The Squire Quartet. Brian Aldiss

to Pippet Hall; later, Squire met the friendly man in Whitehall. Following a hot tip, Squire applied for a job with a consortium of manufacturers who were interested in new export markets. He got the appointment and went to night school to learn Serbo-Croat.

      War-battered Europe was putting itself together again. The Americans, with a gesture of unique generosity, launched the Marshall Plan. Britain, its overseas investments exhausted after paying for the war, set to work cheerfully on an export drive. The war had been won; now they were to win the peace.

      The frontiers of the peace were already established. The Iron Curtain had descended across Europe, and the luckless nations of the Continent found themselves either on one side or the other; with one exception. The nation of Yugoslavia.

      Although Yugoslavia was communist, there were remarkable differences between it and the other communist countries. Their leader, Tito, was a national hero and had conducted a formidably courageous war against the Nazis; he became a popular peacetime leader, and was not imposed on the country by the Soviet Union. Britain had supported Tito during the war; Churchill had made wise decisions there; so a friendship of sorts remained possible across barriers of ideology.

      The BIA (British Industries Abroad) opened an office in Belgrade and attempted to develop trade with the Yugoslavs only a comparatively few months after the official cessation of hostilities. On their staff was a young secretary, Thomas Squire, with a briefing to travel to all regions of Yugoslavia looking for trade. He had the perfect job for undercover work.

      ‘You may not like Yugoslavia very much until you settle in,’ Squire’s head of department said. ‘After that, you’ll hate it.’

      Squire loved it. There was something in this mountainous country – particularly in Serbia – in its songs, in its turbulent history, which corresponded to the violence trapped in his own nature. Moreover, a war was still going on, a war of minds. As an impoverished and broken economy picked itself up, the nation fended off its enemies. The Yugoslavs were intensely nationalistic, intensely suspicious. Foreigners were constantly watched.

      Belgrade, the Serbian and national capital, was at that time a city in ruins. Of the housing that remained, much was old and substandard; the energetic rebuilding was new and substandard. Greyness and cold prevailed. Filth, disease, misery, mud, flowed like blood through the ruptured veins of the capital. Food was short. It was all that Squire desired; here was the harshness and challenge of the world war he had missed.

      A Serbian girl called Roša came his way. He knew she was an agent. He embraced her as eagerly as he did his new life. In her pallor, her treachery, her nakedness, she was a paradigm of her country.

      ‘Obey your operating orders, whatever they are,’ he said – he rapidly became fluent in Serbo-Croat, ‘but make me part of you. Let’s do everything. Be extreme. Involve me, involve me!’

      He thought she loved him in a way. She tried to dye her hair blonde, with disastrous results. They both laughed; then she fought with him and wept. Her parents had been shot by Nazis for some petty offence. The country was an armed camp. The army built roads, bridges, bicycle factories. Ferocious drink-parties took place in which people fell out of windows and died. Roša got drunk and sang folk songs about the centuries of Turkish tyranny, the beauty of Serbian hills, and red wine spilt on white tablecloths. Her voice was like zeppelins crashing. It made him weep.

      Squire travelled down to wild cities in the south, Titov Veles, Kumanovo, Bitola, Prilep, Skopje. He passed on some information in Skopje, and two Russian agents were arrested. He saw how one of them was beaten up; he only just managed not to vomit, ashamed of his own weakness.

      Back in Belgrade. Roša had earned a rare holiday, she said. She took him on an old steamer down the Danube, brown with all the corpses of history. They stopped at Smederevo. Smederevo Fortress was one of the places Roša sang about when drunk. In its time it had been the largest fortress in all the Balkans. Its gigantic and ruinous towers stood against the Danube. It was a cold, depressing place; the wind blew from Russia. Masses of peasants had been forced to pile stone on stone, to erect this monstrous stronghold against the Ottoman Empire.

      There was no defence against history and the Turk. When Smederevo fell in 1459, the medieval state of Serbia was quenched like a torch in the river.

      A man was waiting for them in Smederevo. He was big and black-bearded. His name was Milo Strugar, and he became Squire’s friend. On that first occasion, he was hostile. He drove Roša and Squire away in an old black German car to a wooden-tiled house in the woods. There Squire was made privy to some of the plans of Yugoslav counter-intelligence.

      He never saw Roša again after that occasion. The bastards had sent her away, just to show him that you did what you were told. He learned the lesson.

      Long before the war, the Yugoslav and Soviet communist parties had forged close links; they were brother Slavs. But Stalin had offered Tito little support in his struggle against German invasion. The old channels of communication were now being obliterated. Yugoslavia had to stand on its own legs or fall under Soviet domination.

      Squire saw evidence of how ruthless both sides were. In this corner of Europe, in the broken towns and forests, the Cold War was real. Yugoslavia stood between East and West, mistrusting both; the fight was not merely of words, but of guns, fists and boots.

      Living became more complex while its issues simplified. The remnants of the fascist Ustache in Croatia, once linked to Hitler, were allying themselves with the Soviet Union. Their plan was to kill Marshal Tito. They had to be smashed. There were weeks, months, when tank movements on the other side of the frontier suggested that Soviet invasion was imminent.

      Squire thought much of his gentle father in those times. He thought of the dogs that had devoured his face. To some acts, there was no adequate response but killing. So in Serbia.

      He slept rough, became familiar with the forest. War was not a natural activity of man, but the equations of life forced it on him. He understood perfectly that the Yugoslavs had no alternative but to resist the Russians. Like tigers, they loved their freedom, and would defend it.

      More important to the strategists in the West was the fact that here communist was fighting communist for the first time. It gave cause for hope. The struggle was of immense significance for the rest of the world. As he identified with the Yugoslav cause, he saw clearly a parallel between his lonely war at one end of Europe and the role played at the other end of Europe by Britain, only seven years earlier.

      After Milo Strugar had tested him, the Yugoslavs began reluctantly to trust Squire. The Serbs preferred him to the Croats. In part, they trusted him because he was British. The label ‘Englishman’ was sweet in their mouths.

      Early in the ill year of 1948. Countries of Central Europe like Czechoslovakia sinking further under Russian ice. Romania becoming more sovietized, and more hostile to Yugoslavia. The USSR beginning to hamper traffic between Berlin and the West.

      The BIA sent Squire to the Yugoslav port of Rijeka, where mixed elements in the population caused unrest. Snipers still lurked in the hills above the city. Squire’s contact was a Serb called Slobodan, who ran a printing press as a cover for his other activities. Slobodan was a wild and unkempt man, extremely emaciated, who had lost his left eye in the mountains during his term as one of Tito’s partisans.

      Over cigarettes and slivovitz, and through many curses, Slobodan in his little oily shop explained how a shipment of arms of British manufacture had arrived in Rijeka from the British Zone in Germany. It was delivered in an armoured freight train, and the train was hauled into railway sidings near the docks, where it was guarded by a Special Operations unit of the Yugoslav Army. Regulars, not conscripts, said Slobodan, spitting. After some delay, the officer commanding Rijeka Arsenal – sited some miles inland from Rijeka – arrived with a convoy of trucks to take charge of the shipment. The train was empty.

      The major had immediately arrested the captain in charge of the guard unit, the driver and engineer of the train, the train guards, and just about all the officials connected with port operations. But the arms were not recovered.

      A full-scale search of Rijeka was in
