'Exactly. The place was filled with your patients. Not so many now, I dare say.'

'Almost none at all.' She placed her valise on my desk and sat beside it, nodding to herself. 'A few leukaemias I send back to London. Shin-splints from all this unnecessary exercise. Even a few cases of VD. But a little old-fashioned gonorrhoea wouldn't surprise you.'

'Not really.' I shrugged tolerantly. 'You'd expect it, given a bigger turnover of sexual partners. It's a disease of social contact – like flu, or golf.'

'There are other social diseases, some a lot more serious -like a taste for kiddie-porn.'

'Pretty rare in the Residencia.'

'But surprisingly contagious.' Paula treated me to her severest schoolmistressy gaze. 'People who think they're immune suddenly catch a rogue cross-infection from all the other porn they're looking at.'

'Paula… we've tried to keep it down. There's a problem in the Residencia-there are almost no children. People miss them, so sexual fantasies get mixed up with nostalgia. You can't blame Bobby Crawford for that.'

'I blame him for everything. And you – you're almost as responsible as Crawford. He's totally corrupted you.'

'That's absurd. I'm planning a book, thinking about guitar lessons and a stage career, playing bridge again…'

'All noise.' Paula picked up the computer mouse and held it tightly in her hand, as if wanting to crush it. 'When you came here you were the homme moyen sensuel, full of hang-ups about your mother and little guilts about those teenaged whores you fuck in Bangkok. Now you haven't a moral care in the world. You're the right-hand man of the local crime czar and you aren't even aware of it.'

'Paula…' I reached out and tried to rescue the mouse from her. 'I've more doubts than you realize.'

'You're deluding yourself. Believe me, you totally support him.'

'Of course I do. Look at what he's achieved. I couldn't give a damn how many sculpture classes there are, the important thing is that people are thinking again, looking hard at who they are. They're building a meaningful world for themselves, not just fitting more locks to the front door. Everywhere you look – Britain, the States, western Europe – people are sealing themselves off into crime-free enclaves. That's a mistake-a certain level of crime is part of the necessary roughage of life. Total security is a disease of deprivation.'

'Maybe.' Paula stood up and strolled around the office, shaking her head at the festive tourists. 'He leaves tomorrow, thank heavens. What are you going to do when he's gone?'

'Things will run as before.'

'Are you sure? You need him. You need that energy and wide-eyed innocence.'

'We'll live without it. Once the carousel is spinning it doesn't need all that much of a push to keep it moving.'

'So you think.' Paula stared at the distant pueblos along the coast, their white walls lit by the sun. 'Where is he going?'

'Further down the beach. Calahonda – it's a huge complex. There are something like ten thousand Brits there.'

'They've got a surprise in store. So he's moving on, bringing cordon bleu and tango classes to the benighted people of the pueblos. He'll recruit another edgy wanderer like you and, at the snap of a few Polaroids, the poor man will see the light.' She turned to face me. 'You'll be at Frank's trial tomorrow?'

'Of course I will. That's why I came here.'

'Are you sure?' She sounded sceptical. 'He needs you. You haven't been even once to the jail in Malaga. Not once in nearly four months.'

'Paula, I know…' I tried to avoid her eyes. 'I should have been to see him. That guilty plea threw me – I felt he was trying to involve me in whatever troubled him. I wanted to crack the Hollinger case, and then Bobby Crawford came along. I felt a load off my shoulders But Paula was no longer listening to me. She stepped to the window as the last of the floats arrived, bearing a mock-sunset of pink roses on which was superimposed 'The End'. A boisterous party was in progress on the float, and a dozen younger residents of the Costasol complex performed a dance medley to music played by a three-piece band. Knees and elbows scissored through a few bars of the Charleston, arms whirled in a forties jitterbug, hips gyrated through the twist.

In the centre of the dancers Bobby Crawford kept time, clapping as he led the troupe through the hokey cokey and the black bottom. His Hawaiian shirt was soaked with sweat, and he seemed to be on a cocaine high, his eyes raised to the clouds of confetti and petals as if he were ready to rise from the dance floor and float away among the helium balloons.

Not all the dancers, however, would join him. Stumbling beside Crawford was the derelict and exhausted figure of Laurie Fox, barely able to lift her feet to the music. Several beats behind, she lurched into the dancers around her and then fell against Crawford's chest, mouth ajar below her unfocused eyes. Her hair had grown into a fuzzy black pelt, through which the scars were still visible like failed attempts to trepan herself. Her grimy vest was stained with blood that had run from her bruised nose, and outlined her breasts as they rolled like moony heads.

As we watched, she fell to the floor, vomited among the petals and began to hunt for the nose-ring that had escaped from her bloody nostril. Barely breaking his dance-step, Crawford lifted her on to her feet, encouraging her with an eager smile and a brief slap.

'Poor child…' Paula hid her face behind one hand as the other reached for the security of her medical valise. 'She's probably had nothing for weeks except tequila and amphetamines. Can't you get Crawford to help her?'

'He has. I'm not being callous, Paula. She's doing what she wants, terrible though it is. Crawling towards her own death 'What on earth does that mean? And what happens when he goes? Will he take her with him?'

'Maybe. I doubt it.'

'He's used her, letting her degrade herself to excite everyone else.'

'This isn't her best day-the festival's too much for her. They love her down at the marina. She sings in a jazz bar by the boatyard. Even Andersson's climbed out of his gloomy shell and started to forget Bibi Jansen. She's better off there than lying in some drug-induced coma at the Princess Margaret Clinic. The sad thing is, you're not the only one who doesn't understand that.'

I pointed to the float as it circled the plaza, the band working itself into a final flourish. Laurie Fox had given up and now sat on the floor among the vomit and dancing feet. Walking abreast of her through the crowd was Dr Sanger, one hand raised in an attempt to touch her shoulder. With a determination that seemed surprising in this slim and diffident man, he pushed the tourists and cameramen out of his way and kept a protective eye on the young woman, calling to her when she seemed to fall asleep. Since her departure from the bungalow he had roamed the streets and cafés of the Residencia, content to catch a glimpse of her shouting from the passenger seat of Crawford's Porsche or shrieking from his speedboat as it sped down the canal to the open sea. I often watched him pacing around his pool and compulsively washing the discarded nightdress. When the float circled the shopping mall I waited for Sanger to leap aboard, but Crawford was unaware of the psychiatrist, his head raised to the sun as he danced through the shower of petals.

'Poor man… I hate that.' Paula turned her back to the scene and paced around my desk. 'I'm going-you'll be at court tomorrow?'

'Of course. But we'll meet at the party tonight.'

'The party?' Paula seemed surprised. 'Where – at your villa?'

'It starts at nine. Hennessy should have phoned you. It's Bobby Crawford's farewell. We're giving him a special send-off. I'll see you there.'

'I'm not sure. A party…?' Paula fiddled with her valise, as if unable to cope with the notion. 'Who will be coming?'
