It was less than half an hour before Donna heard the steady thwump thwump thwump of a helicopter coming in to land. She had no idea where they were going to land in the middle of Kingston but she hoped that it was Martha and UNIT. A few minutes later Martha came running down from the car park. There was a whole UNIT of people and they seemed to know what they were doing. The cordoned off the passage from the Bentall Centre into the actual car park and then they started to take scans of the air around the area where Donna said that the teleport had been. They took swabs of the floor and of the air.

"Are you okay?" Martha asked Donna. She could see she was shaken and upset and worried.

"I shouldn't have left him. I shouldn't have made him come. He hates shopping and…"

"This is not your fault," Martha advised Donna. "If someone was after him then they would have got hold of him no matter where you were."

"They were after him," Donna commented. "I heard one of them say that their mission had been a success and they had him?"

"Hopefully they want something off him then and they aren't just going to kill him outright," Martha offered trying to be pragmatic, but clearly putting another horror into Donna's mind. Would someone just want to kill him? There were species who would just want to kill him weren't there? Even if they didn't want to kill him what if they were running a mission for someone who did want to kill him.

"Anything?" Martha asked one of the soldiers who was scanning the area.

"We are picking up an energy trace, Ma'am," he confirmed. "There is a high level of ionisation in this area. It is dissipating, but it would suggest a high energy transfer took place. It's nothing that we are intimately familiar with, Ma'am, but something happened here."

"Something did happen here!" Donna yelled. "The Doctor was kidnapped here!"

"Yes ma'am," the soldier confirmed and nodded.

"We will find him," Martha assured Donna. "Package the data and send it through to this number," Martha instructed and shared a number with the soldier from her phone. She then picked it up and dialled the same number.

"Voice of a nightingale?" Jack commented. "How are you doing?"

"We've got a situation, Jack," Martha told him not wasting time.

"Oh? What kind of a situation?"

"It appears that the Doctor has been kidnapped."

"What?!" Jack exclaimed horrified by the idea. "Where from? What planet is he on?"

"From Earth, Jack. He was taken right from under our noses. He was shopping with Donna in Kingston and she saw him get taken."

"Donna, she is his latest companion isn't she? I've not met her yet. What happened?"

"She says that she sent him to get a cup of tea because he was bored with shopping."

"I can't imagine that took long," Jack commented.

"No, I don't think it did. He went to get a cup of tea but when she went to catch up with him in the café he wasn't there. She said that she was directed by another girl to where she had seen the Doctor go. He was down by the car parking pay metres and that there were three large individuals around him. She said that he got hit twice and he got knocked out and then they seemed to use some kind of energy transfer system such as a teleport to take him."

"Okay, a teleport of some kind?" Jack stated thoughtfully. "Have you got the facility to scan the energy traces?" he asked. "Do a scan and send the details through. Maybe we can trace the source or the destination or at least the type of device used."

"Already done, Captain," Martha advised him. "The scanned data is on its way to you. It is not coming up with a hit from UNIT so it's not a device regularly used on Earth. We need to find him and we need to get him back."

"Are we sure he wasn't just really bored with the shopping?" Jack asked. Martha couldn't help a slight chuckle at that, but she knew how worried Donna was.

"He got hit," Martha reminded Jack. "He could be hurt."

"I will get on the trace."

Jack had been down in his basement office when his phone rang. There was some energy data showing on his desktop and he went up to the main area. "Gwen! Ianto! We've got work to do," Jack advised them. They came over from what they had been doing. Thankfully the rift had been quiet for a few days so they weren't being dragged away from anything too important. "We have an energy signal we need to trace," Jack advised. "We need origin if possible and we also need source and destination. Hopefully they are one and the same."

"Where is the data?" Ianto asked.

"I've had it sent through," Jack commented. "It's on the desktop. Let me just pull it out. I may recognise the signature?" he offered. He had intimate knowledge of many teleports. The most familiar to him would be recognisable based on the signature of the feed providing the data was taken early. Time was ticking away from them fast especially with the Doctor kidnapped. It was going to be hard to focus and to concentrate on doing the work they needed to find him as Jack was already worrying about all the different things they could be doing to him. There was no point him wondering who would want to harm or to take the Doctor, there were hundreds of species and individuals who could benefit from either having a Time Lord or having the Doctor or would maximise the potential by acknowledging they had both.

Jack looked at the data as it came up. The energy field had a high level ionisation trace. That was good. It meant it was a low power teleport but it also meant that they weren't cloaking their technologies. Either they didn't have the technology themselves to do that, or, they didn't think contemporary humans would have the technology to conduct a trace. They shouldn't have the technology to conduct a trace, but Torchwood did. He didn't recognise the actual signature itself, it seemed to have a strontium gate. That would have given it a reddish tone as the energy ionised. Red teleports were very rare. They were cheap to run but they didn't have a very large range. That was good. He didn't think the Doctor could have been transported anywhere off planet. They may have made it to a ship in low orbit, but no further than that.

