Is A Spy Among Friends based on a true story or a book?

A Spy Among Friends is based on both a true story and a book. Kim Philby was a real spy who worked as a double agent for MI6 and the KGB. Author Ben Macintyre documented his story in his book A Spy Among Friends: Kim Philby and the Great Betrayal, which is the source material for the series.

Born in British India, Philby was born Harold Adrian Russell "Kim" Philby in 1912. Educated at Westminster School and Trinity College, Cambridge, he was recruited by Soviet intelligence in 1934. In 1940, he began working for MI6, becoming a high ranking member by the end of the Second World War. In 1963 it was revealed he was a member of the "Cambridge Five" - an infamous spy ring who divulged British secrets to Russia during World War II and the Cold War. 

Nicholas Elliot and Kim Philby really were spies and lifelong friends, but Philby was double crossing Elliott for the duration of their friendship and working relationship. Of the Cambridge Five, Philby is thought to have been most successful in passing secret information to the Soviets. When his actions were uncovered in 1963, Philby defected to Moscow where he lived out the rest of his days. He died in Russia in 1988, and is buried in Kuntsevo Cemetery, Moscow. He is considered the most notorious British defector and Soviet double agent in history.

First published in 2014, Ben Macintyre's book about Philby's life uses memoirs Philby wrote later in his life and secret British intelligence files, to uncover the real story behind his betrayal. The critically acclaimed book became a bestseller, and one Good Reads reviewer wrote about it, saying "I could write pages about this enthralling book but instead, I would recommend that you read it. You will shake your head in amazement at the devious and clever inner workings of such a trusted man who was a traitor to his country. I have the highest praise for this book."

A Spy Among Friends: Reviews

Early reviews from critics are largely positive, indicating A Spy Among Friends is worthy of the buzz its been generating.

Dan Einav from the Financial Times offered the show 4 out of 5. He said "For all the intricate plotting and fertile ambiguity, the show doesn’t lose sight of the more basic, universal tale it tells about the pain of betrayal. Lewis lowers his character’s patrician façade to show glimpses of a spy’s wounded pride and a friend’s hurt. Pearce meanwhile balances Philby’s haughtiness at having duped his 'sentimental, arrogant' colleagues, with snatches of affection and nostalgia."

Jasper Rees from the Daily Telegraph also offered 4 out of 5. He said "The densely webbed structure is much suited to a story where truth eludes capture."

Victoria Segal from the Sunday Times was also enthusiastic, adding "Based on Ben Macintyre’s 2014 book, this drama isn’t just about the brainy mechanics of espionage, it also interrogates the multifaceted human beings tangled in its webs."
