Just One More Question
FBI profiler John Douglas is also interesting, even if he's a bit full of himself and not the greatest wordsmith. Roy Hazelwood is another profiler worth reading, if you can stomach it.
I found Douglas' last book Anyone You Want Me to Be, to be his best work to date. This might be because he didn't write it with Mark Olshaker (I may have gotten the spelling wrong). Douglas does seem to recap his career, and his importance to the FBI and Profiling in his earlier books. He keeps telling the story of when he nearly died tracking the "Green River Killer." However, I think some of that may be an attempt to make a book where you don't have to read his first (Mindhunters)to learn about his qualifications and his experiences.
The Cases That Haunt Us is a good read for any skeptics of conspiracy theories.
