A really twisted request

[cptnstag-xo-doe.livejournal.com]

So back when I was just getting into the fandom, I ran across this fic--a beautiful tear-jerker with a happy ending. It was on lj, and it was a fic about Anderson sexually assaulting Sherlock and then convincing himself he didn't do it. Donovan may have been in on it, or completely ignoring the signs. Eventual Johnlock (possibly) with maybe about ten chapters. Mycroft might sneak in at the end to kill Anderson and get Donovan transferred  The assault scene was in a multiple story building they were investigating, and everyone was gone. The two got into a fight (a fireplace might have been mentioned?) and end up horizontal, then Anderson loses his mind, basically. He also convinces Sherlock not to tell anybody what went down (several scenes where it so easily could have come out). There was definitely a scene where Donovan's all "what's wrong with freak?" and Anderson bullies him. Someone (John?) comes downstairs (at another crime scene) and asks what's going on. They're all like "nothing" even though its obviously something. Hope that's enough information.
Pleas help,
