stops at McGinnis’s store and learns about AIM some years ago. The problems are woven together nicely. On the way there are some twists and turns.
