The Codebreakers: 6: Message to Moscow

BBC Two
on BBC Two England

Presented by Rene Cutforth

Saturday evening, 7 January 1961. Supt Smith of Scotland Yard arrests the Krogers at their Ruislip bungalow. The Portland Spy Ring is broken.
The Krogers were probably the most capable spies ever caught. Their coding and communications techniques were models of efficiency and security. But how did their sophisticated devices work? The innocent-looking talc tin and whisky flask? The transmitter with the high-speed keying device? The one-time code pads? The microdots?
