Dead Man's Grip

ran on, followed by a puffing Branson, stepping over metal slats and then past more red warning lights at the start of the curved walkway over the main lock gates. A sign cautioned against entering when the red lights were flashing and the siren was sounding.
    When he reached the join in the middle, between the two halves of the ancient, massive wooden lock gates, he turned and looked at
the power station again. What the hell was he doing up there, if it was the suspect? For sure it would be a terrific vantage point, but for what? Did he have the boy up there with him?
    They ran on, around the curve of the other half of the lock gates and on to the quay, then sprinted towards the power station. Ahead Grace saw a stack of pallets against the tall spikes of the power station’s perimeter fence.
    ‘Wait here,’ he said to Branson, then scrambled up the pallets.
    Having clambered over the top of the spikes, he dropped down ten feet or so to the other side. He landed with a painful jolt and allowed himself to fall forward, trying to roll to break his fall, but instead hit the ground chest first and lay there winded.
    Above, the helicopter clattered, the beam passing momentarily over him, illuminating the steel ladder up the side of the power station superstructure.
    He ran to it and began to clamber up, as fast as he could, the wind pulling at him as he climbed higher and higher. This is sodding crazy, he thought. But he climbed on, gripping each rung tightly, clinging to it, the rain lashing him while the wind pulled at him harder and harder, as if it was on a mission to dislodge him. Suddenly he heard a terrible, pitiful crying sound, like a woman in distress, and a huge black shape swooped out of the darkness at him.
    He turned his head instinctively and saw the lights of the harbour, and the city beyond, miles beneath him. The wind ripped at him even harder. The black creature was swooping, flapping, crying again. The peregrine falcons, he suddenly remembered, that were in a nesting box on the power station wall – some damned ecological deal that had been made when the place was built.
    The bird swooped again.
    Great! I’ve survived twenty years as a copper and now I’m going to be killed by a sodding protected bird.
    He clung to the rung, vertigo suddenly hitting him.
    Don’t let go. Hang on. Hang on. Remember rule one of ladders. Always keep three limbs on and you can’t fall off.
    With his fourth limb, his right arm, he swiped at the air, not
caring at this moment how much damage he did to a protected bird of prey. Then he climbed on, the wind stronger still.
    The bird seemed to have taken the hint and vanished back into the night.
    Finally, he was at the top. He hauled himself over, on to the asphalt roof, and crawled forward on his knees until he was safely away from the edge. He then stopped and crouched down, trying to get his breath back. His heart felt like it was about to explode as he looked around in the darkness. Moments later he heard the sound of the helicopter and the beam momentarily turned the entire roof, and the wall of the next stage of the superstructure, into daylight.
    Then he saw the camera.
    It was directly in front of him, on a squat metal tripod, the telephoto lens aimed down.
    He looked beyond it, for a brief instant, for the figure he had seen earlier, but there was no sign of the man. As the helicopter beam moved away, he ran to the camera, a complex-looking affair, found the viewfinder and squinted through it.
    Oh shit. Oh no. Oh no.
    In eerie green night vision, in a tight close-up, he could see Tyler Chase. The boy was suspended across the middle of the lock gates, several feet below the top, his feet inches above the surface of the water. His arms were outstretched, his hands strapped to the left and right gates. A tiny flashing light indicated the camera was running in recording or transmitting mode.
    And now to his horror he realized what that tide chart had been all about.
    He tried to raise Glenn on his radio but the channel was busy. Frustrated, he tried again. At the third attempt, with the helicopter right overhead, he heard his colleague’s voice.
    ‘Glenn!’ he shouted. ‘Stop the lock gates from opening! For Christ’s sake stop them! They’re going to kill the boy! They’re going to tear him in half!’
    The din of the helicopter and wind and the rain, which was now pelting down, was deafening.
    ‘Say that again?’ Branson said. ‘Can’t hear you,
