Overview

Kim Philby reaches the peak of his power as MI6's head of station in Washington in 1949, liaising with the newly formed CIA while secretly feeding intelligence to Moscow. His position gives him unprecedented access to Anglo-American covert operations against the Soviet bloc, but the net is slowly closing around him as investigations into wartime leaks begin, and his friendship with the chaotic Guy Burgess threatens to expose everything.

Philby's Journey to Washington: The Perfect Position

In October 1949, Kim Philby arrives in Washington as MI6's head of station, a role he immediately recognizes as more valuable to his Soviet handlers than even running Soviet counterintelligence inside MI6. At just 37 years old, he's positioned at the absolute heart of the emerging Cold War, spending a month at MI6 headquarters being briefed on everything the service is doing. During this period, he learns that both the US and UK are investigating leaks from the British embassy in Washington during 1944-45, and he immediately suspects his Cambridge friend Donald Maclean.

Building Relationships with American Intelligence

Philby cultivates crucial relationships with CIA and FBI leadership, particularly with James Jesus Angleton, who becomes a close friend and mentor figure. The CIA is just two years old, scattered across shabby buildings in Washington, and the British see themselves as teachers to the Americans. Philby visits CIA headquarters 113 times, has unrestricted access, and hosts lavish parties at his house on Nebraska Avenue, all while the Americans view him as a rising star and trusted ally.
