I am SHERlocked

When two brothers and a sister were born, they forever changed the reputation the family name wore. Mycroft, a successful government official, was named as a control freak, one that enjoyed power. Sherlock, the world's only consulting detective, a self-proclaimed high-functioning sociopath. And Eurus, the most intelligent being in the world, the woman who murdered her brother's best friend and burned down their family mansion. All anybody knew was that all three siblings exhibited some sort of personality disorder. Nobody expected for any of the three to find somebody to love.

One brother found himself with a daughter to take care of, even though he loved nobody else. He couldn't help it. His sociopathic abilities were overtaken by the way his daughter looked at him, her eyes twinkling. The brother knew that he and his family had his share of enemies, and not enough friends to go around. When she is young, he gives her to a member of the police force, to help keep her identity hidden.

The Ministry originally focused their attention on the mad sister, until an enemy of a brother holds a threat over the magical community's heads.

Secrets have a way of finding their way around London, and for the girl, her last name only attracted attention. Despite his powerful deduction strategies, such a secret was unknown by Jim Moriarty.

Enter Colette "Kit" Holmes, a fourteen-year-old witch at Hogwarts School of Wizardry and Witchcraft.
