First he felt nothing but shock; then quickly a sense of a monstrous error.

And a great fear. Because Fabian understood immediately that it would be easy for them to believe that Saul had killed his father. And, as immediately, he knew without any equivocation or doubt that Saul had not. But he was terribly afraid, because only he knew that, because he knew Saul. And there was nothing he could tell others to help them understand.

He wanted to see Saul; he did not understand why the officer’s voice changed when he demanded this. He was told it would be some time before he could speak to Saul, Saul was deep in conversation, his attention wholly grabbed, and Fabian would just have to wait. There was something the man was not telling him, Fabian knew, and he was scared. He left his phone number, was reassured that he would be contacted as soon as Saul was free to speak.

Fabian sped along Acre Lane. On his left he passed an extraordinary white building, a mass of grubby turrets and shabby Art Deco windows. It looked long deserted. On the step sat two boys, dwarfed by jackets declaring allegiance to American Football teams neither had ever seen play. They were oblivious to the faded grandeur of their bench. One had his eyes closed, was leaning back against the door like Mexican cannon-fodder in a spaghetti Western. His friend spoke animatedly into his hand, his tiny mobile phone hidden within the voluminous folds of his sleeve, Fabian felt the thrill of materialist envy, but battened it down. This was one impulse he resisted.

Not me, he thought, as he always did. I’ll hold out a bit longer. I won’t be another black man with a mobile, another troublemaker with ‘Drug Dealer’ written on his forehead in script only the police can read.

He stood up out of his seat, kicked down and sped off towards Clapham.

Fabian knew Saul hated his father’s disappointment. Fabian knew Saul and his father could not speak together. Fabian had been the only one of Saul’s friends who had seen him turn that volume by Lenin over and over in his hands, open it and close it, read the inscription again and again. His father’s writing was tight and controlled, as if trying not to break the pen. Saul had put the book in Fabian’s lap, had waited while his friend read.

To Saul, This always made sense to me. Love from the Old Leftie.

Fabian remembered looking up into Saul’s face. His mouth was sealed, his eyes looked tired. He took the book off Fabian’s lap and closed it, stroked the cover, put it on his shelf. Fabian knew Saul had not killed his father.

He crossed Clapham High Street, a concourse of restaurants and charity shops, and slid into the back streets, wiggling through the parked cars to emerge on Silverthorne Road. He started down the long incline towards the river.

He knew that Natasha would be working. He knew he would turn into Bassett Road and hear the faint boom of Drum and Bass. She would be hunched over her keyboard, twiddling dials and pressing keys with the concentration of an alchemist, juggling long sequences of zeros and ones and transforming them into music. Listening and creating. That was what Natasha spent all her time doing. When she was not concentrating on source material behind the till of friends’ record shops, serving customers in an efficient autopilot mode, she was reconstituting it into the tracks she christened with spiky one-word titles: Arrival; Rebellion; Maelstrom.

Fabian believed it was Natasha’s concentration which made her so asexual to him. She was attractive in a fierce way, and was never short of offers, especially at clubs, especially when word got around that the music playing was hers; but Fabian had never known her seem very interested, even when she took someone home. He felt blasphemous even thinking of her in a sexual context. Fabian was alone in his opinion, he was assured by his friend Kay, a cheerful dope-raddled clown who drooled lasciviously after Natasha whenever he saw her. The music was the thing, Kay said, and the intensity was the thing, and the carelessness was the thing. Just like a nun, it was the promise of what was under the habit.

But Fabian could only grin sheepishly at Kay, absurdly embarrassed. Amateur psychologists around London, Saul included, had wasted no time deciding he was in love with Natasha; but Fabian did not think that was the case. She infuriated him with her style fascism and her solipsism, but he supposed he loved her. Just not in the way Saul meant it.

He twisted under the filthy railway bridge on Queenstown Road now, fast approaching Battersea Park. He was riding an incline, racing towards Chelsea Bridge. He took the roundabout with casual arrogance, put his head down and climbed towards the river. On Fabian’s right, the four chimneys of Battersea Power Station loomed into view. Its roof was long gone, it looked like a bombed-out relic, a blitz survivor. It was a great upturned plug straining to suck voltage out of the clouds, a monument to energy.

Fabian burst free of South London. He slowed and looked into the Thames, past the towers and railings of steel that surrounded him, keeping him snug on Chelsea Bridge. The river sent shards of cold sunlight in all directions.

He scudded over the face of the water like a pond skater, dwarfed by the girders and bolts ostentatiously holding the bridge together. He hung poised for a moment between the South Bank and the North Bank, his head high to see over the sides into the water, to see the black barges that never moved, waiting to ferry cargo long forgotten, his legs still, freewheeling his way towards Ladbroke Grove.

The route to Natasha’s house took Fabian past the Albert Hall and through Kensington, which he hated. It was a soulless place, a purgatory filled only with rich transients drifting pointlessly through Nicole Farhi and Red or Dead. He sped up Kensington Church Street towards Netting Hill and on through to Portobello Road.

It was a market day, the second in the week, designed to wrest money from tourists. Merchandise that had cost five pounds on Friday was now offered for ten. The air was thick with garish cagoules and backpacks and French and Italian. Fabian cussed quietly and inched through the throng. He ducked left down Elgin Crescent and then right, bearing down on the Bassett Road flat.

A gust of wind stained the air brown with leaves. Fabian swung into the street. The leaves boiled around him, stuck to his jacket. Pared-down trees lined the tarmac. Fabian dismounted while still in motion, walked towards Natasha’s flat.

He could hear her working. The faint thumping of Drum and Bass was audible from the end of the street. As he walked, wheeling his bike beside him, Fabian heard the sound of wings. Natasha’s house teemed with pigeons. Every protuberance and ledge was grey with plump, stirring bodies. A few were in the air, hovering nervously around the windows and gables, settling, dislodging their peers. They shifted and shat a little as Fabian stopped at the door directly below them.

Natasha’s rhythm was loud now, and Fabian could hear something unusual, a clear sound like pipes, a recorder or a flute, bursting with energy and exuberance, shadowing the bass. He stood still and listened. The quality of this sound was different from that of samples, and it was not trapped in any loops. Fabian suspected it was being played live. And by something of a virtuoso.

He rang the bell. The electronic boom of the bass stopped cold. The flute faltered on for a second or two. As silence fell, the company of pigeons rose en masse into the air with the abruptness of panic, circled once like a school of fish and disappeared into the north. Fabian heard footsteps on the stairs.

Natasha opened the door to him and smiled.

‘Alright, Fabe,’ she said, reaching up to touch her clenched right fist to his. He did so, at the same time bending down to put an arm around her and kiss her cheek. She responded, though her surprise was evident.
