Okay then, here we go again :)

In A Study In Pink, the Cabbie says "There's a name. That no-one says. And I ain't gonna say it, neither."

Hands up if you shouted Voldemort at the TV. *Guiltily puts hand up*

Disclaimer: I wish I owned Benedict Cumberbatch, but I don't. *dayumm* Neither do I own Amy Pond, Sherlock, Doctor Who or any other BBC stuffs metioned here :p

"No!" Amy wailed, sinking to the floor in floods of tears. Sherlock spun round, his face void of emotion.

"This means something to you?" he asked, calm and collected as always. Amy couldn't contain her grief. Clutching the union-jack pillow to her heaving chest, she poured out her story to Sherlock – growing up in Leadworth and one night meeting the raggedy Doctor. The endless trips to psychiatrists, all ending with her biting them. Then, encountering the Doctor again and travelling with him and Rory through time and space. How she and Rory had taken a break from the adventures for a while, staying in a luxury hotel in Central London. How they had bumped into a 'client' from Amy's kissogram days. How Rory had stormed out of the hotel bar, texting three day s later to inform Amy he was back in Leadworth with his parents, but that she shouldn't come looking for him, as he needed time to think. Sherlock listened intently, never moving, never looking away from Amy, and never making even the slightest sound. Finally, Amy finished and wiped at her eyes.

"You probably think I'm mad, and that it all sounds impossible." She sniffed. Sherlock smiled.

"Not at all. When you have eliminated the impossible, whatever remains, however improbable, must be the truth." He brushed a tear away from Amy's cheek.

"I like to think that nothing is impossible" he whispered. Amy glanced up.

"Whoever this is sending the messages, he has done something to the Doctor. We need to find him. Anything could happen without the Doctor. He has saved so many lives, so many times – we owe it to him. I owe it to him." She stared at the floor, desperately trying to think of the next move they should make. Eventually however, exhaustion overpowered her and she sank into a restless sleep.

Amy woke up to the sound of Sherlock's voice. He was stood at the window speaking on his mobile phone, silhouetted in the early morning light.

"I need this information Mycroft, and you are the only person I know with this authority…yes…Torchwood won't speak to me…Harkness thinks I'm an arrogant sod…oh very funny. Just…just help me this once, Mycroft. Text me." He hung up, glancing over his shoulder at Amy.

"Good morning. My brother is trying to get me some information regarding the Doctor's whereabouts. Now, you'll be wanting some breakfast i suppose?"

Half an hour later, Sherlock and Amy sat in the quiet café underneath 221B, Sherlock staring intently out of the window, Amy sipping delicately at a steaming mug of tea.

"Sherlock? When you said this person had left puzzles for you before? What happened?" Sherlock sighed wearily.

"As I said, it happened about a year ago. There was a man who went unnamed for a long time, because people were too scared to mention his name –"

"Oh my god – Voldemort?" Amy giggled. Sherlock gave an icy stare back.

"You know, Voldemort? From Harry Potter? He-Who-Must-Not-Be-Named?" Amy looked slightly guilty at having interrupted. Sherlock imply rolled his eyes and continued.

"His name was Moriarty. He was the brains behind a lot of the cases I was working to solve around that time. Eventually, I solved the cases he alerted me to and met him at a swimming pool in East London. He had strapped a vest full of Semtex to my…my colleague" Sherlock's eyes had turned cold and detached. Clearly the memories were painful.

"I thought we were safe. But he came back. And I shot at the bomb vest. John saved my life – he pushed me into the pool. But he took the full force of the explosion." He trailed off, a single tear falling into his coffee. Amy placed her hand over his sympathetically.

Sherlock phone vibrated noisily in his jacket pocket. Retrieving it, he looked at the screen, a smile breaking on his pale features.

Torchwood have just detected rift activity in the Baker Street area. Keep an eye out. MH.

Sherlock smiled, turning the screen to show Amy. Before she could speak, an eerie screeching sound filled the air. Amy eyes glowed with happiness, and she ran outside just in time to see the familiar blue police box materialise in the middle of the road. The door opened with a creak, and the Doctor stepped out, wearing a distinctly non-blood stained bow tie, and looking just as he always did. At the sight of his expression however, Amy's heart dropped. His eyes were filled with sadness, and his face didn't bear the usual confident grin.

"The Master. He's here. The Master is on Earth. Again"

Reviews would be appreciated :)

P.S. Did you spot a hidden clue in Chapter 2? Or did the bow-tie distract you?
