If Mycroft was to write a letter to his younger self what would he want to tell that boy that he once was? Give him some advice? Or maybe even warn him?
You remain unaware toward the turmoil of the path that may or may not be set into motion after receiving this letter.
I struggled for many weeks on what I should put into this rather than if I should send it at all however, it is with high aspirations for a more positive alternative, even if it erases all I’ve come to achieve in over 40 years of my life I feel that I must inform you of what is to come.
Be advised what I am about to elaborate on will be difficult to swallow given it deals with our sister but nevertheless for the sake of their health and sanity please struggle to read on.
It is on a summer’s afternoon prior to Eurus’ sixth birthday that you may find yourself out by the lake with Sherlock, Eurus and a young boy named Victor. He will be Sherlock’s first and only companion outside of our family at the tender age of seven and it is imperative that you keep Victor away from Eurus at all costs for if you fail to do so he will killed by her.
Apparently Eurus was jealous and lonely due to Victor’s friendship with young Sherlock and set to right it by throwing the boy down a well and leaving a riddle for both his family and Sherlock to locate the body. She also burned down our home, Musgrave.
Unfortunately, we were unable to find the body’s location until several years later and it changed Sherlock as it did Eurus as well. Sherlock bottled up his emotions and ‘deleted’ (you’ll come to understand what that references in 10 years with technology progressing) the memory of both Victor and Eurus. He became colder because of it.
He will no longer be our silly and loving brother and seek to fill the void with drugs until he overdoses. Fear not, we managed to save him and break Sherlock from the habit cold turkey but I remain resolute that this should be avoided and watched should you fail to keep Victor safe from Eurus’ wrath.
Eurus too will be changed. She will become more bold with her actions as even thought I sent her to a holding facility/psychiatric sherriford ward for her benefit Eurus managed to manipulate the other inmates and stage a coup. She comes and leaves as she pleases causing mayhem and pain for Sherlock and anyone unfortunate enough to be caught in the crossfire.
Eurus is difficult to maintain or stop. It is imperative that we stop her now before she begins to start her reign of terror.
If anything I would talk to Mummy and Father about her. Yes, I understand that they have their reservations about her because her intellect is deemed ‘incandescent’ while we stand at ‘remarkable’ on the genius scale but do what we do best: collect all the evidence and provide it in the most concise manner that you can.
Do it as many times that you can and be sure to thwart any attempts Eurus might have toward Victor in the future. Try to play with her more or at the very least schedule time for Sherlock and Eurus with you minding them both.
We both know how manipulative she can be and that Sherlock is hardly the most clever out of the three of us. You must remain vigilant to her advances and never waver.
I acknowledge that sounds like a very grim and tedious sentence for one so young but I assure you that in doing so you are keeping the happiness of both siblings in check along with countless lives lost in this little ‘game’ Eurus wishes to play out with Sherlock.
You are doing this for the greater good and even if it is not recognized by anyone you can find some comfort that your older self is proud of your efforts.
I fully understand how ridiculous this sounds that our baby sister could be capable of such a thing but let’s be honest there are signs. You and I both know we’re smart enough to recognize it and not second guess ourselves.
We may not be the smartest Holmes but we aren’t the dullest goldfish in the bowl.
Use your resources fully to their extent , keep your eyes open and do your best.
I have faith in you and in time, Sherlock will as well.
Kindest regards and well wishes,
Mycroft Holmes, 8-August-2017
P.S. It would be wise to invest in a company called ‘Apple’ which will birthed on 1-April-1976 in Cupertino, CA. On the back of this letter are detailed instructions on how and whom to invest that money from our previous birthdays. Having ownership in it will greatly help us keep an eye on both Sherlock and Eurus in the future.
P.S.S. Should you succeed in keeping Eurus from murdering Victor please look up Captain John H. Watson MD. He will become an invaluable associate to our cause and another dear friend of Sherlock and (by extension) ours as well.
There is also a young woman named Molly Hooper who will also can become a big part of Sherlock’s life so be sure to fabricate a way if you can for them to meet.
