A Community for the 2010 BBC tv series Sherlock

Just in case you, like me, have been under a fannish rock for five days and haven't heard:

SHERLOCK TO RETURN FOR SECOND SERIES.

It's all a bit vaporware, as Moffat is obviously also doing Who and the shooting schedule depends on that.  Still, we have a second series and sherlockbbc has 23 subscribers, so I think this calls for a small party post.  Leave fic prompts, macros, and joy in the comments!
