One

tears.

He sat up. His breath came in plumes. The climate was like that of a desert. Hot days. Frozen nights. Thin plaques of ice matted the canvas. He broke a piece off and sucked it. A taste of metal and chemicals. He spat. He wondered if dreams of Stanley had wakened him, or something else. The others were breathing steadily in the tent. He gripped the rifle stock loosely, glad of the weapon, but wary too, worried that it might inspire violence in others. He gazed out over the rooftops and countryside, the swollen, haphazard road. He had suggested finding a big house to stay in, or a hotel, but Aidan had begged them not to, preferring the tent.

'I don't want to see anybody,' he explained. 'I don't like how their faces look soft. Like they're asleep but they're not.'

It was too dark to see anything beyond the shapes of battered houses and factories, broken fingers of mills, the great shoulders of hills muscling up against the town. Again, he wasn't sure where they were. Somewhere between north and south, he told Aidan, and Aidan had been satisfied with that.

There was a distant thrum, a brief vibration. Jane thought he felt something in his feet, but couldn't be sure. The horizon they had left behind contained a burnt orange smear. His mouth went dry at the thought of some power station having finally reached tipping point and gone into meltdown. It was inevitable. Maybe life on Earth from now on would be dictated by whichever way the wind was blowing.

He moved away from the tents and leant back against the badly crumpled bonnet of a car. The engine block had rocketed into the driver's zone, lifting the top of the man and depositing him in the back seat. Oblivion. Out like a light.

The idea of death had caused Jane many moments of panic as a younger man. Newspaper articles about random attacks: samurai swords in London churches, knives on Manchester buses, guns in Liverpool nightclubs. People set on fire. People tortured and gut-shot. Left for dead. But death didn't go on. Your nerves were incinerated beyond use by fire; your lungs filled with water. The struggle to survive was out of your hands. You were insensate before the end. Death came and calmed you down. And it could only happen once. He was no longer scared of death. He didn't feel he had the right to be, not after what had happened to Stopper and the others. But he was scared for Stanley. He wanted to be able to assuage his son's fears, hold his hand, show him there was nothing to be frightened of beneath the bed or in the wardrobe. Because Dad was here and everything would be all right.

He thought he sensed movement a way back off the road. Shadows congealing, dispersing. But it could just be the colour of the night, writhing in his eyes.

Something came sailing past him, riding high on the wind. A piece of clothing, perhaps. A plastic bag or the remnant of a flag. 'No standards left,' he said, and coughed a bitter chuckle. An ache was building around his teeth, an itchiness. His gums bled whenever he brushed his teeth. They bled when he bit into food. He wondered if it might be gingivitis. A friend of his mother's had lost all her teeth to gingivitis in her twenties. He half-wished Becky was a dentist instead of a radiologist.

He was tired, his feet, back and neck ached, but sleep played games with him. They were averaging, he guessed, between ten and twelve miles a day. Good going, with such a small boy in tow. Jane suspected his exhaustion was down to pushing Aidan in the wheelbarrow, but there was also the rain to contend with, and the diminishing food supplies. Some days he went without so that Aidan and Becky did not. While they slept he went hunting for cans, but it was alarming to discover that there were few to be found. Already the stockpiles had been rifled. There were survivors in their houses – maybe half a dozen so far – who said nothing as he approached, but showed him the grin of something sharp in their hands. They would not talk to him. Once he had been shot at.

He found a jar of pickled red cabbage in an end-of-terrace hovel taken over by rats. A skeleton sat in a squirming armchair, a china cup and saucer at its feet. There was a tin of bamboo shoots in a flat where someone seemed to have melted into the floorboards and left only his clothes behind. He had thought, Fuck bamboo shoots, you might as well can rabbit tods. And then he'd knifed the lid back and eaten it all there and then. It had been delicious. The supermarkets had become ghost buildings. Everything taken apart from DVDs, household electrical items, barbecues. Where were all these people? Where were all the survivors? Was everyone on the A1 ahead of him?

He wondered about his leisurely pursuers. He wondered if they were pursuing him at all. Maybe they were stripping provisions from his way ahead, pushing him towards some kind of test. He thought of the meat in the bowl. He thought of Becky and Aidan. God. The way your mind worked when you were up against it. All that trickle-down shit. A confrontation was ahead, he thought, one way or the other. Before they made it to London, perhaps. Or once they were ensconced there. He wondered what that meant, the moment it occurred to him. Just because he had lived there before didn't mean he had to stay there now. He would find Stanley and Cherry and they would leave, try to make it across the Channel to France, somewhere where this fury had not touched, if there was anywhere like that left. He wasn't going to spend the rest of his life fighting over crumbs in Kentish Town larders and carrying the gun with him every time he took his boy to play in Coram's Fields.

His throat ached for cold beer. The whisky was too strong to drink greedily, and he could do a good session, he felt he deserved a night on the lash. Thirsty, he went back to the tent and drank from the bladder. Becky and Aidan were in the same positions he'd left them. He heard the scrabble of pebbles loosed from a bank of earth, the hush of dead vegetation kicked to dust as bodies hurried by it.

'Show yourselves,' he whispered. 'Talk to me.'

He fell asleep sitting upright, in an awkward position. Aidan nudged him awake as he hopped from foot to foot, trying to unzip the tent's entrance so he could go out for a piss. Jane's neck flared with pain. He stood up, rubbing at it. Cold had seeped into his bones.

'Where's Becky?' He blinked, looking out at the pale morning, finding it hard to believe that he had been asleep for any length of time; the darkness, and the sounds, and his uneasy thoughts seemed to have been the product of only a few seconds previously.

'She said she was going to try to find us some breakfast. She said she was sick to the back teeth of dried apricots. She said don't worry. She said she was going to do things and buy a book.'

'By the book,' Jane corrected. 'So much for democracy.'

'What?'

'Never mind.'

Aidan helped him take down the tent and pack it in the rucksacks. They sat together on the rucksacks, feeling the temperature climb, waiting. They talked about books. Aidan liked Where the Wild Things Are.

'Do you still like it?' Jane asked, but Aidan didn't understand what he meant.

The thought of books had stayed with him. He supposed there would be no more. Not for a long time, at least. He thought of all the books he had read over his lifetime, a great deal of them in those prison cells of hyperbaric chambers where there'd been little else to do. Were they still important? Maybe yes. Maybe more so than ever. Aidan had not been read a bedtime story since they'd found him. That wasn't good enough. It was time to remember the stories Jane had been told as a child, or make up some new ones. It had been a while – he remembered singing silly, off-the-cuff songs to lull Stanley to sleep – but it was in him; it was in everyone, like the skill to make fire, or love.

Becky came back empty-handed. He was harder on her than he should have been, perhaps because of that.

'I just looked in a corner shop,' she said. 'I waited a long time to make sure there was nobody inside.'

'But that's not the problem, is it?' he asked. 'It's people on the outside, watching you, waiting for you to make your move.'

'Well, I'm here aren't I?' she snapped.

'Have a dried apricot.'

They walked most of the day in silence.

'How many minutes until we get to London?' Aidan asked.

'I don't know,' Jane said.

'Ten?'

'A bit more than that.' But he wasn't really listening any more. Up ahead, maybe a mile away, there was a strange glinting on the road, as if someone were sending messages by reflecting light off glass.

'What's that?' Becky asked. They had all stopped.
