[TV Shows] The League of Gentlemen

I discovered The League of Gentlemen the other day, and I may or may not have become a fan. "May or may not" because it makes me D-colon face a lot, but its humor is dark, twisted, and surreal enough that it appeals to me. Also, I can never look at Mark Gatiss the same ever again.

Now, this next question is important - extremely important. It is a matter of life, death, the universe, and everything that ever has been, is, and will be imagined:

Does anybody know of any good Sherlock/League of Gentlemen crossover fic?

I....I need fic of Sherlock and John going to Royston Vasey. It's consuming me from the brain outward.
