Based on true events, A Spy Among Friends tells the story of Kim Philby (Guy Pearce) and Nicholas Elliot (Damian Lewis), best friends who worked for MI6, that is until Philby defected to the Soviet Union. Subject to inquisition and intense scrutiny, Philby and Elliot test the strength of their friendship against growing political turmoil.

The series starts slow and the dialogue, while smart, can get heavy-handed. But if you give it some time, the payoffs are rewarding. The sets are immersive as it spans different eras and countries; the actors are charismatic as they present enigmatic layers for us to unfold; and the particulars of espionage manage to feel freshly shocking in a story told many times before. 

Artful, well-performed, and gripping, A Spy Among Friends is a great watch for fans of voluble but intelligent thrillers.
