Rome: the 1930s, and the Italian secret services were having extraordinary success in reading the messages sent by rival countries’ diplomats from their embassies in the ‘Eternal City’.

With the road to World War Two still ahead, it was a time of significant geo-political tension. The Italian government was learning the secrets of countries such as Britain and France in order to gain an advantage in international affairs. This would continue after Italy joined the war in 1940, with substantial consequences for the campaign in North Africa.

In this episode, we will hear how the Italians didn’t succeed by using mathematicians or intellectuals, but with a rather more direct approach. David Kenyon, Bletchley Park’s Research Historian, joins podcast producer Mark Cotton to reveal more.

Our thanks go to Dr Ben Thompson for voicing our historical documents.
