Disclaimer: I do not own Sherlock.
A/N: My first Sherlock fanfiction story! I will admit, it was a bit daunting to try and portray Sherlock's… unique… character, but I think I did alright. I haven't quite grasped the concept of a 'Mary Sue', but I don't think my OC is – whatever that is. And they're not going to hook up by the fifth chapter, because – let's face it – it's going to take more than a pretty face and some intelligent words for Sherlock to fall head over heels. And even when he does, it won't be sudden and it sure as heck won't be conventional.

PROLOGUE
"I'm sorry!"
A tall girl stormed down the stairs, her dark hair swaying with every hurried footstep. Her eyebrows were furrowed angrily, and her eyes were dark grey and thunderous. Her pale, freckled hand was grasping a handful of the skirt of her gray dress – so as not to trip. At the top of the staircase, a smaller girl appeared. Her tear-stained cheeks were flushed red and she was gasping for breath.
"Sissy, I'm sorry!" she cried. Her eyes and dress were of the same grey, and her curly hair of the same dark brown.
The taller girl, the dark-haired one, skipped the last three steps and landed nimbly on the balls of her feet. She whipped around and looked up at her younger sister.
"What?" she snapped waspishly.
"I'm sorry, really!" she knelt down, but did not descend from her place at the top step. There seemed to be some sort of invisible barrier – preventing her from walking down those few steps and comforting the taller girl. There was nothing she could do. The damage was irreparable. "I didn't mean to – I'll – I'll do your chores for a month, but please – "
"Chores?" the older girl laughed incredulously, mirthlessly. "You think I care about chores? You really are stuck in that – that bubble of yours, aren't you? You have no – no bloody idea – " she took a deep breath. "I can't take any more of this place."
Despite her words, she did not move. Neither did her sister. They stared at each other, one set of eyes filled with anger and the other with tears. There was a long stretch of silence, and neither seemed willing to break it.
Until the younger girl said, with a voice soft and barely audible from the crying, "Don't leave."
And that was enough. The taller girl shook her head – her chin only trembling a little – and turned on her heel.
The front door slammed a few moments later.
