SHERLOCK'S POV

We had quickly made our way to the library, where we had easily found our next clue. Both Abrielle and I had quickly figured out that the murders were connected, and the threatening note at library only confirmed that. The same threatening note that we had seen previously at the bank. The only thing we needed to figure out now is what connected them. Knowing that I would have no luck figuring out this connection in an unfamiliar, very tedious setting I made my way straight back to the flat with Abrielle and John in tow.

"So, the killer goes to the bank, leaves a threatening cipher for Van Coon; Van Coon panics, returns to his apartment, locks himself in. Hours later, he dies." I concluded, summing up what we knew thus far.

"The killer knows that Lukis will be going to the library, so he writes the cipher on the shelf where he knows it'll be seen; Lukis then goes home to his death." Abrielle finished for me, her eyes glinting with curiosity. She was just as confused with this case as I was, no doubt. We were after all equals in both intellect and personality, so there was really no surprise there. This case was just so difficult! Not because of the strange graffiti, or the fact that we can't seem to find many clues. Oh, god no. To be honest I've solved cases with less clues before, no. It was the fact that Abrielle was constantly on my mind. Who was she? What was she hiding? Just the thought of Abrielle made my head whirl. She was a confusing case that I needed to figure out and fast.

"Why did they die, Sherlock?" John questioned, sympathy very clearly painted on his face as he snapped me out of my random thoughts.

"Only the cipher can tell us." I explained, looking intently at the yellow spray painted line captured in the photograph I had taken.

"Thank you for stating the obvious, genius." I heard Abrielle sarcastically say, a smirk lighting up her features.

"I was explaining it to John." I answered back, defending myself from her very rude commentary. There was no need for her sarcasm, I was simply answering John's question!

"Yeah, and quite dramatically too if I do say so myself." She replied, raising her eyebrow as if challenging me to prove her wrong.

"I'll never understand you."

"Oh, I know." She answered back, all hints of a joking tone gone from her voice. I wanted to understand her … I wanted to understand her so badly. She was a girl, a girl that just happened to be my best and only friend's sister. But most of all she was a girl that for some reason I found interest in. She was a strong woman, an independent woman. And a woman that was my equal … a woman that never said no, not even to dangerous situations. She was a risk taker, and adventure seeker, and a woman that for the first time in a long time I couldn't understand. She wasn't obsessed with shoes or clothing like most girls, or obsessed with how she looked or how much money she had. All she cared about was living her life and having some fun. She wasn't cautious or protective, she lived on the edge just like me. She was the definition of genius. She was a multitasker, a talented person that understood practically everything this world has to offer. She was funny and her jokes weren't obvious or dumb. She is understanding. She can figure out what I want when I want it and she can tell what I'm thinking. She is an enigma, and she is the enigma … the only enigma that for some reason I'm actually intrigued by. She was me.

"Who are you Abrielle Watson?" I asked out loud, my eyes scanning Abrielle's eyes for any type of explanation.

"I'm me." She said with a small smile, her eyes shimmering with mystery. I knew it was more than that. She was her, but that's about her past, or the secret she was so intent on keeping hidden? She had a different past, a past that I'm sure she would much rather forget.

"Who are you really?"

"Figure it out, genius." She stated sarcastically, her eyes challenging me to work out the case of Abrielle on my own. This was not going to be easy that was for sure.

"You are impossible."

"Yuppers! Now shall we go find a murderer?" She questioned, getting up from the couch she had previously sat on and walked over to the door.

"We shall Ms. Watson." I stated, walking over to the door and holding it open for her in a mocking manner. She smiled exiting the room, John following not far behind us. For now we would go on with trying to solve the strange graffiti murders. Abrielle was a mystery to be solved, and a mystery that I'm sure will take lots of effort and time on my part. I know that I will most certainly spend hours thinking about her mystery. And eventually, maybe not now or anytime soon, she is a mystery that I will solve. Even it takes me days, or months, or even years of putting the clues together I will figure it out. Abrielle better watch her back, because whether she wants me to find out or not I will figure her out. I will figure out her past, her secret, who she is now, everything. Every little detail. I will solve the enigma that is Abrielle Watson.
