Utopia and Espionage
The convergence of progressive idealism and Soviet espionage in the Isokon building is one of the more remarkable stories of twentieth-century London history — a story that illustrates, with unusual clarity, the way in which the political urgencies of the 1930s could draw even the most cultured and idealistic people into the darker reaches of geopolitical conflict. The building's reputation as a centre of anti-fascist modernism made it a natural environment for people who combined genuine cultural achievement with covert political activity, and the resulting mixture was both intellectually distinguished and morally complex.
The context was the crisis of European liberalism in the 1930s. The Depression had shattered confidence in the capitalist economic system. Fascism was rising across Europe, with Hitler's seizure of power in 1933 and Mussolini's consolidation of power in Italy providing templates for what appeared to many intelligent observers to be an inexorable process. The Soviet Union, for all its demonstrable failures and cruelties — the purges, the collectivisation famines, the systematic terror — appeared to many progressive intellectuals as the only serious alternative to fascism, the only society that had actually attempted to build on socialist principles. The moral calculus that led intelligent people to the Communist Party or to cooperation with Soviet intelligence in the 1930s was a calculus born of genuine desperation, not mere naivety.
The Isokon building attracted people who had made some version of this calculus. The Central European refugees who settled there — many of them with direct experience of the fascist destruction of the political and cultural world they had belonged to — were overwhelmingly anti-fascist in their politics, and many were also sympathetic to Communist internationalism in ways that made them susceptible to Soviet approaches. The British residents and visitors included figures from the left wing of the Labour Party and the intellectual circles around the Communist Party who shared, at least in theory, the commitment to anti-fascist solidarity that Soviet intelligence exploited.
The Cambridge Five Connection
The connections between the Isokon milieu and the Cambridge Five — Kim Philby, Guy Burgess, Donald Maclean, Anthony Blunt, and John Cairncross — were mediated primarily through Arnold Deutsch, the Austrian-born Soviet intelligence officer who ran the Five's recruitment and management during the critical years of the 1930s. Deutsch was a man of considerable intellectual sophistication and social charm, well suited to the progressive circles of NW3, and his connections to the Isokon world — through friends and associates in the Austrian refugee community — gave him access to a milieu that was both politically sympathetic and socially removed from the obvious targets of British counter-intelligence surveillance.
The specific intelligence activities connected to the Isokon building have been the subject of extensive investigation by historians and former intelligence professionals, but the full picture remains incomplete. The available evidence suggests that the building was less a formal intelligence base than an informal social environment in which sympathetic individuals could be identified, cultivated, and occasionally recruited — a process that depended on the opacity of the building's social world and the genuine political sympathies of many of its residents.
Melita Norwood, who became one of the most significant Soviet agents in British history, had connections to the Isokon milieu through the left-wing professional networks of the 1930s. Andrew Rothstein, the son of the prominent Communist Theodore Rothstein, was a regular visitor. The pattern of connection — political sympathy, social proximity, intelligence opportunity — was consistent across many of the building's significant associations.
Agatha Christie in the Spy Den
Perhaps the most incongruous element of the Isokon intelligence story is the presence, among its most celebrated residents, of Agatha Christie — the queen of the detective novel, a woman whose politics were straightforwardly conservative and whose cultural values were entirely conventional. Christie lived at the Isokon during the Second World War, choosing its anonymous modernity as a practical solution to the problem of finding accommodation in a London disrupted by bombing and evacuations, apparently without any awareness of the intelligence activities that her neighbours were engaged in.
The irony is almost too neat for fiction: the writer whose novels are premised on the proposition that careful observation of one's environment and neighbours can reveal hidden crimes, living in a building where hidden crimes of a sort were genuinely taking place. Christie seems to have been entirely oblivious to the intelligence dimension of her surroundings — she was preoccupied with her writing, with her marriage to Max Mallowan, and with the practical difficulties of wartime life in London — and her presence at the Isokon is one of the many biographical details that make the building's history simultaneously comic and serious.
Christie's Isokon period was, incidentally, among her most productive. Several of the novels she wrote during the war years — including N or M? (1941), which featured a plot about Nazi fifth columnists operating in a seaside guesthouse that bears some resemblance, in its social dynamics if not its politics, to the Isokon itself — were written in the Lawn Road flat. The experience of living at close quarters with a diverse community of modernist intellectuals and Central European refugees, whatever its intelligence dimensions, seems to have been artistically generative.
The Historical Verdict
The historical assessment of the Soviet espionage connections to the Isokon building is complicated by the moral ambiguity of the political context in which they occurred. The people who cooperated with Soviet intelligence in the 1930s were, in many cases, motivated by genuine horror at fascism and genuine, if misplaced, belief in the Soviet alternative. The damage they did — through the leakage of British intelligence to a state that was, by the late 1940s, clearly an adversary — was real, and some of it was serious. But the moral landscape of the 1930s was genuinely different from that of the Cold War, and judgements formed in one context do not necessarily apply to decisions made in another.
What the Isokon intelligence story illustrates, perhaps more clearly than anything else, is the way in which the political urgencies of a particular historical moment can penetrate even the most aesthetically rarefied environments. The Isokon building was a monument to a particular vision of progressive modernity, and that vision was not separate from the political world that surrounded it. The building's residents were people of their time — shaped by the crises and choices of the 1930s and 1940s, and acting on their best understanding of what those crises required. That their actions were sometimes mistaken, and sometimes harmful, does not make them less interesting, or their building less significant.
The Spy Trail Today
The Isokon Gallery, established in the restored building on Lawn Road, tells the story of the building's modernist heritage with appropriate care and detail. The intelligence story is part of this narrative, handled with the nuance that the historical complexity requires. Visitors who come to see the architecture and the design legacy — the Breuer furniture, the Gropius influence, the Wells Coates design — also encounter the intelligence dimension of the building's history, presented as one element of a complex and fascinating story rather than as its defining characteristic.
The building itself, its white render restored to something close to its original brilliance, stands on Lawn Road as a monument to an extraordinary decade. The Belsize Park neighbourhood that surrounds it has changed beyond recognition since the 1930s, but the building's presence on its original site maintains a connection to the world that produced it — a world of crisis and creativity, of exile and experiment, of utopian aspiration and geopolitical shadow, that shaped the character of NW3 in ways that are still felt today.
