Miles was sat at his workstation working away, Jack was speaking in the coms, Louise and Ianto where on the move, he followed there tracking dots on the map they were just going up to the air conditioning vent, and old style system, easy to get in through, Jack had said people never check their air con-systems in buildings. Sam was nowhere to be seen he, he presumed she was feeding the weevils.

Sam walked around in the vaults, she opened the box the woman had given her the night before, she carefully removed the tiny dot of a camera and placed it next to the outer corner of her eye, close enough for them to be able to see what she could, she placed the small hearing device in her right ear, behind her Bluetooth. She had to stay in contact with both groups of people. They had to know what was going on.

"Welcome online Miss James. Don't worry, we can see everything." She smiled as the man on the other end of her coms started to tell her what to do.

"The vent is here." Ianto said. As they reached the edge of the building, Louise looked at it; Ianto took a screwdriver out of his pocket and started to unscrew the screws that were right around the edge of the frame. "You can't beat a good old fashioned screwdriver." Ianto muttered Louise turned to look at him, another one of his smiles on his face.

"Yeh you can!"

"Seriously?" Ianto looked unsure whether or not to believe her.

"You've never looked at a screwdriver and wished it was a little more sonic?"

"I don't understand." the Lieutenant laughed. Ianto just looked confused. She stepped away from the frame and Ianto saw she had already taken out the 10 screws securing the vent along the left hand side; he had managed 3 on the right. She moved over and pointed her screwdriver at it and Ianto watched in dismay as the screws turned and fell out.

"It makes putting up shelves so much easier!" Ianto held the grate as she undid the last two corner bolts; he carefully lifted it away from the wall.

"Ladies first." Ianto said as he stepped back placing the grate down, Louise shook her head.

"I need to put the grate back in place." Ianto sighed and climbed in, Louise placed two screws back in the top corners and climbed backwards into the vet, leaning down she lifted the aluminium grate and held it in place and re attached it. Ianto crouched quietly behind her. "Come on let's go." She said after she'd finished.

"We're looking for a vent going up in about 10metres." Ianto started to crawl along.

"How's it going?" Jack's voice crackled slightly over the coms.

"We're in the venting system." Louise whispered her voice would carry along the system, she hoped no one would hear.

"Right ok, well done, we'll drive by the vent and check it's still in place."

"Thanks but it should be good."

"Keep in contact."

"If we talk too much they'll hear we'll keep the link open ok?"

"Alright fine then." He sounded disgruntled. They carried on crawling down the vents.

"Here." Ianto stopped and looked up; he went a little further and turned around. To look at Louise, she looked up she knew he wanted her to go first, she looked up, it was just a metre up then back on the flat. Louise stood up in the tunnel her arms above her head.

"Use my shoulder as a step." Ianto whispered. She hated being a foot smaller than everyone else on the team, she carefully started to lift herself up and putting her foot on his shoulder she slivered up into the higher system. She looked around as Ianto's head and arms appeared, he easily lifted himself through.

Jack parked the SUV a block away from the building but they could see the main entrance, they watched as a large black car dropped several men off outside then drove off again, they all looked around furtively then went inside.

"That doesn't look like your average job, not if you have to look round like that before you go in!" Jack said looking at Gwen.

"They look just like us."

"What do you mean?"

"Whenever we get on that invisible lift we all look around like that, especially if there aren't many people around!"

"But we're working for good."

"But are we Jack?" Gwen looked at him. He didn't answer.

"There look." He pointed at the entrance as a woman walked up to it. She looked familiar.

"She shot you and Louise the other day, she's that unit woman." Jack looked at her, he tapped his coms and he could hear Louise and Ianto moving. He muttered quietly so not to startle them.

"You've got at least 6 heavies in there and that unit woman."

"Thanks Jack, we've just got out the ventilation."

"Thank god." Ianto muttered. Jack gave a sigh of a laugh; Ianto had never liked small spaces.

"Watch out, there could be more."

"Thanks Jack. Give us a heads up if you see more come in."
