My husband and I Watched all 3 Seasons of Sherlock in 2 days which got me addicted. That led me to read some fan fiction (as I always do when I get addicted to something) But I was overall disappointed with everyone seeming to either slash John and Sherlock together or shipping Molly with Sherlock which honestly didn't work for me either. So I spent a few days thinking of what type of woman would I expect to see with a man like Sherlock Holmes in real life. About an hour of typing and this gem popped on my screen.

That being said nothing belongs to me, except Ava. She is the creation of my evil mind waiting to to wicked things.

Chapter 1 – Hard to Explain

The doorbell rung at 221B Baker Street and because of the commotion in the flat concluding the recent resurrection of Moriarty nobody thought anything of it. Until the shrill scream from Mrs. Hudson's mouth echoed up the stairs. John Watson wasted no time racing down the stairs followed by Detective Inspector Lestrade.

"She was just here John! Out of nowhere! Gave me such a fright, is she still alive?" Mrs Hudson said frantically. John leaned town and carefully searched for a pulse. Taking in the sight before him. Young woman mid to late 20's bound, gagged, blind folded, and unconscious.

"She seems alright Mrs Hudson. Greg, help me get her upstairs please so I can take a better look?" Mrs Hudson sighed in relief as she followed the men back inside and up the stairs. Everyone took sight at the 'parcel' left on the doorstep and cleared off the settee. The men gingerly laid the woman down and went to unbinding her. When they took the bind fold off, Mary made a loud gasp from behind John.

"Ava?" Mary rushed forward now examining the woman her own way. "Oh my god John it IS Ava!" John was crouched down by his pregnant wife concerned and confused.

"Am I supposed to know Ava?" John asked. Mary adjusted her position so she could be more comfortable.

"I'm sorry, she's just my little sister." She said with tears in her eyes cradling the woman's limp hand against her cheek. John gave his wife a quick hug and proceeded to examine his now VIP patient.

Until now Sherlock Holmes had been lurking by the fireplace watching the scene unfold in front of him while Mycroft was being his usual Bureaucratic self sitting in a chair with his laptop on his knee and phone at his ear. As John was examining Ava, Sherlock took the opportunity to gather his findings as well. He was about to speak when dark green eyes fluttered open and looked right into his for a split second and he nearly forgot to breathe, just nearly though when her eyes quickly scanned the room and landed on Mary.

"It's yo.." *coughing, "water" she croaked as she gingerly sat upright. Lestrad was back right away with a glass filled and handed it over. After she took a couple of large gulps she finally spoke again.

"I guess it's over then? Either Moriarty has been caught or I'm in play am I correct?" She looked directly at Sherlock this time as she spoke.

"Yes Moriarty has been apprehended for the time being." Sherlock stated, "Were you aware of your role in his game?"

"Not at all, but if you don't mind I'd like a moment." She turned her attention to Mary who was silently crying still. "I'm so happy to see you sis...15 years is too long don't you think?" She lightly chucked and helped Mary into the seat with her and embraced her tightly. Introductions were made and as the girls caught up over tea and biscuits courtesy of Mrs. Hudson, Sherlock found himself listening to Ava intently as her story was revealed. Graduated high school at 17 with a full scholarship to MIT only to drop out 3 months later to attend Harvard pre-med, switch to literary major then drop out a year later to attend culinary school in New York City. Working her way through restaurants to buy a food truck and doing Amateur MMA matches in her free time. Sherlock deduced that not only was she intelligent beyond most people, but like himself, she found most people and things dull because she was hardly ever challenged.

At that he finally began to appraise her physically. She had blonde hair like Mary's braided down past her shoulders. Large dark green eyes, high cheek bones, and full lips. Perfectly in proportion to her round face. She was an inch taller than Mary who stood at 5'5, and her slim muscular build held womanly curves that some women would pay big money for a surgeon to try and replicate. With that, for the first time since Irene Adler, Sherlock Holmes was intrigued by a woman. The hour was late and with Mrs. Hudson, Lestrade, and Mycroft Holmes returned to their respective homes, or wherever they chose to dwell at this late hour, Mary and John were discussing accommodations for Ava when Sherlock finally joined the conversation again.

"The only logical conclusion is for Ava to stay here for the foreseeable future."

Ava was the only one in the room not stunned into silence.

"Only if it's amenable to you Sherlock. I will do my best to stay out of your way for however long I stay." She replied.

John begun to speak. "Um.. are yo.."

"I'll stop you right there John." then she stood up and looked at Sherlock. "High-functioning sociopath?" she asked.

"Yes." He replied simply. Mary sat back and giggled as John sat stunned. He had begun to ask how when she interrupted him instantly.

"He sat back in his own home appearing bored even though he was carefully listening and keeping track of the conversation. He was even checking me out for a moment."She looked at Sherlock for a moment and remarked, "Bad boy." She then walked over to the skull on the mantle and spoke again. "He also spent a good long time staring at this skull while fidgeting his index finger which told me he was a smoker and that this," she lifted the skull, "was his cigarette stash." She picked up the pack and pulled one out and lit it with the lighter that was with it and took a deep drag and sighed in relief as she tossed the pack to Sherlock to which he did the same.

"I'll be fine John, perfectly fine. Mary If you don't mind bringing me some clothes and some groceries tomorrow evening I'll cook us all some dinner. Just bring some random stuff... I like being surprised. Now I..."

Sherlock interrupted confidently, "Bathroom is the first door on the left. Dressing gown on the back of the door. When you get out I'll find you something suitable to wear to bed."

She gave him a sly seductive smile and then kissed him on the cheek saying thank you before saying goodbye to her sister and her new brother in-law and leaving for her bath.

When John and Mary left for their car John finally said, "Now I see why you like Sherlock. He reminds you of her." She gave her husband a kiss on the cheek. And laughed softly "Wait til you get to know her." She said as he started the car and drove off. "She's a hard thing to explain."
