A New Start

Fiercely intelligent eyes scanned the shelves around him, looking for a book he hadn't read before; letting the atmosphere of the library wash over him and relax his tense muscles. To seven year old Harry Potter the library was more of a home than the Dursleys house could ever be, for it was a place that his family would never enter. There was no Uncle Vernon and Dudley to hurt him and no Aunt Petunia to force him to cook a dinner he could never eat. The only reason he could have his own clothes and was fed once a day was because Harry had used their own fears against them: the neighbours. He had logically pointed out (politely of course to not warrant the wrath of Uncle Vernon) that if they saw him half starved, wearing clothes too large for him, there would be talk. However, no amount of logical talk could stop Uncle Vernon from using his belt after a night at the pub.

The library had tall wooden shelves all lined up, their paint peeling and decaying as they age. It had many different sections (like most did) and there was a children's section in the corner, all bright colours and squishy bean bags. The books, some new and others old, were his only friends and even if Dudley hadn't chased them away, Harry wouldn't want to associate with them; he had found other children to be incredibly dull.

Harry was about to give up and go ask the librarian if she was ordering anything new, and if she wasn't he would use his innocent pleading look to get her to do so, when something caught his eye. It was a small black book tucked out of sight between two others. When Harry carefully pulled it out, mindful of the crumbling cover, Harry saw the title The Art of Deduction which lay in curly blue writing in the middle of the black cover.

Sitting down in the closest chair, with the thought that he would not be bothering the librarian after all. Harry began to read avidly. Over the following months the young boy practiced, using the instructions that were written and slowly began to uncover the secrets of Privet Drive. While observing the people around him Harry saw that Uncle Vernon was having an affair with his secretary, for he had faint smudges of lipstick that wasn't Aunt Petunia's on his lips. It must have been his secretary for anyone in a lower position wouldn't risk their job and anyone in a higher position wouldn't go near a man like Uncle Vernon and so it was a secretary, trying to win favour from her boss. However, after fully mastering the art of Deduction, life on Privet Drive became boring once more, with nothing left to deduce on the suburban street. Well, that was until the scream and it was after that, that things began to change…

Sorry for the short chapter they will be longer soon. Reviews will be much appreciated
