'Keep an eye on this club. Betty Shand has bought out the lease – we re-open in three weeks' time. We need someone to run the place for us.'

'I'm the wrong man. You need a trained manager. I can't hire and fire staff, keep accounts and run a restaurant.'

'You'll soon learn.' Confident that he had recruited me, Crawford gestured dismissively at the bar. 'Besides, there's no restaurant and Betty will do the hiring and firing. Don't worry about the accounts – David Hennessy has all that under control. Join us, Charles. Once we get the tennis club going everything else will follow. The Residencia Costasol will come alive again.'

'After a few games of tennis? You could stage Wimbledon here and no one would notice.'

'They will, Charles. Of course, there'll be more than tennis. When they set up the Costasol complex there was one ingredient missing.'

'Work?'

'Not work, Charles. No.'

I waited as he gazed at the silent villas around the plaza and the cameras on the lamp standards that tracked the cars leaving the shopping mall. His open and eager face was touched by a determination that Frank must have found equally intriguing.

The modest sports club with its shabby courts and drained pool was a far cry from the Club Nautico, but by pretending to manage it I would draw closer to Crawford and Betty Shand, and might at last step on to the path that had led to the burning of the Hollinger mansion and Frank's absurd confession.

A yacht had entered the marina, a white-hulled sloop with furled sails, moving under its engine. Gunnar Andersson stood at the helm, his slim-shouldered figure as tall as a mizzen-mast, shirt floating from his shoulders like a strip of tattered sail. The craft seemed neglected, its hull smeared with oil, and I assumed that Andersson had sailed it through the tanker lanes from Tangier. Then I noticed the tag of yellow ribbon flying from the fore-rail, the last of the police tapes that had wrapped themselves around the craft.

'It's the Halcyon. Frank's sloop… what's it doing here?'

'That's right.' Crawford stood up and waved to Andersson, who doffed his cap in return. 'I talked to Danvila. Frank agrees the yacht will be safer in the Costasol marina-no tourists cutting off bits of rigging. Gunnar is going to work in the boatyard and start servicing all these arthritic engines. With a little luck we'll make the Costasol regatta the swankiest show on the coast. Believe me, Charles, sea air is what people need. Now, here's Elizabeth, looking more handsome every day. Bratwurst obviously agrees with her…'

The stretch Mercedes was turning into the car park of the sports club. Betty Shand lay back against the leather upholstery, a wide-brimmed hat screening her veiled face, a gloved hand jerking the passenger strap as if reminding the huge car of its rightful owner. The swarthy Maghrebian sat at the wheel, the two young Germans on the jump seats behind him. When the car stopped by the steps Mahoud sounded the horn, and a moment later David Hennessy and the Keswick sisters emerged from the Thai restaurant. Together they set off towards the club, bundles of property prospectuses under their arms.

A team was assembling in the central plaza of the Residencia Costasol. Crawford, Elizabeth Shand, Hennessy and the Keswick sisters were coming together, ready to discuss their plans for the complex and its residents. The manager of the Thai restaurant waved to his departing guests, little realizing that his menus would soon be changing.

'Betty Shand and the Keswicks…' I commented. 'The seafood's going to be good.'

'Charles? Yes, the Keswick girls are taking over the Thai place. They know what people need, always a big help. Now, have you thought about working for us?'

'All right,' I said. 'I'll stay until Frank's trial. But nothing too arduous.'

'Of course not.' Crawford leaned across the table and clasped my shoulders, smiling with unfeigned delight, and I sensed that for a few seconds I had become the most important person in his world, the one friend he had relied upon to come to his aid. As he beamed at me proudly his face seemed almost adolescent, blond hair spilling over his forehead, lips parted across immaculate white teeth. Squeezing me with his strong hands, he spoke in a rush of lightheaded words. 'I knew you would, Charles-you're the one person I need here. You've seen the world, you understand how much we have to do if we're going to help these people. By the way, a house comes with the job. I'll find you one with a tennis court, and we'll play a few games. I know you're a lot better than you let on.'

'You'll soon see. By the way, you can pay me a small salary. Living expenses, car-hire and so on. Since I'm not earning a cent any more…'

'Absolutely.' He sat back and gazed at me fondly as Elizabeth Shand made her imperial way into the club. 'David Hennessy's already written out your first cheque. Believe me, Charles, we've thought of everything.'

Sunlight crazed the broken surface of the swimming pool, as if released from the glassy depths by my dive. I swam a leisurely length, touched the tiled gutter and hoisted myself on to the diving board. The waves slapped the sides of the pool, refusing to calm themselves, and eager to applaud the next pre-breakfast swimmer in search of an appetite.

As I towelled myself, however, I guessed that another day would pass and I would remain the swimming pool's only customer, just as I would be the only visitor to the tennis courts and gymnasium. Killing time beside the open-air bar, reading the London newspapers and thinking about Frank's trial, I knew that time had died in the Residencia Costasol long before my arrival.

During my first week as 'manager' of the sports club I sat back and watched Elizabeth Shand's groundsmen re-vamp the entire premises. They cleaned and filled the pool, watered the lawns and white-inked the tennis courts, then buffed the hardwood floor of the gymnasium to a mirror-like finish, ready for the first aerobics classes.

Despite these efforts, and the expensive pool-side furniture waiting to cushion their exhausted limbs, none of the Costasol residents had put in an appearance. My hours, David Hennessy told me, ran from eleven a. m. to three p. m., but 'take as long as you want for lunch, dear boy, we can't have you going mad with boredom.'

Nevertheless, I usually drove from the Club Nautico before breakfast, curious to see if the dozing residents of the complex had been tempted to leave their balconies. Hennessy would arrive at noon, retreat to his office and return to Estrella de Mar once he had paid the waiters and ground staff. Sometimes Elizabeth Shand would visit him, arriving in her limousine with the two Germans. In a curious pantomime each would hold open a passenger door for her, while she gazed at the sports club like a predatory widow visiting an entailed property about to fall into her grasp.

Had her legendary business savvy deserted her for once? Eating my breakfast at the bar, surrounded by the silent waiters and the empty sun-loungers, I guessed that she might soon be writing off her investment and leaving for the richer pastures at Calahonda. The caravan would move on to the retirement pueblos of the coast, taking with it my last hopes of discovering the truth about the Hollinger fire.

Frank, absurdly, still maintained his guilt, and I had twice postponed my visit to Zarzuella jail, convinced against all the evidence that the Residencia Costasol might be a back door into the secret Estrella de Mar for so long closed to me. His trial had been set for 15 October, four months to the day after the tragic fire, and despite all my efforts I would be no more than a character witness. I thought constantly of Frank and our childhood years together, but found it almost impossible to face him across the hard table of a prison interview room. His plea of guilty had seemed to embrace us both, but I no longer felt the sense of shared guilt that had once united us.
