I actually enjoyed this book. It has everything a good thriller needs (morally ambiguous characters, good pacing, interesting twists) and nothing it doesn't need (gratuitous needless violence which is almost pornographic in its description; helpless/hapless victims hunted by an evil sociopath to gratify some weird pathology). Nor does that cliched forensic investigator solving it from behind his or her microscope or other unidentified piece of cutting edge technology. Fictional people die, they have to, it's a murder thriller, but it is interesting how it all fits together. Easily held my interest to the last page.
