numb3rsficfind | Charlie Friends with Mafia

kira2127 posting in

Hello! I am trying to find a fic (90% certain I originally read it on ff.net, but it has been several years since I was active in this fandom) where Charlie is approached by an old friend who asks him to look into his daughter's death. I believe that he man thought the death, although it looked accidental or a hit and run, was actually the work of a serial killer b/c of similar cases on a timeline. The friend had approached Charlie b/c he knew about Charlie's find of the major serial killer.

Charlie ends up going to the east coast, and Don either goes with him or follows him out after b/c it turns out the friend was a member of a large mafia/mob family, and the DA and FBI wanted to keep tabs on him. Turns out Charlie had tutored several of the mafia's family members in college, and had become close friends with them. The fic ends why Charlie finding the killer, and then both him and Don go to family dinner with the mafia.

Any help would be appreciated! Thanks in advance!!!
