"Why are you being so quiet? Is something wrong? Tell me there's nothing wrong." Amy Pond demanded, eyeing The Doctor suspiciously as he flitted around the control panel of the TARDIS, pushing buttons and pulling knobs furiously.

"No, nothing. Wrong, I mean. Nothing's wrong- perfectly fine." The Doctor said distractedly, staring at a few symbols that were currently blinking on one of the screens in front of him.

"Does it have to do with that man? The one you were talking to earlier when you thought I wasn't paying attention?" Any asked, crossing her arms and raising her eyebrows.

"Yes, actually!" The Doctor exclaimed, turning around to face her. "I owe him a favor and it seems as if he's chosen now to cash it in."

"What kind of favor?" Amy asked warily as The Doctor went back to the controls.

"Sherlock Holmes- ever heard of him?"

"Maybe. Is that who you were talking to? The tall, gorgeous bloke?" Amy smirked.

"Gorgeous?" The Doctor glanced back at her. "Er, well, he is rather tall, I suppose. Either way, he needs our help. Well, my help, but I think you'll be necessary for this to work in the first place. You can use your 'womanly charm'." He pulled a large lever before turning back to Amy, a wide grin on his face.

"Womanly charm? No, wait. What are we doing?" She leaned forward, eyebrows furrowed.

"Don't look so worried!" The Doctor laughed, dismissing her worry with a casual wave of his hand. "Mr. Holmes has just requested we pay his friend a visit."

"What kind of visit?"

"A friendly one!" he smiled, glancing at the screen once again before looking back to Amy. "Now let's go! 221B Baker Street, London, England!" He practically skipped to the door, Amy following closely behind. He opened the door, revealing a rainy London street at midday, people milling about with large umbrellas.

"Baker Street." She murmured, stepping out of the TARDIS and pulling her jacket tight around her middle. "Sounds familiar."

"Yes, I bet so!" He responded before turning around and walking down the street quickly, leaving Amy to catch up with her companion. "Come along, Pond!" he called, slightly bending his head down against the wind. He and Amy walked alongside each other silently, stopping in front of a big, black door with a brass 221B fixed to it.

"This is it, then?" Amy asked as The Doctor gave the door a few loud knocks.

"221B Baker Street, current residence of-" he paused as the door opened slowly, revealing a short man with blonde and gray hair, leaning on an aluminium cane. "Doctor John H. Watson."
