All the good spy stories I've read (and I've done a good bit of reading, and would recommend Tony Mendez's The Master of Disguise as an easy introduction) have been about the people and the subtle craft of espionage, which is not something Hollywood gets very well (see Argo). James Bond and Jason Bourne are exciting to watch, but I much prefer John le Carré's George Smiley, where spycraft is never in the open, never loud and actiony, but always for high stakes. Thanks for reading!
