This is the best of the half dozen Thurlo novels I've read. Ellen Clah, head of the Navajo Reservation Major Crimes Unit, must find out who killed Jimmy Blacksheep, a Navajo national guardsman, who was on his way home from serving in Iraq. The rental car he was driving is missing. The obvious suspects are a car-jacking ring that has been operating on the Rez for some time. Clah, however, quickly decides that Blacksheep's murder is not simply a botched car-jacking.
MOURNING DOVE is more purely a police procedural than the other Clah mysteries I've read. Navajo life and traditions form the background rather than the foreground of this story. Clah's latest family problems are woven smoothly into the non-stop police action. In addition to the tribal police, the Farmington PD, the county sheriff's office, the FBI, the ATF, the CIA, and the US Army CID are drawn into the widening investigation. One wishes those agencies worked as well together in the real world as they do in this Thurlo novel.
