my computer. And they get to pick their grapes at the moment of perfection. It’s not a judgment call; it’s science.
‘And, you know, it doesn’t stop there. Once it’s in the barrel, I run tests at regular intervals. Wines are hard to taste in the early days, but I can measure the key compounds, and can make a quality judgment from the facts and figures in my database. We can then make virtual blends between barrels and run the figures through the computer to see how they’ll taste. That way, you don’t actually have to mix the wine until you know it’s going to be good.’
He laughed. ‘I had dinner with a client the other week. He produced a bottle of his best wine. I told him I would be really interested to taste it. I’d only ever tried it on my computer screen.’ He leaned confidentially across his desk. ‘These wine critics… Petty, Parker and the rest. They’re so goddamned predictable. I say to them, this is what you like? Okay this is what I’ll make. In a blind tasting I’ll predict nine times out of ten the score they’re going to give. And do you know what kind of power that gives me, Magpie? It’s like knowing today what a stock’ll do tomorrow. It’s inside info.’
And Enzo thought of the lengths that Petty had gone to just to keep his ratings secret. Of the alchemy that Laurent de Bonneval had talked about at Chateau Saint-Michel when Enzo first arrived in Gaillac. MacConchie was exploding it all. The myths, the mysticism, and two thousand years of tradition. His secret for success was a marriage of Silicon and Napa Valleys; his wines constructed from the building blocks of molecules. And Enzo couldn’t help but wonder if in all this science, the fundamental human component might be missing. The instinct, flair, and sophistry of which Bonneval had spoken. That element impossible to define by maths or science-the personality of the winemaker.
But he said none of this to MacConchie. There was no point. Whatever it was he was doing, it was working for him. A hundred clients on his books and a turnover of five million a year. A lifestyle that a boy from a housing scheme in Glasgow’s deprived east-end could hardly have dared to dream of. He’d had a brain, and used it. Enzo regarded him thoughtfully across the desk, and couldn’t help but admire him. They’d both come a long way in the thirty years since they’d first met. And very different paths had led them, strangely, to meet again in this place in the heart of California wine country, thousands of miles and millions of dollars away from where they had started.
‘You know, if Petty hadn’t been murdered, he was going to publish an article urging a boycott of American wines.’
MacConchie looked at him in disbelief. ‘What?’
‘Unlabelled use of genetically modified yeasts. He thought it was unethical. And dangerous.’
‘Jesus, Magpie. If he’d published that he could have put us all out of business!’
Enzo cocked his head. ‘Which reduces my list of suspects to a mere few thousand.’ He paused. ‘So how will you treat the samples?’
MacConchie leaned forward, concentrated on the question. ‘I figure I’ll dry the soil samples in an oven up to a constant weight. Sieve the stuff through nylon nets to fraction and homogenise it, then digest it with concentrated HN0^3 by high pressure microwave.’
Enzo looked at him. ‘Can you translate any of that into English?’
MacConchie grinned. ‘Chemistry never was your strong suit, Magpie, was it?’ He stroked his chin thoughtfully. ‘You know, it’s not easy to explain this in layman’s terms. High-pressure microwave digestion for the soil, UV irradiation for the wine. Then, I figure, inductively coupled plasma mass spectrometry for both.’
Enzo sat back shaking his head. ‘I guess the simple answer to my question was “no”. Here’s another one. How long will it take?’
‘A while. This is my busiest time of year.’
‘Could be that a man’s life is dependent on it.’
MacConchie nodded thoughtfully. ‘Okay. Two, three days. When do you fly back?’
‘Tomorrow.’
‘I’ll e-mail you the results.’ He leaned back and grinned. ‘But tonight you’ll meet my surgically perfected wife and taste my virtually perfected wines, and wallow in envy.’
But somehow Enzo didn’t think he would.

The hot California sun beat through the windscreen of his rental car as he cruised slowly through The Shores housing development in the Natomas district, north of downtown Sacramento. The houses on the north side of Hawkcrest Circle were built along the shores of a man-made lake where wild birds now mated and nested. It was only a short drive to the airport from here, and had he arrived by plane, Enzo would have seen the sun reflected in the water of the flood plains that stretched between the Sacramento River to the west and the American River to the south. This was where Gil Petty had bought his home when the money started coming in. It was where his marriage had foundered, a relationship malnourished by long and frequent absences.
Enzo blinked to try to stay awake. He had barely been able to keep his eyes open during dinner the night before, a problem not aided by the rich, red wines poured by the hand of Al MacConchie. Then, infuriatingly, he had been awake most of the night. And now, he was once again almost overcome by fatigue. Jetlag was the curse of the modern age.
He drew up outside a large house with wisteria growing around the gate to a courtyard entrance. Shrubs were in flower all along a bed below shuttered windows that faced out to the street. People preserved their privacy here. He walked up a short drive to the gate and pressed the bell. It rang somewhere distantly inside the house. He waited for what seemed like a very long time before the gate opened, and a small, sallow-skinned woman in black peered out at him from the shade. Beyond her, he could see a paved courtyard, shallow-pitched roofs sloping down to semitropical flowers. At the far end, a door opened into a large, airy room with a floor to ceiling view out across the lake.
‘Enzo Macleod for Mrs. Petty. She’s expecting me.’
Linda Petty was smaller than he had been expecting. Small but perfectly formed, and he saw where Michelle had got her looks, if not her height. She wore jeans that tapered to her ankles, and white, high-heeled sandals. Her cream top dipped low to show off the deep cleavage of her silicon implants and was cut short at the waist to reveal her tanned belly. Although still an attractive woman, her face had that stretched quality created by plastic surgery which drew loose flesh up behind the ears, leaving unnaturally high cheekbones and almond-shaped eyes. Her skin was too smooth, almost shiny, like plastic. Blond-streaked hair was cut short and tucked, like her face, behind her ears. Only the brown spots on the backs of veiny hands betrayed her age.
He followed her through into the dining room, and noticed her trim buttocks and narrow thighs, wondering how much of that was down to exercise and how much to liposuction. The theme of floor-to-ceiling glass continued here, like a giant screen showing constant re-runs of the lake beyond. One complete wall of the dining room was divided into beechwood pigeon-holes behind glass, a giant wine-rack filled with priceless bottles.
‘It’s sealed and refrigerated,’ she said. ‘Kept at a constant twelve degrees.’ She smiled condescendingly. ‘Celsius, of course. He liked to think he was so European. His wine wall, he called it. Broke his heart to lose it in the divorce settlement.’ She slid open glass doors and stepped out on to the deck. It was north-facing here, so shaded from the sun. Steps led down to a small pleasure boat bobbing on the water. She eased herself into a cushioned mahogany sun chair and lifted her legs on to an equally cushioned footstool. She lit a cigarette and blew smoke at the sky. ‘What is it you think I can tell you, Mister Macleod?’
Enzo squatted down on the edge of another cushioned footstool. ‘Who might have killed him.’
She smiled. ‘Not me, if that’s what you’re thinking. After the divorce, I had everything I’d ever wanted. It was my daughter who inherited the leftovers. But, of course, you said you’d met her.’
Enzo nodded. ‘She’s in France to recover her father’s belongings.’
Linda Petty looked unimpressed. ‘Is she? Took her time, then.’
‘Did you ever go with him on any of his wine tastings abroad?’
‘In the early days, yes. It was fun, then. We had a laugh and got drunk a lot. But the novelty soon wore off.
