The Doctor was bored. He had been locked in the concrete cell for what seemed like hours, with no companions to amuse him and no TARDIS to escape in. Thankfully, his kidnapper had left him with the contents of his pockets.

He had already attempted to escape by using the sonic screwdriver, but the cell seemed to be locked with a double deadlocked seal. He had also thought of resonating the concrete, but that might cause the cell to collapse onto him, and he was too fond of his current regeneration to let it be squished.

After fiddling with the sonic had become too boring, he dug out some food. He always carried some emergency supplies in his bigger on the inside pockets, and this had come in useful on more than one occasion. The Doctor found: one satsuma, some fish fingers in a sandwich bag, a bag of jelly babies and a jammy dodger.

Just as he was starting on the fish fingers, sadly without custard, he heard footsteps.

"Finally." The Doctor said, standing up and brushing some crumbs off his trousers. One of the concrete walls started to creak. The Doctor took a step back from it, and watched as the wall slid up a few inches, leaving a small gap.

A plate was pushed inside the cell, and the Doctor bent down to see a huge pile of his least favourite food, pears. He could hear the thing outside walking away.

"Oi!" The Doctor yelled, banging on the concrete. "Come back here and show your face, you coward!" The footsteps stopped, and slowly, menacingly, the thing returned to outside the cell, where it was formerly standing.

Last week, after he and Amy had saved London from an army of Graske, Amy had insisted on a shopping trip. In one of the DVD stores they visited, the Doctor had bought the first series of a TV show called 'Sherlock'. Amy and Rory were addicted to it, and they were planning a trip to the future to buy the next fifty-nine series.

The Doctor, mostly because he was bored, but also partly because he thought it might come in useful, decided to try and work out who had captured him from what he had seen so far.

From the way called it a coward had worked, the Doctor thought it may have been a Sontaran. But for the pears. There was no way the Sontarans would know or care about his hatred of pears. He couldn't see the cybermen or daleks playing mind games either.

The Doctor tensed as he heard a click outside the cell. This time, a sheet of glass slid down before the concrete slid upwards, to stop him from escaping. The cell must have cost a lot to build, he mused.

A pair of feet became visible, and the Doctor studied them closely. From the expensiveness and shape of the shoes, he concluded that his captor was a rich human. The concrete reached his waist, and kept rising. The man on the other side was wearing a black suit, a heavy gold watch on his right wrist. There was something strange about the watch. With a jolt, the Doctor realised that the symbols on the clock face were Gallifreyan.

The concrete vanished into the ceiling, and the Doctor found himself staring into the triumphant face of the Master.

"What?" He exclaimed, stumbling back against the concrete wall. "No!"

"Hello!" The Master said happily. "Sorry, I can't stay long, but I've got a lot going on right now-"

A huge roar suddenly shook the cell, and the Master's face momentarily looked annoyed.

"What was that?" The Doctor asked, looking behind the Master. All he could see was more concrete. The Master's delighted expression returned.

"That's my new friend." He replied, "No, not friend. Business partner." He glanced at the Gallifreyan watch. "Time's up! Bye for now." He began to walk away, taking a remote control out of his pocket and pressing a button. The concrete slid back down.

"Come back!" The Doctor yelled, questions streaming through his head. "How did you escape the time lock?"

The concrete clicked back into place, and the glass ascended.

"Answer me!" He shouted, desperate, but there was only the echo of his own voice.

Thanks for reading! I would have posted it earlier, but my internet died. The next part is about what River is getting up to...
