Looking for BAMF Mycroft Fic

[lestrades-lady.livejournal.com]

Could have sworn I knew where to find this fic, but I guess I was wrong . . .almost certain it was on LJ *somewhere*. Maybe it's been removed, who knows? But I thought I'd see if y'all could help me out.

Sherlock, John, Lestrade and Mycroft are pinned down in a warehouse (I think) by the bad guys. John's trying to keep an eye on everyone and fight, too. Mycroft goes completely BAMF and takes out at least one of the villains. Afterwards, he's kind of shaky and John's really understanding and supportive. It was definitely a BBC fic.

Ring any bells? Or if y'all know of anything similar, I'll take it, too!
