A/N: So… I started writing this late at night a few days ago. And I have now gone through it and elaborated and added on and fixed up what I originally wrote. Enjoy! Also, I only own a TARDIS dress and some TARDIS and Dalek socks. That is all I own of either Sherlock or Doctor Who.

Summary: I don't really know where I am going with this, so I guess I should say that this is an adventure with Sherlock, John, and the Doctor. A mysterious enemy has come to Earth and started stealing people, and, well, if you want to know more you just have to read the story.

Place in Series: Alternate Season 3 where Mary hasn't entered John's life yet. I might change this, just depends on how the story goes.

The wind gusted through the trees as John walked back to 221B Baker Street after picking up some take- out for Sherlock and him to eat while working on their newest case. It had to do with over 1000 people of different ages, genders, backgrounds, jobs, and connections disappearing around the globe in less than one month. The only things all of these disappearances had in common were the strange tracks left behind by the kidnappers at the site of the disappearance and the quickness of the disappearances... or at least that is what Sherlock told John.

Just an hour earlier Sherlock had told John to go pick up some take- out, John's choice, while he searched for anything useful in his mind palace. Of course, John agreed. Having gone through quite a few dangerous, life- threatening situations with Sherlock by his side, John would do almost anything he said. Almost, but not everything. As he left the flat after receiving the call from the Chinese take-out restaurant Sherlock and John frequented often saying that their food was almost ready, John heard Sherlock pick up the phone. So he stayed in the hallway to try to figure out who he was calling. Sherlock never called anyone; he much preferred texting any day. Sherlock then cleared his throat and said, "Doctor? It's me, Sherlock… No, I haven't called you to take you up on your offer to go to the Lost Moon of Poosh and explore… I haven't called you to tell you that your bow tie is cool, either. Because it is not cool, it just makes you look like a mixture of an old man and a child… Fine, fine. I'll take that insult, but only because I already gave you one…Doctor, I really have something rather urgent to talk to you about… Because you have been distracting me from the point of this call by asking me all of these questions!... Doctor. Doctor, listen to me. I called you because there have been some disturbances on Earth… No, not as big as the whole planet moving or anything like that. It's a smaller scale — for the moment, at least… 1000 people of different backgrounds have disappeared from the Earth in less than a month… Yes, they have a few things in common… I was about to get to it! You didn't allow me to complete my sentence! They disappeared quickly and had strange marks around the site of the disappearance… They had one more thing in common… You, Doctor. You had met them all at some time of their life… I am sorry to say that Captain Jack Harkness is one of the victims of these extraterrestrials… Yes, Doctor, give my intellect a bit of credit. Of course I know that they are extraterrestrials, what else could they be? ... After the time I spent with you, I thought I could identify them, but I can't… Please, Doctor, please say you will come and help me on this case… It is January the 28, 2014 in London, England, Earth, the Solar System… Yes, I was poking fun at you… I know, I am a bit surprised, too… Remember, 221B Baker Street… Ok, see you then."

Sherlock hung up the phone and John walked down the stairs, stunned. On his way to the Chinese take- out he mulled over what he had overheard. For one thing, he had no idea who this Doctor bloke was. How did Sherlock know him and why had he never told Sherlock about him before? Why was Sherlock saying that this case's criminals were extraterrestrials? Who was Captain Jack Harkness? Why was Sherlock asking for help on this case, from this… Doctor no less? He was still thinking about all of these things when he was walking back. Lost in his thoughts, John didn't find the higher- pitched, more- mechanical sound strange with all the whooshing of the wind. Until he saw a police box from the 1960s appear out of nowhere. A man in a tweed jacket and a bow tie stepped out of the police box and saw John standing in front the police box with his mouth open in shock.

"Oh, hello there. You must be John. Nice to meet you, I'm the Doctor," the Doctor said, shaking John's hand, "Do you know where Sherlock is?"

"I am also a doctor, you know," John said by way of introduction and confirmation, "And he is up in our flat. Come on, I'll show you in."

John was interested to learn more about this Doctor and how he knew Sherlock so well, so he ushered the Doctor in to 221 Baker Street. And up the stairs they went, John and the Doctor, up to 221B and their destiny. Little did either of them know what had happened to Sherlock while John had been out.

So, what did you think? A review would be much appreciated, and it would be equally great if you would go check out the Sherlock fic I am working on From Darkness I Awake: A Johnlock Fanfic. Thanks for reading!
