By the time two weeks had gone by Sherlock was starting to wonder what was taking his brother so long to sort in Latvia. It was not like he minded looking after Emily, no he adored the girl it was just that he had told Lestrade that he was not available to take any cases unless they were a nine or ten. While there had been plenty of eights in the last two weeks there had been no nines or tens and Sherlock was getting bored.

Sherlock knew for some weird reason John was quite keen for Emily to meet Lestrade and it wasn't that Sherlock minded taking Emily to a crime scene and well Emily wanted to go to one too. He just wanted to keep her away from Anderson and Donovan who would most likely call the girl a 'freak' and while he could stand himself being called that, he would not put up with Emily being called that.

So it was with some trepidation that when he got a case after Emily had been staying for 17 days, did he approach them at breakfast.

'John, I just received a text from Lestrade apparently they have a case which is a nine and they need my help on it.'

'Okay, you go and I will stay home with Emily.' John replied looking slightly disappointed, after all it had been 17 days since he had an adrenaline rush.

'I want to go. It's not fair, how come Uncle Sherlock is allowed to go out and have fun and I'm not,' piped in Emily who at the mention of the word case had been looking incredibly interested. 'It's not like I haven't seen dead body parts before, only yesterday we were using a human head in an experiment and last week we were putting fingers in acid to see how long it took for the flesh to dissolve.'

John turned to stare at Sherlock, 'You let your six year old niece play with dead body parts Sherlock. What is wrong with you she is six?'

'Yes, she is six, good observation John, but she is by no means stupid or not ready to be doing this. May I point out that the girl is a Holmes; she is already capable of speaking 3 different languages, knows 10 different ways to kill you with a biro and can tell you which side you prefer to sleep on and that you used my shampoo this morning. She has been wanting to copy me and do experiments since she was two, and don't even think of saying what would Mycroft think because he is well aware of what his daughter gets up to and while he doesn't always like it, he has learned to accept it because it is what she wants to do. Now you said you wanted to watch Lestrade meet Emily and since Emily and I are about to do so, if you want to join us you are most welcome to.'

John sighed and went to grab his coat whilst he wasn't happy with the idea of a six year old going to a crime scene he could tell that there was little he could do to stop it and even if he did try she would probably go and jump in a cab and make her way there by herself. When he returned he saw his boyfriend and niece wearing almost the exact same coats and expression on their faces.

'Her coat is almost identical to yours, right down to the red stitching around the button hole' he commented

'Yes, Mycroft had her one made after she told him she wanted one, he wanted to get her a miniature umbrella but she would rather have had a coat.' Sherlock replied

'Well it wasn't that I didn't want the umbrella but he wasn't going to put the sword, laser and gun that dad has in his, and well then all it is good for is keeping off the rain.' Emily stated

John opened his mouth in shock, he had often wondered if Mycroft might have a sword hidden in the umbrella but he never thought that he might have put a gun and laser in it as well after all who would need all three. Well it seems that the British Government might.

It turned out that Emily was just as competent as her uncle at hailing taxis, making John feel slightly ashamed as he sat in the back that a young girl was better at this than he was. He had learned to accept that this latest guest of 221b was smarter than he was in many ways but the idea that she could do something that he had just put down to Sherlock's height annoyed him.

'So do we have any details about this case' John asked Sherlock.

'Well apparently they have found a body which is only 24 hours old but the flesh has all dissolved.'

'How do they know it is only 24 hours old?'

'According to Lestrade the person was found in a bath tub and they have not been moved since they were killed because none of their bones have been broken to put them in that position so either they were killed there or put there in the first few hours of dying and the owner of the hotel in which they found say that the room was last cleaned 24 hours ago so the person was placed there in that time and they could have only been a few hours old at said point as the body was still able to be positioned.'

'Cool' Emily piped up.

When they arrived at the scene, Donovan was standing there looking fed-up. When she spotted Emily she looked startled. 'Freak please don't tell me you have kidnapped a child'

Sherlock rolled his eyes, 'of course not Donovan, this is my niece Emily. Emily this is Sgt Donovan, stay away from her I don't want her inability to accept people who are smarter than her to make you feel bad.'

Sherlock picked up the police tape and herded John and Emily inside before following himself. 'Shut your mouth Donovan or you will catch a fly,' Sherlock called back to her.

When they reached the body, Emily and Sherlock both pulled out mini magnifying glasses and started looking around. It was a couple of minutes before Lestrade turned up, with another police officer who seemed unfamiliar to Sherlock.

'Sherlock have you got…' Lestrade started before noticing Emily standing there. 'Sherlock who is this child?' He ended up asking instead.

'Oh this is my niece, Emily. Emily say hello to DI Lestrade.' Sherlock replied

'Hello detective inspector' Emily said quickly before turning back to look at the body.

'I didn't know you had another sibling other than Mycroft'

'Why would you say that?' Sherlock asked

'Well she isn't Mycroft's daughter 'Lestrade stated

'Mycroft is my only sibling and I've seen her DNA test myself this is most certainly Mycroft's daughter' Sherlock replied confused at why the DI didn't get this fact.

At this statement the DI collapsed onto the floor hitting his head on the toilet bowl in the process.

Sherlock turned to John, 'Why did he just do that?'

'I guess that's what happens when you find out that your fiancé has a daughter that you didn't know about'

'You mean, him and… urgh that disgusting… and they are…. My head' with that Sherlock collapsed as well and managed to hit his head on the sink.

Emily turned around to face the police officer 'You will find that there will be traces of quick lime on this body that was how they were killed the person was knocked unconscious in the bath and covered in quick lime.' She then turned to John, 'It seems that these two will be need of an ambulance, oh and you may want to tell my father that his fiancé and brother are both unconscious with a head injury. Oh and tell him I say congratulations but next time he decides to make big life decisions I would like to hear about them from him.'
