The Billion Dollar Spy: A True Story of Cold War Espionage and Betrayal

After reading about how Kim Philby played the UK and US for so long in the Soviet Union’s favor, I was happy to learn the story of a dramatic spy operation going the other direction. This is the story of the most impactful spy that the US had against the Soviet Union, and possibly the first inside Moscow (right under the KGB’s noses). The book dives into spycraft, which is really interesting. (View on Amazon)

A Spy Among Friends: Kim Philby and the Great Betrayal

Kim Philby was an upper-class English guy who went to the “right” prep school and college, then joined the intelligence service during WW2. He rose to become the head of counterintelligence at MI6, focused specifically on the Soviet Union.
