SPOILER WARNINGS: Will have spoilers from season 4, yes, even though it is set before that. Also I must apologise if some deductions are not 100% fact, I'm just an amateur. I do not own any of the BBC Sherlock characters. Rachel Ashworth is my OC. In the future, I hope I will be able to recreate some Sherlock deductions and have spent quite some time researching so please enjoy.

A feminine hand reached for the door knocker. After 3 quick raps on the door, the voice of a elderly lady could be heard before the door handle twisted and the door was pulled open. Immediately, the cold winter air flooded the corridor, causing the land lady to wrap her wrinkled fingers around her polkadot blouse covered arms. "Good morning. Are you Mrs Hudson?" The girl at the door asked, her eyes surveying the wallpaper and the state of the stained carpeted floor before looking into the eyes of the lovely old woman before her. "Oh, and you must be Rachel," Mrs Hudson responded, moving her hands away from her arms to receive the visitor at the door. "We have been waiting for you, come in dear it's rather cold isn't it out there." The girl stepped in, the sound of her boots hitting the carpet echoed against the almost tattered wall. Mrs Hudson stepped back, reaching to close the door of 221B.

Rachel stood in the corridor; it split into 2 directions: one, slightly to the right, lead to a door which would be assumed to be the land lady's room, the other direction was a flight of 10 steps which then continued and led to the floor above the cafe next door. The slight jingle of keys for the door on the side of the corridor below the stairs could be heard before Mrs Hudson moved besides the girl. Above the door frame, a rusty sign with the symbols "221E" could be seen. "I'm really glad that someone decided to take this room dear." The elderly woman said as she unlocked the two locks on the door. "It's the basement so it isn't very popular, I managed to get the black mould out recently but the wall paper is only going to be fixed next week." The door opened to a flight of stairs leading down to the room.

"The two women entered the room, rays of sunlight speckled the boxes piled in the center of the beige carpeted floor. "Well dear, I hope you enjoy your new room and get busy unpacking, I would ask the two boys upstairs to help you but I'm afraid the only nice one has gone out and the other won't move from his chair at the moment. Besides the risk of black mould I would say this flat you could get at this price." Removing two replica keys she announced," Well here are your keys dear. I'll be upstairs if you need anything." Mrs Hudson stated as she turned to leave. "If you don't mind me asking," Rachel started,"the which day will someone come in to fix the wallpaper?" After an answer from Mrs Hudson she continued," and area doesn't have any risk of illegal consumption and trade of dru-?" Her last sentence however was cut off as Mrs Hudson closed the door. Rachel turned back to her mound of boxes, sighed and headed up the stairs, leaving the furniture and other objects to sit a while longer in the boxes.

This is only a intro chapter so it's only 500+ words long. I don't know how long it will take to write a new chapter but if this gets even a little bit of attention, I will try.
