I felt the bruises on my neck, and realized that Crawford had been recruiting me when he stepped from the darkness and seized my throat. A laying-on of hands had taken place, as he appointed me to fill Frank's vacant role. By not injuring me he had made the point that the Hollinger murders were irrelevant to the real life of Estrella de Mar and the new social order sustained by his criminal regime.

Soon after midnight I was woken by a flash of light across the bedroom ceiling. I stepped on to the balcony and searched for the beacon of the Marbella lighthouse, assuming that an electrical discharge had destroyed the lantern. But the beam continued its soft circuit of the sky.

The flames leapt from the centre of the Costasol marina. A yacht was on fire, its mast glowing like a candlewick. Cut loose from its moorings, it drifted across the open water, a fire-ship searching the darkness for a phantom fleet. But after scarcely a minute the flames seemed to snuff themselves out, and I guessed that the yacht had sunk before Bobby Crawford could rouse the Costasol residents from a slumber even deeper than sleep. Already I suspected that the yacht was the Halcyon, and that Crawford had persuaded Andersson to sail the craft from its berth at Estrella de Mar, ready to signal his arrival to the peoples of his ministry.

The next morning, when I passed the marina on my way to the sports club, a police launch circled the debris-strewn water. A small crowd stood on the quay, watching a frogman dive to the submerged sloop. The usually silent yachts and cruisers had begun to stir with activity. A few owners were testing their rigging and engines, while their wives aired the cabins and buffed the brass. Only Andersson sat quietly in the boatyard, face as bleak as ever, smoking a roll-up cigarette as he stared at the rising sails.

I left him to his vigil and drove across the plaza to the club. A car turned through the gates ahead of me and parked by the entrance. Two middle-aged couples, dressed in their crispest tennis whites, stepped nimbly from the car, rackets swinging in their hands.

'Mr Prentice? Good morning to you.' One of the husbands, a retired dentist I had seen in the wine store, strolled up to me. 'We're not members, but we'd like to join. Can you sign us up?'

'Of course.' I shook his hand and beckoned the party towards the entrance. 'You'll be glad to know that the first year's membership is entirely free.'

Bobby Crawford's first recruits were signing on for duty.

The residencia costasol had come to life. A sun-bleached cadaver of a community, lying inertly beside a thousand swimming pools, had raised itself on one elbow to taste the quickening air. Waiting for Crawford to begin his morning inspection tour, I sat in the Citroen and listened to the eager chorus of hammers nailing together the proscenium arch of the open-air theatre beside the marina. Led by Harold Lejeune, a sometime marine surveyor at Lloyd's Register of Shipping, a team of enthusiastic carpenters was putting together a creditable copy of an end-of-pier playhouse.

Lejeune squatted astride the crown pole, baseball cap rakishly across his head, nails clamped in his strong teeth as he waited for the last section of the pitched gable to be hoisted into place. A furious salvo of hammerheads signalled the raising of the roof by this work-gang of former accountants, lawyers and middle-managers.

Below them, shielding their ears from the din, their wives were unrolling the bolts of silky bombazine that would form the side and rear walls of the theatre. A group of energetic daughters unloaded a stack of collapsible metal chairs from a pick-up truck beside the quay, adding them to the rows of seats that faced the stage.

The Marina Players were about to mount their first production, a performance of The Importance of Being Earnest, which would alternate with Who's Afraid of Virginia Woolf?.

Future productions included plays by Orton and Coward, all to be directed by Arnold Wynegarde, a Shaftesbury Avenue veteran, their amateur casts stiffened by several one-time stage professionals.

Green shoots of a forgotten metropolitan culture were poking through the property developer's plaster and lath. When the hammers paused briefly from their work I could hear the strains of Giselle from the gymnasium, where a ballet class of younger wives were practising their fouettes and arabesques. They would end the session bouncing in their leotards to a rock number, then lie panting by the swimming pool.

In the five weeks since Crawford had taken me on my first tour of the complex a remarkable transformation had occurred. Refurbished restaurants and boutiques had opened in the shopping mall, briskly profitable as they prospered under Elizabeth Shand's steely gaze. An impromptu arts festival had conjured itself from the air, drawing troupes of eager volunteers from the sleepy afternoons.

The Residencia Costasol had decided that it needed a facelift. A rush to activity of every kind was on, the quest for a new civic pride expressed in parties and barbecues, tea-dances and church services. Newsletters circulated on the e-mail computer screens, inviting residents to stand for a new municipal council and its projected sub-committees.

The sounds of serve and volley came from the tennis courts, where Helmut drilled his eager pupils, and there was a heavy splash in the swimming pool as Wolfgang demonstrated a jackknife and reverse swallow to his diving class. Water-skis, trampolines and exercycles were being moved by the groundsmen from forgotten storerooms under the gymnasium. Below the arched bridge of the coastal road the first yachts of the morning were setting out for the open sea. The once-silent marina echoed to the strains of capstan and hawser as hulls weakened by osmosis were drained and varnished by Andersson and his Spanish repair team.

Meanwhile, in the centre of the marina, a fire-ravaged sloop was lashed to a steel lighter, the half-submerged hulk of the Halcyon. Its charred mast and blackened sails presided over the waterways, urging the yachtsmen of the Residencia Costasol to reef their sails and search for the keenest winds and steepest seas.

A hand held my shoulder, then clasped my temples before I could raise my head, pinning me to the driving seat of the Citroen. I had fallen asleep in the car, and someone had slipped into the seat behind me.

'Bobby…!' I pushed his hand away, angered by his brutal humour. 'That's a -'

'Mean trick to play?' Crawford chuckled to himself like a child savouring a favourite joke. 'Charles, you were sound asleep. I hired you as my bodyguard.'

'I thought I was your literary adviser. You were supposed to be here at ten.'

'Pressing work. All kinds of things are happening. Tell me, what were you dreaming about?'

'Some sort of… fire-storm. The yachts in the marina were blazing. God knows why.'

'Strange. Did you wet the bed as a child? Never mind. How's everything at the club? It sounds busy.'

'It is. Membership's up to three hundred, with another fifty application forms in. There's already a waiting list for the courts.'

'Good, good…' Crawford scanned the pool, smiling at the sight of so many handsome women oiling themselves in the sun. Wolfgang was demonstrating a back-flip, whipping the board under his feet with a crack that roused everyone from their seats. 'Handsome fellow-any Greek sculptor would have given his eye-teeth to stick him in a frieze. It looks great, Charles. You've done a superb job. You may not realize it, but your real ambition is to run a nightclub in Puerto Banus.'

He patted my back and gazed at the busy scene, smiling in an almost innocent way, delighted by these signs of civic renewal and at that moment wholly unconscious of the means he had used to achieve them. Despite myself, I was glad to see him. As always I felt buoyed by his evangelical zeal and his selfless commitment to the people of the Residencia. At the same time I was still sceptical about his belief that the crime wave he had launched was the engine of change. The theatre and sports clubs, like their counterparts at Estrella de Mar, flourished as a result of some small but significant shift in people's sense of themselves, a response to something no more radical than simple boredom. Crawford had seized on the coincidence to give vent to a latent strain of violence in his make-up, an almost childlike faith that he could provoke the world to rise on its toes and respond in kind. Just as he had willed the tennis machine to beat him, he now urged the Costasol complex to rally itself against the secret enemy within its walls.
