Book cover of The Poet's Game

Kenneth Dekleva Author Of The Expediter

From my list on spy thrillers read in one sitting.

Why am I passionate about this?

I am a psychiatrist, novelist, and former diplomat, who served overseas in Europe, Russia, Mexico, and India. My diplomatic travels took me to over 70 countries over many decades. I have always been passionate about spy thrillers, because they highlight the intrigue, drama, psychology, and history of different cultures, which brings out the humanity, courage, and tragedy of the characters therein. The best spy thrillers also capture a sense of place, culture, and history, and possess an authenticity that gives them a broader, universal appeal.

Kenneth Dekleva Why Kenneth loves this book

I have always loved Vidich’s portrayals of the Cold War between the USSR (now Russia) and the West, and his newest novel appealed to me because of its modern-day version of this struggle.

I liked the plot and characters, especially the protagonist Alex Mathews, a former CIA officer who has served in Moscow for many years, and the physical, emotional, and psychological toll that Moscow – a city which “has drawn him to her warm bosom” – leaves him with.

I loved the novel’s settings and place, and I found myself rooting for Alex as he struggles to adapt to the ‘Moscow Rules’ and ‘getting off the X.’  At the novel’s conclusion, I realized, like Alex, that the Cold War had never really ended.

What is this book about?

'In The Poet's Game, Vidich confirms his place in the pantheon of the new generation of spy novelists. Once again, his elegant, finely developed characters add nuance and depth to a fast-paced story' Financial Times

'Vidich details political gamesmanship with an exactitude in the tradition of John le Carre, whose influence he ably honours' Irish Times

'We all have dreams and then we wake up.'

Alex Matthews thought he had left it all behind. His CIA career, the viper's den of bureaucracy at headquarters and the lies and stress of the cat and mouse game of double agents. But then…

Kenneth Dekleva Why Kenneth loves this book

Lawler, as a former CIA case officer, brings tremendous authenticity and verve to his spy novels, and The Traitor’s Tale is no different. 

I loved the fast-moving, vibrant plot, and I appreciated the characters, both the protagonists (especially Ambrose, Shawnee Chasing Hawk, and Gary Trichter). I enjoyed the intricate plot of espionage, recruitment, betrayal, a love story, and its finale. 

Lawler’s book appealed to me because it reveals the very human side of espionage, which, in the end, is about relationships between human beings—between intelligence officers and their agents/spies.

I have always enjoyed McCloskey’s spy novels, especially those set in the Middle East.

His newest, a tale of espionage and betrayal set in Iran, appealed to me because of its characters—an Iranian dentist recruited by Mossad as an agent, his Mossad spy handler, and their Iranian adversaries. I loved the realism and grittiness of this tale, and its portrayal of the human costs of espionage, and its betrayals, fault lines, and tragedies.

I love how McCloskey, a former CIA analyst, humanizes his characters, both the Israelis and the Iranians, showing us their human frailties, loyalties, and passions.

Kenneth Dekleva Why Kenneth loves this book

I loved Yariv Inbar’s tale, one of the best that I have read in years.

As a Mossad officer and novelist, he brilliantly captures the intricacies and nuances of espionage in a tale involving Irit, a Mossad officer, and her protagonist Noor, the wife of a Syrian WMD expert whom Irit hopes to recruit. I enjoyed how Inbar captured the intimacy of espionage, and the different stages of its life cycle, and how such things often end tragically, with multiple sorrows and traumas.

My other favorite character was Menachem, a former Mossad officer turned psychotherapist, who advises Mossad and Irit along the way, bringing an additional human touch to this singular novel.

What is this book about?

What if one impossible decision during a suspenseful mission shattered everything you believed about your past?

Set deep within the world of contemporary Israeli espionage, Behind the Trigger is a psychological spy thriller where covert operations collide with buried trauma, and the cost of trust is life or death.

Irit is no cliché female protagonist. She’s a Mossad field agent, mother, and wife - trained to complete missions, not confront her past. But when a thrilling assignment sparks an unexpected connection with Noor - the wife of a Syrian missiles engineer - everything changes.

