There was a small but regular fluctuation in monolattice filament output, starting nine months ago. A three per cent shortfall every month, and always in one batch. According to production records the filament extrusion ratio was incorrect, each time.

Julia cross-referenced it with the memox data. It fitted like a jigsaw. Whenever the monolattice filament output dipped, the memox crystal output rose to compensate, maintaining total production losses at a level thirteen point two per cent.

She'd found it. Though what the hell it was, she hadn't got a clue.

End HighSteal#Two. Her processor nodes sucked the data mirage back into nothingness. There was a brief impression of free fall, dropping back into the world of primary sensations. The clammy late-March heat, blouse sticking to her back, tight sweaty Levis, smell of horse breath, birds trilling, red pressure on her eyelids.

Julia blinked, focusing slowly. A cloud of midges were orbiting the brim of her tatty boater.

She was in what she called the crater field. Two acres of small steep-sided hummocks and hollows, like the earth had been bombed or something. Buttercups smothered the rich emerald-coloured grass all across the slopes.

A twitch on Tobias's reins, and he plodded towards the derelict tea plantation.

The communal farmers had tried to grow it on a PSP grant. Tea was fetching a good price after the Sri Lankan famine reduced the global harvest by a third, and England's new climate provided near-ideal conditions for cultivation. But these were gene-tailored trees, and some nameless State lab had screwed up the DNA modification. The shoots were fast-growing all right, but the leaves ruptured into bulbous cherry blisters before they were ripe enough for picking. The plantation had gone the way of most PSP initiatives, abandoned and left to rot.

Julia dismounted, letting Tobias nuzzle round in the clover. The shire horse was becoming unfortunately flatulent in his old age. Poor dear.

He was another legacy of the communal farm, too old for plough work any more. The labourers had left him behind for Philip Evans to knacker, a trifling expense for a multibillionaire.

Julia had found him alone in the stables as she explored Wilholm the day they moved in. She'd fallen for the great shaggy animal at first sight. He was woefully thin, his coat caked in mud, covered in sores from the plough harness. And he'd looked at her so mournfully, as if he knew what the future held. That had been the last time anyone at Wilholm, including Grandpa, had dared to mention the knackers. She refused to ride anything else, and ignored the snickers and winks of the staff when they saw her on the back of the huge plodding beast.

"You'll have to lose that sentiment of yours, girl," Philip Evans had scolded. "Can't run Event Horizon on sentiment."

Except she knew damn well he would have done the same thing.
