Becks’s Reviews > Whoever Fights Monsters: My Twenty Years Tracking Serial Killers for the FBI > Status Update

I decided to purchase this book after watching Mindhunter on Netflix. Mindhunter is loosely based on the work of FBI Agent and author Robert K Ressler. I find it so fascinating how agents like Ressler and the BSU produced research and profiles that lead to the imprisonment of many horrific killers.
