Stardust

[saddest-laugh.livejournal.com]

At one time, I read a Sherlock/Stardust crossover featuring John as the star, not Sherlock. Sherlock goes over the wall not for love, but for a bet. I bookmarked it so I could go back for updates, but since then I had to wipe my computer and lost all of my bookmarks. Does anyone know of such a story? I would really appreciate being able to go back and finish it.
