Ted Mundy, a rootless Englishman born in Pakistan, forms a lifelong bond with the radical German Sasha during the student protests of 1960s West Berlin. Their friendship draws them into Cold War espionage as double agents, and years later, after the fall of the Berlin Wall, a chance reunion pulls the aging pair into a dangerous new operation amid the post-9/11 world of shifting alliances and manufactured threats.

John le Carré delivers a compelling character study wrapped in a bitter political thriller, tracing idealism, betrayal, and the personal cost of intelligence work across decades. While the later sections grow more overtly polemical and the plot turns increasingly conspiratorial, the novel’s rich portrait of friendship and its sharp critique of power remain powerful and unmistakably the work of a master of the spy genre.
