A big thank you to Persiflage for beta-reading.

Chapter 3

The Torchwood team, the Doctor and Martha got out of the car near an abandoned warehouse just outside the city. The energy signature scanner had found a creature inside the warehouse. They had already tried to catch two other creatures in the last couple of hours but before they had been able to get even close to the buildings the creatures had changed their position.

"Gwen, Ianto, go to the back of the building and wait by the door. Take the force field device with you. We'll try to make the creature move in your direction and then you can catch it when it tries to flee."

He got two nods from Gwen and Ianto before his two team-mates left to get to the other side to of the building. The Doctor, Martha and Jack waited a few moments to give them time to get into position.

"Why do you think the creature will try to leave through the back entrance," Martha asked. "We don't have the device or anything else the creature would be afraid of."

"The creatures always flee when there's more than one person near them. They only kill when their victim is alone. I hope it won't see Gwen and Ianto and will fly directly into our trap," Jack explained. "Just trust me. We've done this before."

Gwen and Ianto were now out of their sight on the other side of the building. Jack waited a few seconds longer before walking towards the main entrance of the building. The Doctor and Martha followed him.

"The Doctor and I should go back to the Hub after this," Martha said. "We'll need to find a way to talk to these creatures."

The Doctor nodded. "Maybe I can communicate with them telepathically. Most energy or gas based creatures communicate like that."

"Why would you want to talk to them? They are obviously hostile," Jack said.

"Maybe we can convince them of a peaceful solution," Martha said. They were now standing in front of the entrance. "We don't know why they are doing what they are doing."

"We don't even know if they are intelligent. But it might be worth a try," Jack said, though he didn't seem to be convinced that their plan was anything more than a waste of time.

"The creature will move away from us. Stay within ten meters from each other and make sure the creature can't get past you," Jack advised before he opened the door. They all slipped inside the warehouse and the Doctor pulled the door closed behind him.

Inside the warehouse was a creature that looked exactly like the one they had seen in the glass cube inside Torchwood Hub. It was hovering in the air in the middle of the hall, unmoving, as if it had been waiting for them. The Doctor slowly walked closer with his sonic screwdriver in his hand, pointing it at the creature. Martha and Jack followed him. When they drew closer to the creature it slowly hovered higher into the air.

"It's not exactly fleeing from us," the Doctor commented while looking at Jack with a raised eyebrow.

Jack walked past the Doctor until he stood directly under the creature. "It's not moving. Maybe it's injured or something,"

In that moment, when Jack looked towards the Doctor and Martha and away from the creature, it started to move fast. It flew directly towards Jack. The Doctor quickly reached out and gripped Jack's arm to pull him away, but the creature only flew past them with incredible speed and stopped near the entrance they'd come though, hovering in mid air again just like before.

"This one's not behaving like the others," Jack commented.

Martha walked towards the creature and it shot past her to hover behind her in the air. It stayed as far away from the other side of the hall as possible. She tried again to get near the creature, but it reacted in the same way as before. "It's like it's playing with us," Martha murmured. Then she turned back to the two men. "Maybe it knows what we are trying to do."

Jack walked towards the creature again, but it only moved past him like before. "Okay, let's try this differently." He activated his headset. "Gwen, Ianto, come inside now."

The two Torchwood team members opened the door on the other side of the hall and closed it behind them before running towards their friends.

"What's going on," Gwen asked.

"The creature keeps moving past us, but keeps its position when we don't move. We'll have to try and catch it in here."

...

They made a few tries to circle the creature in and catch it with the force field generator, but the creature always got away. It moved too fast for them to get even close to it now. They soon had to accept that they were not going to catch any more creatures this way, at least not this one.

"We need a new plan," Gwen said.

"We still have the creature in the Hub," Jack said. "The Doctor wanted to try to communicate with it. And we might think of something else."

"Hopefully before anyone else dies," Ianto commented.

"Can't you try to talk with this one?" Gwen asked the Doctor.

"It won't be able to use or understand verbal language," the Doctor explained. "I might be able to talk to it telepathically, but I need to be near the creature. It will be much easier with the caged one in the Hub."

As they left the warehouse, the creature was again hovering in the middle of the room like it had been when they'd arrived.

...

A short time later, the Torchwood team plus the Doctor and Martha entered the tourist information office that housed the secret entrance to the Torchwood Hub. The moment they went inside they noticed that something was wrong; the door that looked like a wall which led to the Hub was open.

"I thought no one but us could open that door," Jack said, pulling out his gun.

"I thought so, too," Ianto replied. They carefully walked towards the door.

"No guns, Jack," the Doctor said. He walked past them while pulling out his sonic screwdriver to scan the door. After a quick scan he pocketed it again and walked into the Hub.

They soon noticed that the computer system was offline. All the doors that led to the main room were open.

"Who could have done this?" Gwen asked.

"I have a feeling I know who it might have been," the Doctor replied. He ran towards the infirmary and stopped to look at pieces of glass that were scattered all over the floor.

"What is this?" asked Martha, who'd followed him into the infirmary.

"The glass cube," the Doctor explained. "The creature is gone."
