(HP) The Detective of Hogwarts

[Updated whenever the mood strikes. If you don't like the premise, you don't have to read it. There's no need to argue in the comments and ruin everyone else's mood. - 2021.09.08] He looked a lot like young Tom, but had far more love in his life than Tom ever did. - Albus Dumbledore Before the Chamber of Secrets incident, I didn't even know he existed in my house. But through his own unique method, the thing he called deduction, he made everyone marvel at the rigor of his reasoning. - Minerva McGonagall A fellow you can't help disliking. But no one expected him to be the first to step forward. - Harry Potter "I have two people in this world who love me more than anyone else. No matter how the world slanders me, they will never betray me." Standing in the middle of the Wizengamot courtroom, the boy fearlessly met the judges' cold stares. "This woman you insult at will and call a Mudblood is one of them. She's my mother. Wizards think they are superior to all other living things, and from childhood, they teach us that Muggles are ignorant and foolish while wizards are clever and brave. But I wonder how many of you here have learned anything about modern Muggle history? I think the situation wizards are in is a lot like that of a great East Asian nation that shut itself off from the world in modern times." Sherlock flicked the sheet of paper in his hand. "Like this piece of paper, written to me by a Muggle. I imagine everyone here is an elite of the magical world. Can any of you use any kind of magic to make the words written on this paper appear again?" - The not-so-serious blurb - 1L Voldemort: You've got nerve. If I had a son, I'd want him to be just like you. 2L Sirius Black: You've got nerve. I wish you were my son. 3L Biological Father: You little brat, I wonder who you take after!!!! Thread starter Sherlock: Did you two get something wrong?! I have absolutely nothing to do with either of you! The protagonist did not transmigrate. His mother is a transmigrator born into a Muggle family, and his father comes from a pure-blood family. He won't get any golden fingers apart from his detective skills. This is absolutely not a harem story! The author's values are impeccable! No Hogwarts house will be bashed. Premise: Detective adventure
