The Lady Laughs

Question: anybody have really really good recs on novels with, by or about serial killers? Movies also acceptable. Will be renting Manhunter later this month. Bonus points if there's "if you stare into the abyss" angst from the person hunting the murderer.

(I'm asking for raven-verse. Trying to get into the killer's head a little.)
