I wiped the smeared mascara from Paula's cheeks. 'Even so, I'm still surprised.'

'At me? For God's sake, I was bored stiff. Working at the Clinic all day, and then sitting on the balcony and watching my tights dry. Bobby Crawford made everything seem exciting.'

'Paula, I understand. How many movies has he shot?'

'A dozen or so. That was the only one I filmed. The rape scene frightened me.'

'Why were you wearing a swimsuit-you look as if you're about to join in?'

'Charles…!' Exasperated with me, Paula lay back against the pillow, scarcely caring whether I approved of her or not. 'I'm a doctor here. Half the people seeing that film were my patients. Crawford had masses of copies made. Taking my clothes off was a way of disguising myself. You were the only one who wasn't fooled. You and Betty Shand – she loved the film.'

'I bet she did. You didn't help to make any others?'

'No fear. Crawford was talking about snuff movies. He and the chauffeur, Mahoud, were going to pick up some dim tourist in Fuengirola and bring her to his apartment.'

'He wouldn't have gone that far. Crawford was turning you on.'

'You're wrong!' Paula took my hands, like a serious schoolgirl at her first biology class who had glimpsed the realities of the living world. 'Listen to me, Charles. Bobby Crawford is dangerous. He set fire to your car, you know.'

'Possibly. This fellow Mahoud or Sonny Gardner would have carried it out. The fire wasn't what you think it was. It was a playful gesture, like some off-beat recorded voice on an answer-phone.'

'A playful gesture?' Paula turned to grimace at my neck. 'And the strangling? How playful was that? He could have killed you.'

'You think that was Crawford?'

'Don't you?' Paula shook my arm, as if trying to wake me. 'You're the one playing the dangerous games.'

'Perhaps you're right about Crawford.' I put my arm around her waist, remembering with affection how we had embraced, and thought of the hands clamped over my throat. 'I assumed it was him, part of the hazing that new recruits go through. He wants to draw me into his world. One thing puzzles me, though, and that is how he got into the apartment. Did he arrive with you?'

'No! Charles, I wouldn't have left you alone with him. He's too unpredictable.'

'But when we collided in the bedroom you said something about not playing that game any more. You took for granted it was Crawford.'

'Of course I did. I assumed he'd let himself in with a spare set of keys. He likes jumping out on people – especially women-coming up behind them and grabbing them in car parks.'

'I know. I've seen him at it. According to Elizabeth Shand, it keeps you on your toes.' I touched the almost vanished bruise on Paula's lip. 'Is that one of Crawford's little efforts?'

She lowered her jaw and revolved it in its sockets. 'He came to see me on the night of the Hollinger fire. The idea of all those terrible deaths must have excited him. I had to wrestle him off in the elevator.'

'But you picked him up from the beach after the speedboat chase? I saw you at his apartment the next day, bandaging his arm.'

'Charles…' Paula hid her face in her hands, and then smiled at me with an effort. 'He's a powerful figure, it's not easy to say no to him. If you've once been involved with him you find that he can draw on you whenever he wants to.'

'I understand. Could he have started the Hollinger fire?'

'He might have done. One thing leads so quickly to another – he can't control his imagination. There'll be other fires like your car and that speedboat, and more people will be killed.'

'I doubt it, Paula.' I stepped on to the balcony and gazed at the ruined mansion on its hill-top. 'Estrella de Mar is everything to him. The speedboat fire and my car were pranks. The Hollinger deaths were different – someone set out coldly to murder those people. That isn't Crawford's style. Could the Hollingers have been killed in some turf war over drugs? There are silos of cocaine and heroin sitting here.'

'But all controlled by Bobby Crawford. No other supplier gets a look in. Betty Shand and Mahoud see to it. That's why the heroin here is so pure. People thank Crawford for that-no infections, no accidental overdoses.'

'So the dealers work for Crawford? That didn't help Bibi Jansen and Anne Hollinger. They ended up in your Clinic.'

'They were addicted long before Bobby Crawford met them. But for him they'd both have died. He isn't trying to make money from drugs – Betty Shand takes all the profits. Medicinal-quality heroin and cocaine are Crawford's answer to the benzo-diazepines we doctors love so much. He once told me I was putting people under house arrest inside their own heads. For him heroin and cocaine and all these new amphetamines represent freedom, the right to be a crashed-out bar-kook like Bibi Jansen. He resents Sanger for taking her away from the beach, not for having sex with her.'

'He denies that he did.'

'Sanger can't face that side of himself Paula began to remake her lips in the dressing-table mirror, frowning at a still-loose canine under her bruise. 'For some people, even in Estrella de Mar, there are limits.'

She began to brush her hair with strong, efficient strokes, eyes avoiding me while she mentally prepared for her meeting with Frank. As I watched her through the mirror I had the sense that we were still inside a film, and that everything taking place between us in the bedroom had been prefigured in a master script that Paula had read. She was fond of me, and enjoyed making love, but she was steering me in a direction she had chosen.

'Frank will be sorry not to see you,' she told me as I carried the case to the door. 'What shall I tell him?'

'Say that… I'm meeting Bobby Crawford. There's something important he wants to discuss.'

Paula pondered the stratagem, unsure whether she approved. 'Isn't that a little devious? Frank won't mind you meeting Crawford.'

'It might trigger something if he thinks I'm trying to take his place. It's a long shot.'

'All right. But be careful, Charles. You're used to being an observer, and Bobby Crawford likes everyone to take part. You're getting too interested in him. When he sees that he'll swallow you whole.'

After a moment's reflection she leaned forward and kissed me, lightly enough not to disturb her lipstick, and long enough to leave me thinking of her for an hour after the elevator doors closed behind her.

The porsche turned into the Calle Oporto, pausing to inspect the sunlight like a shark orientating itself above an unfamiliar sea-bed. I lay back in the Citroen's passenger seat, a copy of the Wall Street Journal over my chest, unnoticed among the dozing taxi-drivers who used the shadow side of the street for their after-lunch siestas. The Sanger villa stood across the road, windows shuttered, the surveillance camera fixed on the litter of cigarette packets and advertisement flyers in the drive. Pushed by the wind, they edged towards the graffiti-covered doors of the garage, as if hoping to be incorporated into this lurid collage.

Crawford moved the Porsche at walking pace down the street, and stopped to glance at the silent villa. I could see the tendons working in his neck, jaws clenched while his lips mouthed whatever harsh words he had prepared for the psychiatrist. He accelerated sharply, then braked and reversed through the open gates. He stepped on to the unswept gravel and stared at the windows, waiting for Sanger to emerge and confront him.

But the psychiatrist had abandoned the villa, resettling himself a mile down the coast in one of his bungalows at the Residencia Costasol. I had watched him leave the previous afternoon, sitting with the last of his books in a Range Rover driven by a middle-aged woman-friend. He had closed the gates before leaving, but during the night vandals had jemmied the locks on both the gates and the garage.
