She walked down the busy London street, people were passing by quickly, she strolled leisurely in her beautiful dark blue Victorian dress. Her long black hair was up in a messy but stylish fixture that had a few curls trailing loose. Many men who passed her spared time to look and show her some unwanted attention, but she simply glared at them menacingly before gracefully continuing down the street. She had managed to leave the Torchwood premises on the promise that despite being based elsewhere she would still carry out jobs for them. They had given her a comfortable sum of money and found and bought a place for her to stay, although they warned if she were to ignore any request by them, they wouldn't hesitate in bringing her back and into a cell. She had managed her freedom, through a few years of good work and invaluable advice, with the addition of some persuasion from a friend of hers and current co-worker, Captain Jack Harkness. Now she was looking for her new place of residency and a little more freedom in her life, which was something of a luxury for her.

She reached the house in which she was to be staying as arranged by Torchwood, it was 221B Baker street. There was a convenience as a previous tenant had just moved out, leaving a vacancy. The other people still living there was the landlady, Mrs Hudson and one tenant, a rather unique detective. Not that this was of any interest to herself or Torchwood.

Arianna walked up to the black door and knocked loudly. Before long a pleasant looking woman, wearing rather plain clothes opened the door. Arianna could see that she was obviously not too well off judging by her attire, yet her posture was strong and she wore a necklace that denoted some wealth. She was a widow perhaps, left to look after a property she couldn't afford by herself, which would mean she was the landlady, Mrs Hudson. Of course it only took Arianna a couple of seconds to notice this.

"How may I help you dear?" Mrs Hudson asked.

"I'm Arianna Smith, you must be Mrs Hudson?" Arianna asked politely.

"Why yes, I am." Mrs Hudson smiled sweetly. "Do come in, it's a pleasure to meet you Miss Smith."

"Please, it's just Arianna, and the pleasure is all mine." Arianna smiled a little before following the woman inside.

"Well, let's show you to your room." Mrs Hudson walked up the long staircase with Arianna behind, she opened the door to a room to find several furniture and books already there neatly. "Well here we are, your things are all here, they were sent before you, and right through here is all your clothes." Mrs Hudson indicated to a wardrobe.

"Thank you, it looks delightful." Arianna replied.

"Your welcome dear, now there's no set time for meals, but cook and the maids can bring them up whenever you want, if you don't say it shall be around 8:30 for breakfast, 1:00 for lunch and 6:30 for dinner. All meals will be served downstairs in the dinning room, however if you don't venture downstairs I'm sure the maid's will bring it too you. Oh, and do feel free to ask me or any of the staff for anything you need dear." Mrs Hudson smiled again.

"Of course, thank you, there is one thing. I hear that there is another tenant here? Is that correct?" Arianna asked. She was terribly polite; she had to make sure she complied with the correct image for a lady in the Victorian era on Earth.

"Yes there is, dear. A Mr. Sherlock Holmes. I'll introduce you to him, but I must warn you that he is a little… eccentric." Mrs Hudson searched for the right word to describe him.

"Ah, I see. Not to worry, my father was among many things, eccentric." Arianna said thoughtfully.

Mrs Hudson nodded and lead her to a door down the hall. She paused before knocking and entering the room. As soon as she entered, she coughed furiously through all the smoke that filled the air. She waltzed over to the window and opened letting most of the smoke out.

"Mr Holmes! Honestly, how can you breathe?" Mrs Hudson said angrily.

"Quite easily actually, Nanny." Holmes replied.

Mrs Hudson came to stand next to Arianna who was surveying the mess that was Holmes' room with amusement.

"Sorry for his state, dear. I would like to say he's not always like this, but, he is." She whispered.

"I heard that Nanny, and I'm not in any state, I'm in the process of a scientific breakthrough." Holmes replied whilst hunched over his many apparatus.

"Right, well there's someone here I'd like you to meet." Mrs Hudson said.

Holmes made no replied and instead he carried on fiddling with various flasks and such as if they weren't even in the room.

"Mr Holmes." Mrs Hudson said authoritatively.

Holmes turned around, his face displayed and obvious silent protest.

"This is Miss Arianna Smith. She is our new tenant." Mrs Hudson said gesturing towards Arianna who nodded slightly.

Holmes stood up and moved closer towards her.

"A lady alone?" He enquired.

"A working woman." Arianna simply replied.

"A working woman that can afford to rent?" Holmes asked suspiciously.

"My job is quite well paid."

Holmes raised his eyebrow slightly but said no more on the subject.

Mrs Hudson cleared her throat. "Yes, well I must be going now, please try to get along you two."

Arianna smiled a 'thanks' to her but watched as she left the room. By this time Holmes was already back near his make-shift laboratory. Arianna walked over to him quietly.

"May I see?" She asked.

Holmes looked up but said nothing as he backed away.

"Hmm, what have we here?" Arianna asked to herself. "I smell… Diethylamine," She paused "and acyl chloride, no wait chlorinated acyl chloride. Must be Chloroacetyl chloride." She looked up and at Holmes who was trying to suppress his surprise.

"What exactly are you trying to do, that would accumulate to a scientific breakthrough?" She asked.

"I'm working on a new anaesthetic." He said as he sat down in an arm chair and lit his pipe.

"Well, you've got a little way to go yet." She smiled, "But I'm impressed."

"You're impressed?" Holmes raised his eyebrows. "I'm the one who is more entitled to be impressed."

"And are you?" She asked, a smile playing at her lips.

"Yes, quite." He replied whilst smoking his pipe. "Please take a seat, Miss Smith."

"Thank you, but please call me Arianna." She replied as she found herself a seat.

"Where did you learn about such sophisticated science?" Holmes asked.

"At school, where else would one learn such things?"

Holmes smiled a little, a mischievous glint formed in his eye.

"I have never come across a woman with such knowledge." Holmes said.

"Well then, perhaps you have many things yet to learn Mr. Holmes." Arianna grinned cheekily.

"Please, it's Sherlock." He replied. "So what do you do for a living Arianna."

Arianna smiled at his use of her first name, he had remembered from earlier.

"I do much the same thing as yourself, investigating, deducting, and on occasion, aiding the law."

"I see, only on occasion." He smiled.

Arianna laughed, "Well, there's no fun in always following orders."

"You're quite right there."
