I like the new PBS modern Sherlock take on the character. Espically the episode, A Study In Pink.
It's a BBC show, in reality. Even if PBS did air it. Get it right!
Have you checked out the new BBC Sherlock series starting Benedict Cumberbatch and Martin Freeman? If not, get on Netflix and check it out now!
There ya go.

I actually created a Wild Sprite based on Holmes once (accidentally compiled by a Wild Technomancer who was a Media Junkie), though sadly that group dissolved before I had a chance to introduce it. It was a fun character to plan for, though. Writing Holmes well is hard to do.
Also, your GM is gonna HATE you.

Either that or ignore you. If writing Holmes is hard, GMing for him is twice as hard - your GM will have to think of all sorts of tiny clues to leave you and only you, and will have to create (more obvious and less accurate) red herrings to throw off other investigators. For
every scene in which you could make a perception check.
