John glanced up as Sherlock walked in to the room in and was about to say hello when he noticed the bundle in his arms, his curiosity spiked and then he worried.

"Hi Sher- What have you got there?" John's voice had an accusing edge to it "What have you done now?

Sherlock ignored John's dull questions and started to walk to the kitchen avoiding eye contact, he had hoped would be less observant than usual but he wasn't sure that was even possible. John raised his voice know that his friend had heard him.

"Sherlock?!"

Sherlock turned around doing his fake smile as he tried to decide what to say to John.

"John I need your" Sherlock paused looking for the right word "Expertise."

John looked suspiciously at Sherlock trying to work out what he wanted, he glanced at the bundle in Sherlock's arms again.

"If you want me to take part in one of your highly dangerous, pointless, not to mention irresponsible experiments think again. You'll have to find another lab rat."

Sherlock pulled his annoyed face "Science is not irresponsible and none of my experiments are pointless, my experiments are however at this moment irrelevant. Now as I was trying to tell you earlier I need your expertise, John what do you know about infants?"

John spat his tea back in to his mug and looked again at the bundle in Sherlock's arms.

"Where did- Who have you taken it off? Sherlock people don't just come home with babies!" John managed to splutter out.

Sherlock looked at John with what some might describe as distain, he had hypothesised that John would over react less because he had been living with him for a few years and had got used to his habits, Sherlock concluded that he had been wrong.

"I am not people. I took it from a crime scene," Sherlock raised a hand to stop John speaking "it's mother and father are dead, yes it was murder, Lestrade didn't know about it while I was there the homeless network told me, I had the crime scene to myself, there was no evidence, the killer was meticulous and there was nothing apart from the two bodies with the small stab wound in their chest, the baby is the only witness and we are keeping it until it can make a statement and hopefully lead us to the killer. Has that answered all your questions?"

John nodded, keeping a straight face for as long as possible until he cracked and started laughing. Sherlock looked puzzled and then gave John a scathing look when he realised he was laughing at him.

"Yes John it's very funny, hilarious, I glad the key to solving the crime has amused you so much. We only have to keep it until it can talk, which I hoping will be in a few days' time and then it can give a statement so I can work out the rest and tell the police what happened."

John tried to keep his face serious but there was still mirth in his voice.

"What are we going tell Lestrade?"

Sherlock looked at him and they both started giggling, when they recovered John reached for the baby so that he could have a look at it. He studied its face, it had curled black hair and blue-green eyes and it looked remarkably like Sherlock. He check to see if it was a boy or a girl and groaned when he saw it was a girl, he had no idea how to raise a baby girl, because of course it wasn't going to learn to talk in a few days like Sherlock expected. And she needed a name. John saw Sherlock looking at him and realised he had been thinking out loud.

"Wonderful observations John, it is as you said similar looking to be but it is not as you suspect mine, yes it is a girl but I thought all children were raised the same anyway. I propose we call it Hamish as you were so willing to suggest it as a baby name when Ms Adler was visiting and we tell Lestrade it is my niece." Sherlock said, it was clear to John he had already decided on this and was just telling him rather than asking, he had known Sherlock long enough to know that.

"You can't call it Hamish it's a girl although I assume people will just thing it's another one of your family's weird names." John added the last bit teasingly.

Sherlock's phone started to ring.

"Lestrade…double homicide, I heard…hair like mine at the scene? It is mine…yes I've already been there…I was passing by…I don't care about Anderson, you really should fire him he's an idiot…There's no point and I have to look after my niece…I wasn't dumped on me…John's helping…Hamish…no goodbye Lestrade."

Sherlock looked at John "Lestrade's coming you need to dress Hamish."

John shook his head "Oh no, you brought her here she is your responsibly."

John held the baby out to Sherlock and chuckling at the face he made.

"Fine! I don't need your help anyway."

Sherlock practically snatched the baby from John, jostling it awake. John was surprised that Sherlock had snapped and then realised that he had meant what he said, Sherlock really did need Johns help, he was just reaching out for it when Lestrade arrived followed by Mycroft. John knew he shouldn't be surprised that Mycroft was there, he knew he bugged their phones and had them under constant surveillance. Lestrade spoke first.

"I didn't think you two would be telling the truth about having a baby but still congratulations you two." There was a mocking smile on his lips.

Sherlock ignored him.

"Brother dear, I should have known you would be listening to my phone calls. Spying on me, I would like to say I expected better but I didn't."

"And I would have liked to have known I had a niece sooner, still I would like to know the name of the woman who captured your heart," Mycroft smiled wryly

"And how you managed to evade my surveillance."

Sherlock paused for a moment. "It's not mine Mycroft you really are getting slow, it doesn't even look like me."

Mycroft looked at his watch "Well I must leave I'm afraid the Luxembourg- never mind. Remember to tell be next time you have a child appear."

Without further talk he left. Lestrade stared at the baby Sherlock was holding at arm's length.

"You really chose to look after the baby?" Lestrade shook his head.

"Yes now if you're just going to question me then leave." Sherlock turned his back on him.

"What about the case? Any theories?"

"No. Leave."
