By John Douglas and Mark Olshaker. “Unlocking the Secrets of Serial Killers and Predators with the FBI’s Original Mindhunter.” The 2019 outing from "The FBI's pioneer of criminal profiling" Douglas and his trusty co-author "explores the lives and crimes of four of the most disturbing killers Douglas has confronted." I have found diminishing returns with "Dougshaker" after The Cases That Haunt Us and decided Law & Disorder was the end of it -- but true-crime bookstagram seemed to like this one.
This paperback is in nice shape: minor edgewear and a price sticker on the back, but sits straight, uncracked spine, clean inside.
