What if the most pivotal spy of World War II never carried a gun, never wore a uniform—and never told a soul?
Buried beneath the headlines of history lies a story so gripping, so unexpected, and so meticulously hidden that even the most seasoned espionage readers will be stunned. The Secret Invisible Spy rips back the curtain on America’s first covert intelligence war—one fought not on the battlefields of Europe, but in the corridors of Rockefeller Center, the smoky backrooms of Washington, and the airwaves of a nation on edge.
He was a lawyer. A football player. A media insider. And secretly, the most trusted liaison between Roosevelt and Churchill’s undercover operatives.
Meet Ernest Cuneo—the forgotten American behind the biggest British spy operation ever conducted on U.S. soil. While Hitler’s agents crept into America’s cities, Cuneo worked in the shadows—coordinating sabotage prevention, suppressing Nazi propaganda, and passing classified intelligence between the Oval Office and London’s top spymasters. His life intersected with Ian Fleming, Walter Winchell, J. Edgar Hoover—and a brilliant female agent nearly killed for knowing too much.
Yet his name never made the history books. Until now.
