The best spy books that bring you close to what deeply drives people to become spies

I have read this novel twice and will undoubtedly read it again. It’s captivating because of the suspenseful plot and the perfect story structure, which is my favorite part of writing books.

The reality of the WWII challenges that the main players must face is gripping. It’s a reminder of how courage springs forth when fear is so overwhelming that there is no other choice but to be brave and do things you never believed you could do.

That is true for the Nazi spy who usually killed anyone who got in his way and for the woman who risked her life to, indeed, get in his way. Why he became a spy and why she tried to stop him are superbly revealed.

I read this unforgettable, true story, cover to cover while sitting for hours in the Denver airport waiting for a long-delayed flight to Seattle.

Thanks to Ben Macintyre’s brilliance, my day of stress became a meaningful and hugely informative adventure into the double life of Oleg Gordievsky. How this man, like his father and brother, joined the KGB; why certain realities and events during his KGB assignments changed him; what motivated his decision to become a double agent for British intelligence; and how he survived it all filled this saga with astute lessons about espionage.

There’s a simple yet profound line that stuck with me about the double life, something like: You love those around you while you conceal your true inner self.

Knowing about Noor Inayat Khan’s life is crucial to understanding why people become spies; her story is utterly startling.

I learned about Noor (codename Madeleine) while doing research in London for my fifth book. One of the people I interviewed was well-informed about the women who were trained as spies in WWII for Winston Churchill’s Special Operations Executive (SOE).

During that trip, someone left a copy of her biography, Spy Princess (a 2006 British publication), for me at the hotel front desk; to this day, I don’t know who. I read it on the flight back to the U.S. and was immensely moved by Noor’s motivations and her shocking bravery, especially after she faced the Gestapo and was sent to a concentration camp. 

What an eye-opener! I read this book one winter weekend in 2019 while researching early Soviet espionage in America to learn about the plan that Stalin and Soviet spy Stanislav Shumovsky set into motion in the U.S. in the 1930s. It reveals how trained Soviet spies were planted as students at American universities that ranked high in science education–starting with MIT.

As a model, Shumovsky earned a bachelor’s degree at MIT, joined professional societies to mingle with respected scientists, and focused his master’s degree on “high altitude flying,” sending mounds of information back to the USSR. However, it was not only what he sent home that made Shumovsky so important; it was what he set up for future spies who enrolled at MIT as well as Harvard and Columbia.  

I have read several John Le Carre novels, but I chose this one because of its ingenious depiction of the psychological traps of spydom.

It’s a satire, and as it moves through a mire of lies and deceit, it digs deeply into the twists and turns of the life of a tailor seemingly forced by bribery and blackmail to be a spy. His only freedom is to release his creativity into a vast new domain of endless deceit, in which, among other things, he drenches his handler with lies.

The story is brimming with surprises, including the fact that there’s no violence, which is one of the reasons I liked it so much. I read this one twice, years ago, and both times, I could barely take a break.
