Louise really missed the hidden room. It was tiny and didn't match the rest of the flat, but it was the only place in the world where someone (not even an underage witch or wizard) could do magic without anyone being able to trace it. She had combined the spells she invented herself with muggle technology. She was probably the safest witch in the world.

She had never been especially brave. The only brave thing she'd ever done was participating, if only briefly, in the battle of Hogwarts. What she had planned to do would require far more courage. And wit, she reminded herself. Nobody else, except maybe a few people, would be able to do what she had to do. This was the wrong time to be scared. Knowing that the Sorting Hat never actually considered placing her in Gryffindor, it was easy to feel scared. Making up for old mistakes was worth the fear. She had to force herself to continue forward. She walked past the Weasley's joke shop. A one-eared man with red hair was talking to a woman. Louise tapped her head with her wand, making herself able to hear all the noises that most people can't hear. She'd invented the spell herself. It was simple, but one of her favourites.

"So, Mrs. Finnigan", said George, "you want to keep your husband from setting the house on fire twice a week? Then you should try this new product, which will make the room and everything in it fireproof. The sales have been great so far this Christmas, this is the last box of FireStopper we have-"

Louise didn't have any time to think. She put the tip of her wand to the wall, muttering an incantation quickly. She crawled through the hole she had made in the wall. She found herself in a small room that wasn't actually a part of the store, and hurriedly repaired the wall. A baffled Martine Copplestone – now Martine Finnigan – just stood there, while George Weasley seemed far less surprised. Martine was a former Hufflepuff, known for her obsession with Wingardium Leviosa.

"Good evening, George and Martine. I'm sorry to interrupt, but-" Louise didn't know what to say. The bottle of FireStopper would make everything far easier for her when entering the ministry. She decided on passing the time with some polite conversation until she knew what to do.

"So, how's Seamus?" asked Louise. Martine seemed to be recovering from the shock, and looked rather pleased to see Louise.

"He's good. Actually, he just got promoted. The Ministry has been so busy recently, so when Potter was appointed Head of Auror office-"

"Harry Potter is Head of Auror Office?" Louise couldn't believe her ears. Potter was the youngest Head of Auror Office that the magical world has seen?
