Summary: Lestrade asks for Sherlock's help on one of the most baffling cases of either of their careers. And each new piece of information serves only to make it more confusing as they run headlong into a world neither of them knew existed.
Spoilers: All of the HP books. Sherlock up to season 2, pre-Reichenbach, post-Hound.

**IMPORTANT AUTHOR'S NOTE**

All HP movie affectations are hereby discarded (for example, house crests on school robes). This fic is book-verse only.

More than that, unless something is actually in the books, I don’t count it as fully canon. Any JKR interviews or any other extra-canonical information I only accept if I like it. The one thing that is sort of in the books which I ignore is that I do not really hold with having fixed dates for the Harry Potter stories, whatever Nearly-Headless Nick’s stupid death-day cake might say. So get all of that out of your heads. It doesn’t affect the story all that much, but you may assume that the whole “the Battle of Hogwarts happened on May 2, 1998 precisely” bit is thoroughly ignored. And any reviews to the tune of same will be referred to this author’s note.
