One

Jane stood up and there was a responsive scratching noise. Mice, he thought. Or rats. Probably as spooked as him to find something breathing in the neighbourhood. He climbed the steps back into the pub and felt his way in the dark to the foot of the stairs leading up to the living quarters. There was a bathroom here. He tried the taps. Cold water sputtered and gushed into the basin. He peeled off his clothes and the bicycle mask and, holding his breath, splashed his face, feeling the growth of a week's worth of stubble. He towelled himself dry and replaced the mask. He moved through to a bedroom and opened a wardrobe, grabbed a handful of shirts and tried one on. Too large, but at least it was clean. It made him feel happier. He stole some jeans and a belt and pulled on his own boots. A long leather coat and leather gloves. There was a mound on the bed; he left it undisturbed. On a dressing table was a tea light in a red glass container. He lit it with a wax-coated match from the First Aid box. He avoided the bedroom door dotted with Spider-Man stickers and drew his shivering shadow along the corridor to the living room.

The living room was large; a dining table and an upright piano dominated one half. A fruit bowl contained mouldering shapes; their smell was cloying, dusty almost. A woman in black underwear was reclining on the sofa, a magazine opened on the floor beside her. A mug. A bar of chocolate. She glittered at him, her flesh pitted with shards of glass from an exploded window. He went to it and looked out at the silent village. Lightning pulsed in the clouds like something trapped, desperate to be set free. It afforded him views of desolation. Cars turned over in the road, windshields spidered with cracks, tyres gone. Bodies lay in the street. A house burned: restive orange eyes shivering in blistered sockets. Behind him, a page of the magazine turned. He imagined the woman stroking the ball of her thumb across the death-dry edge of her swollen tongue. He removed the mask and vomited hard. He spat and choked against the fire in his throat and nostrils, then rinsed his mouth with water from a bottle. He trudged downstairs and pushed his way out into the street. A bicycle could wait. He didn't want to stumble upon any more nasty little surprises in these homes. Get pounding. Put some miles under you.

Jane was grateful of the dark as he made his way to the edge of the village and onto the dual carriageway. Suggestions and shapes and murmurs remained so. The sea was an urgent incessant booming to his left, restless beneath a sky that, even at night, roiled with sombre colours, a melancholy oil painting failing to dry.

The A1 would take him all the way to London. The thought of a ribbon of tarmac connecting this shattered community with his son's feet quickened his blood. He imagined his boy sitting on the doorstep of the flat in Sevington Street, with Walter, grubby and matted, next to him. The big smile when he saw his dad. The leap into his arms. His little boy, so light, as he swung him up for a kiss. The astonishing colour of his eyes. Baize-green with an outer rim of cobalt. Freckles and milk teeth. He could feel his warmth, could smell the magic of his hair, his scalp.

Jane suddenly, reflexively, shouted his son's name. He realised he was running, sprinting, as if he might cover the hundreds of miles between here and Maida Vale before dawn. He wanted his boy so badly that he thought his heart would clench itself into a knot. Tears drizzled across his vision; he had to stop. He dropped to his knees and cried so violently that it felt as though he had pulled a muscle in his chest. He was nodding. Cars and lorries and coaches threw freakish shapes across the lanes for miles in either direction. He wished he'd been caught in this. He wished he had never left his family. He cursed the moment he had signed up for diving lessons and applied for a job on the rigs. He wished he had been infertile and had never met Cherry. He wished for utter oblivion.

'I know,' he said. 'I know.'

He was fooling himself. This was no isolated event. The whole country had been hit by this. Depth, he thought. Cherry might have taken their son on the Tube. He might be safe. He must be safe.
