I absolutely hated this book. It was recommended to me via some list of the "best true crime books"....I don't know who came up with that list. Several of the books on the list that I wound up reading were no good. This book jumped around so much that it made it hard to follow. It was also extremely boring. It seemed filled with her own personal opinions and dislike for behavioral science. It had letters and and news interviews in it, but it was just not nearly as insightful as one would imagine. I would never suggest this book to anyone. It was just awful. I'm glad I gave it away.
