If there is one thing that baker street doesn't need right now, it is Sherlock's daughter. Havoc in her own ways, Aaris Holmes is 18 and has already scared more than half of London away with the "freakish abilities" that she inherited from her father.
Although 'abilities' is to say the least. No. Aaris Holmes is an apple that shot from the tree, and fell right in ANOTHER NEIGHBORHOOD altogether. You see Aaris has an advantage. She not only took after her father, but also inherited the insane intelligence and learning abilities of her mother, Irene Adler, the only woman who was able to seduce Sherlock. What's more is that where Sherlock strives to solve cases, gets a kick out of catching murderers and hunting hounds, Aaris, is more of a master manipulator, causing just enough trouble to keep everyone on the edge. Like Sherlock, she doesn't have friends, or any kind of social life.
After she teaches herself how to handle guns and shoot, she shoots the neighbors' dog dead just because he was making too much noise, Sherlock can't decide whether his daughter is his little angel or a demon. Determined to discipline her, and make her live a normal life, something he never had himself, he sends her off to a posh boarding school.
Sherlock and John think it is for the best, but is it? She is after all, Sherlock's daughter.
