Chapter 1: Found her
"Sherlock, what about these deaths then?" Mrs Hudson went on in the seemingly old fashioned apartment "7 naturally accruing deaths, all in the same area in London."
"Mrs Hudson, you wouldn't mind making me a cup coffee, would you?" Sherlock asked, not even looking up from his furious typing on the laptop.
"I would mind actuall-" Mrs Hudson began only to be interrupted.
"Great, thanks, black 2 sugars." Sherlock still didn't look up. He was searching pictures taken around the areas of the deaths. He was sure it was murder. But he didn't know how.
"He's not even listening to me" Mrs Hudson took off to make his coffee.
"But Sherlock, how can it be murder? I've got the cause of deaths here. They were all killed by a vain in their brain breaking. There is no way a person could do this without surgery, or being witnessed!" John burst through the door, his eyes filled with doubt that this was a case anyone could solve. Not even the great 'Sherlock Holmes' could solve this.
"I've got it!" Sherlock sprung up from his desk, grabbed his coat and scarf and ran out the door "Come on, John! We've got a girl to see"
John peered over at Sherlock's laptop. It was covered in pictures of holiday makers. But in the background of most pictures was a girl. She looked around 19, pink hair, ragged clothes and she wore a wool hat low over her eyes. John assumed she was part of his 'homeless network'. But he was very wrong.
"Hurry up John!" Sherlock was shouting as he ran up onto the bandstand. "Where is she?" He muttered to himself as he looked around the park. "She has to be here." Little did he know she was closer than he thought.
"Sherlock..." John said under a hushed voice, tugging at Sherlock's jacket. "Sherlock... Look" John pointed and his finger followed to a dead body on the floor. Or what looked like she was sleeping. John knew better, her chest wasn't rising. She was dead.
"What John?!" Sherlock almost screamed. He earned a few looks before he realised the body on the floor.
They both ran towards it. John instantly took her pulse as Sherlock observed, trying to deduce as much as he can about the victim.
"She fell while walking, only visible injuries are from the fall." Sherlock mused to himself.
"Why am I even here?!" John asked, annoyed that Sherlock was looking on the medical side of things. That was what John was for.
"Shhh" Sherlock hushed John
"Why-"
"Shhhhhh!" Sherlock pressed his finger onto John's lips. "The park has become very quite. No?"
John looked up and the park was now empty. Now that he thought about it, the only other people in the park were a couple walking their dog and a girl. It was... It was that girl!
"Sherlock..." John whispered, he could see a dog running around from behind the trees. The dogs owners weren't there.
"Yeah, I know"
They both rose up, to see a dead couple around the other side of the trees. They too fell while walking. On the bench was a girl. She looked sad, insecure.
