Elizabeth Pov-

I watched as John stood in shock at my presence, I took a glance at his flatmate Sherlock who had allowed himself into my flat and began snooping.

"Elizabeth what on earth are you doing here?"

"You know the usual being bored and that"

John embraced me into a hug before pulling away and pointing over to Sherlock who was now slouching in my chair.

"That's Sherlock my flatmate. He's about to do something very annoying and obnoxious and he isn't completely aware he's going to do it so I apologize ahead"

"Your name is Elizabeth Holmes you're aged 24, three years younger then John and two years younger then Harriet. You've recently moved out from your parents hence the mixed type of packing, some of it is neat and the other lot is messy which also indicated that you were in a rush, probably to get away from the stress of your parents. You're a writer hence why you don't wear nail varnish because it chips when you type or write on paper- very logical. John's surprised to see you which means you both don't keep in touch as often as you like however he has trained you in the arts of war, gun shooting which explains why you have a gun on top of the fireplace and a knife in your pocket. Your ambitions are to be a writer however your also a teacher, only part time I'm guessing Monday's to Wednesday's judging by your folder work on your laptop. Yes I went through your laptop, problem?"

Sherlock jumped out of my chair and walked over to John.

"She's boring, can we go now?"

"Sherlock that's my sister!"

"Your name is Sherlock Holmes and you live at 221B Bakers Street with my brother John. You go out solving cases with him although it's normally just you with your deductions- John's just there for second opinions. People are easily irritated by you hence why you have no hairs other then yours and my brothers on your jacket meaning people like to keep their distance from you. Someone you work with has a crush on you, a female probably someone who works quite close to bodies, you can tell this by the faint lipstick marks that have found their way to the collar of your jacket, whoever she was must have been quite close she was probably trying to attract your attention. You have a relative who's OCD probably a brother, you can tell he's OCD because when I entered the building the door knocker was bent, I straightened it and I bet I was to go out there now it'd be bent. You're easily bored and you play the violin, the last time you played it was three hours ago hence the faint violin string patterns on your fingertips. By the look on your face and my brothers you're both shocked I'm saying this, is that so?"

I smirked at both their faces which held shock.

"John you're forming questions in your head, spit them out"

"Where the hell did you learn to do that?" He asked.

"I didn't learn John I noticed"

"You sound like him" John commented, sticking his thumb in the direction of Sherlock who was still silent and was staring.

"That's off putting Mr Holmes" I informed him.

He shook his head letting his curls bounce before turning to face me.

"Extraordinary! Someone on this planet that's not stupid-"

"Thanks Sherlock, ignore your flatmate and compliment his sister instead"

"Shut up John. Mondays to Wednesdays am I right?" Sherlock asked.

"Correct"

"Tomorrow 8am sharp, we've got a case"

With that Sherlock turned off and walked up stairs to his flat leaving me and John stood at my door.

Sherlock Pov-

My mind raced at the thoughts of Elizabeth. She was clever, probably as clever as me if she'd put her talents to use. John's sister, who would have guessed except me? I thought of her standing in front of me, slim body with curves, height so the top of her head reached my nose, brunette hair which formed curls at the end which reached midway to her back and green eyes, forest green eyes.

"Sherlock you're thinking about my sister aren't you?" John asked as he entered the flat distracting me from my thoughts.

"No. What makes you think that?"

"You've got your thinking face on?"

"I have a thinking face? Since when did I have a thinking face? That's a dead giveaway, my thinking face is going to have to go"

"Shut up Sherlock. Now make me a promise-"

"What kind of promise?"

"I know that you intend to drag Elizabeth along with our cases so if you do, promise me you'll keep her safe"

I looked up in John's eyes and saw concern and worry for his sister. I simply nodded my head before drinking some tea.

"I promise"
