Megan tried really hard not to laugh at Melinda's confusion, not because she thought her stupid, but because it was an odd question to her. She should have expected that the girl wouldn't have known the shop. It may be one of the poshest shops in London, though clearly completely unknown to certain parts of the population. At her question, however, Megan shook her head. "It's in Kensington," Megan explained as if that would explain everything. "Erm. Muggle London, it's a muggle shop. Really massive."
