‘Come back and talk to us. Please?' she said.

Helen had never heard that voice. She had often tried, staring intently up at her grandfather's face, watching his expression change, not daring to ask what it was he heard, but straining her own ears, desperate to catch an elusive echo. Like most men who had worked underground, Harry spent as much of his time as he could outside in the open air. As she stood at his side, Helen had learned to hear the sounds of the woods and the sky, the tiny movements in the grass, the shifting of the direction of the wind, the splash of a fish in a stream. But she had never heard what her grandfather heard. She had grown up to believe it was something uniquely to do with being a man.

‘If you don't want to talk to Grandma, won't you tell me about it, Granddad?’

And then the noise began to grow steadily louder again, clattering towards them as it followed the invisible line of the road that meandered along the valley bottom. It drew nearer and nearer across the rocky slopes of Raven's Side, skirting a sudden eruption of black basalt cliff and veering north once more towards the village until it was almost overhead. The din was enough to drown out normal speech. But it was then that Harry chose to speak, raising his voice defiantly against the clattering and roaring that beat down on him from the sky.

‘Noisy bastards,' he said.

The helicopter banked, its blue sides flickering in the fragmented shadows of its blades. A figure could be seen, leaning forward in the cabin to stare at the ground. The lettering on his door read 'POLICE'.

‘They're looking for that girl that's gone missing,' said Helen, her voice scattered and blown away by the roar. 'The Mount girl.’

Aye, well. Do they have to make so much row about it?’

Harry cleared his throat noisily, sucking the phlegm on to the top of his tongue. Then he pursed his thin lips and spat into a clump of yellow ragwort growing by the gate.

As if taking offence, the helicopter moved suddenly away from the edge of the village, sliding towards a row of tall conifers that grew in the grounds of a large white house. The pitch of the noise changed and altered shape as it passed the house, tracing the outline of the roofs and chimneys like an echo locator sounding the depths of an ocean trench.

At least it'll wake that lot up as well.'

‘Granddad —'

‘There's nowt more to be said. Not just now.’

Helen sighed, her brain crowding with thoughts she couldn't express and feelings she couldn't communicate. The old man only grimaced as his arm was stretched at an even sharper angle.

‘Have to go, love,' he said. 'Jess'll pull me arm off, Helen shook her head, but dropped her hand and let him go. A thin trickle of blood ran down her arm from the scratch made by the thorn. It glittered thickly on her pink skin, clotting and drying fast in the warm sun. She watched as her grandfather set off down the hillside towards the woods at the foot of the cliffs. Jess, his black Labrador, led the way along the familiar path, tugging eagerly at the end of her lead, impatient to be allowed to run free when they reached the stream.

No, you couldn't run away from things for ever, thought Helen. But you could always bugger off and walk the dog for a bit.

Down on the lower slopes of the hill, Ben Cooper was sweating. The perspiration ran in streams through the fine hairs on his chest and formed a sticky sheen on the muscles of his stomach. The sides and back of his T-shirt were already soaked, and his scalp prickled uncomfortably.

No breeze had yet found its way through the trees to cool the lingering heat of the afternoon sun. Each clearing was a little sun trap, funnelling the heat and raising the temperature on the ground into the eighties. Even a few feet into the woods the humidity was enough to make his whole body itch, and tiny black flies swarmed from under the trees in irritating clouds, attracted by the smell of his sweat.

Every man in the line was equipped with a wooden pole to sift through the long grass and push aside the dense swathes of bracken and brambles. The bruised foliage released a damp, green smell and Cooper's brown fell boots were stained dark to an inch above the soles. His pole came out of the undergrowth thick with burrs, and with small caterpillars and insects clinging to its length. Every few minutes he had to stop to knock them off against the ground or on the bole of a tree. All along the line were the sounds of men doing the same, the thumps and taps punctuating their muttered complaints and sporadic bursts of conversation.

Cooper found that walking with his head down made his neck ache after a while. So when the line stopped for a minute to allow someone in the centre the time to search a patch of dense bramble, he took the chance to raise his head and look up, above the line of the trees. He found himself gazing at the side of Win Low across the valley. Up there, on the bare, rocky outcrops they called the Witches, it would be so much cooler. There would be a fresh wind easing its way from the west, a wind that always seemed to come all the way from the Welsh mountains and across the Cheshire plain.

For the last two hours he had been wishing that he had used his common sense and brought a hat to keep the sun off his head. For once, he was jealous of his uniformed colleagues down the line, with their dark peaked caps pulled over their eyes and their starburst badges glittering in the sunlight. Being in CID had its disadvantages sometimes.

‘Bloody hell, what a waste of effort.’

The PC next to Ben Cooper was from Matlock section, a middle-aged rural beat manager who had once had aspirations to join the Operational Support Task Force in Chesterfield. But the Task Force were deployed further along the hillside, below the Mount itself, while PC Garnett found himself alongside an Edendale detective in a makeshift search group which included a couple of National Park Rangers. Garnett wore his blue overalls with more comfort than style, and he had been swinging his pole with such ferocity as he walked that his colleagues had gradually moved further away to protect their shins.

‘You reckon so?’

Aye, certain,' said Garnett. 'They say the lass has run off with some boyfriend.'

‘I don't know,' said Cooper. 'I've not heard that. It wasn't in the briefing. Just that she was missing.'

‘Huh. Missing my arse. Mark my words, she'll be off shagging some spotty youth somewhere. Fifteen years old, what do you expect these days?'

‘Maybe you're right. We have to go through the motions all the same.'

‘Mind you, if one of my two did it, I'd murder 'em all right.’

Garnett thrashed at a small elder sapling so hard that the stem snapped in two, the tender young branches collapsing to the ground and leaking a tiny trickle of sticky sap. Then he trod on the broken stem and crushed it into the grass with his police-issue boot. Cooper hoped that, if there were any fragile evidence to be found in the woods, he would see it before Garnett reached it.

Then he looked at the PC and smiled suddenly, recognizing that the man had no harm in him. He might be a middle-aged dad whose ambitions were withering as his waistline expanded, but he had no harm in him at all. Cooper could almost sense the ordinary little niggles that teemed in Garnett's mind, from his disappearing hairline to the recurring ache at the base of his spine and the size of his telephone bill.

‘Just be thankful for the overtime,' he said. 'We could all do with a bit of that.’

Ah yes, you're right there, lad. Too right. It takes something like this to get the fingers of those tight-fisted bastards off the purse strings these days, doesn't it?'

‘It's the budget cuts.'

‘Budgets!' Garnett said the word like a curse, and they both paused for a moment to listen to its sound, shaking their heads as if it symbolized the end of everything they had known.
