Another likeable outing in this series, and I continue to enjoy the mix of forensic science and actual crime. It feels a little less thriller-like than the other two I've read, though - not that I'm complaining, I'm just raising it as a point of interest. No-one's attacking Scarpetta here, unless they're attacking her reputation. It's more a straight hunting down of clues for her, while other people confront the suspects. The one time she does opt for confrontation, she chickens out before actually doing it, and I liked that. After all, she's a doctor, not a detective, so potentially facing up to a serial killer should terrify her. She should see it as a terrible idea and change her mind and leave it to people who are either more expert or more stupid than she is. If I'd managed to stumble across a serial killer in the course of my day I'd be walking the other way as well. I guess what I'm saying is that there's less of a sense of creepy danger here, although there's still just enough to scrape a place on my thriller shelf. More entertaining for me is the fun little science twist at the end.
