Moriarty x Sherlock sister!reader
Prompt : You’re with Jim Moriarty, the world’s only consulting criminal and you have to tell it to your brother : the world’s only consulting detective…
You’re Y/N Holmes and you’re family is quite special. You have two brilliant brothers but you’re very clever too. You have a social problem but you can manage to get through it and have a quite normal life.
It has been a month, you are in a relashionship with the world’s only consulting criminal and tragically your brother is his arch nemesis.. And he doesn’t know about you and Jim yet..
Today is the day, you have to tell him, you have to tell Sherlock, you know it. The sun is shining outside, you’re in the bed you share with Jim, you had a good night and everything is ok. You get out of your bed, the smell of the pancakes leads you to the kitchen where you found a paper with “from Jim with love. Don’t wait for me tonight, darling.” written on it. Pancakes always hide something but there are delicious.
Then you dress up, take your courage and order a taxi to go to 221B Baker street.
Here we go. You open the door and see Sherlock playing violin and two cup of tea ready to be drink on the table. “Wait, what ? Did you just make tea ? “ you just can imagine your brother doing something as normal as tea.
“oh Y/N, I wasn’t expecting to see you
-yeah, I see, you’re waiting for someone ?
- Y/N, you know that someone break into the tower of London recently and that this person is the one who tried to blow me up in the swimming pool
-Did someone actually break into the tower of London ?”
“Oh my god, this wasn’t suppose to be like that. Sherlock is waiting for Jim and you’re here. Morever, what’s the story with the tower of London ? How can I not know that ?” you thought
“So Y/N, it’s not that I don’t like you but you’re not supposed to be there, this isn’t part of the plan”
“You got a plan ?” You hear the too-much familiar voice from your back
“Must people knock but you’re not must people I suppose”
You’re in trouble, Jim is going to see you, and to say something that will make Sherlockfurious, that is going to happen for sure, what can you do to stop an atomic war between your brother and your boyfriend ?
‘Wait a minute, I have something to say to Sherlock, Jim don’t talk “as you see him opening his mouth to say, you know it, something about your relationship.
Sherlock raises an eyebrow, how can you talk to Moriarty like that ?
“Sherlock, what I am going to say isn’t a joke, don’t be mad and I’m sorry for everything that will happen next but I am with Jim Moriarty”
“You’re with him ?” Sherlock says like he doesn’t understand
“yeah, two people living together and loving each others, just like you and john” Moriarty says
Oh no, he did it, he just implies that Sherlock loves John, could not be worse…
“Ok then, you don’t need me obviously so uhm.. bye” and you get away as fast as you can from you brother which is getting a little angry (not to say furious).
Two week had passed since that day and your brother don’t want to talk to you anymore. Of course, your other brother, Mycroft, came to “talk” to you. Well, you clearly have been told to leave Jim. And you declined the offer with yellings on your brother. So now, you just have Jim who is, you can say that, really happy to be with you just because of Sherlock’s reaction.
“You should have seen his face” Jim tell you it every day when he thinks of Sherlock.
“Ah ah ah. Thank you Jim for your compassion. Do I have to remember you that it wasn’t suppose to happen like that. You should have tell me that you were going to see Sherlock and by the way that you stole the crown jewels !”
“Oh Y/N, darling, you know that I really like when you get angry, that makes you really sexy”
And you always lose at this game because you just love Jim too much.
You wake up late, it’s about 11 a.m and you can’t find Jim in your flat. He didn’t let you a note like he usually does and moreover there’s no pancake. So you try to call him but his phone is on the table.
This isn’t ok. Something is going to happen to Jim. You have to find Sherlock. Only him can help you because he is the only one consulting criminal.
Baker Street. There is no one in the flat. No Sherlock. No John. You decide to see if Mrs Hudson knows something. She told you that Sherlock and John have been arrested, that they escaped and that they are runnig in London;
There is a link, both Sherlock and Jim disappeared suddenly the same night. You have to find them before the fall. Jim always says that the world will end in a fall. That’s what is happening.
If Sherlock has to find something he must be in St Bart’ hospital. So you get a cab and go there.
You enters in the lab but it’s empty, not even the girl Nolly, Molly well something like that.
And you heard a gunshot from the rooftop. Oh no that is not good. Not good at all. You get the stairs and you find on the roof a dead body lying on the ground, Sherlock is on the roof edge calling someone.
What the hell ? Who’s dead ?
You’re getting closer to the body and you can finally see his face.
“Oh no. Oh my god” You run to Jim to see if you can do something to save him. “No he can’t be dead” “It can’t be” “No no no no no” You can do nothing than holding his body and crying of despair.
Sherlock screams to you that he is sorry about what happend and about what he is going to do. He says that he can’t stop it. But you are focused on Jim’s face. And you see Sherlock jump from the roof.
You don’t understand. You hear foodsteps from the stairs but you can’t move, you just stare at Jim’s dead body.
Someone beats you in the head and everything gets dark.
Thank you for reading. If you want to say something, it’s open, I will maybe do a part two. Sorry for the mistakes.
