After he’d managed to get things set up in the bunker just as he wanted, and begun formulating the detail of his plan, he had found physical activity a welcome distraction, so had often spent time clearing rubble out of the escape tunnel. At the end of the tunnel he found only bare earth, checked the position of that point on GPS, then dug towards a particular location, sealing the earth walls all along the way behind him with a spray of fibre bonding. His tunnel exited about a hundred metres away from the bunker, through the side of a drainage dyke, and just another few metres from a wide underground pipe.
As Hannah went ahead of him, down the stairs to the lower floor, he felt really reluctant to leave. So much work, so much equipment – and a home of his own. He would have had to abandon it at some point, but hadn’t expected it so early in the game. Saul stepped over to one of the computer consoles to input the code detaching the whole system from the surrounding agricultural network, then input another code, whereupon a number of things happened simultaneously. A proximity explosive activated under the entrance hatch, the computer began scrubbing data and overwriting with nonsense, time and time again, and a three-minute countdown began to trigger detonators within the Hyex laminate buried in the bunker walls, and along the walls of the tunnel below. He took one last regretful look around, then followed Hannah downstairs.
A steel door closed off the entrance to the tunnel. He now unlocked and opened it, pointing his assault rifle inside, just in case the cam images he had seen from down here had in some way been subverted. Nobody home, thankfully, but then they wouldn’t have had time to do seismic scanning here, so hopefully only knew that he’d descended into a hole in the ground. He moved ahead, rifle braced against his shoulder constantly and his nerves on edge. Fragmented memories surfaced of what happened to him the last time the Inspectorate had got him in its tender care, so the weight of the grenades in his pockets was a comforting one. Whether they took Hannah alive, he left up to her, but they certainly would not be capturing him.
The tunnel curved round, lined with concrete until they entered the freshly dug section, where the walls now looked to be made of fibreglass. He then caught a whiff of something: a perfume-like smell that was characteristic of some insecticides.
‘Gas! Run!’
As they hurtled ahead, he could feel the knockout gas starting to haze everything. Soon they reached the exit hatch, where he fought a growing lethargy whilst undogging it. He thrust it open and hauled himself out on to a muddy slope, then had to reach back inside and drag out Hannah, who seemed unable to control her limbs. He slammed the hatch shut.
