About this listen

le Carré meets Black Mirror in this cerebral espionage thriller about secrets, power, and the cost of truth.

When intelligence analyst Ethan Briar is drawn into a covert mission on the windswept Isle of Skye, he enters a world where nothing is as it seems. An abandoned supercomputer, a defector's warning, and the specter of a long-buried betrayal set the stage for a high-stakes investigation with global implications.

At Castlemartin Manor-a decaying stronghold for a once-cutting-edge surveillance program-Ethan is forced to navigate shifting loyalties, encrypted legacies, and the labyrinthine politics of modern intelligence. As the storm outside intensifies, so does the war within: between faith and cynicism, memory and manipulation, human judgment and machine prediction.

Gripping, intelligent, and hauntingly prescient, A Spy Inside the Castle explores the intersection of technology and truth in an age where perception is weaponized-and no one is beyond suspicion.

Although the actual book is ok, I found narrators voice monotonous, which made it difficult to follow and keep me engaged.
