Sherlock Holmes Fic Finding Community

So I remembered this fic from the old kinkmeme (sherlockkink). I think it was called The Contract, and it was a multipart but never-finished fill for an arranged marriage prompt. And it may have disappeared forever from the Internet, but on the off chance that it is available somewhere, I really would like to read it again.

It was set in the Victorian era, but with some alternate history things about the British upper classes having developed a sort of institutionalised version of Greek pedagogical eros that combined with really only needing one son to continue the family line and devolved into (often creepy and exploitative) mandatory arranged relationships for younger sons. From what I remember, the author put a lot of thought into how the legal system, courtship traditions, and fashions would work within the society.

And it was super-creepy. Moriarty had not-so-secretly had his eye on Holmes for a few years (long before such attention would be considered appropriate even in-universe) and convinced Holmes's father (who is deathly ill) that the best way to provide for his two sons is for him to designate in his will that Sherlock be married to Moriarty. The rest of the fic was Holmes, Watson, and Mycroft trying (unsuccessfully, thus far) to contest the legality of the change and Moriarty planning all of the devious things he's going to do once he has Holmes in his clutches.

If anyone remembers it and/or knows if the author ever reposted it somewhere else (or if you are the author and I can persuade you to repost it), that would be much appreciated!!

I'm looking for a M/M fic I read shortly after A Game of Shadows came out. It followed Moriarty and Moran through their first meeting until just before Reichenbach, and I believe I read it on either LJ or tumblr. The main thing I remember was, after Moriarty decides to hire Moran, the colonel (not yet realizing the extent of Moriarty's activities and wondering why a mathematician would hire him) makes a comment about how "those equations are tricky bastards" or some such thing. And Moran pictures himself taking notes at Moriarty's lectures.

There are a lot of references to mathematics and Moran trying to understand how Moriarty works. And it was awesome, and one of the first AGoS fics I saw. Sadly, however, I forgot to bookmark it. Anyone else remember it?  Thanks!
