On 7th December, 1941, the Japanese Imperial Navy struck the United States. In an action which killed 2,403 Americans and destroyed 21 US warships and 188 aircraft, they also brought the US into the Second World War.

But it may not have been possible without the input of a British spy who had, for a time, lived in Hollywood, mingling with stars of the screen. So who was Frederick Rutland? What information did he give the Japanese Navy intelligence that might have helped them launch the attack on Pearl Harbor? And why did he give it to them?

Ronald Drabkin, author of 'Beverly Hills Spy: The Double-Agent War Hero Who Helped Japan Attack Pearl Harbor', joins Don for this episode. Together, they discuss Rutland's life and impact, and just how the intelligence services failed to catch him for so long.

Produced by Sophie Gee. Edited by Aidan Lonergan. Senior Producer was Charlotte Long.
