Hello m'dears! Hope y'all like this one. Set between 'A Scandal in Belgravia' and 'The Hounds of the Baskervilles'. I have a deerstalker, which just so happened to A: have come from 221b itself and B: it's the same pattern as Sherlock's. Your argument is invalid.

Much love~ Beatrice Holmes

"Mycroft! There is no possible way you are looking after her, you'd drive her insane, you did enough of that when you were at home! Send her here immediately" Sherlock Holmes hung up angrily and flopped into his armchair.

"Should I even ask?" John muttered, wandering into the living room, a cup of tea in his hand. Sherlock grunted in reply. "What disaster have you caused now, broken his favourite action man? Nicked all his Smurfs?" John laughed at Sherlock's horrified expression. "We are going to have a new flatmate. I think." Sherlock muttered, his baritone voice barely audible. The doorbell rang, and for once, the great Sherlock Holmes opened went to answer it.

"Jaawn! Come here please!" Sherlock hollered from the bottom of the stairs.

'Oh God. He said please. He's probably broken something.' John thought, easing himself out of his chair. He got to the bottom of the stairs and found something that he never thought we would see. A tall young girl with short dark brown curly hair and pale skin was clinging to Sherlock, enveloping him in a death hug. "Who the hell's that?" John asked, his brow creased, and the confusion obvious on his face. The girl let go of Sherlock and bounded towards John.

"Hi! Name's Beatrice Holmes! I'm Sherly's little sister. I was gonna go to Mikey's, but Sherly didn't let that happen, he knows how much I hate Mikey." She babbled, occasionally brushing her dark curls out of her face. The girl picked up a black duffel bag, and a dark blue duffel coat. She ran up the stairs and stopped in the middle of the living room. "Wow. Sherly, I didn't know you had such a nice house. The boarding house is nowhere near as nice as this. There are rats in the cupboards." she said matter-of-factly. She sat down heavily on the couch, which John took as a chance to pull Sherlock into the kitchen and shut the door.

"Why is she in our house? Who is she? You never told be you had a little sister? How old is she? Why aren't your parents looking after?" John hissed, keeping his voice low. Sherlock leaned against the table and sigh deeply.

"She's living with us because the boarding school she was attending wasn't safe. You heard her mention the rats. She's turning fourteen this July. My Mother and Father have always hated her. She was even weirder than me and Mycroft, at least that's what they thought. She wasn't cold hearted like the rest of us. She'd always be trying to play with the other kids, and then the next minute she'd be screaming with anger. She hated all of us, except me, because I let her sneak into my room, and I talked to her. She was my only friend. Then they shipped her off to a disgusting boarding school. Do you want to know why? I overheard them saying how derelict it was, and that she'd probably die or something. She's staying." The anger in Sherlock's voice rose, and John decided that it was not a fabulous idea to disagree with him.

"Sir. There's been a development." a man with an American accent said, addressing a man who was sitting in the shadows.

"Yes what?" asked the man, his Irish drawl prominent.

"Sir. Mr Holmes now has a girl living with him and Dr. Watson. Our source says it's his little sister. She's in perfect heath, and is enjoying her time at Baker st."

"Well, we've got to do something about that haven't we?" the man leaned back into his chair, a small smile playing on his lips….

Prize for who ever guesses who the Irish dude is!
