‘Consumer affairs programme,’ Carradine explained. ‘It’s very popular. Customers come on, talk about their shopping experiences. The Metro-Centre has its own cable channel. In the evenings we have higher ratings than BBC2.’

‘People go home and watch programmes about shopping?’

‘More than shopping, Mr Pearson. Health and lifestyle issues, sports, current affairs, key local concerns like asylum seekers . . .’

A monitor in the control room had come on, and a familiar face appeared, with the same deep tan and sympathetic smile that I had seen on the giant screens at the football stadium.

THE FACE FOLLOWEDus around the dome, its sunbed charm glowing from the television screen in Carradine’s office, a windowless space deep in the dome’s administration area. As I sipped a double espresso, glad to sink my nose in its reassuring vapour, Carradine sorted through the photographs he had pulled from his filing cabinet.

He and his assistants had spent endless hours editing out any bloodstains or panic-filled faces. The surveillance-camera stills he passed to me showed a retreat as calm and heroic as Dunkirk, younger customers helping the elderly, uniformed staff guiding children towards their grateful parents. Spilled shopping bags, scattered groceries, a screaming three-year-old with a blood-smeared face were all cropped and consigned to that vast amnesia that the consumer world reserved for the past. At the sales counter, the human race’s greatest confrontation with existence, there were no yesterdays, no history to be relived, only an intense transactional present.

I dropped the photos on Carradine’s desk and turned to the television screen where the suntanned presenter was interviewing housewives about their experiences with a new reusable cat litter. I guessed that the recorded clip would not be appearing on air.

‘I’ve seen him before,’ I told Carradine. ‘Years ago. EastEnders, The Bill.He tended to play paedophiles and widowers who’d murdered their wives . . . it’s that faint shiftiness.’

‘David Cruise.’ At the sound of the name Carradine straightened his shoulders. ‘He runs the Metro-Centre cable channel. He’s very popular, our customers like him.’

‘I bet. He fronted a few product launches for us. I remember a cinema ad for a new micro-car. He was too big to get into it and we had to drop him. The television screen is small enough for him.’

‘He’s good. We’re all glad he’s here. The local constituency chairman thinks he’d make a great Member of Parliament.’

‘He would. Today’s politics is tailor-made for him. Smiles leaking everywhere, mood music, the sales campaign that gets rid of the need for a product. Even the shiftiness. People like to be conned. It reminds them that everything is a game. No disrespect—’

There was a rapid knock on the door and Carradine’s secretary burst in. Close to tears, she spoke urgently to Carradine, then paused by the door as he picked up his telephone.

‘Christie? What do you mean?’ As he listened he struck his mouth with the palm of his hand. ‘When? The court? Mr Pearson is here. How do I explain that?’

He held the receiver in one hand and carefully depressed the cradle with the other, staring at the photographs on his desk.

‘Tom? What’s the problem?’ I walked around the desk. ‘Family news?’

‘Your family.’ Carradine pointed the receiver at me. ‘Duncan Christie.’

‘What about him? Is he dead? Don’t tell me he hanged himself in his cell?’

‘He’s alive.’ Carradine stepped back, trying to leave as much space as possible between us. He stared in a level way at me, unsure whether I would be able to cope with his news. For the first time he no longer looked like a teenager. ‘Very much alive. There was a special court hearing this morning. It just ended. The magistrate discharged him. He ruled there was no case to answer.’

‘How? I don’t believe it.’ I seized the telephone receiver from Carradine and pressed it hard into its cradle, trying to silence this absurd oracle. ‘It’s a hoax. Or a cock-up, some legal blunder. They’re talking about a different case.’

‘No. It’s Duncan Christie. The Crown Prosecution Service offered no evidence. The police withdrew their charges. Three witnesses have come forward, saying they saw Christie in the South Gate entrance hall when the shots were fired. They picked him out in a line-up. Christie was nowhere near the mezzanine. I’m sorry, Mr Pearson . . .’

I turned away, and stared at the presenter still smiling and teasing his housewives. I felt dazed, but I noticed that David Cruise preferred his left profile, which concealed the receding hairline above his right temple. In an almost reassuring way, his soft and ingratiating presence offered the only reality in the absurd world that my father’s death and the Metro-Centre had created between them.

GOING HOME

I EXPECTED TO FIND a noisy crowd outside the magistrates’ court, but the police outnumbered the few spectators. Passers-by paused on the pavement opposite the court, but the last of the photographers were packing away their equipment, deprived of their target.

Tuning to the local radio bulletin as I drove from the Metro-Centre, I heard the news confirmed. I drummed my fists on the steering wheel, certain that the law had tripped over itself. I had seen Christie close enough to punch him, and his lolling head and wandering eyes, a visible attempt to escape from himself, convinced me that he was guilty. Somehow I had to overturn this misguided and ludicrous decision. The large vacuum left in my life by my father’s murder had now been invaded by another vacuum.

I left the Jensen on a double yellow line, waving to the policeman who studiously said nothing when I walked past him. I was climbing the courthouse steps when I saw Sergeant Falconer emerging through the doors. She recognized me and began to turn away, pretending to adjust her hair. Unable to escape, she rallied herself and took my arm in a firm grip.

‘Mr Pearson . . . ?’ Her mind seemed miles away, but she steered me into the lobby, past three uniformed constables rocking on their heels. ‘You’ve heard? It’s quieter in here. The public . . .’

‘Don’t worry, they’ve all gone shopping. No one seems upset, or surprised.’

‘Believe me, it’s a complete surprise.’ Sergeant Falconer studied my face, relieved to find me on the edge of anger, an emotion with which her training had taught her to cope. She led me to a bench. ‘Let’s sit here. I’ll do my best to give you any details.’

‘Can’t we go in? Civic awareness, and all that. Everyone should observe a miscarriage of justice.’

‘The court is closed.’ She smiled in a sisterly way and touched my arm. ‘Mr Christie may be coming out soon. Is that all right . . . ?’

‘Fine. He’s innocent, isn’t he?’ I watched the constables sauntering about the steps, truncheons reluctantly sheathed, like salesmen deprived of their customers. Without thinking, I said: ‘The police sell violence.’

‘What?’

‘The idea of violence.’ I laughed to myself. ‘Sorry, Sergeant.’

‘You’re upset. It’s understandable.’

‘Well . . .’ I calmed myself, touched by her close interest. ‘Half an hour ago I was sure who had killed my father, and why. A mental patient with a grudge against a shopping mall. Now, suddenly, it’s a mystery again. Brooklands, the M25, these motorway towns. They’re damned strange places. Nothing is what it seems.’

‘That’s why people move here. The suburbs are the last great mystery.’

‘Is that the reason you’re leaving?’ I took her hand, surprised by its almost feverish warmth. There was an operation scar on the knuckle of her ring finger, the trace of an old tendon injury left by some hooligan with a beer bottle. Or had a tenacious engagement ring been surgically removed, her body holding on to a passion that her quirky mind repressed? Sergeant Falconer was wary and defensive, and not only about the confused police investigation into my father’s death. I knew that she wanted me out, safely back in central London, but I sensed that she wanted herself out, free from whatever web was spinning itself around her.
