The remnants of the base loomed above the squad. John stared for a moment, trying to figure out the best way to get inside, to say it wasn't structurally sound was the understatement of the century.

'Right, we go in groups of three. Don't touch anything unless you know it won't send what's left of the building crashing done on top of us.' He ordered. This time, he went with the two women. They decided to enter by the hole where they had exited at the time of the explosion. While the rest of the group looked for the equipment, they were looking for anything which could be used to show where Sherlock went.

The warehouse creaked and groaned with a slight breeze, keeping the group on edge, constantly looking up to see if the ceiling was about to fall in. After five minutes of searching around where John had fallen, looking at the way the stones had been set and where they could have come from, Jenny scampered across the ground, looking at the large doors with an odd expression.

'Captain.' She called quietly. John appeared beside her moments later. The female private point to the door.

'Everywhere else has got some damage but the door is completely fine.' She said. The doctor nodded and walked over to the doorframes.

'These were open when the explosion happened.' He stated, remembering that the lights had gone out and they hadn't got round to fixing them yet. He then realised that if they were still open when he got out, he would have been able to see enough to get out by himself. 'I'm guessing that once Private Holmes was taken, they closed the doors.' He said, running his fingers over the handle. His first instinct was to open it but something just didn't feel right. The captain looked up and around the doors.

'Shit.' He cursed. 'Get everyone out. Now. Go!' He yelled, switching the radio on and giving the order again before running to the exit himself. There was a shrill beeping sound which echoed off the jagged edges of the ruins.

John reached the entrance the squad had used to see that the two he went in with were both out along with nine others they had managed to find. The captain peered back into the warehouse, even with the dust and smoke settled, he found he couldn't see more than a metre and a half into the ruins. Picking up his radio, he relayed his orders again and felt the people behind him breath a sigh of relief as they saw movement. John himself wasn't about to let himself relax until he knew they were out. The shrill beeping was slowly becoming higher in pitch as it quickened. The remaining groups appeared, carrying large boxes between them and all but leapt out of the warehouse, sending the large metal boxes cascading in front of them. The shrill beeping stopped as soon as the last person stepped out. John's brow furrowed as he tried to work out what the hell was going on. The captain gestured for everyone else to stay back then he cautiously stepped back into the warehouse. As soon as his foot touched the floor, the beeping started up again. He stepped back out again and turned to his squad.

'Round the exit there's a mountain of wiring with what looks like a load of charges liked up to it. Not only that but the wires went up to the roof and God knows where else. Now this beeping might be part of that bomb or it could just be a ruse to scare us but I'm not going to take that chance. We've got what we came for and now we're going to get the hell out of here. Any questions?' He was met with silence. John nodded to himself and walked to the metal boxes. He inspected the outside carefully before unclipping the latch and lifting the lid.
