The British censorship station at Bermuda, December 1940.
An intercepted letter, giving details of allied shipping in New York harbour, signed, innocently enough, 'Joe.'
The actions of an alert censor, and tests carried out on the letter in the censorship laboratories, confirmed British suspicions that 'Joe' was a member of a German spy ring working in the United States. Both the British and the Americans were anxious to break the ring. But first, they needed to establish the identity of 'Joe.'
