The Baker Street Irregulars
For some time now, I have been hoping to find a good Sherlock BBC or Sherlock Holmes PSL. (For the latter, I would be comfortable operating in either the book-verse or the new movie-verse, though I am also vaguely familiar with Basil Rathbone's stint as the world's only consulting detective. But you need not be familiar with both to drop me a line.) It's my preference to play Sherlock, since his neuroses have a lot of overlap with my own, but I wouldn't say no to giving John Watson a try if a good offer came along.
I'm not particular about the nature of the line, or when it begins. Ideally, I would like plot to be at least a fairly significant component (I would be willing to do most of the legwork, if that isn't your thing,) but I'm very open to suggestions, and not very picky.
