Chapter 1 – 10 Years Later

Time passed quickly for the Holmes family. Sherlock grew into a curious, emotionally detached soon to be 11-year-old boy. He was classed a high-functioning sociopath at the age of 3 and a genius at the age of 4. He started to deduce things during his 3rd year of living with his new family.

You could usually find Sherlock in either the laboratory, set up when he was aged 8 where he conducted a lot of his experiments. This included a microwave and a fridge, from the time that Cook found a cat's head in one and mould in the other, when called down for an explanation his excuse was:

"I am conducting an experiment on the coagulation of cat saliva after death and another on what happens when the mould Stachybotrys chartarum or black mould is exposed to heat after a growing period of 6 days in optimum conditions."

Or the library, where he usually read books on forensics or others which contained useful facts he would need later on in life. He also spent a lot of time in London so that by the time he was 6 he had memorised the name of every street and could visualise the quickest/longest/etc. route to take to get from point A to B using markers on streets and well known buildings and signs.

He got bored often and was insufferable to anyone he did not like or know and held a strange relationship with his family, especially, with his brother. Him and Mycroft fought like there was no tomorrow, trying to outwit each other with their intelligence.

Yet when tragedy strikes, like when their father died. Sherlock was 7 at the time, and adored the man. He was the one who taught him nearly everything he knew. They become protective of each other. Mycroft more so than Sherlock as he believed it was his responsibility, as the man of the house, as he was now the eldest man alive in the family.

Soon though everything went back to normal with the insults flying, except with one major difference, now when one of his experiments goes wrong, Mycroft is the one who sorts the mess out, or when Sherlock was being bullied during school, it was Mycroft, who got him boxing and defence lessons or came into school when needed, because, he was caught experimenting or deducing the teachers, parents and other class mates, he also got Sherlock a tutor for the violin, when he expressed a wish to learn.

His mother had a strained relationship with him, knowing it was because he was adopted and she forced in to accepting it, she had always treated Mycroft as the better son and was always disappointed about how Sherlock was with emotions. Not understanding what is and is not appropriate to say at certain times, this caused him to be socially inept, saying what is on his mind during social gatherings after deducing their guest's whole life story. Usually reducing them to tears after saying something along the lines of 'he's having an affair with her' or vice versa.

Sherlock was a very independent person from a young age, he was able to do most things for himself from the age of 3, he was told everything about his past, before becoming a Holmes on his 5th birthday, he was shown the letter where he proceeded to make the same deductions his father had, 5 years previously.

Sherlock is cut from his musings when Mycroft entered the lab. Glaring at him as he observed what Mycroft wanted. His brother stared calmly back, smiling slightly at the usual response, walking in to a room with Sherlock present in gained,

Sherlock's POV

"I take it mummy wishes to see me" it was more of a statement than a question he already knew.

"Indeed, brother dear in th…" I cut off as I speak over him

"The drawing room, yes, yes I know. How's the diet, snuck in behind Cook's back yet" when in need of an insult use his weight.

"Very well thank you, and no, leg works your forte, I will leave that up to you. Make an experiment of it"

"Boring, I did that years ago, it was spectacularly easy, I managed to escape with most of the sweet stash you had hidden" I smile up at him as Mycroft realises exactly which stash I am talking about.

I become bored with just listening to him, so I try to ignore him, returning to my experiment, to find that too much heat has been added to the plastic causing it to melt way past what I needed. Blast. I pick it up and chuck it in the bin next to my work space.

"So that's where it went, I was so wondering. You turn 11 tomorrow; the wizarding world will not leave you alone; the letter attested to that. What are you going to do?"

"Not, that it's any of your business. But I'm going to play along and observe, whilst acting myself. How I wish I had my violin right now, you ruined my experiment."

"Such a shame. Well then I wish you luck on your endeavour and may I say, I very nearly pity those who abandoned you. I'll ensure you have a working phone, far be it me who unleashes a Sherlock with no forms of communication, in to the midst of those at Hogwarts. Don't forget mummy."

"Do try not to start any wars this afternoon you know what it does to traffic"

"Very funny"

I wait until I know Mycroft has gone before I restart the experiment I was conducting. Mummy can wait.

Clara Holmes POV

Ms Clara Holmes, mother to Mycroft and Sherlock, was sat in one of the high-backed chairs, thinking on her late husband, the sudden and unexpected death of her husband, Sherrinford Holmes had hit her hard; the once joyful, happy woman had become a cold and emotionless husk when around others, with the exception of her sons and the help.

She wore the finest clothes money could buy, had on perfect make-up and her long golden hair was woven in to one of the most elaborate hairstyles with curls and grips. In short she was the perfect example of a high socialite, which of course, she was, being one of the richest in the world; she had 2 geniuses as sons, in whom one was basically the British government, MI5, Secret Service or any other department he needs at the time, yet when asked, will say he holds a minor position in the British Government.

A knock on the door announced the arrival of Sherlock. As he entered the room she watched as he observed her, smiling when he finally spoke.

"Your upset mummy"

"Yes Sherlock, I've been thinking about your father"

She watched the barest flicker of pain cross his face at the mention of his father disappearing so fast she could believe that most would say she imagined it; she however was not most people. How she worried about her adoptive son. Unable to understand emotions and deal with situations that involved them, she knows he chooses to ignore them completely, as seen in his next statement.

"Mycroft said you wished to see me."

"Yes your birthday is tomorrow. Friends and family will be visiting. You will behave. I do not want a repeat of what happened last time. There will be no experiments involving recently dead animals and knives. I still don't know how you got hold of them. Also there will also be no deducing who's sleeping with whom, causing yet more breakdowns. And you will most defiantly not show up covered in blood again; people thought you had killed someone."

"It was cow's blood; it's not my fault people cannot differentiate between the two."

"That's not the point, Sherlock; the point is that you almost gave several people heart attacks with your sudden appearance whilst covered in blood. Ambulances needed to be called, because more than half were in shock and at least 2 were sent to hospital."

"Very well mummy I will try to refrain from conducting any experiments, involving things like blood."

Relief washes over her, after that statement, she will be fine, he has said he will try that was something, on the other hand, he was Sherlock so she will continue to be cautious, I must remember to get someone to run through his lab before the guests arrive, just to double check.

"Thank you, now like your brother before you did, you will be going to a boarding school at the start of this academic year. Do you know where you wish to go?"

"Yes, Hogwarts, mummy, I believe I will have very little choice in the matter, I doubt they would leave me alone unless I do"

"Yes, you're correct, I saw the letter. Very well, you may go."

"Yes mummy, shall I send James in?"

"Please if you wouldn't mind, thank you."