"Martha, you still there?" Jack checked as he had kept the line to her open.

"I'm here," Martha confirmed.

"Have UNIT been tracing any incursions into orbit?"

"I will check," Martha offered.

"They can't have taken him further than a low orbit with a strontium gate teleport. Can you check with Donna that the teleport had a red hue to the energy?" Jack asked her.

"I will." Martha turned to Donna. She had moved to squat down to sit on the low barrier running around the base of the foyer. There was nothing else she could do. "Donna? Jack is trying to identify the type of teleport used. He is asking if the energy was red."

"Yeah," Donna confirmed. "Some of it was. It came down over them and it was sparking in white and yellow, then it was red when it swirled around them, and then as it raised up again and they were gone it went back to white and yellow," she explained.

"Did you hear that Jack?" Martha checked.

"Loud and clear, thank you," Jack confirmed. "It's definitely a strontium gate teleport. Quite a standard one according to that," he offered. "What did the people that took him look like? Did they have any markings or were they wearing any kind of uniform? Did they have any tools on them? Anything that can be used to try and identify them?"

"They were big but they generally looked human," Martha confirmed and Donna nodded her agreement. "What about colouring Donna, did they have the same colour hair or anything?"

"They all had black hair, it was very dark and it was coarse and wavy. Their skin was very white though, it was almost kind of a green colour in places too as if they looked sick. I don't know what that was," Donna offered. "They were big a strong though and they were all wearing black tunics and sandy coloured trousers," she advised. "I don't know if that is a uniform or fashion."

"Were there any emblems on it?"

"Not that I saw. One of them had a scanner. He was the one who said that their mission had been a success, and he was the one who talked into his watch thing and got the teleport to work," Donna advised remembering more details. "It was the littler one that hit him and he used a device that looked like a club. It was bright silver in colour and it was short and it had a handle and a thicker end. He was hit with it twice," Donna offered. "He went down so hard."

"We will find him and make sure that he is alright," Martha told Donna though she had her own fears. If he had received a severe blow to the head as it sounded then they needed to get to him as quickly as possible in case there was any damage to be dealt with.

"Jack?" Gwen got his attention as she worked on the computer with Ianto to try to find out where the energy trace had come from. "I think we have it," she commented. "The source of the energy? There was an energy surge with the same traces of strontium."

"When?"

"Forty two minutes ago," Ianto advised. "Does that coincide with the Doctor's abduction?"

"I think so," Jack confirmed. "Martha, have you not got any CCTV in that area?"

"I've got a unit team pulling that now so we can look at it," Martha confirmed. "I've had an initial report that says that the CCTV actually in this area has been malfunctioning, but we are pulling all the store footage to see if we can locate the people responsible on the feed. That may help us identify the species and then the source?"

"I hope so," Jack agreed. "Gwen, where are you picking the signal up?"

"About seventy five miles off the Northern Coast of Alaska," Gwen advised.

"At sea?"

"Yes, within the Arctic Circle," Ianto confirmed on her behalf. "There must be a ship out there. I am going to attempt to access all shipping lane data in that region," he offered and Jack nodded. "It doesn't correspond with a known island."

"See what satellite footage we can get out there as well," Jack confirmed. "Martha?" he used the link through to there as well. "We think there may be some kind of ship out by Alaska where the signal has come from."

"It's not a usual shipping lane. There are no cargo ships using that line," Ianto offered.

"It will be quiet then," Gwen offered. "Easy to hide?"

"Easier to hide if we're not looking, easier to locate if we are," Jack advised. "Get a fix on any vessel out in that region. Scan them for any unusual energy signatures or strontium deposits and scan them for anything else that can be associated with extra-terrestrial activities. The usual, all frequencies, please." Jack knew that his team could look for alien activities and if there were aliens using alien technology on an alien on a ship in the middle of the ocean then they would be able to find it.

"Jack, if he is all the way out there how long is it going to take us to get to him?" Martha asked.

"You need to find out what resources UNIT are going to make available," Jack advised. "We don't want to have to rely on commercial airlines to get over there. That will take too long."

"Find him," Martha offered. "I will get us what we need." She turned to Donna who was feeling pretty useless as she couldn't do anything to find him. "It looks like the teleport at was activated from a ship that is off the coast of Alaska," Martha told her. "Jack is going to confirm that and then we will do whatever it takes to get out there and get him back."

"What do you need me to do?" Donna asked her.

"We need to think about seeing what the TARDIS can do to help and to secure her," Martha advised Donna and she nodded. "Can we get over there and see what she can do? Maybe she will be able to tell us where the Doctor is and who it is who took him. Where is the TARDIS?"

"It's all the way over at the back of the train station," Donna complained.

"That is okay, we will have some ground crew here by now," she offered. She got onto her radio and ordered a jeep up into the car park to pick them up. Donna and Martha got in it and they headed over to the TARDIS. All the time Martha and Jack maintained contact to ensure that they were keeping each other up to date.
