Eccedentasiast (A BBC Sherlock Fanfiction)

Seven ; Sherlock

I shoved open the doors to Mycroft's office. "What is it ?" I demanded, ignoring the fact that he was on the phone. He muttered a hurried apology before slamming the phone onto the receiver causing the only photo on his desk to jump. It was summer and Liv had somehow managed to get Mycroft to pose for a picture. I recalled the smirk on my face as I took the photo. Mycroft stood awkwardly centre frame, freezing as Liv wrapped her arms around him. We all missed her, we all coped with her death differently. "I have news." I was brought back to earth by the sound of my brother's voice. He glowered at me, turning the framed photo to face him. "That much is obvious but what is it ?" He pinched his nose before speaking. "We found her killer." I inhaled sharply, mind spinning. After all this time. John was as dumbfounded as I was but the shock was turning to barely concealed nervousness. I'd gone mad after her death, who knew what I would do to the killer. I clenched my fists, bracing myself for the name. He pulled a file out of his desk before tossing it to me. "Adrienne Mauvais." He stated, placing his hands on the table. "Who ?" Asked John, voicing my thoughts as he peered over my shoulder. I frowned. There were no pictures and there was very little information. I shut the file and looked to Mycroft. "We know very little about her and what we do have is the product of years of digging. She was an assassin, a good one at that. She was hired to-" he choked on the words, looking sick. "To kill Liv." I growled, my nails digging into my palms. "How can we find her." I was filled with hate for this woman. She'd taken a girl who I considered a sister. She was going to pay. Mycroft winced. "That may be tricky considering she died three years ago." I looked down at my shoes, clenching my jaw as Mycroft finished. "At least we tried brother. If we hadn't we would never have known."
"What ? That the person who ripped someone we all loved from our lives just died ?! No justice, she didn't pay." John started to protest but I swept out of the room. I hailed a cab, ignoring my shaking hands and the tears that threatened to fall.

I strolled into the coffee shop, scanning the room until I saw her. Lucille had sent me a very cryptic text telling me to meet her here. I was still reeling from the previous news but I'd arrived in any case. She sat in a booth, nursing a bottle of beer as she chewed at her nails. I slid into the seat opposite her. "Why am I here Fitzgerald ?" I asked brusquely, moving her drink out of reach. "Hey !" She lunged for it, scowling as I lifted it in the air. "I can assure you, that is not a good idea, where did you even get the beer from ?" She evaded the question, slouching in her seat. "I have a clue as to who the next victim will be." I rested my chin on my hands, motioning for her to continue. "Both of the previous victims came here before work every day." Her eyes glinted and I watched with interest. She enjoyed this as much as I did. Peculiar. "I asked the cafe for a list of their regulars, we can review them at 221B."
"Why did I have to come here then ?" She gave no reply, standing up to leave. I followed her outside. After a few futile minutes we came to the conclusion that we wouldn't be getting a cab. "Walk ?" I nodded, striding forwards and smirking as she ran forward to keep up. But that was when it started to rain. At first it was a steady drizzle and we walked side by side in silence, but then it got stronger and stronger until it was pouring, borderline torrential. We were forced to take shelter in the nearest building, a library. We must've made an odd pair, drenched in rain as we staggered into the building. We took a seat by the window so that we could leave as soon as the rain died down. It was only three o'clock but the sky was dark and stormy and the library was filled with the sound of rain hitting the roof. Lucy sniffed as she selected a book and sat down. "By my estimations, tomorrow you may come down with a cold." She smiled slightly before settling down to read. I peeled off my waterlogged coat, draping it over the desk before taking a book, sitting down in an armchair and starting to read.

We'd been sitting in silence for the past hour and a half, engrossed in our books. Suddenly, a thought came to my mind and  I slammed my book shut, earning me a glare from the librarian. A woman in her late 50s whose face seemed to be in a perpetual state of irritability. I flashed her an apologetic smile before turning to Sherlock who was staring at me inquisitively. "You know what, you know so much about me whereas I know nothing about you." He frowned before closing his book and folding his hands underneath his chin. "So ?"
"So it's not fair !"
"Life's not fair." I glared at him. At first he ignored me, starting to read again, but after a few minutes of my eyes boring into  his book, he sighed and put down his book. "So what do you propose ?" He asked, leaning back in his chair. I paused. "Twenty questions." He frowned in puzzlement. "I will ask you twenty questions and you, in turn have to answer them completely honestly." The detective sighed, considering the deal. Just as I was about to ask him again, he spoke. "I accept. Twenty questions, all of which I will answer with the absolute truth." I smiled before pondering over what to ask him first. "Who's Mycroft ?" I recalled the name I'd heard John say before he went to answer the phone. "My brother." He replied emotionlessly, his tone telling me all I needed to know about the state of their relationship. "Ok, question two : Do you have any other siblings ?" He hesitated before answering. "One. Eurus, although she was locked up in a government sanctioned psychiatric facility from a young age so she wasn't much of a sister. But Liv was like a sister to me I guess." His eyes widened as he realised what he'd said. I pounced in his vulnerability. "Question 3 : Who is Liv ?" He buried his face in his hands before speaking. "Olivia Greene née Holmes, my cousin. She was born when I was nine. Our families were, and still are, incredibly close so naturally we were very good friends. Everyone knew her, John, Mrs Hudson, even Lestrade but then two years ago, she was murdered, shot through the heart by woman named Adrienne Mauvais." His voice cracked on the last syllable and I looked away, heart racing. Olivia Greene née Holmes, Liv I hadn't thought much of it at the time, the same name, same style of dressing as my last job as Adrienne Mauvais, assassin extraordinaire. I hadn't managed to get a good look at the girl through my gun scope but I could just make out her blonde hair that cascaded down her back in ringlets. The rain had stopped. I turned to Sherlock, forcing a smile onto my face. "The rain's stopped, we should go." He stared at me in confusion. "But what about the questions ?" I managed a mischievous grin, a façade to hide my fear. I stood up before turning back to him. "You never said I had to use them all in one go."
