Frederick Rutland was one of Britain's finest naval pilots and a celebrated hero of the First World War. And yet in the interwar period, he would become a turncoat, feeding information to Japanese intelligence whilst living undercover in the glitz and glamour of 1930s Hollywood.

Joining Dan to discuss Rutland's life is Ronald Drabkin, author of 'Beverly Hills Spy: The Double-Agent War Hero Who Helped Japan Attack Pearl Harbor'. Ron explains how his information helped the Japanese to build a cutting-edge navy, and how he managed to evade capture by American and British intelligence.

Produced by James Hickmann and edited by Dougal Patmore.
