'Stop feeling guilty,' I said. 'Go on about the handicapping.'

After a while he was able to.

'He gave me pages and pages of stuff. Dozens of them. All handwritten in diabolical handwriting. He wanted it organised into programs that any fool could run on a computer.' He paused. 'You do know about computers.'

'More about microchips than programming, which isn't saying much.'

'The other way round from most people, though.'

'I guess so,' I said.

'Anyway, I did them. Quite a lot of them. It turned out they were all much the same sort of thing. They weren't really very difficult, once I'd got the hang of what the notes all meant. It was understanding those which was the worst. So, anyway, I did the programs and got paid in cash.' He stopped and moved restlessly in his seat, glum and frowning.

'So what is wrong?' I asked.

'Well, I said it would be best if I ran the programs a few times on the computer he was going to use, because so many computers are different from each other, and although he'd told me the make of computer he'd be using and I'd made allowances, you never can really tell you've got no bugs until you actually try things out on the actual type of machine. But he wouldn't let me. I said he wasn't being reasonable and he told me to mind my own business. So I just shrugged him off and thought if he wanted to be so stupid it was his own affair. And then these other two men turned up.'

'What other two men?'

'I don't know. They just sneered when I asked their names. They told me to hand over to them the programs I'd made on the horses. I said I had done. They said they were nothing to do with the person who'd paid for the job, but all the same I was to give them the programs.'

'And did you?'

'Well, yes – in a way.'

'But, Peter-' I said.

He interrupted, 'Yes, I know, but they were so bloody frightening. They came the day before yesterday – it seems years ago – in the evening. Donna had gone out for a walk. It was still light. About eight o'clock, I should think. She often goes for walks…'He trailed off again and I gave his glass a nudge with the bottle. 'What?' he said. 'Oh no, no more, thanks. Anyway, they came, and they were so arrogant, and they said I'd regret it if I didn't give them the programs. They said Donna was a pretty little missis, wasn't she, and they were sure I'd like her to stay that way.' He swallowed. 'I'd never have believed… I mean, that sort of thing doesn't happen…'

It appeared, however, that it had.

'Well,' he said, rallying, 'what I gave them was all that I had in the house, but it was really only first drafts, so to speak. Pretty rough. I'd written three or four trial programs out in long-hand, like I often do. I know a lot of people work on typewriters or even straight onto a computer, but I get on better with pencil and rubber, so what I gave them looked all right, especially if you didn't know the first thing about programming, which I should think they didn't, but not much of it would run as it stood. And I hadn't put the file names on anyway, or any REMS or anything, so even if they de-bugged the programs they wouldn't know what they referred to.'

Disentangling the facts from the jargon, it appeared that what he had done had been to deliver to possibly dangerous men a load of garbage, knowing full well what he was doing.

'I see,' I said slowly, 'what you meant by a mess.'

'I'd decided to take Donna away for a few days, just to be safe. I was going to tell her as a nice surprise when I got home from work yesterday, and then the police turned up in my office, and said she'd taken… taken… Oh Christ, how could she?'

I screwed the cap onto the bottle and I looked at my watch. 'It's getting on for midnight,' I said. 'We'd better go back.'

'I suppose so.'

I paused with my hand on the ignition key. 'Didn't you tell the police about your two unpleasant visitors?' I said.

'No, I didn't. I mean, how could I? They've been in and out of the house, and a policewoman too, but it was all about Donna. They wouldn't have listened, and anyway…'

'Anyway what?'

He shrugged uncomfortably. 'I got paid in cash. Quite a lot. I'm not going to declare it for tax. If I told the police… well, I'd more or less have to.'

'It might be better,' I said.

He shook his head. 'It would cost me a lot to tell the police, and what would I gain? They'd make a note of what I said and wait until Donna got bashed in the face before they did anything. I mean, they can't go around guarding everyone who's been vaguely threatened night and day, can they? And as for guarding Donna- well, they weren't very nice to her, you know. Really rotten, most of them were. They made cups of tea for each other and spoke over her head as if she was a lump of wood. You'd think she'd poked the baby's eyes out, the way they treated her.'

It didn't seem unreasonable to me that official sympathy had been mostly on the side of the baby's frantic mother, but I didn't say so.

'Perhaps it would be best, then,' I said, 'if you did take Donna away for a bit, straight after the hearing. Can you get leave?'

He nodded.

'But what she really needs is proper psychiatric care. Even a spell in a mental hospital.'

'No,' he said.

'They have a high success rate with mental illness nowadays. Modern drugs, and hormones, and all that.'

'But she's not-' He stopped.

The old taboos died hard. 'The brain is part of the body,' I said. 'It's not separate. And it goes wrong sometimes, just like anything else. Like the liver. Or the kidneys. You wouldn't hesitate if it was her kidneys.'

He shook his head, however, and I didn't press it. Everyone had to decide things for themselves. I started the car and wheeled us back to the house, and Peter said as we turned into the short concrete driveway that Donna was unusually happy on their boat, and he would take her away on that.

The weekend dragged on. I tried surreptitiously now and then to mark the inexorable exercise books, but the telephone rang more or less continuously and, as answering it seemed to be the domestic chore I was best fitted for, I slid into a routine of chat. Relatives, friends, press, officials, busybodies, cranks and stinkers, I talked with the lot.

Sarah cared for Donna with extreme tenderness and devotion and was rewarded with wan smiles at first and, gradually, low-toned speech. After that came hysterical tears, a brushing of hair, a tentative meal, a change of clothes, and a growth of invalid behaviour.

When Peter talked to Donna it was in a miserable mixture of love, guilt and reproach, and he found many an opportunity of escaping into the garden. On Sunday morning he went off in his car at pub-opening time and returned late for lunch, and on Sunday afternoon I said with private relief that I would now have to go back home ready for school on Monday.

I'm staying here,' Sarah said. 'Donna needs me. I'll ring my boss and explain. He owes me a week's leave anyway.'

Donna gave her the by now ultra-dependent smile she had developed over the past two days, and Peter nodded with eager agreement.

'OK,' I said slowly, 'but take care.'

'What of?'Sarah said.

I glanced at Peter, who was agitatedly shaking his head. All the same, it seemed sensible to take simple precautions.

'Don't let Donna go out alone,' I said.

Donna blushed furiously and Sarah was instantly angry, and I said helplessly, 'I didn't mean… I meant keep her safe… from people who might want to be spiteful to her.'

Sarah saw the sense in that and calmed down, and a short while later I was ready to leave.

I said goodbye to them in the house because there seemed to be always people in the street staring at the windows with avid eyes, and right at the last minute Peter thrust into my hand three cassettes for playing in the car if I should get bored on the way home. I glanced at them briefly: The King and I, Oklahoma, and West Side Story. Hardly the latest rave, but I thanked him anyway, kissed Sarah for appearances, kissed Donna ditto, and with a regrettable lightening of spirits took myself off.
