TARDISTARDISTARDISTARDIS

The TARDIS clanked and wheezed as they fell through space. The Doctor fought with the console as sparks flashed in the semi-darkness and smoke billowed around him.

"Oh no you don't!" He cried and whacked the panel with his shoe. The ship continued to spiral through space and time not even noticing that it had been hit. The Doctor threw himself across the controls and punched the buttons until the creaky sounds of materialization echoed through the room. "That's better, what got into you?" Understandably there was no reply. "Where are we?" He wondered aloud, he ran over to the computer screen hanging precariously from its stand. Running a hand through his spiky brown hair he peered at the screen.

"London, 2010!" He liked London, it was full of hustle and bustle and there was always something going on. He raced over to the hat stand and snatched his coat off it with a flourish. Unfortunately it also meant that he knocked it over and the clatter rang through the control room. "Oops!" Always in a rush, more haste less speed and all that. As he crouched down to pick it up the room shook.

The sensation was like a miniature earthquake; the supports shuddered and cracked; debris that the Doctor knew he should've cleaned out came tumbling down around him. He curled up in a ball under the meagre protection of one of the twisty things that held up his roof until the shockwave passed. Slowly he uncurled himself. What had happened? Then he jumped up and sprinted to the door while the TARDIS repaired herself behind him.

No longer grinning he flung them open and stopped dead at the sight that met his eyes.

There was no London. The Doctor fell back into the TARDIS, he couldn't believe it. He felt a rush of fear, what could have done this? The grating dematerialisation sounds echoed and faded with the brilliant blue box. All that was left was smoke curling into the black radioactive sky above the still and silent London.

It started like an average day for George Cowley. However it didn't stay that way.

Small niggles were haunting the back of his mind and kept popping up at the most inappropriate moments. First of all when he was signing the expense chits he got to the end and found himself reaching for another one. He had the strangest feeling that he had to sign one or two more. Then he remembered; he had slipped into thinking that Bodie was still alive.

Poor lad, he had only been following orders but Murphy hadn't gotten in fast enough. He had been shot dead. He shook his head to clear it, it had been his orders and the man had followed them until the end. He had a girl too, he'd had to go and explain to her what had happened. No next of kin to inform. Cowley swallowed, there were still feelings of guilt lurking inside him but there was nothing he could've done.

That would explain the strange slip-ups, but Cowley still found himself – for example – when he was briefing the agents expecting to see more people than there actually was. It had happened three months ago! Or when he sent Bodie to his death he'd called Murphy 'Doyle'. Who was Doyle? He shrugged inwardly and checked the clock. Maybe he needed an early night. However it was nearly eleven o'clock when he finally dragged himself home with vague worries scratching at his mind.

TARDISTARDISTARDISTARDIS

"Nothing!" the Doctor flung another old book away, before proceeding to the next one. The TARDIS was being strangely unresponsive but the Doctor was closer to finding the answer than he realised! With a distracted and frustrated sigh he checked through the shelves again. They were all neatly categorised in alphabetical order which was hampering his search somewhat. Suddenly he had an idea! He sprinted to an ancient-looking computer, (a gift, so he couldn't really get rid of it could he?) he'd planned to someday but he'd never thought of the thing as useful so he'd hooked it up to the library and left it. If he tried anything with it, it would probably explode. Now… hurriedly he stabbed at the cobwebby buttons and watched as the shelves blurred and the books rearranged themselves by year. As they became clear so did the date. "Oh..."
