It didn't take long for Mary to fall head-over-heels in love.

How could she not fall in love with John, the sweetest, kindest, most adorable room-mate a girl could ask for? A man who could make her heart turn into an Olympic gymnast from merely the sight of his knitted jumpers.

How could she not fall in love with Sherlock, the most intelligent, devastatingly handsome, consulting detective with a voice like melted chocolate and honey who can play the violin?

Well, I'll leave it to you to deduce which man had ensnared her affections. Needless to say Mary rarely left the flat with anyone but Sherlock and John, because what could possibly be better than spending a night in Baker Street with Sherlock and John? Nothing, obviously.

So, most nights she would sit up and talk to John, he was the most wonderful listener, sometimes they would stay up till two or three in the morning before they would realise that they both had work in the morning. Sherlock on the other hand seemed to have the ability to make Mary forget every single word in her vocabulary. She humiliated herself daily by stammering and muttering to him. In fact once, when John had pointed out that Sherlock was once again in the paper, she had said "You're pretty much Zac Efron". Yes, it really was that bad.

So, one Saturday, Sherlock was solving a case where all he had to go on was a piece of masking tape and a pair of cufflinks. It was child's play of course. John had been sent to investigate the cufflink manufacturer and Sherlock had suddenly decided to follow someone who he had spotted out their window.

"You there, umm…"

"Mary?"

"Right, are you doing anything right now?"

"Well I have to grade year nine's…"

"Perfect, I need you to come out with me."

"Sure."

What you need to understand here is that it is practically impossible to say no to Sherlock Holmes, especially when he looks at you with those beautiful eyes of his. So, he could have asked Mary to do pretty much anything and she would have done it. But, we'll come to that later.

So they left 221b and stared to follow the suspicious character, Mary was suffering once again from a lack of words, it was quite ridiculous that an English teacher of all people couldn't manage to keep up a conversation. But, fortunately, Sherlock, with the hopes of seeming uninterested in his suspect broke the silence.

"So, how was school yesterday?" he said, which significantly flummoxed Mary.

"I umm, I, well I started my unit on Midsummer Night's Dream with year seven."

"Fascinating," it didn't sound totally sarcastic, "and how are you finding life in London?"

"Brilliant, really brilliant, I can't tell you how much I love living with you guys."

'Was that too much?' she thought.

"Damn I think he's noticed us, quick take my hand"

So she did. She thought she might spontaneously combust. She was holding hands with Sherlock Holmes. She felt suddenly rather foolish, but also ecstatic.

They kept waking, with the fact that her hand was in Sherlock's Mary was unable to form coherent thoughts, let alone words.

"So, have you made any new friends since you've been in London?"

"Well, apart from John, Mrs. Hudson, Greg and you..."

"Me?"

"Well of course you, John said you had trouble with the f-word…"

"The f…"

"Friend! I mean, not…anyway" Mary went decidedly pink and hoped Sherlock would find something else to talk about.

"Oh no, he's looking at us again, quick."

Suddenly Sherlock had turned to face her and before she knew it he was kissing her. For a whole three seconds Mary was the happiest person on the planet, and that is a certified fact, but then she saw John, he was standing only a few meters away and he looked as though someone had punched him in the stomach, and at the sight of his pain-stricken face Mary's heart broke. Then, as quickly as it had started it was over, and Sherlock had broken away.

"Quick Mary, we're loosing him!" and he walked away from her, when she looked back John was gone, and she tried to tell herself that he wasn't sitting in that phone booth.
