So it's been...probably too many years since I've played this fellow. I got to reading his profile for an old comm and welp. Here I am, whoring him out.
Sherlock Holmes, in the journal there is a lovely AU history in which he is a vampire (as told through one of the old stories and tweaked to fit) and I would love some sort of reincarnation line, or even just an unexplained infatuation, or something of the sort (if you've got some idea in mind) in the more modern setting. John Watson, Irene Adler, Moriarty, Greg (yes Greg), Molly (who would need some discussion) or some well planned OC who preferably looks suspiciously like one of the mentioned characters.
Alternatively, I'm always up for some fix-its, continuations from BBC Sherlock or the Movies or something completely made up in Book verse with a strong preference for BBC adaptations if only for the modern aspect. I tend to forget little details when playing in a "past" setting.
I'm also happy to claim or share side characters as scenes require. If it's your style, I may know a gpsl I'd be willing to drop them into as well (even on the vampire spectrum).
