C.P.C.A: The Criminal Population Containment Agency by THATmerlinguy
Fandoms: Dexter (TV), Original Work

Summary
Dexter Morgan is a blood splatter analyst for Miami Metro Police Department, the best one at that. Dexter Morgan is also the dark defender of Miami, a serial killer that hunts killers. The best one at that, too.
Alexei L. Novikov is a secret agent for a morally questionable agency, used to doing most of the job alone. And yet, is one of the best workers in the Agency.
Until they get forced to find a new agent for the Squad.Dexter pictured himself working alone until the end of his days, feeding his Moondancer. His dark passenger.
Alexei just wants to have a decent partner, and if stalking and begging for the blood guy to join them is enough to get that, then that’s what they’ll do.
NOTES: CPCA is for an original work, along with the original characters. But i wanted to make a Dexter/CPCA fic first because... well, i want to. Also, if the title of the chapter starts with a song reference it's going to focus a little bit more on the OC's, if it's a Dexter reference (series or novel) then it's focused on the Dexter characters.
Every chapter will have a song at the beginning or the end for you to listen to :)Series

Summary
Dexter Morgan hates funerals.
He doesn’t mind the black, the formal clothes—hell, he can admit that the free food is nice—but the rest? All the well-wishers and mourners with their hugs and their “I’m so sorry for your loss”s set his teeth on edge, and even his sister feels more like an alien today than she normally does.

Summary
Tyler Joseph lives by one code. Some would call him a murderer, but he would call it doing the world a favour. Murderers, rapists, and other horrible people that fall through the cracks of the justice system—you name it and he makes them disappear. It's not completely a secret though. Tyler's somewhat of a self-proclaimed journalist, and every time he kills, he makes sure to upload an entry to a website made specifically as an 'outlet for murderers'.
Joshua Dun, a homicide detective, also lives by a code. The code of justice. When he's assigned lead detective on the hottest task force, the Columbus Carver, he's determined to prove himself, and hopefully inspire others. This includes Tyler's younger brother, Zack, who looks up to Josh as a role model on the task force.
For Tyler, having a cop in the family means that he knows what and what not to do. It's perfect. However, things become complicated when Tyler begins to research the lead detective he hears so much about, only to find out that Detective Joshua Dun is not only awfully hard-working and determined, but also undeniably attractive.
But what happens when Tyler finds himself with thoughts (and some feelings), that he can't just kill?

Summary
Stephanie Brown is just a normal girl.
Well, as normal as you can be when your father is a bargain-bin supervillain and your mother is a recovering addict. Still, she’s managing. Good grades. Decent friends. An internship at the GCPD that’s going surprisingly well. And most importantly, none of her victims have caught the attention of the big, bad Batman or any of his little bird sidekicks.
Oh, right. Victims.
She probably should have led with that. Stephanie’s a serial killer. But relax, she only does it occasionally, and only to the people who slip through the cracks. The ones too small for the Bat to notice or too smart to be caught. She’s doing Gotham a favor, really.
Everything was fine… until another serial killer started leaving messages.
For her.
