Jack, Cale and Lock rounded the corner and came face to face with Martha, Valerie, Elspeth, Riley and Cat. "Oh good," Lock said. "We found you before Cat managed to blow the place up."

"How did you get out?" Jack asked.

"Cat had a box of matches," Valerie said, rolling her eyes.

"Yeah, I know, but I didn't think Martha could pick locks." All of the girls looked at Jack like he'd gone mad.

"No, she can't. I got us out."

"You can pick locks?" Jack asked looking at her surprised.

"Uh yeah, who do you think taught him?" she pointed at Lock and Jack shrugged.

"We have to find the Doctor," Martha said. "Do you know where he was taken?"

There was a chorus of 'no's.

"Don't worry," Elspeth said. "We'll find him. We have to find our friend as well."

"Who?" Jack asked.

"Little Jack. We tried calling her Jackie but she wouldn't answer to that," Cale said. "Riley, have you still got that tracker?"

"Yep." She pulled the tracker out of her back pocket.

"Were you guys not searched or something?" Jack asked. "'Cause I lost every electronic thing I own."

"We're just really good at hiding stuff," Riley said grinning.

"Cool, lets go then." They headed off in the direction that the Doctor had gone, Riley tracking him as they went.

It was some time later, and they had decided that wherever they were it wasn't just a police station. It looked more like the inside of an abandoned space ship. "Does anyone have a light?" Martha asked. "I can't see where I'm putting my feet." Valerie sighed.

"Okay Cat, try not to set fire to anything." The girl grinned and reached into her pocket. She pulled out an old silver cigarette lighter and flicked it on.

"Great," Lock said as they kept walking. "Now, not only are we lost in a strange ship full of people who don't like us, but Cat has a naked flame in her hands. There are so many ways this can go badly wrong."

"Have a little faith Lock," Riley said reprovingly. "We're not lost, and you never know, Cat might not set anything on fire this time."

"I feel like I'm missing something," Martha said.

"Cat's a pyromaniac," Jack said quietly. "She has a tendency to set things on fire."

"Hah!" Lock said, "A tendency? More like a compulsion."

"Children, children," Riley said, grinning. "Squabble later. We have other things to think about." She held up the tracker which was beeping. "We're close.
