Okay, starting to think I've imagined a fic! It's Destiel, Dean is a cop or a Fed, chasing a case. Cas starts as a suspect, but turns out to be chasing the same killer. The killer is ritualistic, if I remember, leaving clues as they go in Enochian, maybe? Now, here's where I think I'm maybe crazy, because I *also* think it was A/B/O, but I might be combining fics in my head so maybe it's not. I know it's sketchy but I hope you can help! I feel like I'm losing my mind lol
I’m sorry nonnie I was unable to find this in the allotted time. Do you remember if anyone else was in the fic? It is possible to mix several fics together but I don’t think you imagined the fic if it makes you feel better. There are a lot of serial killer au’s and a lot of destiel fics that have been taken down to be made into novels or just for editing purposes. Hopefully someone recognizes this one and can point us to it.
For any followers if this fic sounds familiar please add to the post so we can find this fic for nonnie
