"John? Sherlock? Could you come down and help the new tenant with her things?" Mrs. Hudson called up to the boys in 221B before turning to the slight, red-headed woman with over-sized glasses "They'll be down in a moment."

Serenity wrote in her green notebook she had with her *I'm sure that I can text my brother to have some of his friends come help.*

Mrs. Hudson laughed "Dear me, no! Those two can do anything that you'll need help with."

Sherlock and John came down the stairs and John said "Hi, my name's John Watson. So you're moving into 221C?"

She wrote *Yes, I'm the new tenant. My name's Serra Brooke.*

John's eyebrows shot up in surprise "Why can't you talk?"

She smiled shyly as she rubbed her neck before replying *I was born with a defective voice box. I can hear perfectly well and do not want to be treated like an invalid.*

Sherlock peered over John's shoulder before looking at her face. "Do I know you?"

*Not that I know of, what's your name Stranger?*

"Sherlock Holmes. I could've sworn that I've met you before. Maybe with darker hair and no glasses... Forgive my ramblings, I believe that you need our help with moving into your flat?"

John looked at his flat-mate in wonder at how nice he was being to a complete stranger, although she did seem very similar to someone he knew, but couldn't quite place.

Serenity motioned for them to follow her to the moving lorry in front of the building. She gestured to the large furniture as she grabbed one of the boxes and cheerfully smiled as she made her way back to 221C. Sherlock looked at each other, shrugged before rolling up their sleeves and began moving her furniture into her flat.

After a few hours the flat was filled with assembled furniture placed where it should be and the appliances were where they should be to make the flat feel like a home. A month before, Moriarty paid for the damp and mildew to be removed and a new paint-scheme for the flat as part of his contract for Serenity getting the flat. Serenity chose a scheme of pale lilac and lavender purples to make her feel happy and safe.

A two weeks later Serenity finally put the last of the moving boxes away, she had officially moved in and put the finishing touch of lilac scented beeswax candles in all of her rooms. She smiled before picking up her purse and notebook before going upstairs to knock on the door of 221B.

"Serra! What a surprise."John exclaimed after opening the door.

Serenity opened her notebook and showed him what she'd written earlier *I'm sick of takeout Chinese. I need some real food. Would you mind helping me get to the market? I don't know where the closest one is.*

"Sure, what do you need?"

She turned the page and showed him her list.

"We can't walk all of that home, we'll have to take a cab." he pointed out.

*I have a cart*

"Ok. I'll grab my coat. I'll just be a minute." John walked to his room.

Serenity walked into the apartment, and faced the window. She remembered Moriarty whisper "If you don't put the envelope somewhere they can find it, I'll kill your brother slowly, and right before his death I'll tell him who you are." She walked over and opened it before dropping the envelope on the floor beneath it. She turned around and walked down the stairs to wait for John.

When he walked down the steps, he smiled a boyish smile and said "So, where's this cart of your's?"

She walked over to the alley next to the flat and unlocked a blue wooden cart with fairly well sized wheels. They walked to the market and bought everything on her list before heading back to Baker Street. John chatted to Serenity as they walked back, she smiled and laughed with her facial expressions at seeing her boyfriend happier than he was when she first moved in.

When they neared 221 Baker Street, John saw the shiny, black BMW and said "Great, His Majesty, Mycroft Holmes, Sherlock's elder brother and the physical embodiment of the British government has deigned to speak with us peasants. He can wait until I help you put all this away."

They went down to 221 C and John helped Serenity put everything away where it should be. They walked over to the alley and locked up her cart before returning to 221. John walked up the stairs to 221 B and Serenity went into the kitchen and helped Mrs. Hudson.

Minutes later John stormed down and roughly grabbed Serenity's wrist and pulled her up the stairs behind him into 221 B. He threw her into the center of the room, stormed over to the table where the envelope now laid and brought it over and shoved it in front of her while saying "Why the hell did you put this letter underneath the window, hmm?" he seethed as Mycroft ans Sherlock glared at her.

She pulled out her notebook *If I tell you, then my family will die.*

Mycroft asked her with his voice dangerously quiet "Who hired you?"

She snorted *Moriarty owns me. I'm his puppet, his plaything. I don't know any of his plans or games.* her eyes begging them to believe her as she handed her notebook to them.

"I believe her." Sherlock quietly stated as Mycroft and John turned to him. "She's an innocent with a past that she wishes she didn't have, a twin that either doesn't know she exists or hasn't met her, yet she protects him or her, and a secret that she has to keep. Leave her be, Mycroft. She's only trying to protect her own family, just like we are trying to find ours. Serra's done nothing wrong." Sherlock said the last sentence while looking at Serenity with kind, sad eyes.

Serenity silently cried as she wrote *Thank you Sherlock.* she handed it to him with tears running down her face.

Sherlock read it silently before replying "You're welcome."

She ran across the room and cried into his shirt with her arms around his torso in a hug. He stiffened for a moment before tentatively holding her close while smoothing down her wild, red curls. He shushed and rocked her in place as she continued to silently sobbed into his shirt for over a minute. He glared at Mycroft with a look that meant death if he ever upset his friend Serra like this ever again. He gently disengaged her from his shirt and guided her over to the couch and sat down with her before grabbing her shoulders and saying "Serra, Look at me." he commanded. Serenity looked up at him "I won't ever judge you for your actions concerning Moriarty holding the life of your family over your head. Neither will John or Mycroft. You will always be safe and welcome here."

John sat down next to her on the other side and gave her a hug while saying "I'm sorry I was mad at you. I just thought that you were a mindless plant of Moriarty's to distract us. Please forgive me?"

Serenity nodded. She grabbed her notebook and asked *What's in the envelope?*

Mycroft opened it and read it aloud "This is your only clue. It has the answer if you think about it.

With hair of flames and a heart of gold, She waits for the trio to bring her home.

With no voice, she lives in silence.

She expresses more with her eyes than a thousand words and her heart is visible to those who can see.

But without a voice who will recognize the little mermaid on dry land?

What is her real name and where is she from? She lives below, yet she's high above.

Her love doesn't recognize her and calls her by another name.

It hurts her, yet she plays the game.

If she's not recognized within two year's time, she'll return to the sea as foam and never be found.

The twin who knows suffers in silence, while the other will want to see her before the end.

The days tick by, the hours fly.

Who is she?

What is the story that she hides?"
