Back from Canada, as if on stretched elastic, had immediately snapped an unsuspected nephew, brandishing a will in his favour and demanding his rights. He did not, he said forth-rightly, want to sell half his inheritance to a one-handed ex-jockey, especially at the price agreed. He himself would be taking over and breathing new life into the whole works. He himself would be setting it all up in new modern offices, not the old crummy bomb-damaged joint in the Cromwell Road, and anyone who didn't like the transfer could vote with his feet.

Most of the old bunch had stayed on into the new order, but Chico had had a blazing row with the nephew and opted for the dole. Without much trouble he had then found the part-time job teaching judo, and the first time I'd asked for his help he'd joined up with enthusiasm. Since then I myself seemed to have become the most regularly employed investigator working in racing, and if Radnor's nephew didn't like it (and he was reputed to be furious) it was just too bad.

Chico bounced out through the swinging glass doors of the school with the lights behind him making a halo round his curly hair. Any resemblance to sainthood stopped precisely there, since the person under the curls was in no way long-suffering, god-fearing or chaste.

He slid into the car, gave me a wide grin, and said, 'There's a pub round the corner with a great set of bristols.'

Resignedly I pulled into the pub's car park, and followed him into the bar. The girl dispensing drinks was, as he'd said, nicely endowed, and moreover she greeted Chico with telling warmth. I listened to the flirting chit chat and paid for the drinks.

We sat on a bench by the wall, and Chico approached his pint with the thirst brought on by too much healthy exercise.

'Ah,' he said, putting down the tankard temporarily. 'That's better.' He eyed my glass. 'Is that straight orange juice?'

I nodded. 'Been drinking on and off all day.'

'Don't know how you bear it, all that high life and luxury.'

'Easily.'

'Yeah.' He finished the pint, went back for a refill and another close encounter with the girl, and finally retracked to the bench. 'Where do I go then, Sid? And what do I do?'

' Newmarket. Spot of pub-crawling.'

'Can't be bad.'

'You're looking for a head lad called Paddy Young. He's George Caspar's head lad. Find out where he drinks, and sort of drift into conversation.'

'Right.'

'We want to know the present whereabouts of three horses which used to be in his yard.'

'We do?'

'He shouldn't have any reason for not telling you, or at least, I don't think so.'

Chico eyed me. 'Why don't you ask George Caspar, right out? Be simpler, wouldn't it?'

'At the moment we don't want George Caspar to know we're asking questions about his horses.'

'Like that, is it?'

'I don't know, really.' I sighed. 'Anyway, the three horses are Bethesda, Gleaner, and Zingaloo.'

'O. K. I'll go up there tomorrow. Shouldn't be too difficult. You want me to ring you?'

'Soon as you can.'

He glanced at me sideways. 'What did the limb man say?'

'Hallo, Sid, nice to see you.'

He made a resigned noise with his mouth. 'Might as well ask questions of a brick wall.'

'He said the ship wasn't leaking and the voyage could go on.'

'Better than nothing.'

'As you say.'

I went to Aynsford, as Charles had known I would, driving down on Saturday afternoon and feeling the apprehensive gloom deepen with every mile. For distraction I concentrated on Chico 's news from Newmarket, telephoned through at lunchtime.

'I found him,' he said. 'He's a much-married man who has to take his pay packet home like a good boy on Friday evenings, but he sneaked out for a quick jar just now. The pub's nearly next door to the yard; very handy. Anyway, if you can understand what he says, and he's so Irish it's like talking to a foreigner, what it boils down to is that all three of those horses have gone to stud.'

'Did he know where?'

'Sure. Bethesda went to some place called Garvey's in Gloucestershire, and the other two are at a place just outside Newmarket, which Paddy Young called Traces, or at least I think that's what he said, although as I told you, he chews his words up something horrible.'

' Thrace,' I said. 'Henry Thrace.'

'Yeah? Well, maybe you can make sense of some other things he said, which were that Gleaner had a tritus and Zingaloo had the virus and Bruttersmit gave them both the turns down as quick as Concorde.'

'Gleaner had a what?'

'Tritus.'

I tried turning 'Gleaner had a tritus' into an Irish accent in my head and came up with Gleaner had arthritis, which sounded a lot more likely. I said to Chico, '… and Brothersmith gave them the thumbs down…'

'Yeah,' he said. 'You got it.'

'Where are you 'phoning from?'

'Box in the street.' 'There's a bit of boozing time left,' I said. 'Would you see if you can find out if this Brothersmith is George Caspar's vet, and if so, look him up in the 'phone book and bring back his address and number.'

'O. K. Anything else?'

'No.' I paused. ' Chico, did Paddy Young give you any impression that there was anything odd in these three horses going wrong?'

'Can't say he did. He didn't seem to care much, one way or the other. I just asked him casual like where they'd gone, and he told me, and threw in the rest for good measure. Philosophical, you could say he was.'

'Right, then,' I said. 'Thanks.'

We disconnected, but he rang again an hour later to tell me that Brothersmith was indeed George Caspar's vet, and to give me his address.

'If that's all, then, Sid, there's a train leaving in half an hour, and I've a nice little dolly waiting for me round Wembley way who'll have her Saturday night ruined if I don't get back.'

The more I thought about Chico 's report and Bobby Unwin's comments the less I believed in Rosemary's suspicions; but I'd promised her I would try, and try I still would, for a little while longer. For as long as it took me, anyway, to check up on Bethesda, Zingaloo and Gleaner, and talk to Brothersmith the vet.

Aynsford still looked its mellow stone self, but the daffodil-studded tranquillity applied to the exterior only. I stopped the car gently in front of the house and sat there wishing I didn't have to go in.

Charles, as if sensing that even then I might back off and drive away, came purposefully out of his front door and strode across the gravel. Watching for me, I thought. Waiting. Wanting me to come.

'Sid,' he said, opening my door and stooping down to smile. 'I knew you would.'

'You hoped,' I said. I climbed out onto my feet.

'All right.' The smile stayed in his eyes. 'Hoped. But I know you.'

I looked up at the front of the house, seeing only blank windows reflecting the greyish sky.

'Is she here?' I said.

He nodded. I turned away, went round to the back of the car, and lugged out my suitcase.

'Come on, then,' I said. 'Let's get it over.'

'She's upset,' he said, walking beside me. 'She needs your understanding.'

I glanced at him and said 'Mm.' We finished the short journey in silence, and went through the door.

Jenny was standing there, in the hall.

I had never got used to the pang of seeing her on the rare occasions we had met since she left. I saw her as I had when I first loved her, a girl not of great classical beauty, but very pretty, with brown curling hair and a neat figure, and a way of holding her head high, like a bird on the alert. The old curving smile and the warmth in her eyes were gone, but I tended to expect them, with hopeless nostalgia.

'So you came,' she said. 'I said you wouldn't.'

I put down the suitcase and took the usual deep breath. 'Charles wanted me to,' I said. I walked the steps towards her, and as always, we gave each other a brief kiss on the cheek. We had maintained the habit as the outward and public mark of a civilised divorce; but privately, I often thought, it was more like the ritual salute before a duel.
