One

Bright blue eyes. Hair white. Hawkish. Sunken. He said maybe two dozen words to me before he died. I was thirteen by then. Miserable fucker, all things considered.

'I'd started to get into fishing. I was only six or seven. But I could set up a rig. I knew about baiting a swim. I knew the difference between a roach and a rudd. We didn't catch a thing. Dad and Grandad both fell asleep. I went for a walk, took my rod with me. Over a stile. Through a field to some trees. There was a gravel pit beneath them. I caught roach after roach, or maybe it was the same one. And then I realised I was being watched.

'It was like a window of stained glass had shattered into a thousand pieces and they were all hanging in the air behind me. It was a little scary, but I knew they couldn't sting me, they weren't like wasps. They didn't come near, as if they were attracted to you. They hung back. Hundreds of them. Maybe it was birthday for dragonflies, this particular day. You look at a dragonfly for a while, then everything else seems so dull afterwards.

'I wouldn't know how to tell him. I wouldn't know how to describe it to him. How do you describe a dragonfly to someone who hasn't seen one? You might as well be blind.'

Jane slept again, or fell unconscious. When he came to, he felt stiff, immobile. For terrifying seconds he thought he had been captured by his pursuers, ravened from the inside and left nailed to a post for the birds of his nightmares to tear strips from. But he was only lying on a blanket, his arms above his head – the way Stanley had slept as a baby – his midriff bandaged tightly, professionally. His head felt warm, treacly, his veins felt warm. He thought that if he closed his eyes he could visualise his entire circulatory system, map it in his head, every junction and branch and bend.

Gradually, the real world began to impinge. The wind skirled above their heads, cheated out of them by the high tops of lorries on either side. Their canvas skins thumped and fluttered and creaked. The woman and the child, the dead child in the shopping trolley, were gone.

Becky must have manhandled Jane into the barrow, got him across that macerated field and onto the road again. She was sitting by Aidan, stroking his hair, leaning over one arm, a blade of hair hiding her eyes from him. She looked spent.

Perhaps she sensed Jane's inspection, or heard the slightest shift of his arms as he repositioned himself; she looked up. Her eyes were red-rimmed, her skin sallow.

Aidan said, 'I want to go home.'

Jane resisted the urge: You are home.

'We've nothing to eat,' Becky said. 'And it's weird. It's not that I feel tired, I mean I do, I'm knackered. But it's just . . . there's nothing in the tank. I'm depressed just at the thought of having to lift that pack onto my shoulders again. And it's not as if it's all that heavy.'

Jane sat up. He felt light-headed, but otherwise OK. He felt guilty that he had rested while the others had not. But he would pay them back. There was no danger of that not happening. The pain drew his eyes closed, but he didn't cry out. The bandage seemed to muffle it somehow, that and whatever Becky had slipped into his arm while he was out of it.

'Lorazepam,' she admitted when he asked her. 'Just to take the edge off. You deserved it, after what happened.' 'How much have you got left?'

'A couple of ampoules. For special occasions.'

'It's good. It's very good.'

He felt honey-coated, bubble-wrapped. He looked around him at the cars and lorries, some super-magnified child's game in the moment of its abandonment. His head beat with the lack of sugar in his blood. But he tried to think. He'd seen something that teased him, like a scab not quite ripe for picking. He looked at Becky and Aidan. He looked at the lorries. The cars. A red car, maybe sixty yards down the road. Dented, windscreen cracked, layered with dust, but it had a sheen about it, an immaculateness that was missing in the others. Lady driver, he thought. Careful owner, full service history. He stood up, shakily.

'Richard,' Becky said, in that voice, that nurse's voice she had down pat.

'It's OK,' he said. He wondered if he'd lost much blood. But the wound had only scored his chest. No major blood vessels there. Perhaps just a fine fighting scar on his ribs to impress any bonehunters of the future.

There was a shrivelled figure in the driver's seat, ageless, sexless, dwarfed by heat. There was a pair of softened crutches, bowing over a singed passenger seat. Something plastic on the dashboard wrinkled to a coin- sized disc. Disabled badge?

He checked the odometer. Less than 15,000, although the car was over three years old.

Where were you going?

Jane went round to the back of the car and tried the boot. Locked. He lifted the back seat but there was no jack to be found. He replaced the seat and rubbed his face.

Where had you been?

Between the seats was an armrest, folded into a well. He put his finger through the loop and pulled it into position. In the well was a plastic tab. He opened it; a little door to the boot, handy access to bits and bobs to save you from stopping mid-journey.

Just a little runaround. Something to get me down to the shops.

Cardboard boxes. Maybe half a dozen of them. He called to Aidan. 'Come and help. I need a super-strong boy with little hands.'

Two of the boxes were filled with perishables. Vacuumpacks of ham, beef, chicken. Yogurt. Butter. Milk. Bread. Ice cream. The stink of it made Jane's eyes water. 'Ripe Christ,' he said. 'That stuff is ready to make an evolutionary leap.'

Aidan said, 'Ice cream,' as if he had never heard the words before. 'I like ice cream.' He began to cry.

The other bags contained tins. Lots of them: beans, spaghetti hoops, red salmon, Toast Toppers, pineapples, tomato soup, Coca-Cola, 7-Up, Stella Artois. There was a box of Rice Krispies. A pack of sugar. Energy bars. Jane stopped Aidan's tears with a can of strawberry-flavoured long-life milk.

'Nearly as good as ice cream, yes?' Jane asked him.

'Actually, yes,' Aidan said. 'Actually. Very refreshing.'

They ate until they felt stronger. The sponge of their muscles receded. The vignetting in their sight disappeared. They could breathe more deeply, more freely. Even breathing could become too much effort. A bad sign, if they needed one, Jane thought, replenishing their packs.

They walked on into early evening. It began to rain. They pitched camp. Jane slept so deeply that he could remember no dreams when he wakened, although his eyes were crusted and there were tracks through the glaze of blood on his cheek: he had been crying in the night. Almost as soon as they had packed up and were moving on they found a road sign that had been uprooted and was face down on the hard shoulder. Aidan helped him to lift it.

'My God,' Jane said. 'My God.'

LONDON 38

14. DESCENT

Aidan skipped across chevrons at a slip road. Becky walked a little way ahead of him, to his right. Jane brought up the rear, pushing the wheelbarrow. He was itching to get rid of it. There was no need any more. Their packs were full, the road was coming to an end. Within three days they would be in London.

He was hunched over the barrow, his breath coming in short, shallow scoops. Becky kept admonishing him, telling him to stand up straight and breathe normally, but the pain in his chest wouldn't allow it. One foot in front of the other. Twelve miles a day. Three days. He imagined Stanley standing at the balcony, watching out for him. He will be here, Mummy. He will.

Whenever he felt his mind bending towards dark things he rescued himself with thoughts of Stanley. In this way he believed he was confirming Stanley's survival and reminding himself what it meant to know order, to be human. He thought of taking his son to the fair in Hyde Park. Stanley must have been around three. Jane had been disgusted by the prices, but to see his son laughing to the point of losing control was worth ten times what he had paid. He had decided to let Stanley be in charge after that. They would otherwise have gone home and watched TV, but he didn't want to be locked inside with Cherry tutting and shaking her head all afternoon. They had walked –
