Novella-length recs

[m-lasha.livejournal.com]

I read the books as a teenager, but after watching the new Holmes movie, I must say I am hooked and want to read some good H/W fic.

So, are there any novella-length fiction (30,000+ words) that feature just the Holmes/Watson pairing from the '09 movie? No WIPs. Can be any rating, doesn't matter who is top/bottom. No rape or prostitution stories. I am looking for longer reads. TY.
