‘How long have you known the colonel, Mr Stein? If you don’t mind my asking.’

‘I first met the colonel in 1943,’ said Stein. ‘He was only a lieutenant in those days but he was the toughest son of a bitch in the regiment, I tell you. He took the regimental boxing championship in middleweight three times in a row. For a middleweight he was heavy, see. He was one hundred and fifty pounds and having trouble staying under the prescribed one hundred sixty, on account of all the drinking he was doing in the officers’ club. Yes, quite a man.’

‘We never see any of his family over here,’ said the driver. He moved in his seat to see Charles Stein in the mirror and hesitated before saying, ‘It’s a shame the colonel never got married. He loves children, you know. He should have had a family of his own.’

‘The battalion was his family,’ said Stein. ‘He loved those men, Erich. For some of those dogfaces he was the only father they ever knew. Don’t get me wrong, now, there was nothing unnatural about it; the colonel just has a heart bigger than any man I ever knew.’

The guitar music came to an end and Stein pushed the cassette back to repeat it. ‘How long since the colonel was stateside?’ Stein said.

‘Not since he got out of the army.’

‘That would be about 1948,’ said Stein. ‘It’s a long time.’ He watched the scenery. The Alps loomed large above them by now, and lost in the mist and cloud there were the Juras on the far side of the lake. It was cold near the water without the sunshine. Such a place would not suit Charles Stein; he found the surrounding mountains oppressive and the inhabitants cold and formal. They were near to the French frontier here but there could be no mistaking the Swiss orderliness as they passed through villages where the dogs were securely chained and the logs sorted by size before being stacked outside the houses

The Rolls turned in as soon as the gates swung open. The gravel crunched under the tyres and the Rolls moved slowly past the well-tended lawns and the summer house where Colonel Pitman sometimes took afternoon tea. The gravel drive ended in a circle round an ornate fountain. It provided an appropriate setting for the grand mansion that faced rolling lawns and shrubs as far as the trees that lined the lake shore. It was a sinister old place, thought Stein, The sort of large property that unscrupulous Geneva property salesmen are likely to say belonged once to Charlie Chaplin, Noel Coward or the ex-Shah of Iran. On the steps there was a servant in a green baize apron ready to help the driver with the guest’s baggage.

The house was a cheerless assembly of turrets and towers, looking like a scaled-down version of some neo-Gothic town hall. Inside, Stein’s footsteps clattered on the decorative stone. Even now, in May, it was chilly. The furniture was massive-shiny red mahogany sideboards and tall, glass-fronted cupboards filled with forgotten crockery. Four suits of armour were guarding the hallway, only the shine of their metal distinguishable in the gloom. On the hall table, under a large bowl of fresh flowers, were the day’s newspapers and some magazines and letters, all unopened and unexamined.

A servant showed Stein up to a bedroom on the first floor. Alongside a big mahogany bed with a cream silk duvet cover there was an antique table with fresh fruit in a bowl and a coffee-table book on vintage cars. Over the bed hung a painting by some Dutch eighteenth-century artist: sepia sailing barges, sepia water, sepia sky. The servant opened the windows to reveal a wrought-iron balcony just large enough to permit the window shutters to fold back fully and provide a view of the garden and the lake, colourless in the grey afternoon light.

‘Would you like me to unpack now, sir?’

‘No, I’m going to climb into a hot tub and get some of that travel dust out of my wrinkles.’

‘Very good, sir. You’ll find everything you need, I think.’ The servant opened the cabinet alongside the window. There were tumblers and wine glasses with some bottles of claret in a rack and an unopened bottle of Jack Daniel’s bourbon.

‘And in the ice box there’ll be branch water,’ said Stein delightedly. ‘The colonel never forgets a thing.’

‘That’s right, sir,’ said the servant. He paused respectfully and then said, ‘Dinner will be served at 7.30, sir. The colonel will have a drink in the study about seven. He would like you to join him there.’

‘I sure will,’ said Stein.

‘The bell is by the door should you require tea or coffee or anything to eat.’ He always said the same thing, but Stein did not interrupt, knowing that he preferred it this way: he was Swiss.

‘No, I’m just fine. I’ll see the colonel at seven, in the study.’

With a short bow, the servant departed. Stein opened the bottle of Jack Daniel’s and poured some down the sink. He had long since lost his taste for bourbon, but there was no point in hurting anyone’s feelings. After flushing some bottled water after it, Stein held the whisky to his nose. That sweet smell brought the memories flooding back upon him. He marvelled at the silence and stood for a moment or two in the sunless light, holding the whisky and looking out across the mauve rippling surface of the lake. From the hall below there came the soft chimes of the colonel’s favourite clock. He remembered his mother quoting the old Polish proverb, ‘In a house of gold, the hours are lead.’

Stein’s arrival at short notice meant that there were other guests for dinner. They were all casual acquaintances, people whom Pitman had met by way of business, A commodity broker from Paris on vacation with his wife and teenage daughter, and a French couple who owned a car-leasing agency in Zurich. The conversation was confined to polite banalities. So although Stein was able to outline the MacIver episode before the guests arrived, it was not until dinner was finished that Stein and Pitman were alone.

‘You’re looking well, Stein.’

‘You too, Colonel.’

‘What about a nightcap? Shall we see what we have in the cellar?’

It was always the same ritual. They went downstairs into the neatly arranged basement, passing the coal storage and the gleaming racks of logs to enter the long corridor where the wine was stored. ‘Claret or burgundy?’ the colonel asked.

‘The wine we drank at dinner was delicious.’

‘We might be able to do better than that,’ promised the colonel, searching carefully through the ranks of dusty bottles. ‘For an old army buddy we serve only the best.’

Behind the wine there was a storage area where old suitcases were piled. There were some stags’ heads and other hunting trophies there too, tusks and antlers grimy and cobwebbed. Stein remembered when they were the colonel’s pride and joy, but some of the boys from the battalion had made jokes about them at a party back in the late sixties, and the colonel had changed his mind about them. Colonel Pitman set great store by the opinion of his men. Perhaps sometimes he overdid this tendency.

‘Hermitage!’ said the colonel. ‘You’ll enjoy this one, I’m sure. It has the real flavour of the north Rhone and will make an interesting comparison with that Châteauneuf-du-Pape we had at dinner.’ The decision made, Pitman led the way upstairs to his study, negotiating the cellar steps with a care that made Stein concerned for him. ‘I get a little giddy sometimes,’ he explained.

‘Let me take that bottle, Colonel.’

Colonel Pitman held tight to the rail and picked his way up the steep steps. ‘I’ve never fallen,’ he explained, ‘but the light here is deceptive.’

‘All these wine cellars are the same,’ said Stein. “The steps wobble as you go out. You’ll have to cut back on the Evian water, Colonel.’

The colonel chuckled softly, appreciating Stein’s attempt to relieve his embarrassment.

They went to Pitman’s study. It was a small room, decorated like a businessman’s office. There was an oak desk arranged between the windows, two comfortable leather armchairs with a battered foot rest and brass ashtray near them. The walls were filled with photos and certificates and souvenirs of the colonel’s army days and his hunting expeditions. On the shelf near the door were some silver motor-racing trophies.
