*4 Years ago*

Her eyes scanned the room below, eyes the only thing visible through her balaclava, watching as the dignitaries below went about their business of lies and honeyed words, observing the beautiful dresses of the women and the finely tailored suits of the men as continued to search out her target. She envied them all their ignorance to the world, to the blood and tears that were her everyday life.

"Such pretty things will never be mine… A monster has no need for them"

Her words were barely a whisper as she located her target and prepared the sniper rifle, checking around her once more for a clear escape route before turning her full attention back and pulling the trigger without hesitation. A perfect shot through the skull.

The next moments were chaos, perfect for her escape as she moved swiftly through the rafters of the old manor, listening as the screams of those once carefree noble ladies filled her ears and the shouts of the men made her smile. Yes, welcome to a little piece of her world.

"Quite the assassin you are, but we were tipped of your plans this morning. Believe me, Morte, this shall be your final mission"

She stopped in her tracks, not turning to face the smooth voice that beckoned behind her. She had her serrated blade and her hand gun, she held no fear for a fight if that was what it came too. Even without her weaponry, they would be no match for her.

"I trust then, that you know I have disposed of the snitch… Mr. Mycroft Holmes. The man behind the British government. A pure blooded genius in every sense of the word, but if I know of you then I am certain that you know more of me than my alias"

His haughty scoff sent a jolt of irritation through her, turning her head slightly to register that him, taking an extra moment to appreciate the proud man before her, his figure defined by a snug looking three-piece suit and his soft looking ginger hair neatly combed back, he was clearly a man of fine taste and impeccable grooming. They appeared to be alone. Wrong, her eyes scanned the area she had managed to reach, an attic apparently. There were three men hidden within the shadows, each heavily armed. Such fun prospects humans could be.

"Known as Morte, your true name has been lost to you. A mercenary of the highest quality who only receives the highest payments, you have yet to fail on a mission. But your success ends here my dear. You shall be coming with me. Detain her"

It's as if she's watching the clumsy oafs he commands run in slow motion as they attempted to charge at her, her own moves fluid and graceful as she flicks out the serrated switch blade from her hip holster, an emptiness within her eyes as she swipes it through the throat of the first man before sending a solid high kick to the face of the second, sending him flying backwards with a bloodied nose and unconsciousness rapidly setting in, knowing that shards of his nasal bone will have been forced upwards and into the brain. It's the third that attempts a surprise attack as he shoots her thigh, attempting to incapacitate her.

She grunts at the pain but returns the favour of a bullet, hitting the centre of his skull perfectly, just like before, and watching as he drops to the floor, his life force fading fast as she turns back to the man once more, both seeming as if nothing has happened, both not acknowledging that her death count has moved up a further three as she smiles sweetly and draws his attention to the thigh that had been shot.

"Here be monsters Mr. Holmes"

For a moment, his eyes appear to widen in shock as the gaping wound marring her flesh begins to stitch back together, the grotesque sound of the muscle and skin tissue pulling and melding itself back into its previous state enough to turn the stomach of even the strongest men as she swipes at the blood with a tissue and flings it towards him.

"I'm sure you will find your answers in Baskerville, my handsome friend, their experiments and test subjects have gone beyond that of monkeys and beagles"

She was gone before he could get a word in, her escape route pulled off at last as she disappeared into the night and left him with the bodies of his men and a monumental mess in the ball room below. His mobile was in his hand in an instant as he sought the answers he now craved.

"Anthea, organise an inspection of Baskerville at the soonest convenience. It appears their curiosity has taken a dangerous turn"

It was the last thing she heard as she finally disappeared into the busy streets below, a smile on her lips as she heard the commotion continue behind her.

*Present day*

Her thoughts were cut short as the feel of her knife slicing through her index finger snapped her back to the present and she remembered that she was no longer in the field, registering that the kitchen of her tiny apartment was where she now stood as she brought the damaged finger to eye level and watched thoughtfully as the skin became flawless once more, nothing more than a trail of drying blood left behind to prove that she had ever injured herself, a soft smile pulling at her lips as she whispered to herself.

"Some ghosts truly can't be laid to rest"
