Prologue

Sherlock looked up at a distant noise. Somehow he knew this noise even though he had only heard it twice before. The first time had been when he was only 5 years old. And then only once again when he was a teenager, around 18. But the noise was never a bad thing, it mostly meant hope for anyone who heard it. Even in the darkest of times, that noise meant light.

"Am I the only one who hears that terrible sound?" Dr. John Watson asked, looking around completely confused.

"Shall I go investigate?" Sherlock questioned, a smile covering his bow-like lips. "Even the smallest of noises can tell you everything you need to know." Without so much as another word, he raced off through the large building. He climbed the stairs two at a time, his heart beginning to race. "Doctor! Doctor!" There was a flashing light shining on the hallway wall from an open door, and the sound of a key scraping across a piano string stopped. "Doctor!"

Sherlock pushed the door open further and gazed after a large blue phone box that had the word police scrawled across the top. Sherlock couldn't help but let out a laugh as he moved towards the box. The door opened and out stepped a man, shorter than the last. He had brown hair that fell into his grey eyes. He was wearing a red bow tie, a nice shirt with a dress jacket, and nice black pants with suspenders.

"Doctor?" Sherlock asked questionably.

"So this is where I've landed, is it?" the man smiled and held out his hand. "Sherlock Holmes. London's greatest detective." Sherlock took the bowties hand and pulled the man into a hug.

"New face again?"

"I've had worse, can't argue."

"What brings you here this time, Doctor?" Sherlock stepped back, one of the largest smiles he'd ever worn on his face growing more as he looked at the man closer. "Your nose!"

"Again." The Doctor clapped his hands together. "I've had worse. At least it's not the ears and the leather."

"Or the eyes and the trench coat." Both laughed. "Oh, it's good to have you back Doctor. Here! Come look at the latest murder. It's a wonderful piece." Sherlock moved from the room, hardly noticing the two passengers who had also stepped from the big blue box.

"Let's crack on!" the Doctor said, moving after the detective. The two others raced after the Doctor but stopped where he had on the stairs just moments before.

"Where are we?" a scottish voice asked, belonging to a red haired, green eyed woman.

"London, Dear Amelia Pond." The Doctor started for the next floor down, two up from the mysterious, curly haired sleuth.

"And when are we?" another questioned, this one coming from a brown haired, grey eyed man.

"Rory, do keep up," The Doctor rolled his eyes and turned, causing both Amy and Rory to act as an accordion, coming to a halt up against each other. "2016-2017, give or take a few minutes. Not far from your time I believe." The Doctor turned again and began for the next set of stairs, passing a large mirror on his way down. At a scream from Amy, the Doctor stopped. "Yes?"

"Your-Your-Your-" She stuttered, completely terrified by something she had seen.

"Your reflection's backwards." Rory finished for his wife, as he rubbed her arms soothingly. The Doctor turned to look at himself, but only saw the back of his head. "Ah, yes." He nodded, wringing his hands. "We're in a different universe. Both of your mirror images will be the same. No harm done."

"That would explain Mr. Sherlock Holmes," Rory pointed out.

Amy nodded, finally getting a hold of herself. "I loved those books. Mum used to read them to me when I was a child."

"Yes," The Doctor turned to face his companions, "Sherlock Holmes is one of my oldest friends, you see. But here, in this universe, he exists but the books do not."

From far below, a couple floors, came the impatient voice of Sherlock, "if you're quite finished, Doctor, I need you down here!"

"Coming!" The Doctor called. "So, rules! Number one!" They all continued down the long spiraling staircase, "Do not mention the books. If someone from this world were to find out about them than this world would form its own paradox. Number two! If you want to avoid being called stupid, then don't say anything at all." The Doctor spun around, making Amy and Rory stumble again. "Especially you, Rory." He added at the end before disappearing into another doorway.
