‘Stick with it, Hazel!’ he shouted. ‘Couple of minutes and this’ll be over.’
He didn’t know if that was true. What rate of progress were they actually making? Could they really cover two hundred yards in two minutes?
He tried to increase his speed, but a couple of times his feet slipped, shooting downward either left or right, leaving him dangling, lopsided. Though he never let go of the hand-rails, these were moments of the purest terror – yet thanks to the unseen presence behind, he always levered himself to his feet and pushed on with reckless speed.
Were they out in the middle of it yet? It seemed unlikely, but it was impossible to judge. When a yelp of horror came echoing back, Heck initially froze, but then stumbled forward as fast as he dared, the bridge swaying and tilting horribly. Two seconds later, he came up behind Hazel. Gemma was just in front of her, but she too had lost her footing, and was in the process of slowly, carefully raising herself up.
‘We can’t fart around,’ he said. ‘We’ve got to keep moving.’
Gemma threw him a baleful glance. It looked as if she was about to voice some very choice words, but then came a shuddering impact from their rear, a mighty THUNG resounding through the entire structure.
‘What was that?’ Hazel said, in a tone so querulous Heck barely recognised it.
‘Don’t bloody know,’ he muttered.
Another impact followed, and another. A horrendous realisation dawned on the two cops at the same time.
‘He’s trying to de-anchor us,’ Heck said. ‘Trying to tip us into the valley. Quickly, forward … forward!’
The women needed no second telling. Gemma lurched her way along at the front, the bridge swinging wildly.
‘He can’t cut through those cables, surely?’ Hazel said, breathless.
‘Let’s not wait to find out,’ Heck replied.
She turned to push herself on, only to shriek deafeningly as both feet slid off the cable-walk together. She dropped hard on her crotch and tilted to the right, legs pumping against nothing. For several seconds Heck thought she was going to pitch clean through and plummet into the chasm. He jerked his right arm down and grabbed her hood, though this meant he only had one hand in place himself. For several spine-freezing seconds they were locked together in the middle of nothing, wrestling to maintain their mutual balance, Heck’s left arm straining hideously under the combined weight. Slowly, barely breathing, he managed to haul her upright again.
All the time, shocks were passing through the bridge, repeatedly, getting increasingly heavy.
‘He can’t … can’t cut those cables,’ Hazel stuttered again, teeth chattering.
‘I don’t know whether he can or can’t,’ Heck replied. ‘But a lot of those pins were loose. How many does he have to knock out before gravity does the rest?’
‘Oh my God!’
‘Don’t think about it, just keep going!’
A deeper impact sounded behind them, followed by a squeeeaaal of splintering metal and then a reverberating whip-lash as the bridge lurched downward several feet. Hazel shrieked again. Twenty yards ahead, Gemma dropped to a crouch, arms rigid as she clutched the rails. She glanced back, white-faced.
‘Keep moving!’ Heck shouted. ‘It can’t be too far.’
‘We’re miles away,’ Hazel moaned, lunging desperately on.
Further thudding impacts shuddered past them.
Heck held his position, a crazy thought spinning. Slowly, he shuffled around and began to retrace his steps backward. It was several seconds before Hazel noticed.
‘Mark!’ she screeched. ‘What the hell are you doing?’
‘If he’s busy trying to de-anchor this thing, he might not be watching,’ Heck called back. ‘I might be able to get on top of him!’
‘Mark, for God’s sake!’
‘Just get moving … get to the other side!’ Heck pressed on back. The reality was they couldn’t have progressed more than a hundred yards. It seemed highly unlikely they’d make it to the other side if someone didn’t do something to distract the bastard.
‘Gemma, stop him!’ Hazel cried.
‘Heck!’ Gemma called.
‘Gemma, get Hazel to safety!’
‘Sergeant Heckenburg, get back here this fucking instant!’
‘Go!’ he shouted again, almost overbalancing as another thunderous blow struck the bridge. The flimsy structure lurched to the left, and he had to clamp the cable on the right with both hands. A fog-filled chasm yawned directly beneath him.
What in the name of God was he doing?
It only struck Heck now that if the bridge collapsed while he was near the broken end of it, he’d have far less chance of surviving. Even clinging on, he’d have a much longer distance to travel.
‘Okay … okay!’ he said, forcibly getting hold of himself, suddenly baffled that he could ever have thought this was anything more than the stupidest idea in history.
He might die going the other way, but he’d certainly die going this way.
Fingers locked painfully into rusted steel, he pivoted back around, and began struggling forward again. All around him metalwork shuddered, one massive vibration following another as the suspension cables were assailed.
‘How you guys doing?’ he shouted, no longer able to see the two women.
This time there was no reply, but there was so much noise from the bridge that any responses were likely lost. He advanced with rash speed, leaning precariously to the right but not letting that worry him as he took longer and longer strides. It was still impossible to judge how much distance he was covering; there were no points of reference. With a reverberating CLUNG, the bridge sagged again, tilting even further to the right. Muffled shrieks tore through the fog. Yet the women had to be almost at the other side by now. It might have been Heck’s imagination, but the footway appeared to be sloping upward, as though he’d passed the dip at its centre.
‘Heck, where are you?’ someone called back. It was Gemma. Relief was palpable in her voice. ‘We’ve made …’
‘I’m almost there,’ he shouted, gravity tugging on him as he sidled along, corroded metal burning through his gloves, digging into the muscle and bones of his fingers. The bridge was definitely angling upward now. ‘Couple of min—’
It fell away beneath him.
Heck didn’t even hear the fatal blow.
All he knew was that another sharp vibration rocked the structure and that it flipped all the way to the right, before collapsing in a chaos of whining, whipping wires and cables. Heck’s body plummeted through mid-air, but by sheer instinct his left hand remained wrapped around the cable – and half a second later he wasn’t dropping like a stone so much as swinging like a pendulum.
The Via Ferrata had held its mooring on the far side.
One breathless second later, a granite wall hung with tufts of vegetation came hurtling towards him out of the fog. Heck gazed at it, goggle-eyed, knowing that any such impact would break him to pieces. But all the time he was losing altitude, and now he dropped below the level of the rock-face, heading instead for a steep, bracken-clad embankment. The next thing, he was crashing through layers of dead vegetation with pile-driving force. As well as knocking every
