1. Tinker, Tailor, Soldier, Spy (John Le Carré)

Occasionally referred to as the best espionage fiction ever written, this book is near the top of most fiction lists, not just spy thrillers. Espionage thrillers are known for their layers of conspiracy, twists, lies, moles, snitches, and mystery. This book does those things better than most. It stands out among other espionage novels because its depth and layers were so perfectly intertwined that the average reader could not pull ahead of the protagonist.

This is the story of George Smiley, a retired spy, pulled back into the game to figure out who the mole is within the British Secret Intelligence Service. In a story all about betrayal and trust, Smiley has to suspect everyone of being the mole within Britain’s Secret Intelligence Service, including those who he has known, worked with, and trusted for years.
