Okay! I like this idea for a story, and have wanted to try it for awhile. Constructive criticism is welcome, but please take into account that I'm fairly new to this and most of the writing is done on my phone. Here goes...The whole story will be written in the P.o.V of my O.C., Tia.

Disclaimer: I do not own Sherlock. Or London. Or a guinea pig...

Warnings: Minor swearing.


Tia Hudson did not entirely understand what the word 'eccentric' meant. She was a 24 year old lady living in the 21st century; she didn't need to know things like that. After using Google (See? 21st century.), she found that it was another word for a very odd and unique person.

Tia's aunt, Martha Hudson, had asked her to come and 'take care of her flats' while she was away visiting family for a few weeks. Tia, being the sweet person she was, agreed to the... whatever it was. The more her aunt talked, the more she was convinced that it had been a bad idea.

However cowardly it was, she had almost told the cabby to turn around several times now. That probably wasn't a good thing, but Tia couldn't bring herself to care.

As the cab came closer and closer to 221 Baker Street, Tia began to feel anxiety build up in her chest. She swallowed and pulled out the small mirror that she kept in her purse and looked at her reflection. It looked the same as it always did; messy red hair pulled back in a ponytail and bright green eyes shining behind thin-framed glasses. Tia never wore much makeup, but she wanted to look presentable to whoever her aunt's tenants were. Deciding that she looked good enough, Tia put the mirror back in her purse and looked out the window.

To her right was some place called Speedy's, and to her left was her aunt's place. The cab stopped, so she grabbed her bags and got out. Walking over to the door of her aunt's flat, Tia knocked the knocker.

Martha Hudson opened the door with so much excitement and joy that Tia struggled to keep a straight face. She laughed on the inside and followed her aunt inside.

"Oh, put your bags down there, dear. I'll get Sherlock to bring them up in a minute- oh, speaking of, he's the one I told you about," Mrs. Hudson raved.

Tia contained her laughter and her joy at seeing her aunt again.

"The 'eccentric' one?" Tia asked, her forest green eyes sparkling.

"Yes. He... well, you'll see. We could go up and meet him now, if you like."

Okay then, Tia thought. My eccentric aunt talking about an eccentric guy.

"Sure, Aunt Martha," Tia said. "That'd be great."

Mrs. Hudson nodded sharply and led the way to 221B.

Tia half expected some guy with a weird mustache and half a clown costume on. She did not expect... well, Sherlock.

Aunt Martha led the way up the stairs, limping on her bad hip.

"Sherlock, dear!" she called. "I've brought my niece- the one I told you about. Do try to be nice, please?"

Upon entering the flat, Tia was encountered with a mess. Things were lying everywhere- papers, dishes with unknown substances, and... a gun?

Lying on the sofa with his hands in a steeple under his chin was a man. He seemed young, but she couldn't tell for sure. He wore a blue dressing gown over messy clothes. His hair was dark, and his eyes were closed.

"No, Mrs. Hudson, I have no recollection. Must have deleted it," Sherlock said. "You don't happen to have any liquid nitrogen on you, perhaps?"

"Some what?" Mrs. Hudson asked. "No, dear. I just wanted you to meet Tia. Please don't-"

Sherlock jumped gracefully into a sitting position, his eyes now open. They were a startling light greenish gray. Both Tia and Martha Hudson jumped slightly.

"Well, she's an online college student with two cats at home, a white one and a tabby. Father was absent, mother was an artist. Abusive boyfriend... broke up with him not long ago. Fairly small friend group... I'd say four, maybe five, but likes to socialize. Was close with her grandmother until her untimely death. No siblings. Doesn't travel much, is nearsighted, enjoys reading and-"

"Sherlock, I think that's enough, dear," Mrs. Hudson said with a small voice.

Sherlock blinked.

Tia was staring in shock. He was right on every single point... there was just no way that he could know all of that.

Her aunt fixed Sherlock with a hard look and said sternly, "Say you're sorry, dear."

Sherlock blinked again. "But I'm not," he said, seemingly completely confused.

Tia kept staring.

There was an uncomfortable silence in the room for awhile until finally Sherlock spoke again.

"Did I get everything right?" he asked.

Tia was usually a very patient and controlled person. She dealt with what she had formerly considered as impossible people with relative ease due to her laid back personality. Sherlock, however, crossed the line. Not only had he invaded into her personal life, but he had also displayed less acceptable manners. Tia Hudson was, to say the least, less than pleased.

"Who the hell do you think you are!?" she snapped.

"Language, dear," her aunt whispered softly as Sherlock just stared at her blankly.

"So I was right, then," he said. It wasn't a question.

Her tolerance for his quirks ended there. Who does he think he is? she thought. She carefully regained her composure before speaking again.

"Yes," Tia hissed, "You were bloody right. I'm sorry, Aunt Martha, but-"

"Well, I did warn you, dear."

"-But I don't think I can tolerate this. In fact, I think it's hazardous to your health to be living with a psychopathic stalker, don't you?"

"Sherlock isn't a stalker, dear."

Emotions coursed through her faster than she could identify them. Her aunt was living with a psycho. She was supposed to take care of said psycho while her aunt was away. Tia snapped. She didn't mean to, especially not at Aunt Martha, but this crossed the line.

"Oh, really!? You heard what he just said! How the hell could he have known that without being a fudging psychopathic stalker?"

"Your necklace."

Both of them turned to Sherlock, who was watching them. He seemed bemused and... bored. Yes, he definitely found their completely civil conversation boring. Go figure.

"What about my necklace?" Tia asked, clutching the heart-shaped silver locket.

"It was a gift from your grandmother. See the engraving? 'To Tia, From Grandma Jane. I'll be with you in your heart forever.' Can't get much more obvious than that. So, you and this Grandma Jane figure were close. Consider the words: 'I'll be with you in your heart forever.' She knew that she was going to die, so she had the locket made as a keepsake for you." He made a face. "Sentiment. Disgusting. Anyhow, it's quite new, so there's your untimely death.''

Tia glared. "Yes, she died of cancer about seven months ago. How'd you know about my cats?"

"Simple: There's cat fur on our clothes. Two different colors-two cats. I know they're yours because you would have been on a train all day yesterday and have changed clothes. Therefore you brought the animals with as well."

"Yes, and there's nothing you can do about it," Tia snapped, an idea coming to her. She had promised her aunt that she'd take care of the flats. So, she would, and she'd give the insufferable psycho a hard time in the process, starting with the location of the litter boxes. She had seen his obvious dislike for cats instantly.

Sherlock rolled his eyes.

"How'd you know about everything else?' Tia asked. Now she was only asking to get on his nerves.

That plan failed. If anything, he seemed excited to. Just as he was about to ramble off some more stupid excuses for stalking, Mrs. Hudson interrupted.

"Well, now that you know each other, I'd best be off. Tia, make yourself at home in my flat. Disregard any stupid rules Sherlock sets about cleaning, just do what's on the list. There isn't much. Sherlock, behave, and be a dear and carry out my bags? Then bring in Tia's."

"High-functioning sociopath," Sherlock said.

"What?" Tia asked.

"You called me a psychopath. I'm a high-functioning sociopath," he said. With a final bone-chilling glare sent in Tia's direction, he went off to do as told.

Tia went down to settle into her aunt's flat, wondering what she had gotten herself into.


A/N: I usually hate O.C.s. They seem to be either overpowered, the center of attention, or just don't fit in with the story. However, I am making an exception because this seems like a neat plot. As for updating, I have no schedule, so... yeah. I doubt this will be good as I'm still new to this, but I'll do my best.

Thanks!
