This time, however, merchandise of a different kind was being delivered. From the trunk of the Mercedes the young Germans lifted a computerized cash-register. Elizabeth Shand broke off her tete-a-tete with Hennessy and beckoned me towards her. Despite the heat, her immaculate make-up was untouched by the slightest hint of perspiration. A cooler blood chilled her veins, as if her predatory mind worked best at temperatures lower than the heart's. As always, though, her lips parted generously when she greeted me, holding out the promise of an erotic encounter so strange that it might jump the species barrier.

'Charles, how good of you to be here so early! I do value keenness. These days no one wants anything to be a success, as if failure were somehow chic. I've brought something that should help to make the profits sing. Show Helmut and Wolfgang where you want it.'

'I'm not sure.' I stood back to let the Germans carry the computer into the foyer. ' Elizabeth, it's a great show of confidence in us, but don't you think it's a little premature?'

'Why, dear?' She pressed her veiled cheek to mine, her handsome body sheathed in a cascade of silks that rustled against my bare chest like the plumage of a tremulous bird. 'We must be ready when the flood comes. Besides, you won't be able to cheat me, or not quite so easily.'

'I'll happily cheat you – it sounds rather exciting. It's just that we haven't had a single recruit. Not one resident has applied to join the club.'

'They'll come. Believe me.' She waved to the Keswick sisters, who were pacing out an area of the terrace behind the bar, as if defining the margins of an open-air restaurant. 'There'll be so many new attractions that no one will be able to resist. Don't you agree, David?'

'Absolutely.' Hennessy stood by the concierge's counter, his arm around the computer, welcoming a new confederate in crime. 'I'm sure we'll be as busy as the Club Nautico.'

'You see, Charles? I'm completely confident. We may have to build out on to the car park, and lease parking space from the marina.' She turned to the docile young Germans, waiting in their tennis whites for her next command. 'Wolfgang and Helmut – I think you've already met them, Charles. I want them to help you here. They can move into the apartment upstairs. From now on they work for you.'

I shook hands with the Germans. As if embarrassed by their own musculatures, they bounced lightly on their feet, huge knees moving like bronzed piston heads, forever trying to rearrange their bodies in some less self-conscious configuration.

'Good… but, Elizabeth, what exactly will they do?'

'Do?' She patted my chin, pleased by my teasing. 'They will do nothing. Wolfgang and Helmut will "be". They will be themselves and become very popular. I know about these things, Charles. As it happens, Helmut is extremely good at tennis – he once beat Boris Becker. And Wolfgang is a frightfully good swimmer. He's covered enormous distances in the Baltic Sea.'

'Useful… getting from one side of the Jacuzzi to the other is more than most people here can manage. So they could be sports coaches?'

'Exactly. I know you'll put their talents to good use. All their talents.'

'Naturally. They can help with the recruitment drive.' I accompanied her to the limousine, where Mahoud stood beside the open passenger door, heavy jowls sweating under his peaked cap. 'The club does need new members-I thought I might mail a few leaflets. Or hire a plane to fly around the Residencia every day with a banner. Free tennis lessons, aerobics classes, massage and aromatherapy, that sort of thing…?'

Elizabeth Shand smiled at Hennessy, who was carrying her briefcase to the car. The underwriter seemed equally amused, frisking up the ends of his moustache, eager for them to join in the fun.

'Leaflets and banners? I don't think so.' She took her seat, settling herself in a bower of silks. When Mahoud had closed the door she reached through the window to squeeze my hand reassuringly. 'We need to wake everyone up. The people at the Residencia Costasol are desperate for new vices. Satisfy them, Charles, and you'll be a success…'

Her confidence that unknown sins existed, still waiting to be discovered, altogether surprised me. I watched the limousine cross the plaza on its return to Estrella de Mar. Workmen were removing the Verkauf and A Vendre signs from the untenanted retail units beside the supermarket, but the sports club remained silent. I walked around the empty building, and listened to my feet ring on the polished floor. The Germans lounged by the pool, showing off their physiques to each other. A desultory traffic moved around the plaza, and by noon the Residencia Costasol was already preparing for its afternoon retreat from the sun.

Despite myself, I felt responsible for the club's failure to attract new members, and realized how depressed Frank must have been when he first arrived at the Club Nautico. I stood behind the concierge's counter, watching the waiters pace around the open-air bar and the groundsmen sweep the deserted tennis courts.

I was pointlessly keyboarding the computer, adding up imaginary profits, when I heard the beat of a Porsche's engine thrumming through the sunlight. I reached the glass doors as Bobby Crawford crossed the car park. He sprinted up the steps, bounding on his powerful legs like an acrobat on a trampoline, an arm raised to greet me. He wore his black baseball cap and leather jacket, and carried a large sports bag in one hand. Seeing him, I felt my heart begin to race.

'Charles? Chin up. This isn't the House of Usher.' He took the door from me and stepped into the foyer, eager smile exposing the iceberg whiteness of his polished teeth. 'What's been happening? You look as if you're glad to see me.'

'I am. Nothing's happened – that's the problem. I may be the wrong manager for you.'

'You're tired, Charles. Not a time to get depressed.' Crawford glanced at the pool and tennis courts. 'A lot of hunk in place but no customers. Any new members?'

'Not one. Maybe tennis isn't what the people here need.'

'Everyone needs tennis. The Residencia Costasol may not know it now, but it soon will.'

He turned to face me, beaming warmly and clearly happy to find me waiting for him, and already seeing my grumpy mood as one of the amusing foibles of a family retainer. He had been away for four days, and I was struck by how much more sharply tuned his movements were, as if he had installed a more powerful engine in the Porsche and drawn off part of its huge thrust for his own nervous system. Grimaces and little tics crossed his face as a hundred and one ideas jostled in his mind.

'Things are going to happen here, Charles.' He gripped my shoulder like an older brother, nodding his approval at the cash register. 'Holding the fort isn't easy. Let me tell you, Betty Shand is proud of what you've done.'

'I've done damn-all. Nothing is going to happen here. The Residencia Costasol isn't your sort of place. This isn't Estrella de Mar, it's the valley of the brain-dead. I only wish I could help.'

'You can. By the way, I think I've found a house for you-small swimming pool, tennis court, I'll bring over a tennis machine so you can practise your returns. First I have a few calls to make. We'll take your car – I'd like you to drive. That slow and steady pace of yours soothes my headaches.'

'Of course.' I pointed to the clock in the foyer. 'Do you want to wait? It's two-forty-five. Everything here is in deep sleep.'

'Perfect-it's the most interesting time of day. People are either dreaming or having sex. Perhaps both at the same time…'

As I started the engine he settled himself into the passenger seat of the Citroen, one arm trailing out of the window and the hold-all between his legs. He nodded approvingly as I fastened my seatbelt.
