Last of the series so far, and what feels like the end of an arc with one of the two co-leads finishing her probationary period at the FBI.

A couple of volumes ago we had a mystery with a decidedly science fictional resolution (which has had no discernable ongoing effect on the narrative; to my surprise this series remains determinedly self-contained). This time we get a supernatural mystery, so it seems any kind of solution is valid here. At the beginning I was hoping we were getting a monster story and I don't think this really counts. Perhaps next time. Surely New Mexico must have some kind of forgotten hibernating reptile or nest of venomous pterosaurs up in the mountains that people might stumble onto.

My remarks from the prior volumes continue to hold. Clean, functional writing. Short chapters, lots of cliffhangers. The kind of book that flies by very fast. I will be reading more of them but I would hesitate to recommend them.
