Query: Ablow Rocks!

Ablow is one of the most prolific serial killer writers on the market today. His expertise in the field of forensic psychology is meticulously expressed in his writing. Most of the characters (both the protagonists and antagonists) are case studies in and of themselves. I highly recommend Ablow for the serial killer connoisseur. You wont be disappointed!
