I observed the way Bret was eying von Munte, whose stream of high-grade information had taken Bret into the very top ranks of the Department. Bret's desk was now closed down and his seniority had been in peril ever since the old man had been forced to flee. No wonder the two men watched each other like boxers in a ring.

Talk became more serious when it touched upon that inevitable subject in such company, the unification of Germany. 'How deeply ingrained in East Germans is the philosophy of Communism?' Bret asked von Munte.

'Philosophy,' said Silas, interrupting sharply. 'I'll accept that Communism is a perverted sort of religion – infallible Kremlin, infallible Vatican – but philosophy, no.' He was happier with the von Muntes here, I could tell from the tone of his voice.

Von Munte didn't take up Silas's semantic contention. Gravely he said, 'The way in which Stalin took from Germany Silesia, Pomerania and East Prussia made it impossible for many of us Germans to accept the USSR as a friend, neighbour, or example.'

That's going back a long while,' said Bret. 'Which Germans are we talking about? Are young Germans interested in the tears and cries of pain we hear about the lost territories?' He smiled. This was Bret being deliberately provocative. His charming manner was frequently used like this – the local anaesthetic that accompanied the lancet of his rude remarks.

Von Munte remained very calm; was it a legacy of years of banking or years of Communism? Either way, I'd hate to play poker against him. 'You English equate our eastern lands with Imperial India. The French think we who talk about reasserting Germany 's border to the frontiers of East Prussia are like the pieds-noirs, who hope once again to have Algeria governed from Paris.'

'Exactly,' said Bret. He smiled to himself and ate some duckling.

Von Munte nodded. 'But our eastern provinces have always been German and a vital part of Europe 's relationship with the East. Culturally, psychologically and commercially, Germany 's eastern lands, not Poland, provided the buffer and the link with Russia. Frederick the Great, Yorck and Bismarck – and indeed all those Germans who instituted important alliances with the East – were ostelbisch, Germans from the eastern side of the River Elbe.' He paused and looked round the table before going on with what was obviously something he'd said time and time again. 'Czar Alexander I and Nicolas who succeeded him were more German than Russian, and they both married German princesses. And what about Bismarck who was continually defending Russian interests even at the expense of Germany 's relations with the Austrians?'

'Yes,' said Bret sardonically. 'And you have yet to mention the German-born Karl Marx.'

For a moment I thought von Munte was going to reply seriously to the joke and make a fool of himself, but he'd lived amid signals, innuendoes, and half-truths long enough to recognize the joke for what it was. He smiled.

'Can there ever be lasting peace in Europe?' said Bret wearily. 'Now, if I'm to believe my ears, you say Germany still has territorial aspirations.' For Bret it was all a game, but poor old von Munte could not play it.

'For our own provinces,' said von Munte stolidly.

'For Poland and pieces of Russia,' said Bret. 'You'd better be clear on that.'

Silas poured more of his precious Chateau Palmer in a gesture of placation for all concerned. 'You're from Pomerania, aren't you, Walter?' It was an invitation to talk rather than a real question, for by now Silas knew every last detail of von Munte's family history.

'I was born in Falkenburg. My father had a big estate there.'

'That's near the Baltic,' said Bret, feigning interest to make what he considered a measure of reconciliation.

' Pomerania,' said von Munte. 'Do you know it, Bernard?' he asked me, because I was the closest person there to being a fellow-countryman.

'Yes,' I said. 'Many lakes and hills. They call it Pomeranian Switzerland, don't they?'

'Not any longer.'

'A beautiful place,' I said. 'But as I remember it, damned cold, Walter.'

'You must go in the summer,' said von Munte. 'It's one of the most enchanting places in the world.' I looked at Frau Doktor von Munte. I had the feeling that the move to the West was a disappointment for her. Her English was poor and she keenly felt the social disadvantage she suffered as a refugee. With the talk of Pomerania she brightened and tried to follow the conversation.

'You've been back?' Silas asked.

'Yes, my wife and I went there about ten years ago. It was foolish. One should never go back.'

'Tell us about it,' said Silas.

At first it seemed as if the memories were too painful for von Munte to recount, but after a pause he told us about his trip. 'There is something nightmarish about going back to your homeland and finding that it's occupied exclusively by foreigners. It was the most curious experience I've ever had – to write "birthplace Falkenburg" and then "destination Zlocieniec".'

'The same place, now given a Polish name,' said Frank Harrington. 'But you must have been prepared for that.'

'I was prepared in my mind but not in my heart,' said von Munte. He turned to his wife and repeated this in rapid German. She nodded dolefully.

'The train connection from Berlin was never good,' von Munte went on. 'Even before the war we had to change twice. This time we went by bus. I tried to borrow a car, but it was not possible. The bus was convenient. We went to Neustettin, my wife's home town. We had difficulty finding the house in which she'd lived as a child.'

'Couldn't you ask for directions?' said Frank.

'Neither of us speaks much Polish,' said von Munte. 'Also, my wife had lived in Hermann-Göring-Strasse and I did not care to ask the way there.' He smiled. 'But we found it eventually. In the street where she lived as a girl we even found an old German woman who remembered my wife's family. It was a remarkable stroke of luck, for there are only a handful of Germans still living there.'

'And in Falkenburg?' said Silas.

'Ah, in my beloved Zlocieniec, Stalin was more thorough. We could find no one there who spoke German. I was born in a house in the country, right on the lake. We went to the nearest village and the priest tried to help us, but there were no records. He even lent me a bicycle so that I could go out to the house, but it had completely disappeared. The buildings have all been destroyed and the area has been made into a forest. The only remains I could recognize were a couple of farm buildings a long way distant from the site of the house where I was born. The priest promised to write if he found out any more, but he never did.'

'And you never went back again?' asked Silas.

'We planned to return, but things happened in Poland. The big demonstrations for free trade unions and the creation of Solidarity was reported in our East German newspapers as being the work of reactionary elements supported by western fascists. Very few people were prepared to even comment on the Polish crisis. And most of the people who did talk about it said that such 'troubles', by upsetting the Russians, made conditions worse for us East Germans and other peoples in the Eastern Bloc. Poles became unpopular and no one went there. It was as if Poland ceased to exist as a next-door neighbour and became some land far away on the other side of the world.'

'Eat up,' said Silas. 'We're keeping you from your lunch, Walter.'

But soon von Munte took up the same subject again. It was as if he had to convert us to his point of view. He had to remove our misunderstandings. 'It was the occupation zones that created the archetype German for you,' he said. 'Now the French think all Germans are chattering Rhinelanders, the Americans think we are all beer-swilling Bavarians, the British think we are all icy Westphalians, and the Russians think we are all cloddish Saxons.'
