A/N: I have an exam tomorrow, so naturally I'm writing a Sherlock Doctor Who crossover fic. This ones a bit weird though, and not very final yet, and this is just the first chapter but do tell me if I have got them in character.

So, yes, basically the eleventh Doctor and Sherlock. Early Sherlock timeline, late Eleven timeline, before Trenzalore obviously. A bit too much to write but what the hey I have too much to study and negative motivation.

Read and review. Please.

Disclaimer: Oh I wish I owned them both.

'And here we are, Clara!' The Doctor paused, cracking the door open and sticking his head out only to look back in and frown.

'What is it Doctor?' Clara asked, taking a step back. She knew too well about the several levels of danger the Doctor could've landed the Tardis in and the last thing she wanted was to be near the door.

'Where are we, Doctor?' She asked again to which the Doctor made the face of a five year old who had been denied his favourite toy.

'London.' He said in utter disgust, opening the door fully and walking out while still grumbling. He raised his wrist and squinted at his watch, 'March, the 11th, 2010! Why! Why here? Why now? What's so special about today? For once can't you actually take me where I want to go?' He turned around on his heels and looked back at the Tardis, sitting there in all her blue might, its blue doors closed to the outside world, effectively hiding the fact that it was more than a thousand times bigger on the inside.

The Doctor glared hard at her closed doors, still grumbling about how unhelpful and unreliable the Tardis was when he noticed something. The Tardis doors were closed.

'Clara?' He called, his almost non-existent eyebrows knitted together. He walked up the Tardis and opened the door, only to find it empty. He called out again a few times, went inside to check if she was in her room, or in the library, or in any other room he could think of but she was nowhere to be seen. Stepping out he walked around the Tardis, checked the alley they had landed in, and asked a couple of people walking by if they had seen the girl but all was for naught.

'Where on Earth did you go, Clara?' the Doctor said finally after spending nearly the whole day looking for the missing girl in all the possible places he could think of. It was 7 in the evening and as the Doctor stood there sipping a smoothie outside a café, one called 'Speedy's sandwich bar and café', his desperate eyes still scanned the crowd in hopes of finding her.

'Uhm excuse me.' He said stepping directly in front of a man who barely avoided walking into the Doctor, 'Yes, sorry but uhm have you seen a girl, about this tall' he raised his hand to about where he pictured her head would have been at, 'Bubbly personality but rather boss- '

'Hang on, mate,' the man said suddenly, 'Do you, er, have her picture or something? Maybe that would help?'

'A picture.' The Doctor echoed, 'Oh how clever, yes, indeed clever. A picture. Unfortunately no, I don't have a picture of her or else I would have shown you that already.' The Doctor finished, his face a mere inches from the other man's, his delicate brows knitted together in a threatening way, well at least according to him. He waited for the man to speak up, a rather short man now that the Doctor finally got a good look at him, crossing his arms and putting on his best grumpy face as he did so.

'Er, this girl,' the man paused, his eyes shooting up to one of the windows before continuing, 'What's her name?'

'Clara Oswald. Why, do you know her?'

'No, not a clue. Em, listen –'

Minutes later the Doctor was sitting on a rather uncomfortable chair in a rather cluttered apartment, though that didn't bother him much. In front of him sat the man from before, who had introduced himself as a Dr John Watson. Next to him sat yet another man who was yet to introduce himself though he had been assured the man was his best shot at finding Clara.

'Erm, Sherlock?' John began, waking the taller man out of whatever he was in the middle of, not that John ever knew.

'Yes, missing person, is it?' Sherlock spoke up looking at the Doctor with his piercing gaze.

'Yes, that is correct, though how did you know that? I don't recall telling – '

'I saw you wandering about outside in the morning talking to random people with a distraught look on your face. It's well past seven in the evening and here you are. Missing person. Obvious.'

'Oh, clever. Yes, I see. But no, not really, I could have been searching for my dog, or a goat.' The Doctor said, shrugging, 'Goats, I've never thought of them as pets before. I think I'll keep one.'

'I –' Sherlock began, looking as though someone had just smacked him in the face. John waited for a second or two for the man to continue and on seeing that Sherlock had basically been rendered speechless, he decided to take over.

'Right, Clara Oswald.' John said, clearing his throat, 'What can you tell us about her?'

'5'2'', dark brown hair and none of this matters because you wouldn't know how she looks anyway.'

'Right, when did you see her last?' John continued, clearing his throat to make Sherlock work again.

'Oh, let's see, that would be in the Tardis. I went out first because well I had to check whether everything was alright or not and the moment I turned back she wasn't there anymore. It's like she just disappeared.' The Doctor paused, frowning more, 'She wasn't even in her room.'

'Her room? So you checked her house then?' John egged on.

'Oh, no. No! Her room! In the Tardis?' the Doctor said, a bit annoyed.

'The tardis.' John echoed, looking confused as he glanced at Sherlock who was sitting with his hands on his lips, as if he was praying. He cleared his throat and said, 'Sherlock?'

'Hmm…' the detective finally spoke, 'Right, missing girl. Gone the moment you turned around near a place called Tardis?'

