Stormbreaker

slow down. He knew he mustn’t panic. He forced himself to think. If you panic, you’ll get lost. Think what you’re doing. Be careful. One step at a time…
    “Okay. Okay…” He whispered the words to reassure himself, then continued forward.
    Now he emerged into a sort of wide circular chamber, formed by the meeting of six different tunnels, all coming together in a star shape. The widest of these slanted in from the left with the remains of a railway track. He swung the flashlight and saw a couple of wooden wagons that must have been used to carry equipment down or tin back up to the surface. Checking the map, he was tempted to follow the railway, which seemed to offer a shortcut across the route that Ian Rider had drawn. But he decided against it. The map told him to turn the corner and go back on himself. There had to be a reason. Alex made another two chalk crosses, one for the tunnel he had left, another for the one he was entering. He went on.
    This new tunnel quickly became lower and narrower until Alex couldn’t walk unless he crouched. The floor was very wet here, with pools of water rising up to his ankles. He remembered how near he was to the sea and that brought another unpleasant thought. What time was high tide? And when the water rose, what would happen inside the mine? Alex suddenly had a vision of himself trapped in blackness with water rising up to his chest, his neck, over his face. He stopped and forced himself to think of something else. Down here, on his own, far beneath the surface of the earth, he couldn’t make an enemy of his imagination.
    The tunnel curved then joined a second railway line, this one bent and broken, covered here and there in rubble, which must have fallen from above. But the metallic tracks made it easier to move forward, picking up the reflection of the flashlight. Alex followed them all the way to a junction with the main railway. It had taken him thirty minutes and he was almost back where he had started, but shining the flashlight around him, he saw why Ian Rider had sent him the long way around. The shorter route had been blocked by a tunnel collapse. About thirty yards up the line, the main railway came to a dead end.
    He crossed the track, still following the map, and stopped. He looked at the paper, then again at the way ahead. It was impossible. And yet there was no mistake.
    He had come to a small, round tunnel dipping steeply down. But after a brief stretch, the tunnel simply stopped with what looked like a sheet of metal barring the way. Alex picked up a stone and threw it. There was a splash. Now he understood. The tunnel was completely submerged in water as black as ink. The water had risen up to the ceiling of the tunnel, so even assuming he could swim in temperatures that must be close to freezing, he would be unable to breathe. After all his hard work, after all the time he had spent underground, there was no way forward.
    Alex turned in frustration. He was about to leave, but even as he swung the flashlight around, the beam picked up something lying in a heap on the ground. He went over to it and leaned down. It was a diver’s dry suit and it looked brand-new. Alex walked back to the water’s edge and examined it with the flashlight.
    This time he saw something else. A rope had been tied to a rock. It slanted diagonally into the water and disappeared. Alex knew what it meant.
    Ian Rider had swum through the submerged tunnel. He had worn a dry suit and he had managed to fix a rope to guide him through. Obviously he had planned to come back. That was why he had left the dry suit there. And why he had left the padlock open.
    Alex picked up the dry suit. It was too big for him, although it would probably keep out the worst of the chill.
    But the cold wasn’t the only problem. The tunnel might run for ten yards. It might run for a hundred. How could he be sure that Ian hadn’t used scuba equipment to swim through? If Alex went down there, into the water, and ran out of breath halfway, he would drown. Again his imagination got the better of him. He could see himself, pinned underneath the rock in the freezing blackness. He couldn’t imagine a worse way to die.
    He stood for a moment, holding the suit in his hands. Suddenly everything seemed unfair. He had never asked to be here. He had been forced into this by M16 and he’d already done more than enough. There was nothing on earth that would make him enter the blackness of the water. It was