Two strong female main characters, both…


Book cover of Spymaster: My Thirty-Two Years in Intelligence and Espionage Against the West

Mark Hollingsworth Author Of Agents of Influence: How the KGB Subverted Western Democracies

From my list on the KGB, Russia and espionage.

Why am I passionate about this?

I have been writing about Russia for the past 20 years for all the UK national newspapers, The Spectator and contributed to several TV documentaries. I am fascinated by Russia which is a unique country and has been a major influence on the world for the past 100 years. Based on new documents, my book Londongrad - From Russia with Cash revealed how Russian Oligarchs made their wealth, moved it out of Russia, hid their fortunes and then parked and spent it in London. My new book - Agents of Influence - provides an insight into how the KGB influenced the West based on new archives.

Mark's book list on the KGB, Russia and espionage

Mark Hollingsworth Why Mark loves this book

It is rare for a KGB spy to reveal so many secrets about the Soviet Union and Russian intelligence operations in the West and so this book is a revelation. 

Kalugin was a KGB officer based in the USA in the 1970s and he describes all their dirty tricks - fake letters, disinformation, honey trapping, and even attempts to bug the US Congress.

By Oleg Kalugin ,

Why should I read it?

2 authors picked Spymaster as one of their favorite books, and they share why you should read it.

What is this book about?

Oleg Kalugin oversaw the work of American spies, matched wits with the CIA, and became one of the youngest generals in KGB history. Even so, he grew increasingly disillusioned with the Soviet system. In 1990, he went public, exposing the intelligence agency's shadowy methods. Revised and updated in the light of the KGB's enduring presence in Russian politics, Spymaster is Kalugin's impressively illuminating memoir of the final years of the Soviet Union.


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

Steve Vogel Author Of Betrayal in Berlin: The True Story of the Cold War's Most Audacious Espionage Operation

From my list on accurate non-fiction about Cold War espionage.

Why am I passionate about this?

I am an author and veteran journalist who reported for The Washington Post for more than two decades, and I write frequently about military history and intelligence. My father worked for the CIA, and I was born in Berlin when he was stationed there as a case officer. Later I was based in Germany as a foreign correspondent when the Berlin Wall came down. So it’s not too surprising that I am interested in Cold War espionage and history. As a reporter, author, and reader, I’ve always been attracted to stories off the beaten track, the ones that most people know little or nothing about.

Hoffman tells the previously little-known story of Soviet military engineer Adolf Tolkachev, whose disgust with the communist regime inspired him to turn over enormously valuable secrets to the CIA station in Moscow beginning in the late 1970s.

Book cover of Spies: The Rise and Fall of the KGB in America

Brian B. Kelly Author Of Communist Number One, Volume I

From my list on the idealistic spies Joel Barr, Alfred Sarant, and Julius Rosenberg.

Why am I passionate about this?

I became fascinated with the collapsing USSR upon my first trip to Moscow in 1990, and made contact with Joseph Berg, a man suspected of being Joel Barr, a Soviet Spy and close friend of Julius Rosenberg. I subsequently co-hosted Barr’s first visits back to America in an effort to obtain his true story. This led to an agreement to write a novel based on his life, which led to a close association and friendship. As I got to know Barr, he also introduced me to Morton Sobell. I became absorbed in the stories of these men who were motivated by political idealism to aid the Soviet Union in matching the United States in military power.

Brian B. Kelly Why Brian loves this book

This book is the most comprehensive account of KGB spying in America and two of its authors have studied the subject exhaustively for decades and the third author is a Soviet ex KGB agent with firsthand knowledge of and access to Soviet KGB files.

What is this book about?

An unprecedented expose of Soviet espionage in the United States during the 1930s and 40s

This stunning book, based on KGB archives that have never come to light before, provides the most complete account of Soviet espionage in America ever written. In 1993, former KGB officer Alexander Vassiliev was permitted unique access to Stalin-era records of Soviet intelligence operations against the United States. Years later, living in Britain, Vassiliev retrieved his extensive notebooks of transcribed documents from Moscow. With these notebooks John Earl Haynes and Harvey Klehr have meticulously constructed a new, sometimes shocking, historical account.

