Welcome to the beginning of my first official Melodyverse tale for BBC Sherlock. Within this story, I introduce the little sister of Mycroft and Sherlock Holmes, Melody, as they join them for the first case of A Study In Pink. Read on!

Prologue

The plucking of the guitar strings grated on Sherlock's ears like a drill against concrete. It wasn't often he could be distracted but the person playing the guitar had a rather annoying talent for it. He looked away from his severed hand in the box to the young black-haired woman sitting cross legged in the corner of the lab, her headphones blocking out all other sound that the song blaring in her ears. She had her eyes closed whilst playing the guitar fluently to the tune in her head- a little trick she liked to do when she felt like showing off. It impressed everyone that saw her... well, everyone except her big brothers.

Melody Holmes bore a striking resemblance to her second eldest brother. Her raven black hair seemed to highlight her pale white skin. If it sparkled in the sun, she could be a Cullen, as the idiot Anderson once said to her. She merely remarked that if he shaved once in a while, he would look more human and less gorilla. The next day, Anderson's face was as smooth as a baby's bottom. Melody's smugness knew no bounds, another trait which she shared with her older brothers. Mother had always told her that it was unbecoming of a woman, but Melody ignored that. She never let her gender confine her. Otherwise, where was the fun?

Sherlock sighed irritably. Shouting was useless. He noticed the apple sitting on the table next to his hand- Molly had brought that up for him about 3 hours ago. Without hesitation, Sherlock grabbed the apple and pegged it in the direction of his little sister. And, as usual, she fluidly reached up and grabbed the apple when it was just an inch away from hitting her square in the face. The song interrupted, Melody opened her eyes, her gray blue eyes staring at her brother's identical ones.

"Is that really necessary, Sherlock?" Melody raised an eyebrow

Sherlock turned back to his hand, "Must you placate yourself with that irritating racket? I am working"

"It appeases me, brother, and unlike you with that violin, I can actually play a tune which is delightful to most ears" Melody took off her headphones, turning off her I-pod, "Besides, it helps me think"

"Oh, really? What about?" Sherlock sounded remotely uninterested. Ignoring his tone, Melody continued.

"That unexplainable bruising on the corpse. I was just curious... how long after death do you believe bodies still bruise?"

Sherlock turned and stared at Melody. Uninterrupted, Melody continued her explanation.

"What if the bruises were a post-mortem result of how the body was dumped and had absolutely no connection to cause of death? If that's the case..."

"And the body was disposed of at least an hour after his death..." Sherlock continued, realisation dawning.

"Then the heir has no alibi" Melody nodded.

Sherlock stared at his little sister, "Brilliant, Mel! Brilliant!"

Excitedly, he jumped off his stool and headed straight to his jacket, lying on the chair on the other side of the room. Melody smiled to herself as she watched her brother scramble for his mobile like a kid at Christmas. Mycroft was never this much fun. He would call his assistant, 'Anthea', and she would do all the work. Mycroft just pushes a button with his umbrella tip and tells her to 'go'. That's why, when Melody moved out of the family home, she came straight to Sherlock. With him, everything was exciting.

"Molly? It's Sherlock Holmes. Do you have anybody that has died very, very recently? At least within the last hour or so?" Sherlock paused. Melody's grin grew as she watched his eyes light up, "Brilliant! I will be right down!"

Sherlock hung up and began to hurriedly put on his jacket, "Fantastic, Melody! Maybe that torture device has some purpose after all"

Melody rolled her eyes and took her brother's trenchcoat off the other chair and helped him put it on, "Everything in this world has a purpose, Sherry. You just have to be open-minded enough to see it"

"Alright, let's get going!" With that, Sherlock headed straight out the door.

Melody sighed as she began to slowly put on her black leather jacket and put her guitar back into its casing. She untangled her headphones, placing them around her neck and had her I-pod in her pocket at the ready. She began to count down in her head, leaning against the table, twirling an object in her slender fingers.

"3...2...1..." Melody breathed, "And... cue Sherlock"

At that moment, Sherlock popped his head back in the room, looking a little flustered as if he had been running, "Mel... have you-?"

"Looking for this?" Sherlock narrowed his eyes at the riding crop Melody had twirling in her hands, her eyes dancing with amusement.

He quickly relieved her of the crop, "Come on, Melody. Time is ticking! The more we wait, the smaller the window gets! Let's move!"

His enthusiasm was infectious. Melody followed him out the door, running for the staircase- there was no time for elevators- and following her brother all the way down to the morgue about three floors down. She didn't stop smiling all the way down. Life with Sherlock was better than a rollercoaster ride. But every now and then, the rollercoaster has to just cruise, without the dreaded possibility that you'll get - gasp - bored! That balance hadn't yet been achieved in Melody's life. However, unbeknownst to them, the events of this day would trigger a catalyst in which Melody and Sherlock's lives would be changed forever...

Hope you enjoyed it!

Oh, yeah, rate, review, I no own so you no sue. The usual crap.
