"Yes, this is where the Mindhunter series came from. Diving into the politics of creating the serial crime unit is interesting. All the techniques and suspect profiles to catch serial killers were developed by this unit and largely led by one man: John Douglas. He answers questions people often ask: why did this killer do what they did? He can also often tell you why the killer killed in a certain way. It's fascinating to think that this man is still alive. These techniques were developed recently with the aim of catching a killer before they kill again.

Recommended for: Any true crime nerd who likes a good psychological deep dive. There is a series of books for the truly dedicated."
