Why Watson's Injury Changed Place Fic Search

[hanopycanopy.livejournal.com]

Hey guys, I'm looking for a fanfiction I read awhile back so I can share it with my friend. I believe in it someone insulted Watson for being a bad writer because he couldn't even keep straight where his injury was -- and it went on to have Holmes recounting a time when some bad guy used the injury against him. So he suggests that Watson change the place where his injury is in his stories. Sorry, my memory is a little vague.

Any help is appreciated! Thanks a lot.
