Harry Potter AU

[chaos-walking.livejournal.com]

Okay, you guys. I'm looking for a BBC!Sherlock fic set in the Harry Potter Universe. John is a Hufflepuff, Sherlock a Slytherin. John's mum is a muggle and sort of.... unstable, maybe? Harry's a Gryffindor. I can't remember how Sherlock and John became friends, but once they do, Sherlock spends the majority of his time in the Hufflepuff common room. Moriarty is a fellow student who seems sweet. John is rather fond of him. I'm afraid that's all I've got. Any ideas?
