This was the first book of Nicci French's that I have read. Starts slowly, but builds up to a "can't put it down" pace, which leads up to a very surprising climax. As someone who is more accustomed to male oriented plots, which can become cliched and stale, I found this plot, which is very much from the feminine perspective, especially the climax, a refreshing change. Suffice to say it was enough for me to order more Nicci French books from Amazon. Psychological thriller is exactly the right term for this book.
