The Spy Hunters: How Counterintelligence Caught History's Most Dangerous Spies

Every spy in this book thought they were invisible. Every single one was wrong.From the Tower of London in 1914 to a Virginia park in 2001, The Spy Hunters reveals how eleven of history's most dangerous intelligence operations were built, run, and ultimately exposed. Not through luck. Not through heroics. Through the one thing no spy can fully control: the residue they leave behind.A letter sent without a cipher. A financial record that didn't add up. A fingerprint on a reused bag. Patterns in the data that the spies themselves never saw coming.This is the true history of counterintelligence. Not the glamour. Not the gadgets. The real thing: the patient, methodical, often brutal art of reading what people leave behind when they think no one is looking.
