The Secret Listeners: How the Wartime Y Service Intercepted the Secret German Codes for Bletchley Park

Follow-up to the bestselling The Secret Life of Bletchley Park, the hitherto-untold story of how young men and women across the world listened in to and intercepted the enemy’s radio traffic so that Bletchley Park’s codebreakers could turn the course of the war. Before Bletchley Park could break the German war machine’s codes, its daily military communications had to be monitored and recorded by “the Listening Service” – the wartime department whose bases moved with every theatre of war: Cairo, Malta, Gibraltar, Iraq, Cyprus, as well as having listening stations along the eastern coast of Britain to intercept radio traffic in the European theatre. This is the story of the – usually very young – men and women sent out to far-flung outposts to listen in for Bletchley Park, an oral history of exotic locations and ordinary lives turned upside down by a sudden remote posting – the heady nightlife of Cairo, filing-cabinets full of snakes in North Africa, and flights out to Delhi by luxurious flying boat.
