A wealthy Serbian playboy throwing down massive bets at a Portuguese casino, secretly funded by German intelligence while working for the British, caught the eye of a young naval officer named Ian Fleming. This episode tells the real story of Dusko Popov, the World War II double agent who inspired James Bond, fed Germany false D-Day intelligence, and tried to warn the FBI about Pearl Harbor months before the attack.

We trace Popov’s rebellious origins, his Gestapo arrest and rescue by friend Johnny Jebsen, and his recruitment into the British double-cross system under the code name Tricycle. We examine how chicken-feed intelligence built his credibility, the tragic cost of Jebsen’s sacrifice, and the catastrophic personality clash with J. Edgar Hoover that buried a Pearl Harbor warning.

• The three-page questionnaire devoting a full page to Pearl Harbor’s defenses
• Why Hoover threatened to arrest Popov under the Mann Act and ignored his warning
• Popov’s role in Operation Fortitude and the Calais deception confirmed by Lorenz decrypts
• How the real spy differed from the polished myth, debts, embellishments, and all
