Chapter 1:

Sapphire sat in the black shiny jaguar refusing to get out.

"Come on Sapphire, get out the car." Sherlock said, he was starting to get annoyed with her now.

"No! I am not getting out this car! I am staying right where I am." Sapphire yelled from inside the car.

"Sapphire, get out of this car now! Stop acting like a three year old and get out now. John and I will miss our flight." Sherlock said peering inside the car. Sapphire sat and shook her head before turning her back on him. "Right, that's it. You asked for this young lady." Sherlock reached into the car and grabbed Sapphire's feet. He started pulling her out the car. Sapphire realised what he was doing and grabbed hold of the other car door.

"Sapphire let go! You are 15 and you are acting like a three year old." Sherlock said. Sapphire still refused to let go of the door. "John go to round the other side and make her let go of the door." Sherlock instructed.

John followed Sherlock's orders, making Sapphire let go of the car door. Sherlock pulled Sapphire out of the car, shutting and locking the door so she couldn't get back inside.

"Why do I have to stay here? Why can't I go with you two to America? It could be like a holiday." Sapphire moaned.

Sherlock looked at her. "Because Mrs Hudson is on holiday and I don't trust you to stay at the flat on your own. You can't come with us because; 1-we are working on a case, 2- you don't have a passport and Mycroft wouldn't get me one for you said it was bad for any country that had me and you in at the same time. Apparently Britain can only just cope."

"Yes, get all that but why do I have to stay with him?" Sapphire said.

Sherlock sighed, "Because despite how much you and I hate him, he is my brother and besides I know you will be safe here."

"I don't care if he is your brother! He hates me and I hate him. Oh yes of course I'll be safe here, look at all the security we went through just to get in! Four checkpoints! If I didn't know better I would have thought the Queen lived here." Sapphire declared.

Sherlock laughed and went and hugged Sapphire. "Well Mycroft does go over the top with his security. But it is a good thing that he is over the top with security; it means I know you are going to be safe while John and I are going to work on this case." Sherlock let go of Sapphire and back towards the car. "Please Sapphire take care of yourself and try not to kill Mycroft while I am away. No matter how much I hate him, Mummy wouldn't be pleased if she found out I let you kill Mycroft." Sherlock shut the door of the car and rolled down the window.

Sapphire stuck her hand in the window. John looked at her from the other side of the car, "It will be okay Saff, and we shouldn't be gone more than a week. Just stay out of Mycroft's way and you should be fine." John smiled.

Sapphire tried to force a smile, but was trying to hold back tears. She knew this stay would be torture and it hasn't even started yet.

Sherlock gently push Sapphire's hand out of the window. He patted it once, and then he nodded to the driver to pull off. Sherlock and John looked out the back window to see Sapphire standing at the end of Mycroft's long drive way.

Sapphire stood there waving, as the car drove off into the distance.

Sapphire stood outside the gates to Mycroft's house. She stood wondering where Mycroft was. He knew she was coming today. If he didn't turn up soon, Sapphire decided she would somehow make her way back to Baker Street. Even though Sherlock had taken her key, she would get into the flat.

She waited for a few minutes. She grabbed her suitcase and turned to leave. At that moment a car came from inside the gates. The gates opened, the car pulled out the gates and pulled up beside Sapphire.

A man in a sharp suit got out the driver's door and opened the back passenger's door for Sapphire. "Miss Doyle."

Sapphire got into the car and the door was shut behind her. She turned to her left and saw Mycroft in the seat next to her, twiddling with his umbrella. "Hello Sapphire." Mycroft mumbled refusing to look at her.

"Hello Umbrella Boy." Sapphire snarled.

The driver had put Sapphire's suitcase in the back of the car, and started the car back up. Turning it around and started to drive back up to the house. "Too lazy to walk 100ft and come get me, I thought you told Sherlock that your diet was working." Sapphire said sarcastically.

"It is working thank you very much. But I was running behind schedule, plus I thought the car would be good because of your bag. Anyway concerning your nickname for me. While you are staying with me I would like you to refrain from using it."

Sapphire slumped in her seat. "Well personally I don't wish to call you by name. And besides I don't particularly want to be here..." Sapphire snarled.

"Well the feeling is mutual. I personally don't want a child running wild in my house." Mycroft said.

Sapphire turned and scowled at Mycroft, "Just because I lived on the streets for a while does not mean I am feral. So don't assume anything."

The car pulled to a halt as they reached the house. Mycroft's side door opened, he climbed out and walked towards the front door. Sapphire followed, she got out the car and saw the house for the first time. Well if you could call it a house. This place looked more like castle. What confused Sapphire is that Mycroft lived on his own in this huge building, with its many windows and acres of land.

The driver retrieved Sapphire's bag from the boot of car and carried into the house, disappearing up the stairs and down one of the many corridors.

Mycroft looked at Sapphire, "Well are you coming in, or just going to stand there all night." Mycroft said looking back at Sapphire.

Sapphire just glared at him but then followed him inside. Mycroft lead the way through the house, Sapphire followed taking the way in to her room. On the way Mycroft went through the ground rules.

"Right the ground rules, you must obey these at all times. Rule 1- You are not allowed near my office or to disturb me if I have a client. 2- Don't disturb me full stop, I don't want to know about your petty problems..." Sapphire blocked Mycroft's droning out, just dawdled behind him. "Rule 10- Don't harass my staff, leave them be. Oh yes, Mummy is visiting tomorrow, you are to make yourself presentable, and you are to behave yourself, be polite. Wear a dress if possible; Mummy is a very traditionalist, so girls must be in dresses or skirts. She will be here at eleven, so make sure you are ready by then. "

Mycroft stopped and opened a door, "This is your room, for the duration of your stay." Sapphire passed Mycroft and entered the room, her bags placed on the floor. "I know your don't want to be here as much as I don't want you here, but please show some manners." Mycroft said looking at Sapphire.

Sapphire rolled her eyes, "I show manners to those who deserve them. At the moment, you don't deserve my manners, so whatever. Laterz." Sapphire said slamming the door shut, and locking it before Mycroft could protest against her.

Sapphire found her pyjamas, changed into them and then climbed into the giant four poster bed. She pulled out her phone and text Sherlock.

'Hope you enjoy America... Just hurry up and get home, your brother is annoying me already. I want to go home. Oh get to meet your mother tomorrow... Does she know you have an adopted daughter? - S x'

Sapphire laid thinking about how hellish this say was going to be, and Sherlock and John weren't there to keep her sane. Her phone beeped on the bedside table.

'It will be okay just stay out of Mycroft's way and you will be fine. Erm no she doesn't know, but Mycroft has probably told her. Wear a dress or skirt. Will try and be quick, can't make promises.-SH"

Sapphire sighed and put her phone back on the table. Tomorrow was going to be fun. Not.
