Killing For Sport: Inside the Mind of Serial Killers By Investigative Criminal Profiler Pat Brown. 2004.
I thought this book was very interesting. I also liked the author's style of writing. She is blunt & gets straight to the point. Like she says in her book "no fluff & no ego trips."
If you want to know about serial killers, how their mind works & facts about them. Read this book.
She does a very good job explaining how serial killers think & operate so about anyone can understand it. So if you like psychobabble, complex lingo, & other BS. You won't like the book.
