Chemicals And Deduction: Sherlock X Reader

One

Heya guys, so this is my first xreader fanfic and i decided to do a Sherlock one. Before you start reading tho there are a few little things popped around the book that you need to know.
Y/N = Your Name
Y/F/N = Your Full Name
Y/L/N= Your Last Name
F/C = Favourite Colour
E/C = Eye Colour
H/C = Hair Colour
This also takes place in a slightly alternate timeline, basically instead of season 3, where Sherlock and John are working cases, and John and Mary are still just dating 😊
Floss xx

*****
You are rudely awoken by your phone ringing rather loudly. You grunt as you roll over to see the caller ID, cringing at the light. It's Detective Inspector Lestrade. The lazy half of your brain says that you should leave it as it's your day off but the common sense half of you brain tells you to pick it up as Lestrade wouldn't phone you for no reason. As per usual, the common sense half wins. "Yello" you say down the phone, painfully aware of how dead your voice sounds.

"Hey, Y/N," Lestrade says down the phone. "I know it's your day off today but we have an extremely important case that we really need your help on. You couldn't come in could you?" You knew that the last bit was more of a demand than otherwise but you are intrigued anyway, you haven't had a good case in a few weeks.

"I'll be there in the next hour" you sigh.

"Thanks Y/N." You say your goodbyes and hang up. Putting the phone down you stare up at the ceiling. You shake yourself from your bubble of thought and go to the shower and turn on the hot water. As the water runs you feel the tiredness slowly leaving you and circling down the drain. You get dressed and ready, quickly checking yourself in the mirror to try and make yourself look like you didn't get out of bed half an hour ago. Slipping on your favourite shoes, you lock the flat and hail a cab.

You get out the cab and are greeted by a very exited Molly, a specialist registrar at Barts but loves helping on cases. You've always thought that she is always slightly too happy for someone who works in a morgue. "Oh my god Y/N, I didn't realise that you were coming, I thought that this was your day off!" she squeals, pulling you into a tight hug. You love Molly with all your heart but sometimes she can be just the tiniest bit... over the top. You hug back, but then pull away as you really need to get going. God, she's had a rough night again, bless her. She doesn't have the best of luck with romance, bless her heart. 

"I'll talk to you later" You say, backing out of the room. "and you have to tell me about last night so I can beat the shit out of whoever did it." you smile at her reassuringly and she looks shocked and opens her mouth to say something along the lines of 'how did you know that' but she remembers that you're you. She closes her mouth and smiles gratefully before you head out of the room.

You bump into Greg Lestrade on your adventures trying to find him. "Ah, Y/N," He calls "thank God you're here. We need to start this case ASAP. Sherlock and John are just upstairs." he turns to walk away.

"Sherlock!" you exclaim before Lestrade could even take his first step. God you hate that selfish bastard, he only cares about himself or John, not you, not Greg, especially not Molly. Yeah that's right, the famous Sherlock Holmes is a self-centred bitch. You curse at yourself for being quite so blind, but blame it on wishful thinking. Of course he was going to be here!

"Yeah, look Y/N, I know you don't quite get along with Sherlock," Well that's the biggest understatement of the year right there! "but we do need help from both of you. Please just try to not kill him for this case." You sigh in reply. Lestrade takes this positively and turns back around to head up to his office. You follow him up the stairs, double stepping as you do so.

You enter Lestrade's office, greeted by the warm welcome of Sherlock and John talking in hushed voices as well as the disgust on Sherlock face when he sees you enter the room. "Sherlock" you say, not even attempting to hide the hatred in your voice, you turn to John and smile "John". You like John, shame he hangs out with the bitch over there. He returns your smile, also proving your point.

"Well, can we find out about this case then?" Sherlock asks, more demanding than asking, and quite rudely as well. You can't really talk though as you are itching to know what this case is and why it needs quite so much attention.

"Ah, yes, well. For the past four nights there have been a selection of suicides. Now this is quite normal unfortunately, but these suicides are far from it. They have nothing in common with eachother apart from the suicide note which reads- Tick tock goes the clock. I guess my time come. Goodbye, or is it hello? Names and then a name. But one of the many strange things is, the name isn't of the victim, it's of the next one"

"A sort of warning" states John, and Lestrade nods.

"Another strange thing is the part where it says names, with no context whatsoever. That must be some sort of clue, saying that the names of the victims are somewhat important."

"What are the names?" You butt in. He was probably going to say anyway to be honest... Oh well.

"The first victim was called Olivia then they were James, Charlie, Sam and tonight's ones are called Frankie." Lestrade explains.

"Tonight's ones?" Sherlock repeats, obviously picking up the plural that you had also spotted.

"Sorry?"

"Tonight's ones, plural, suggesting that there is more than one person." You explain for Sherlock, gaining a slight dirty look.

"Ah yes, on Monday there was one victim, on Tuesday there were two. This turned to four and then eight, so supposedly, tonight will be sixteen." There is a silence filled with thought. This case is really interesting. You zone out for a second but are brought back down to earth by John calling your name.

"Y/N? Coming?" He asks.

"Oh, um, yeah." You reply. You shoot a quick smile at Lestrade before following John down a couple of flights of stairs to see Sherlock talking to Molly. Oh this should be interesting.
