I've never seen Deadwood, and I am lol'ing all over the place at the idea of Jim as a cowboy. I haven't thought this through as an AU week idea bc I was originally just going to fic it at some point. Jim would be a Jules Vern-era scientist probs sent over from the Royal Society with some experiment, but really there to spy on Sherlock/set up some crime whatever, probably with his pet sniper in tow.

But that was only ever a very vague thing, so I can adjust him to fit into anything people want to do.
