The marksman's special skill was drifting towards sport, as archery had, as swordplay had, as throwing the javelin and the hammer had; the commonplace weapon of one age becoming the Olympic medal of the next.

I didn't shoot very well on that particular afternoon and found little appetite afterwards for the camaraderie in the clubhouse. The image of Peter stumbling over the side of his boat on fire and dying made too many things seem irrelevant. I was pledged to shoot in the Queen's Prize in July and in a competition in Canada in August, and I reflected driving home that if I didn't put in a little more practice I would disgrace myself.

The trips overseas came up at fairly regular intervals, and because of the difficulties involved in transporting guns from one country to another, I had had built my own design of carrying case. About four feet long and externally looking like an ordinary extra-large suitcase, it was internally lined with aluminium and divided into padded shock-absorbing compartments. It held everything I needed for competitions, not only three rifles but all the other paraphernalia; score-book, ear-defenders, telescope, rifle sling, shooting glove, rifle oil, cleaning rod, batman jag, roll of flannelette patches, cleaning brush, wool mop for oiling the barrel, ammunition, thick jersey for warmth, two thin olive-green protective boiler suits and a supporting canvas and leather jacket. Unlike many people, I usually carried the guns fully assembled and ready to go, legacy of having missed my turn once through traffic hold-ups, a firearm still in pieces and fingers trembling with haste. I was not actually supposed to leave them with the bolt in place, but I often did. Only when the special gun suitcase went onto aeroplanes did I strictly conform to regulations, and then it was bonded and sealed and hedged about with red tape galore; and perhaps also because it didn't look like what it was, I'd never lost it.

Sarah, who had been enthusiastic at the beginning and had gone with me often to Bisley, had in time got tired of the bang bang bang, as most wives did. She had tired also of my spending so much time and money and had been only partly mollified by the Games. All the jobs I applied for, she had pointed out crossly, let us live south of London, convenient for the ranges. 'But if I could ski,' I'd said, 'it would be silly to move to the tropics.'

She had a point, though. Shooting wasn't cheap, and I wouldn't have been able to do as much as I did without support from indirect sponsors. The sponsors expected in return that I would not only go to the international competitions, but go to them practised and fit: conditions that until very recently I'd been happy to fulfil. I was getting old, I thought. I would be thirty-four in three months.

I drove home without haste and let myself into the quiet house which was no longer vibrant with silent tensions. Dumped my case on the coffee table in the sitting-room with no one to suggest I take it straight upstairs. Unclipped the lock and thought of the pleasant change of being able to go through the cleaning and oiling routine in front of the television without tight-lipped disapproval. Decided to postpone the clean-up until I'd chosen what to have for supper and poured out a reviving scotch.

Chose a frozen pizza. Poured the scotch.

The front doorbell rang at that point and I went to answer it. Two men, olive skinned, dark haired, stood on the doorstep: and one of them held a pistol.

I looked at it with a sort of delayed reaction, not registering at once because I'd been looking at peaceful firearms all day. It took me at least a whole second to realise that this one was pointing at my midriff in a thoroughly unfriendly fashion. A Walther. 22, I thought: as if it mattered.

My mouth, I dare say, opened and shut. It wasn't what one expected in a moderately crime-free suburb.

'Back,' he said.

'What do you want?'

'Get inside.' He prodded towards me with the long silencer attached to the automatic and because I certainly respected the blowing-away power of hand guns, I did as he said. He and his friend advanced through the front door and closed it behind them.

'Raise your hands,' said the gunman.

I did so.

He glanced towards the open door of the sitting-room and jerked his head towards it.

'Go in there.'

I went slowly, and stopped, and turned, and said again, 'What do you want?'

'Wait,' he said. He glanced at his companion and jerked his head again, this time at the windows. The companion switched on the lights and then went across and closed the curtains. It was not yet dark outside. A shaft of evening sunshine pierced through where the curtains met.

I thought: why aren't I desperately afraid? They looked so purposeful, so intent. Yet I still thought they had made some weird sort of mistake and might depart if nicely spoken to.

They seemed younger than myself, though it was difficult to be sure. Italian, perhaps, from the south. They had the long straight nose, the narrow jaw, the black-brown eyes. The sort of face which went fat with age, grew a moustache and became a godfather.

That last thought shot through my brain from nowhere and seemed as nonsensical as a pistol.

'What do you want?' I said again.

'Three computer tapes.'

My mouth no doubt went again through the fish routine. I listened to the utterly English sloppy accent and thought that it couldn't have less matched the body it came from.

'What… what computer tapes?'I said, putting on bewilderment.

'Stop messing. We know you've got them. Your wife said so.'

Jesus, I thought. The bewilderment this time needed no acting.

He jerked the gun a fraction. 'Get them,' he said. His eyes were cold. His manner showed he despised me.

I said with a suddenly dry mouth, 'I can't think why my wife said… why she thought…'

'Stop wasting time,' he said sharply.

'But-'

'The King and I, and West Side Story,'' he said impatiently, 'and Okla-fucking-homa.'

'I haven't got them.'

'Then that's too bad, buddy boy,' he said, and there was in an instant in him an extra dimension of menace. Before, he had been fooling along in second gear, believing no doubt that a gun was enough. But now I uncomfortably perceived that I was not dealing with someone reasonable and safe. If these were the two who had visited Peter, I understood what he had meant by frightening. There was a volatile quality, an absence of normal inhibition, a powerful impression of recklessness. The brakes-off syndrome which no legal deterrents deterred. I'd sensed it occasionally in boys I'd taught, but never before at such magnitude.

'You've got something you've no right to,' he said. 'And you'll give it to us.'

He moved the muzzle of the gun an inch or two sideways and squeezed the trigger. I heard the bullet zing past close to my ear. There was a crash of glass breaking behind me. One of Sarah's mementos of Venice, much cherished.

'That was a vase,' he said. 'Your television's next. After that, you. Ankles and such. Give you a limp for life. Those tapes aren't worth it.'

He was right. The trouble was that I doubted if he would believe that I really hadn't got them.

He began to swing the gun round to the television.

'OK.'I said.

He sneered slightly. 'Get them, then.'

With my capitulation he relaxed complacently and so did his obedient and unspeaking assistant, who was standing a pace to his rear. I walked the few steps to the coffee table and lowered my hands from the raised position.

'They're in the suitcase,' I said.

'Get them out.'

I lifted the lid of the suitcase a little and pulled out the jersey, dropping it on the floor.

'Hurry up,' he said.

He wasn't in the least prepared to be faced with a rifle; not in that room, in that neighbourhood, in the hands of the man he took me for.
