"Enemies unseen... Fears unspoken... A dark wind has entered his soul"
Navajo Tribal Police Sgt. Jim Chee seems to be batting zero; so far, he has not been able to solve a series of seemingly unrelated crimes. In an area, that was joint use land between the Navaho and the Hopi (now Hopi) Sgt Jim Chee is given the task of finding the vandal that keeps destroying a windmill placed there to make Hopi life easer. He hears an airplane landing in the dark of night with no lights. The plane crashes and leaves a dying pilot. Also a dead man sitting up against a rock with a note in his hand saying if you want it back contact...
Sgt Chee is told that it is probably drugs and federal jurisdiction. Chee is not supposed to go anywhere near or have anything to do with the case. He has his own problems with the mill, a missing thief, and a mysterious ritual death. Naturally, he listens, and cannot help it if they overlap.
One of the reasons for reading Hillerman's books maybe more important than the overlying mystery is the descriptions of the area and the Ways of the Navaho and Hopi. Hillerman suggests you also read "The Book of the Hopi" by Frank Waters.
Not as intricate as the book but still fun is the movie "Dark Wind" (Lou Diamond Phillips as Officer Jim Chee, Fred Ward as Lieutenant Joe Leaphorn)
