Sherlock was sitting in his chair, in 221b, when he received a text from his brother.

I need you to do me a favour, it seems that Emily is taking after you; she has just informed her class that her teacher is having an affair with another teacher and is pregnant. Meaning she has been expelled, I am currently in Latvia can you please look after her till I return. MH

Sherlock smirked, his 6 year old niece was showing that she was clearly a Holmes and even better still taking after her Uncle and not her Father, this was going to be driving Mycroft mad. Although he was slightly worried what he would do with a 6 year old, especially seeing as very few people knew about her. He hadn't even told John about her even though they had been dating for 6 months.

'Urrrrhhh John we are going to have a visitor come and stay with us for a while, I just need to go and collect her' he called out as he put on his coat and shut the door. As he was rushing down the stairs he heard John calling from behind him 'Who is it and why are they staying with us?'

When the cab pulled up at the girl's boarding school he asked the cabbie to wait whilst he went in fetch the girl.

'I'm here to fetch Emily Holmes; I am her Uncle, Sherlock.' He informed the receptionist. She looked up and him and her eyes widened, ' Are you Sherlock Holmes the consulting detective?' She asked with excitement clearly in her voice. He rolled his eyes and nodded his head, after all surely it was obvious, he had said his name was Sherlock, said that his niece had the surname Holmes and he was picking up a girl who was clearly very bright and was making impressive deductions so surely it was obvious and did not require a question.

'Are you free tonight, you know to go out for like a drink with me. You see I am a big fan and I love your blog.' Sherlock couldn't understand why girls still acted like that towards him, after all for the last 6 months since he had returned he had been dating John and well he was sure that John had mentioned it at least once in his blog, but still he had people asking him out for a date even though he was taken, he could not understand why humans did such things. 'I'm afraid I am already in a relationship with my blogger, would you mind hurrying up and getting my niece as I have a taxi waiting.' He replied carefully, having been taught by John that being nice to people, even if said person was an idiot, would help him to get what he wanted quicker. The lady blushed and scurried away and returned with Emily and a large bag 5 minutes later.

'Uncle Sherlock' the 6 year old cried out and jumped into his arms. He grabbed the bag flung it over his shoulder, gave a nod to the receptionist and walked out the door. 'So Emily, I hear you have been deducing your teacher.' The girl looked up at him with a smug look on her face and nodded. 'She has been cheating on her husband with the year 5 teacher, she came into school every Thursday smelling like him, and now she is getting larger and she keeps eating peaches which she once said ages ago she hated so she must be pregnant, although I am unsure who the father is, whether it is her husband or the teacher.' Sherlock burst out laughing and looked proudly down at his niece who was resting on his hip. 'Let me guess, she didn't like this when you pointed it out, even though it was obvious.' Emily nodded. 'No, they never do. It's alright I don't understand it either.' She smiled up at him. They reached the taxi and with a bit of logic and a lot of shoving they got the case in the back. '221b Baker street please' he told the Taxi driver. Sherlock turned to Emily, 'Now you are going to meet John, I didn't get the chance to tell him about you so go gently with him. No, he doesn't mind deductions but he doesn't like experiments so I'm afraid we will have to keep those at a minimum this time. Oh, and if you hadn't worked out already he's my boyfriend and I love him so if you want to I guess you can call him Uncle John.'

The cab soon pulled up to 221b and they hopped out, Sherlock climbed up the stairs carrying the bag with Emily following slowly behind him. 'John, I'm home' Sherlock called when he reached the top of the stairs. 'I'm in the kitchen' John replied. Sherlock left the bag at the bottom of the second stair case as Emily would be staying in John's old room. He grabbed Emily's hand and walked into the kitchen.

'Sherlock when you said we would have someone staying with us, I presumed you meant someone who is an adult. Please tell me you did not kidnap that child.' John said as he started at Emilly. Emily burst out laughing and Sherlock looked at John in horror because how could he ever consider him doing that. Well maybe when he first knew him but not now, not after John had taught him so much about human emotions. 'No John, this is Emily, my niece, Mycroft's daughter, Mycroft has asked us to look after her till he gets back, she got expelled today for well I guess being a Holmes.'

'Mycroft has a daughter?'

'Well yes that's what I said, although he doesn't exactly advertise the fact, he doesn't mind people knowing, he is just worried about her safety.'

'Wait a minute I thought he was...'

'Yes my father is Gay; I was an accident when he was really drunk he took me from my mother who was hopeless 9 months later when I was born. No I do not miss the woman; she turned out to have a drinking problem and was violent when drunk. Almost killing me when I was a month old that's when Daddy took me away for good.' Emily piped up from beside Sherlock.

'So let me get this straight, Mycroft has a daughter who I'm guessing was deducing all the teachers so got kicked out of school.' John said trying to remain calm and level headed, although ending up feeling utterly bewildered and confused.

'Pretty much' Sherlock replied. 'Come on Emily let me show you to your room upstairs.'

5 minutes later Sherlock returned downstairs having left Emily in her room to unpack. 'Does Greg know about Emily?' John asked him went he got into the kitchen.

'Greg?'

'Lestrade,' John said as he rolled his eyes.

'Oh, no of course not why?' Sherlock replied.

'No reason, just if you introduce them I want to be there.'

Sherlock nodded and shrugged it off.
