You are now listening to World War 2 Stories. I'm your host Steve Matthews. Today, we explore one of the most devastating intelligence failures of the Second World War—a meticulously crafted deception operation that crippled British espionage networks across Europe and revealed the frightening sophistication of Nazi counterintelligence. This is the story of the Venlo Incident.

In the misty twilight of November 9, 1939, two British intelligence officers sat nervously in their car near the Dutch-German border, waiting for a meeting they believed might change the course of the war. Captain Sigismund Payne Best and Major Richard Stevens were experienced spies who thought they were about to make contact with high-ranking German military officers plotting to overthrow Adolf Hitler. Instead, they were minutes away from walking into a trap that would destroy years of careful intelligence work and condemn them to five years in Nazi concentration camps.

What happened at Venlo stands as one of the most consequential intelligence disasters in modern history—a perfect storm of miscalculation, desperation, and sophisticated enemy deception that offers timeless lessons about the perils of espionage and the dangers of believing what you desperately want to be true.
