It was cold. Colder than Sherlock had ever known London to be. But he strode confidently down the streets a sad twinkle in his eye. He was exhausted and looked as if he was about to drop. His hand grasped around John's phone that sat in his pocket. It was the only thing that gave him comfort in this cold night.

He paused, looking around his surroundings before carrying on down the Thames. Every girl had died around this area and not just because this was where they haunted. It was where the killer lived.

Two officers passed him. It was PC Myers and a young woman. Sherlock contemplated for a moment shouting at Myers, but he couldn't. It wasn't his fault. Myers was tucking a bottle of water into his jacket pocket.

Then it hit him

Of course. It made sense.

Everything connected.

That was it.

Sherlock looked up and raced towards PC Myers. He pulled the man around and punched him in the nose.

…

My phone was missing. Again.

I had torn Sherlock's room apart looking for it - I knew he took it. Instead of finding my phone, I had found an LG Cookie. Not mine, not Sherlock's. I tapped the screen. It was Sabrina's, I knew this because her wallpaper was one of her and Sherlock together a few years ago.

I looked through her messages – nothing interesting. Was it a contract phone? No… I tapped the memos. There was one that was password protected. I dismissed it. Probably dates when she needed to get her nails redone.

The phone rang. "Mrs Hudson? Could you get that please?"

The phone stopped ringing abruptly and I heard Mrs Hudson speaking silently into the receiver. I kicked over Sherlock's bed tipping the mess over.

"John!" She cried. "The mess you've made!"

I turned, she was looking at Sherlock's room. She held the phone in her hand. "What is it?" I asked, sighing.

"It's Inspector Lestrade," She said. "Something's wrong with Sherlock,"

"Tell me something I don't know," I muttered. I took the phone and stumbled down to the living room, clutching my bandages. "Hello?"

"Get here now,"

"Why?"

"Sherlock has gone insane,"

"He's always been insane,"

"Would you just get down here? He attacked Officer Myers,"

"Okay, I'm coming,"

….

"I'm not insane,"

"Sherlock, you attacked an officer!" I replied.

"He had it coming,"

"Sherlock!"

"What? I did what I had to do,"

"What was that?"

Sherlock looked up at me "I kinda… hit him…"

"Yeah, I got as much," I said. "Assaulting an officer is a criminal offence, you can get done for it!"

"I took that wholly into consideration," Sherlock replied, sipping silently on his coffee.

"I don't think you did," I replied, folding my arms. "Can you tell me your reasoning behind it all?"

"He did it,"

"Adam Myers did it? Officer Adam Myers?"

"I know it sounds insane,"

"Did you deduce that on your own or did you need Lestrade's help?" I asked.

"But it makes sense," Sherlock replied.

The door opened and Lestrade stepped inside. "He's not going to press charges," He said. "Thank god," He folded his arms looking at the young detective.

"Don't look at me like that," Sherlock said.

"I assume you had reasons other than pure grief," Lestrade said. "And you better make them flawless otherwise I might have reason to place charges on you,"

"Add them to the list," Sherlock snapped.

"Sherlock!" He cried. "Will you please understand the seriousness of this all? I'm sick of trying to explain the complications of the human emotion to you. Now, tell me why you hit him."

"He did it," Sherlock said simply.

"I'll suspend my disbelief for a moment," Lestrade said. "How?"

"Haven't figured it out yet,"

"But you just know it's him?"

"Of course I do,"

"Sherlock!" I said. He looked at me with his sharp eyes. I sighed and tucked my hands into my pocket. "Run us through the reasoning behind the idea,"

"It's not an idea," Sherlock snapped. "It's fact."

"And you always have proof to support fact," I said. "What led you to think-?"

Sherlock sighed. "You, John said yourself in the draft of your blog that you saw a drop of water on Sabrina's chin,"

"Meaning nothing," I shrugged.

"Myers had a bottle of water tonight and on the night he killed Sabrina," Sherlock concluded.

"He might just get thirsty on the job," Lestrade said. "You have nothing to link him to the other murders,"

"Was Myers on beat those nights?" Sherlock asked.

"Most of them are,"

Sherlock smiled confidently.

"No," I said. "This is madness. Sherlock, I think you're just looking for a quick fix,"

"I said so myself. It's someone they would have known, someone they would have trusted even though they are complete strangers, much like the Taxi drivers. We expect them to care for us when we're drunk or what not,"

"Would you listen to what you're saying?" Lestrade barked. "These are my officers you're talking about! If I knew they been committing these acts I would have had them tossed into jail in an instant!"

"But that's the thing!" Sherlock said earnestly. "He's smart!"

"More," I said.

"Beg your pardon?" Sherlock asked.

"Give us some more evidence," I said.

Sherlock looked over at me. "Alright," He said. He dropped his head and began to pace, his hands behind his back. He stopped after a few minutes. "When you were talking to Alistair-" He said.

"Alistair?" I asked.

"Surely you couldn't have forgotten him!" Sherlock said. "Works as the CCTV monitor at Mycroft's institution. Worse bad habits than me…"

"Oh yeah," I said shuddering at the thought of uncut dreadlocks.

"He said that the police come around to help him monitor. One stayed with him in the security room whilst the other passed through the halls unnoticed with a security pass,"

I thought about it for a moment. "Yeah, but still Sherlock," I said.

"John," He said. "I know it was him. It wasn't Keith,"

"You need more proof," Lestrade said.

Sherlock paced for a few more minutes. He stopped. "What was her name?" He asked.

"Who's name?" Lestrade asked.

"The officer that was with Myers tonight," Sherlock said.

"I dunno,"

"Isn't she on your team?" Sherlock asked.

"Sherlock, he didn't come in with another officer," Lestrade said.

Sherlock looked away, his eyes dark. He threw his coffee to the ground and stormed out of the room. Lestrade and I looked at each other for a moment.

"Is the room to Myers locked?" I asked.

"No,"

We stood there for a few more seconds, before bounding out after Sherlock. Lestrade flung open the door and we saw Sherlock pushing Myers against the wall, his nostrils flaring. "Who was she?" He roared.

"Sherlock!" I shouted.

"Who was she?" Sherlock bellowed.

"There was no one!" Myers struggled against Sherlock's strength. "I swear, I was on my own tonight!"

"You lie!"

I grabbed Sherlock pulling him away from Myers. Lestrade helped the officer up. "I swear," He gasped. "I was alone tonight,"

"Sherlock," I said. "Are you alright?"

Sherlock looked over at me. He shook his head. "No… I'm not alright."

Please review, many and mucho thanks.
