Hard to rate a book like this really.
I did a 14-page PsyCrim profile on Edward Gein for my Forensic psychology class in May 2014. A PsyCrim profile is basically a in depth report written after intense research into a criminal's personal and criminal history. This particular book was one of my primary source materials for my report.
The book itself seems to be very well researched and written much like a story. There are quotes, legal documents, medical reports and anecdotal stories sprinkled throughout, as well as a section of photographs. To be honest it was endlessly fascinating to me from a psychological standpoint. As a human I was horrified by Gein's crimes but as a clinician it was educational to see the correlation between things I had learned in class and how they impacted a person and their actions.
I'll give this book 4 stars, but please realize it's not from a personal sense of enjoyment but from both an academic and clinical standpoint. It truly helped me draw a picture in my head that I was able to translate into report form in both written words and for an oral presentation.
I ended up with a A+ on my report and a deep sense of respect for people who muck about in the brains of psychotic people for a living.