Book cover of Deep Undercover: My Secret Life and Tangled Allegiances as a KGB Spy in America

Daniela Tully Author Of Hotel on Shadow Lake: A Spellbinding Mystery Unravelling a Century of Family Secrets

From my list on East Germany from an insider's point of view.

Why am I passionate about this?

I grew up in Germany and have been living all over the globe since I was 18, including the US. I married a New Yorker 15 years ago. I am drawn to stories that combine both the German and American cultures — two worlds I feel at home in — and as reflected in my debut novel. The next one will take place between the US and East Germany - we had relatives on the other side of the Iron Curtain whom we visited frequently. I will never forget surprising my 17-year-old cousin sitting alone in the garden, crying… over a can of Coke that we had smuggled over the border to him.

Daniela's book list on East Germany from an insider's point of view

Daniela Tully Why Daniela loves this book

Before stumbling across this memoir, while doing the research for my next novel, I had no idea that the Cold War saw German Communist spies living in the USA - but come to think of it, why shouldn’t they have existed on the other side of the Iron Curtain? Barsky’s story blew me away: he was sent by the KGB to the States as a sleeper agent. What “broke” him was not his challenging profession, but the love for his child — he eventually had two families, one in East Germany with a wife who knew about his true identity - and another one in the States, with a wife who didn’t.

He had a son with the German and a daughter with his Latin-American wife in the US. He wasn’t there when his son was born, but witnessed the birth of his daughter. When the Cold War ended and…

Book cover of Spies: The Epic Intelligence War Between East and West

M. B. Courtenay Author Of A Spy Inside the Castle

From my list on how the world actually works.

Why am I passionate about this?

I write spy fiction because I’ve lived close to the seams of power—working and traveling across the U.S., Europe, and China—and I’m obsessed with how ideas turn into decisions. I read philosophy for clarity, history for humility, and intelligence studies for the uncomfortable truth that good intentions aren’t enough.

My novel, A Spy Inside the Castle, grew from years of research and the harder work of translating it into human stakes. I’m passionate about books that illuminate secrecy and strategy without losing sight of people. These five shaped my thinking and, more importantly, kept me honest on the page.

M. B. Courtenay Why M. B. loves this book

I was drawn to Walton because he shows the CIA and other services evolving over decades, almost like living ecosystems.

What I valued most was how he highlights technology’s growing role in shaping intelligence work—how tools and data became as decisive as human agents. That perspective mirrored my own fascination with labyrinths: systems that adapt, feed on complexity, and reshape themselves in response to pressure.

Walton’s history is sweeping yet precise, and it left me seeing the intelligence world as something organic, not static—a reminder that secrecy and technology co-evolve, often faster than our ability to control them.

Book cover of Lenin on the Train

Erik C. Landis Author Of Bandits and Partisans: The Antonov Movement in the Russian Civil War

From my list on Russia’s Revolution and Civil War.

Why am I passionate about this?

I grew up in the United States, completed my undergraduate degree there, and then pursued a doctorate in Modern History at the University of Cambridge. Now, I teach European history at Oxford Brookes University and publish research on Russia and the Soviet Union. I have always been fascinated by revolutions and civil conflicts, especially how people navigate the disruption of stability and normality. How they process fragmentary information, protect themselves, and embrace new ideas to give meaning to their threatened lives is central to my work as a historian. The Russian Revolution and Civil War offer a rich tapestry for exploring these dilemmas.

Erik's book list on Russia’s Revolution and Civil War

Erik C. Landis Why Erik loves this book

This book narrowly focuses on one of the most famous moments that putatively determined the course of Russian and world history in the 20th century—Lenin’s journey from exile in Zurich, through enemy territory, to Petrograd in April 1917. The journey acquired infamy because it was facilitated by the German Army and government.

Leaving to one side consideration of counterfactuals or “what-ifs,” I loved Merridale’s book because it manages to capture so many worlds—the world of Russian revolutionary politics and exile, of espionage during WWI, and the early weeks of the Revolution of 1917—all while maintaining a focus on the human level of a train journey.
