Chapter one
Sherlock sighed. It was the last lesson of term, and the pupils were about to flood in to his classroom at Hogwarts school of Witchcraft and Wizardry. He taught defence against the dark arts, a job often cited with bad luck. Sherlock called out. "Class, enter." The pupils filed in and took their seats. The lesson seemed to drag for everyone. Finally, it ended, and Sherlock gathered up his papers whilst his pupils ran from the classroom, whooping and cheering. In six weeks, he'd be teaching them all over again. Sherlock sighed. For now, at least, he had 6 weeks of undisturbed silence at his small home, to concentrate on his other passion- crime solving. "Muggles do have some awfully interesting trivia going on," he mused. After checking he hadn't left anything of note in his classroom, he locked up and retreated to his private rooms. After a small supper, he went to bed.
Sherlock work up bright and early the next morning, packed all of his clothes and belongings in his one, small case, and left for Hogsmeade station. The train journey was fairly uneventful, apart from excited students running up and down the length of the train. On the way back, Sherlock rang Lestrade. He worked at Scotland Yard police station, and was the officer Sherlock often helped out. It tended to only be in the school holidays, but if Lestrade desperately needed it, Sherlock would don his black suit, and apparate to London to assist him with a case in the dead of night. "Hello?" Sherlock said in a questioning voice. "Oh. Lestrade? Freak here for you." Donevan had answered the phone, and handed it straight to Lestrade. "Ah, hello Sherlock." "Good morning Lestrade." Sherlock used polite tones, desperate to be back in the game. "Anything urgent, or do I have time to go home first? My robes are a little... Conspicuous." Out of the seldom few people Sherlock knew outside of the Wizarding world, Lestrade was the only one who knew he was a wizard. "We've got nothing incredibly urgent at the moment, Sherlock. Pop down after you've got home and sorted yourself out." "Will do, thanks Lestrade." Sherlock then put the phone down. He could only take being polite for so long.
Sherlock pulled out his keys, and heard the familiar click as the key turned and unlocked his door. A necessary prop, in the muggle world, despite the fact he was rather efficient at non verbal spells and could of easily unlocked the door with a thought, he had to at least appear normal. Mrs Hudson greeted him at once. "Sherlock, dear!" she said warmly. "Mrs Hudson." A small smile played on Sherlock's lips as Mrs Hudson told him she had the tea ready for him for when he got home. Sherlock accepted the offer of tea, and sat and chatted with her for a while. Like the other muggles he knew, apart from Lestrade, of course, she thought he taught at a private muggle school out in the country. He finished his tea, and headed up to his flat.
Sherlock got out yet another key and opened the door to his flat. Everything was tidy, yet seemingly untouched. "Mrs Hudson has tidied," he thought to himself. He went straight to his desk, and turned his computer on. He didn't bother taking such gadgets to Hogwarts, as they wouldn't work anyway. For a wizard, Sherlock was quite savvy on the latest gadgets in the muggle world, and generally kept up to date. It was frustrating for Sherlock not to be able to use magic to assist him with his cases, but in some ways he relished it. He was able to gain an extra skill, by knowing a lot about science. Also, his magic did help, when there were those cases committed by criminal wizards.
When he was done on his computer, Sherlock went into his bedroom, changed from his long, black robes and hung them up in his wardrobe for the next six weeks, and then left his flat, ordered a taxi and left for Scotland Yard.
