What’s a good educational book explaining and teaching about Cold War Spies, Espionage, Secret Missions, etc?

Hello!

I’ve always been really big into history, and for a while now I’ve been very interested in the Cold War.

One of the main things that sticks out to me about it is the secrecy, spies, espionage, covert-missions, CIA, etc.

Ive recently fell in love with watching documentaries about USA Spies and CIA agents which turn to help the USSR and stuff of that nature too.

So, I’m asking for help on finding a specific book:

I’m looking for a book which is more educational and teaches about / explains the Spies, Espionage, Secrecy, Covert-Missions, CIA part of the Cold War, what they did in the Cold War, what the Cold War was, things along those lines.

I’ve been having issues with only being able to find story-books about one persons perspective, but I just want an educational explanation book.

Thank you for your time and help!

TL:DR: Looking for an educational book that teaches about / explains the Spies, Espionage, Secrecy, Covert-Missions, CIA part of the Cold War, what they did in the Cold War, what the Cold War was.
