AN: Don't own Sherlock. Little one-shot. Could be more, maybe.

Dear John

Dear John,

There is no way that you're going to believe what I'm about to tell you. I'm… Well I'm pregnant. I just found out, I guess we should've been more careful since we're both doctors. I know that you'll do anything you can to help, and that's why I'm not sending this letter. You are head over heels for Sherlock Holmes and I am not ruining that. Well, I just needed to write this out.

Love,

Sarah


Dear John,

I'm sorry that I had to fire you today but I really couldn't risk you finding out about my pregnancy. And you really are unreliable, but it's only because of him.

Love,

Sarah


Dear John,

The baby kicked for the first time today. I think of you everytime it moves. If it's a boy I'm naming it John and its last name will definitely be Watson. Maybe one day I'll tell you about it.

Love,

Sarah


Dear John,

It's a girl. They told me today. I want to name her after your mum, but I forgot what you said her name was. Maybe I'll remember.

Love,

Sarah


Dear John,

You're officially a father, congratulations.

Love,

Sarah


Dear John,

She's gorgeous. I named her Hannah. Her personality gets stronger each day, and my God does it remind me of you. I saw that Sherlock jumped off of the building on the news, I'm sorry.

Love,

Sarah


Dear John,

Hannah just turned five and she's asking about you. I've told her so many magnificent stories, most of them from your blog but she won't let it rest. Hopefully one day I'll work up the courage to bring her to meet you. Hopefully you won't be mad.

Love,

Sarah


John,

I've gotten sick, I have cancer. The other doctors are saying terminal within a year. I've made it clear that once I'm gone Hannah will go to you so I'm including all of previous letters. Some things you'll need to know: She's ten. Her birthday is 16 March 2011. She likes mysteries. She likes your blog. She is a good student. She reminds me of you.

Love,

Sarah


"Hello," I said as I opened the door.

"Hi," the little girl waiting there answered back.

"What are you doing here?" I asked.

"Coming to live with my daddy, since mummy died"

"Sorry," I said, sad to be letting her down, "there are no daddys living here".

She just stared at me, as though I was supposed to realise something.

"What?" I asked.

"Maybe you should look at this," she said as she handed me a box.

I opened it up to find letters and pictures. I opened the first one; it was addressed to me and was from Sarah, informing me of her pregnancy. I invited the girl inside and looked through the rest of the box, and learning that she was my daughter, Hannah, and also my legal responsibility.

"What's that?" Sherlock said as he walked into the room, referring to the girl sitting in my chair.

"She's my daughter," I said.
