This is the seventh book in the Leaphorn/Chee mystery series, I’m filling in books I didn’t have originally and it does not disappoint.
Jim Chee is investigating some unsolved and seemingly unrelated homicides that have happened around the reservation, then there is an attempt on his life. There is no evidence of a correlation, leading Leaphorn to consider come illegal activity Chee may be involved in.
Leaphorn is dealing with his wife’s health, dealing with Alzheimer’s disease, and needs surgery for a brain tumor.
Chee’s studies as a medicine man lead him to believe that a skinwalker, a mythical figure who can shape-shift into another man or animal, is involved. If a skinwalker can force a piece of bone into a person, the person will die unless he can kill the skinwalker first.
The correlation to the deaths comes back to a clinic and fraud. Stopping to avoid too many spoilers.
It is one of the more interesting books in the series.
