This is part of my doctor who series where Lily is The Doctor and River's daughter, but Lilly won't be like me anymore, we just like the same things (like Doctor Who and Sherlock), but when we end up back in London after my first adventure, why has the TARDIS brought us here? Has Sherlock Holmes got the answer hidden in a fob watch; and is there a reason Moriarty hates Sherlock so much, but can't remember?

This will not just be 3rdperson Doctor Who POV, but there will be some 3rd person Sherlock parts without The Doctor, and there will be other POV's too like Lily's and Sherlock's, maybe even The Doctor's or John's.

Lily's POV

The Doctor, River and I walked into the TARDIS after my first adventure. it had been a month since they picked me up, and we had been on the planet Zamias for the whole time. "So how did you find it, Lily?" The Doctor, my father asked me.

"It was just amazing, and that's including the Zeras" I said smirking still trying to work out everything that had recently happened.

"Good," River, my mother said pointedly, setting the TARDIS's coordinates. Just then, the TARDIS began shaking.

"River, what have you done to the TARDIS?!" The Doctor inquired with a worried expression.

"I haven't done anything. I know how to fly her, remember? I was born in here." River responded, The Doctor sighed, still not happy with the idea.

"Will you two stop arguing and sort this out? Otherwise I will!" I said, making sure I'd be heard above their shouting. For some reason I felt like I knew how to fly the TARDIS too. Maybe it was because I had seen The Doctor do it myself on TV. That was when I thought that he didn't exist. Or maybe, it was because I was the child of the child of the TARDIS. Wow, that still didn't make much sense to even me.

"Lily, you don't know how to.," River told me.

But I didn't listen, my mind just told me what to do and I pressed the switches and the leavers that would provide a safe... or maybe not so safe landing. I stepped back in shock as the TARDIS landed smoothly, only making a small wheezing sound as it came to a halt.

"How...?" River and The Doctor both wondered aloud at the same time.

I sighed. "Child of the child of the TARDIS," I paused, then mimicked my mother's voice, "Remember?" River smirked, though The Doctor still looked a little worried. He always was, or at least that was what it seemed like.

"Where are we anyway?" I asked after a few minutes of silence between the three of us.

The Doctor pulled the scanner around, "London, your time... well," he dragged out the last word, "Your time where we left you, but in London."

I sighed. I still loved my home, or what I thought my home was. I had lived there for 13 years. "Why here, Dad?"

The Doctor looked at me, "I don't know." Just then, the scanner flicked up 'The detective,' it read. The Doctor stared at it, wide eyed.

"What is it?" River asked him, seeing The Doctor's sad expression.

"An old friend of mine; apparently, but he can't be in the only one left..." He said almost in a whisper, then picked his coat up and rushed out, putting it on as he walked swiftly from the TARDIS.

"Come on, Lilly," River told me, going out of the TARDIS as well. I followed her without protest.

Meanwhile with Sherlock...

Sherlock POV

Why was John out? Why did he have to go I'm Bored. There's no case; no call from Lestrade, nothing. But I do notice the watch; that's the only thing I notice.

I can't deduct, and it annoys me. I've had it all my life, for as long as I can remember. I just can't seem to throw it away. From what I can deduct, I know: its old, it has a strange pattern, one that I have never seen before. Sometimes it glows, and I also think I hear it, though that's impossible. My concentration broke when my phone buzzed. I placed the watch back on the side of the table where I was working and picked the phone up.

Sherlock I have a case for you - GL

Excellent, I think, at least I don't have to stare at the blank watch.

What is it? – SH

Unexplained death. I don't know how or what happened. GL

Okay, I'm coming. Where? –SH

The park.- GL

I replied to the texts, then got up grabbing my coat and scarf and told John where I was so he could come after, but I hadn't noticed the watch that had started calling to me.

Bad chapter. The first part was okay, the second bad; if you have you have an alien that would kill, but you wouldn't see a reason for death pm me or leave in a review.
