[Fight Club/Se7en/Red Dragon Tyler/Jack | David/Will] Criminal Psychology

Reposted fic - 2012 - Abandoned * This is a crossover I've always wanted to write, but for David and Will, it's obviously a crack pairing. Sorry, Detective and Doctor. (What?) * The story takes place while Tyler's fight club is evolving into the grand destruction plan, and our two little detectives (not really) haven't yet received the case that will change their respective fates. * So it's a battle of wits between a police couple and a criminal couple? (Don't believe it.) * Rating: PG (Maybe NC-17?) * There will definitely be OOC
