A/N: Alright, I just really want to write a mystery and have John and Sherlock solve it. Very badly want to. Warning: I see John and Sherlock as very close friends, therefore, there will be no shipping of Johnlock. Deal with it.
John's POV:
I could already hear the vibrant violin playing from the upstairs window as I jumped out of the taxi with groceries in hand. I paid the cabbie and looked up. Sherlock stared distantly out the window as the bow moved rhythmically on the violin.
"Cup of tea would be grand." I said to Mrs. Hudson who was shuffling through the newspaper at her door.
"I'm your landlady, not your housekeeper, dear." She reminded me as my footsteps pounded up the stairs.
The violin sounded louder when I pushed the door open. Without turning around, Sherlock paused his playing to only ask who called.
"Sherlock, the phone's not ringing."
"It was fifteen minutes ago."
"Oh lord, I went out half an hour ago!" I put the milk and eggs in the refrigerator, being careful of the specimens that were cooling in a tuber ware jar.
"Well, who called?" Sherlock set the violin down and sprawled on the couch. I checked the voicemail messages.
"Sherlock, there's been a murder at the library. It's quite peculiar and there's a message. I'm not sure but… You'd better come down." Lestrade's voice echoed out the address and a you'd-better-hurry tone.
"Detective Lestrade." I said and Sherlock jerked his head towards me.
"What does he want?"
"There's a new murder."
"Beautiful!" Sherlock announced and jumped up from the couch. He spun around on his heel once before retreating to his bedroom in the back. "Grab your jacket, John Watson. We have somewhere to be!"
I threw on my overcoat over my button up plaid shirt and Sherlock was already at the door.
"I have your tea."
"Not now Mrs. Hudson, murder is in the air!" Sherlock sang from the stairs below. I passed her on the way down the stairs. The old woman sighed and retreated back into her flat, the tray of tea still in her arms.
"Thanks anyways, Mrs. Hudson." I called back to her and met Sherlock at the curbside. He already hailed a cab. He slid into the cab and I sat down next to him. The cabbie started the car and headed towards the address I told him.
"There's been a murder, it's peculiar, and there's a message."
"Did Lestrade say anything else?"
"No." I said and looked out the window. It had started drizzling outside and the cab splashed a puddle of water on a bicyclist. I looked at Sherlock but he was absorbed with his phone.
Once we reached the library, it had already been sectioned off by yellow police tape. I paid the cabbie and we walked side by side to the front door. I had to take longer strides to match the detectives long legs.
"Freak's here, bringing him in." I heard Donovan say into a walkie-talkie. We walked into the library and Lestrade stepped inline with us.
"56 year old female. Found this morning a few hours ago. Cause of death is a poison that is unknown. Anderson has confirmed that the blood loss is post-modem."
"And the message?" I asked.
"It's a handprint in a child's book. A handprint of the woman's blood." Sally said.
"Ahh… Interesting." Sherlock mused and pulled ahead of Sally's pace. He walked quickly into the child's section but someone caught my arm. It was Mycroft.
"John, I…"
"Mycroft, what are you doing here?" I asked. The older man ran a hand over his face and looked white. "Are you alright?"
"For now, quite. But I'm not sure Sherlock is." He looked at the busy children's section where Sherlock had just disappeared to. There were policemen bustling about, taking evidence bags in and out.
"What-" I stopped myself when Sherlock appeared at my side. He looked whiter than usual and his arms were crossed, he gazed at the floor with empty eyes. "Sherlock, what is it?" Mycroft looked up at him with a saddened expression.
"Our mother." Sherlock said.
A/N: Alright, so I don't really know where I'm taking this just yet but I want to have some fun with Sherlock and John! Have a wonderful day! My summer is finally here. Today was the last day and I'm loving it!
