Have you seen the tv show "The Body Farm"? I did couple of years ago and previously had no idea that those places really exist. A body farm is a research facility where human decomposition is studied in a variety of settings in order to use the results for solving crimes, like timing and circumstances of death. I'm mentioning this because the story at the beginning reminded me of this tv show. But as the story continued, it was very different from it, it became a hell-of-a-thriller itself.
D-r David Hunter is British anthropologist visiting his friend and mentor working on the famous Body Farm in US. But in the meantime, a murder happens under very unusual circumstances. Male body is found naked in a chalet, tortured. D-r Hunter's mentor works on the case and asks him to assist. Another body appears and it becomes obvious that it is serial killer we're talking about, and the chase of cat and mouse begins. But who's the cat, and who plays the role of the mouse?
