The West Indian wizards of Whitechapel sound just the thing, Padma. I'll search the library for a street map of London from the nineteenth century. I think Madame Pince showed me some old guides for travelers when I was doing a report on historical wizarding tourism economics. Maps of that sort are too fragile to bring to History Club, but if I find one she'll probably let me do duplication and enlargement charms on it, which is better because then we can levitate it and everyone can see it at once and it will be absolutely SNITCH.
