About this episode

This episode explores the life of Harold Derber, a British Merchant Navy veteran who became a pioneer in the modern drug trade.

In this episode of the Mariner’s Mirror podcast, we explore the extraordinary life of Harold Derber — a British Merchant Navy veteran whose early training as a wireless operator during the Second World War set him on an unexpected and remarkable path. From the dangers of Atlantic convoys to the political turbulence of the Cold War, Derber’s story moves far beyond the bridge of a ship. Derber would go on to become one of the pioneers of the modern drug trade, developing the concept of the “drug mothership” and operating a ghost fleet that supplied hundreds of tons of marijuana to post-war America. His journey took him from humble beginnings in Manchester to a violent end on the streets of Miami. To uncover this fascinating story linking maritime history and true crime, Dr Sam Willis spoke with author David Tuch , whose debut book The Wireless Operator investigates Derber’s life in remarkable detail. Tuch also has a personal connection to the story — he is a descendant of the elusive smuggler himself. Hosted on Acast. See acast.com/privacy for more information.
