It was so good, I bought it about a week ago and I've read it all like 3 times! It has all my favourite serial killers and even some new and interesting ones! Thank you

I read this book a while ago and honestly it's not for the faint hearted, it goes into detail about the most horrific crimes in history, looking at serial killers backgrounds and going into the detail about how they killed their victims. if you are interested in stuff like this then I recommend it.
