Chapter 1 - And it begins…

It wasn't the first time that things exploded at 221B and John had a feeling that it wouldn't be the last either.

It all started two weeks before; Sherlock was worse than ever, for, the week before, The Doctor had told them about the Private Book Collection. Since then there had been over 10 explosions only on 221B Baker Street.

Sherlock Holmes and John Watson stood before the building, a men came behind them, warping a orange blanket Sherlock's shoulders.

"Still don't know why they keep on putting this stupid blanket" Sherlock voice showed how annoyed he was.

"You know Lestrade keeps telling them to do that, don't you?" Asked John. Anderson came towards the two of them, his face held a even more annoyed expression than usual.

"Lestrade wants to talk to the two of you" His voice was full of anger. The two men slowly got up and followed Anderson across the street and into a old house was owned by an old man that didn't like the John and Sherlock. Sherlock stopped and turned around throwing the orange blanket across the street to the place they had been sitting just a couple seconds before.

"… They can help?" A male voice asked.

"American, military and probably older than he looks" Sherlock said casually, under his breath.

"Unfortunately, they are the best then we are" Lestrade was standing with both hands behind his back, his back was erect and he was facing the tall American, who was taller than Sherlock (who isn't that tall anyways). The American was wearing a light blue oxford and black trousers, he was also wearing a pair of dark brown suspenders and a long navy blue WWII coat.

"Are they really that good?" The American asked, his eyes locked with Sherlock the moment he and John walked into the room. "I mean, I need really good people"

"They are" Director Inspector Lestrade said "The two of them are better than an entire Scotland Yard team" His hands went to his pockets, Lestrade couldn't quite stay put. Hating to have to send Sherlock Holmes and John Watson to solve the case and not a official Scotland Yard team. It didn't make sense to him why the mam wasn't with his own team, he obviously had a team for he said he worked better in a team than solo.

"Two? You said that it was team!" The American gave a step forward, his voice angry "A full team."

"I'm sorry I didn't tell you that the team was only two people, but they are the best two people for the job, Jack"

"Don't call me Jack, for you, D.I. Lestrade, is Captain Harkness" Captain Jack Harkness walked away heading towards a door at the back of the room.

"Bloody Torchwood" Lestrade murmured under his breath. He walked towards Sherlock "Captain Harkness wants the two of you to help him with a case that is apparently too complicated to all of the Scotland Yard team."

"Alright" Said Sherlock his voice cool and calm, his hands were behind his back and his eyes did not once leave the wooden door Captain Jack had just been through. "We're going to talk to Captain Jack" He started to walk away, heading to the same door that he had been staring so hard at.

John nodded, his hands stuffed inside his trousers pockets, and started walking behind Sherlock to the room. Inside there were shelves and shelves of books, but the shelves were all empty. There wasn't a single book in the whole room. The huge room had nothing but book shelves.

"What are your names?" The Captain asked.

"Sherlock Holmes and John Watson" John answered staring at the Captain's eyes. Sherlock gave a step forward, looking up and down at the Captain.

"Who are you, Captain Jack Harkness" Curiosity overtook Sherlock and before he could stop himself the question had already been asked.

"Jack Harkness, pleasure to meet you both" Jack said with a small wink.

"I'm not interested, Captain, and I'm fairly sure that John isn't either. So don't even bother to have sex with us Captain." Sherlock replied calmly to the silent question. "But back to the matter, who are you and what do you need our help for?"

"Well as I have already said before, I'm Jack Harkness and about the case…" Jack looked around at the various curious Police officers that were not quite paying attention to their jobs and instead were paying attention at their conversation. "Do you guys know any place that we could have a private conversation at?"

"Yes I do, in fact" Sherlock said already turning around and walking away. John was used to this kind of behaviour but Jack was obviously not. "I know that you're used to give orders instead of receiving them but this time you're not going to be bossing people around Captain."

Jack did not hesitate to follow the two of them after what Sherlock said. After a couple minutes of walking a about 20 different streets Jack looked up from his shoes and said to John "Are you sure he knows where he is taking us? We've already passed several restaurants and about twenty different streets."

"Don't worry Captain. He knows London by heart." A couple more minutes went by until the trio came to a stop in front of a small Italian restaurant. They ordered a table and waited until a waiter came and sat the three of them down. "So Captain Jack, what is this case about?"

"A… friend… of mine told me about this case and told me to call D.I. Lestrade and ask for his best people. So I guess the two of you are his best team." Jack looked both ways making sure that there was no one eavesdropping them. "So, about two weeks ago, the police got a call from this private book collector and he told them that his collection of over twenty thousand books went missing. The police didn't believe him, they just thought that it was a prank but it ended up being a serious case and the thief sent an anonymous letter saying that he wouldn't give the books back until the collector was dead and since then the old man has been receiving hundreds of threats."

"Would your… friend… happen to be" Sherlock lowered his voice looking at the man before him. "The Doctor?"

So this is my first full fic, it'll have around 10 chapters and it's a sequel to Same Place, Same Guy, New Problems. Tell me what you think, and what you think that will happen.
