It’s so good. If you saw Mindhunter the TV show, this is the book behind that story. If you like to understand the minds that both commit crimes and the ones who solves them, this is the book for you. The narrator was a bit slow for my taste, so I speed it up ever so slightly and it became and enjoyable listening experience. I rarely reread any book, but in this case, I might listen again as there are so many interesting facts in this book that I don’t think I got every one on the first go. It also have the stories of most of the infamous serial killers we know, but told from someone who got to talk to them. And it left me with the somewhat chilling understanding that serial killers are both monsters and humans.
