This is the first book I have read by this author. I really enjoyed the setting; Glacier National Park. In the story, Monty Harris, a park employee is given the task of trying to solve what may possibly be two murders which appeared to happen a few days apart. One of the deceased, "Wolfie" Sedgewick, was a wolverine researcher and had been live trapping wolverines (tranquilized, of course) to determine their part in the park's ecosystem. Apparently, the powers that be were considering putting the animal on the endangered species list. Paul, or Wolfie, was found dead as if he fell off a steep cliff which he had been to hundreds of times. When Monty Harris goes to investigate, a few hundred yards away, he finds the body of Mark Phillips, a cartographer, and it appeared that Phillips had died before Wolfie had (same scenario; a fall off the cliff in the same general area). Monty finds it a stretch to believe that two experienced hikers would have fallen to their deaths so close to each other and within a few days, so he starts investigating the two men's associates and friends. Monty's own brother, Adam, becomes a suspect briefly, because as a teen, he was doing drugs and committing crimes, etc. Monty had not talked to him in some time, but he remembered that the brothers' father sent Adam to a corrective Academy in the park as a last resort. (The father is an alcoholic, and the boys' mother was a depressive paranoid schizophrenic, so the had a very unstable upbringing). However, Monty finds out from the former owners of the Academy and others that the school was plagued by counselors who used very questionable actions as discipline, and that some of the students had been sexually assaulted. At the time, Mark Phillips, the cartographer, was working as a counselor at the Academy. Obviously, that is one piece of the puzzle. I thought the book well written, and I am going to make it a point to read the author's first book as well as the two she has written after "Mortal Fall."
