He had told Amy none of this but would have happily confided had she shown the least interest. But she asked no questions about his past life and told him nothing about hers. Her voice, her body, her smell were as familiar to him as his own, but essentially he knew no more about her now than when she had arrived. She refused to collect any welfare benefits, saying that she wasn't going to have DHSS snoopers visiting the caravan to see if she and Neil were sleeping together. He sympathized. He didn't want them either, but he felt that for Timmy's sake she should take what was on offer. He had given her no money but he did feed both of them, and this was difficult enough on his grant. No one visited her and no one telephoned. Occasionally she would receive a postcard, coloured views usually of London with nondescript, meaningless messages, but as far as he knew she never replied.

They had so little in common. She helped spasmodically with PANUP but he was never sure how far she was actually committed. And he knew that she found his pacifism stupid. He could recall a conversation only this morning.

'Look, if I live next door to an enemy and he has a knife, a gun and a machine gun and I've got the same, I'm not going to chuck mine before he chucks his. I'll say, OK, let the knife go, then the gun maybe, then the machine gun. Him and me at the same time. Why should I throw mine away and leave him with his?'

'But one of you has to make a start, Amy. There has to be a beginning of trust. Whether it's people or nations, we have to find the faith to open our hearts and hands and say, "Look, I've nothing. I've only my humanity. We inhabit the same planet. The world is full of pain but we needn't add to it. There has to be an end of fear."'

She had said obstinately: 'I don't see why he should chuck his weapons once he knows I've got nothing.'

'Why should he keep them? He's got nothing to fear from you any more.'

'He'd keep them because he liked the feeling of having them and because he might like to use them some day. He'd like the power and he'd like knowing he had me where he wanted me. Honestly, Neil, you're so naive sometimes. That's how people are.'

'But we can't argue like that any more, Amy. We aren't talking about knives and guns and machine guns. We're talking about weapons neither of us could use without destroying ourselves and probably our whole planet. But it's good of you to help with PANUP when you don't sympathize.'

She had said: 'PANUP's different. And I sympathize all right. I just think that you're wasting your time writing letters, making speeches, sending out all those pamphlets. It won't do any good. You've got to fight people their way.'

'But it's done good already. All over the world ordinary people are marching, demonstrating, making their voices heard, letting the people in power know that what they want is a peaceful world for themselves and their children. Ordinary people like you.'

And then she had almost shouted at him: 'I'm not ordinary! Don't you call me ordinary! If there are ordinary people, I'm not one of them.'

'I'm sorry, Amy. I didn't mean it like that.'

'Then don't say it.'

The only cause they had in common was a refusal to eat meat. Soon after she arrived at the caravan he had said: 'I'm vegetarian but I don't expect you to be, or Timmy.' He had wondered as he spoke whether Timmy was old enough to eat meat. He had added: 'You can buy a chop occasionally in Norwich if you feel like it.'

'What you have is all right by me. Animals don't eat me, and I don't eat them.'

'And Timmy?'

'Timmy has what I give him. He's not fussy.'

Nor was he. Neil couldn't imagine a more accommodating child nor, for most of the time, a more contented one. He had found the second-hand playpen advertised on a newsagent's board in Norwich and had brought it back on the top of the van. In it Timmy would crawl for hours or pull himself up and stand precariously balancing, his napkin invariably falling about his knees. When thwarted he would rage, shutting his eyes tight, opening his mouth and holding his breath before letting out a bellow of such terrifying power that Neil half expected the whole of Lydsett to come running to see which of them was tormenting the child. Amy never smacked him but would jerk him on to her hip and dump him on her bed saying: 'Bloody awful noise.'

'Shouldn't you stay with him? Holding his breath like that, he could kill himself.'

'You daft? He won't kill himself. They never do.'

And he knew now that he wanted her, wanted her when it was obvious that she didn't want him and would never again risk rejection. On the second night at the caravan she had slid back the partition between his bed and hers and had walked quietly up to his bed and had stood gravely looking down at him. She had been completely naked. He had said: 'Look, Amy, you don't have to pay me.'

'I never pay for anything, at least not like that. But have it your own way.' After a pause she had said: 'You gay or something?'

'No, it's just that I don't like casual affairs.'

'You mean you don't like them, or you don't think you ought to have them?'

'I suppose I mean that I don't think I ought to have them.'

'You religious, then?'

'No, I'm not religious, not in the ordinary way. It's just that I think sex is too important to be casual about. You see, if we slept together and I – if I disappointed you – we might quarrel and then you'd walk out. You'd feel that you had to. You'd leave, you and Timmy.'

'So what, I walk out.'

'I wouldn't want you to do that, not because of anything I'd done.'

'Or hadn't done. OK, I expect you're right.' Another pause, and then she had added: 'You'd mind then, if I walked out?'

'Yes,' he said, 'I'd mind.'

She had turned away. 'I always do walk out in the end. No one has ever minded before.'

It was the only sexual advance she had ever made to him and he knew it would be the last. Now they slept with Timmy's cot wedged between the partition and his bed. Sometimes in the night, wakeful because the child had stirred, he would put out his hands and clasp the bars and long to shake this frail barrier that symbolized the unbridgeable gulf between them. She lay there, sleek and curved as a fish or a gull, so close that he could hear the rise and fall of her breath faintly echoing the suspiration of the sea. His body ached for her and he would press his face into the lumpy pillow groaning with the hopelessness of his need. What could she possibly see in him to make her want him, except, as on that one night, out of gratitude, pity, curiosity or boredom? He hated his body, the scrawny legs on which the kneecaps protruded like deformities, the small blinking eyes too closely set, the sparse beard which couldn't disguise the weakness of the mouth and chin. Sometimes, too, he was tormented by jealousy. Without proof, he had convinced himself that there was someone else. She would say that she wanted to walk alone on the headland. And he would watch her go with the certainty that she was meeting a lover. And when she returned he would imagine that he could see the glow of the skin, the satisfied smile of remembered happiness, could almost smell that she had been making love.

He had already heard from the university that his research grant would not be extended. The decision wasn't surprising; he had been warned to expect it. He had been saving as much as possible from the grant in the hope of amassing a small sum which would tide him over until he could find a local job. It hardly mattered what. Anything that would pay enough to live and allow him to remain on the headland to carry on the campaign. In theory he supposed he could organize PANUP from anywhere in the UK, but he knew that it was irrevocably bound to Larksoken headland, to the caravan, to that concrete mass five miles to the north which had power, apparently, to dominate his will as it did his imagination. He had already put out feelers with local employers but they hadn't been too keen on employing a well-known agitator; even those who seemed sympathetic to the anti-nuclear cause didn't actually have work on offer. Perhaps they feared that too many of his energies would be diverted to the campaign. And his small capital was draining away with the extra expense of Amy, Timmy and even the cats. And now there was the threat of this libel action, less of a threat than a certainty.
