The latest book on the Cambridge spy ring, Stalin’s Apostles: The Cambridge Five and the Making of the Soviet Empire by journalist and podcaster Antonia Senior, offers a detailed accounting of the damage inflicted by the five Soviet agents recruited from the 1930s to the early 1950s. While it does not overturn established narratives, it quantifies the flow of secrets to Moscow and highlights the British establishment’s failure to act on obvious warning signs.
The Cambridge Five
The group comprised Kim Philby, Donald Maclean, Guy Burgess, Anthony Blunt and John Cairncross. All were educated at elite universities, most notably Cambridge, and each went on to hold positions of considerable influence within the British state.
- Kim Philby – son of a noted Arabist, radicalised at Cambridge, later worked for a right‑leaning newspaper and praised Franco’s forces in Spain. He rose to become the British intelligence liaison in Washington after the war.
- Donald Maclean – son of a former cabinet minister, openly admitted his communist sympathies during a Foreign Office interview yet was still hired.
- Guy Burgess – an alcoholic with a penchant for gossip, built a career at the BBC before moving into MI6.
- Anthony Blunt – a distinguished art critic whose MI5 contacts opened a pathway into the security service.
- John Cairncross – the outsider of the group, leveraged an outstanding Cambridge record into posts at the Foreign Office, Bletchley Park and as an adviser on atomic research.
Only three of the five – Burgess, Blunt and Cairncross – belonged to the secret Cambridge society known as the Apostles, making the book’s title a slight misstep.
How the Ring Operated
Senior’s research tracks the flow of classified material. Maclean, for example, smuggled out such a volume of documents that his Soviet handlers ran out of film to copy them. Philby and Blunt supplied intelligence on anti‑Soviet sources across Europe, while Maclean passed on the wartime strategic aims of Churchill and Roosevelt concerning the Balkans and Greece.
After the war Philby betrayed resistance networks in Lithuania, Poland and Ukraine and warned Moscow in time to thwart British and American attempts to infiltrate agents into Albania. The human cost of these betrayals, Senior estimates, ran into the hundreds of lives.
Security Establishment’s Blind Spot
The book delivers a sharp critique of the British security apparatus of the period. Repeated signs – drunken brawls, reckless conduct and overt friendships with known risks – were dismissed as minor faults rather than disqualifications for handling state secrets.
Senior’s most valuable contribution is the systematic tally of the secrets that reached the Soviet Union, providing a clearer picture of the strategic advantage gained by Stalin’s regime.
