Still, it had to be done.

And the day had begun well. The tractor was healthier after its overhaul, and the morning sky was rife with gulls, across from the coast for a meal of freshly turned worms. They'd kept him raucous company as he worked, their insolence and their short tempers always entertaining. But then, when he came back to the field after a liquid lunch in "The Tall Man, things began to go wrong. The engine started to cut out for one, the same problem that he'd just spent Ј200 having seen to; and then, when he'd only been back at work a few minutes, he'd found the stone.

It was an unspectacular lump of stuff: poking out of the soil perhaps a foot, its visible diameter a few inches short of a yard, its surface smooth and bare. No lichen even; just a few grooves in its face that might have once been words. A love-letter perhaps, a 'Kilroy was here' more likely, a date and a name likeliest of all. Whatever it had once been, monument or milestone, it was in the way now. He'd have to dig it up, or next year he'd lose a good three yards of ploughable land. There was no way a plough could skirt around a boulder that size.

Thomas was surprised that the damn thing had been left in the field for so long without anyone bothering to remove it. But then it was a long spell since the Three Acre Field had been planted: certainly not in his thirty-six years. And maybe, now he came to think of it, not in his father's lifetime either. For some reason (if he'd ever known the reason he'd forgotten it) this stretch of Garrow land had been left fallow for a good many seasons, maybe even for generations. In fact there was a suspicion tickling the back of his skull that someone, probably his father, had said no crop would ever grow in that particular spot. But that was plain nonsense. If anything plant life, albeit nettles and convolvulus, grew thicker and ranker in this forsaken three acres than in any other plot in the district. So there was no reason on earth why hops shouldn't flourish here. Maybe even an orchard: though that took more patience and love than Thomas suspected he possessed. Whatever he chose to plant, it would surely spring up from such rich ground with a rare enthusiasm, and he'd have reclaimed three acres of good land to bolster his shaky finances.

If he could just dig out that bloody stone.

He'd half thought of hiring in one of the earth movers from the building site at the North End of the village, just to haul itself across here and get its mechanical jaws working on the problem. Have the stone out and away in two seconds flat. But his pride resisted the idea of running for help at the first sign of a blister. The job was too small anyhow. He'd dig it out himself, the way his father would have done. That's what he'd decided. Now, two and a half hours later, he was regretting his haste.

The ripening warmth of the afternoon had soured in that time, and the air, without much of a breeze to stir it around, had become stifling. Over from the Downs came a stuttering roll of thunder, and Thomas could feel the static crawling at the nape of his neck, making the short hairs there stand up. The sky above the field was empty now: the gulls, too fickle to hang around once the fun was over, had taken some salt-smelling thermal.

Even the earth, that had given up a sweet-sharp flavour as the blades turned it that morning, now smelt joyless; and as he dug the black soil out from around the stone his mind returned helplessly to the putrefaction that made it so very rich. His thoughts circled vacuously on the countless little deaths on every spadeful of soil he dug. This wasn't the way he was used to thinking, and the morbidity of it distressed him. He stopped for a moment, leaning on his spade, and regretting the fourth pint of Guinness he'd downed at lunch. That was normally a harmless enough ration, but today it swilled around in his belly, he could hear it, as dark as the soil on his spade, working up a scum of stomach-acid and half-digested food.

Think of something else, he told himself, or you'll get to puking. To take his mind off his belly, he looked at the field. It was nothing out of the ordinary; just a rough square of land bounded by an untrimmed hawthorn hedge. One or two dead animals lying in the shadow of the hawthorn: a starling; something else, too far gone to be recognisable. There was a sense of absence, but that wasn't so unusual. It would soon be autumn, and the summer had been too long, too hot for comfort.

Looking up higher than the hedge he watched the mongol-headed cloud discharge a flicker of lightning to the hills. What had been the brightness of the afternoon was now pressed into a thin line of blue at the horizon. Rain soon, he thought, and the thought was welcome. Cool rain; perhaps a downpour like the previous day. Maybe this time it would clear the air good and proper.

Thomas stared back down at the unyielding stone, and struck it with his spade. A tiny arc of white flame flew off. He cursed, loudly and inventively: the stone, himself, the field. The stone just sat there in the moat he'd dug around it, defying him. He'd almost run out of options: the earth around the thing had been dug out two feet down; he'd hammered stakes under it, chained it and then got the tractor going to haul it out. No joy. Obviously he'd have to dig the moat deeper, drive the stakes further down. He wasn't going to let the damn thing beat him.

Grunting his determination he set to digging again. A fleck of rain hit the back of his hand, but he scarcely noticed it. He knew by experience that labour like this took singularity of purpose: head down, ignore all distractions. He made his mind blank. There was just the earth, the spade, the stone and his body.

Push down, scoop up. Push down, scoop up, a hypnotic rhythm of effort. The trance was so total he wasn't sure how long he worked before the stone began to shift.

The movement woke him. He stood upright, his vertebrae clicking, not quite certain that the shift was anything more than a twitch in his eye. Putting his heel against the stone, he pushed. Yes, it rocked in its grave. He was too drained to smile, but he felt victory close. He had the bugger.

The rain was starting to come on heavier now, and it felt fine on his face. He drove a couple more stakes in around the stone to unseat it a little further: he was going to get the better of the thing. You'll see, he said, you'll see. The third stake went deeper than the first two, and it seemed to puncture a bubble of gas beneath the stone, a yellowish cloud smelling so foul he stepped away from the hole to snatch a breath of purer air. There was none to be had. All he could do was hawk up a wad of phlegm to clear his throat and lungs. Whatever was under the stone, and there was something animal in the stench, it was very rotten.

He forced himself back down to the work, taking gasps of the air into his mouth, not through his nostrils. His head felt tight, as though his brain was swelling and straining against the dome of his skull, pushing to be let out.

'Fuck you,' he said and beat another stake under the stone. His back felt as though it was about to break. On his right hand a blister had bust. A cleg sat on his arm and feasted itself, unswatted.

'Do it. Do it. Do it.' He beat the last stake in without knowing he was doing it. And then, the stone began to roll.

He wasn't even touching it. The stone was being pushed out of its seating from beneath. He reached for his spade, which was still wedged beneath the stone. He suddenly felt possessive of it; it was his, a part of him, and he didn't want it near the hole. Not now; not with the stone rocking like it had a geyser under it about to blow. Not with the air yellow, and his brain swelling up like a marrow in August. He pulled hard on his spade: it wouldn't come. He cursed it, and took two hands to the job, keeping at arm's length from the hole as he hauled, the increasing motion of the stone slinging up showers of soil, lice, and pebbles.