'My Tardis is not a place! It's a uhm…' the Doctor paused, looking at the two men in front of him, one eyeing him in perplexed and unsure sort of way while the other stared at him through sharp, unblinking eyes, while he decided whether to tell them about his blue time machine or not.

The fact of the matter was that he needed to find Clara and after having spent almost the whole day looking for her he had found no clues, not even extra-terrestrial ones that could lead him to her, and honestly he needed all the help he could get, even if it was from the two men sitting in front of him right now.

'Yes, yes it is a… dimension. Yes. Place.' The Doctor rose from his chair deciding that he had had enough of sitting and began to walk about in what little room he had, 'Its park-… I mean it's a couple of blocks away and I've looked everywhere within a 5 mile radius from here…'

'And you haven't found a thing. Well you won't find anything if you don't know where to look.' Sherlock cut in, getting off his chair and joining the Doctor resulting in John, who was sitting on his low chair, having to crane his neck up to look at the two tall men walking about the small apartment.

'A small-ish girl, missing within seconds of you seeing her, from right behind you-'

'Did I say girl? Forget that I said girl. Clara would be furious if she heard that-'

'Right, a woman then, a woman, gone missing the moment you take your eyes off her and no trace of her since.'

'Have you tried her mobile phone?' John offered to which both men halted abruptly and faced him.

'Of course! Her mobile phone! How could I have not thought that! How clever! Well, of course I tried her bloody mobile phone. Even tried homing in on the signal.' The Doctor said, turning away in disdain.

'Anything?' Sherlock asked, turning towards him.

'No, nothing at all.' For a while there was silence in the while as the three men pondered on this new bit of information when suddenly the Doctor did a tiny leap and twirled right into a surprised Sherlock.

'Oh lovely. So many different signals all around, it was bound to take some time. But look!' the Doctor held up his flashing screwdriver, 'It's found her!'

'What the devil is that?' John put in, joining the two men who were gathered around what looked like a screwdriver's handle with a weird light on top and a metallic claw.

'Well, what does it look like? It's a sonic screw driver!' the Doctor said like it was the most obvious thing in the world.

'A what?' John said but quietened down as Sherlock all but placed his hand on John's mouth, silencing him, and stared at the sonic.

'Fascinating.' Sherlock chanted as he stepped closer, a mere inches away from the glowing device.

'Yes, I know. I know. Fascinating and clever. Very clever. Now! This way!' And suddenly John found himself trying to desperately catch up to the two men who seemed to be in their own league, their long strides leaving John gasping as his short ones tried their best to catch up.

What in the blazes, John thought, trying his best to not get cross with his new flatmate.

After what seemed like hours of running through countless alleys and street the strange man with the bow tie suddenly stopped, with Sherlock stopping just behind him followed by a panting John. They surveyed their surroundings; the sonic seemed to have lead them to a dead end.

'I don't understand.' The Doctor spoke up, pointing the sonic here and there, frantic eyes searching for any traces of Clara.

'Well, at least we know where her mobile phone is.' Sherlock said almost on cue holding up Clara's phone. He handed it to the Doctor who took it in his hand and held the sonic near it. A few seconds later he flicked it, much to John's surprise when the claw opened, and began shaking his head.

'What is it? What's wrong?' John asked, 'Is this not her phone?'

'Yes. No. Yes. What? No, no a very good copy but no.' the Doctor trailed off as he began pointing the sonic in several directions, flicking it now and then.

'What do you mean a good copy? From what I can tell your device picked up on the signal given off by Clara's phone, from this phone. Even if it were a copy there was no way-'

'Yes, clever, except this...' The Doctor pointed the sonic at the phone and held it there until the phone turned into a strange device that didn't look like it belonged to this planet, 'Perception filter. This device was programmed to emit the same signals emitted by Clara's phone. The sonic took a while to detect the signals because that was how long they took to set this device up.'

'What is that thing?' John asked, noticing how quiet Sherlock had gotten again.

'Something that doesn't belong here by several billion miles.' The Doctor said, his voice turning grave all of a sudden. He then turned on his heels, his coat swinging behind him and headed off into the dark.

'Come along boys, I don't think this is going to be that simple.'

'Oi wait up will you?' John shouted, breaking into a jog as he caught up to the man, Sherlock trailing behind him, 'And what is your name? I don't seem to recall you telling us.'

'I am,' the man with the bow tie paused and smiled, 'the Doctor.'

'Okay, doctor who?' John asked on cue, earning a giggle from the man who suddenly sped up.

'Oi! Doctor WHO?'

A/N: Doctor: Doctor who? Doctor Who? DOCTOR. WHO?

Me: Oh do shut up.

Doctor: I love it when they do that.

Me: Go away I have people to thank and beg for reviews.

Sherlock: Oh please, as if this mediocre piece of writing will ever fetch reviews. I don't even remember how I ended up here, wasn't I -

John: Yeah, ignore that. He tends to get like that at times, though honestly I'm still not used to it. And yes, please, we'll be honoured if you do review.

Me: *muffled sounds of crying in frustration*
