The Walls Have Ears

[A] remarkable book -Nick Rennison, Daily Mail (Book Of The Week) Interesting, informative, enlightening - All About History This is a great book and a valuable contribution to scholarship on the Second World War - Michael Goodman, BBC History Magazine The world has long been familiar with Bletchley Park, where German codes were cracked by a secret army of listeners intercepting enemy wireless transmissions. But now, another clandestine intelligence operation that played an equally important part in the war has come to light. -Tony Rennell, Daily Mail (War Books of the Year) Quite brilliantly tells of the intelligence bonanza gained from bugging the rooms where captured Nazi generals were held as they let their tongues wag -Gerald Seymour, Daily Express 'Best Books of 2020' A fascinating, well-researched glimpse into a hitherto neglected corner of the intelligence history of the Second World War. -Nigel West, author of Double Cross in Cairo Fry shines a revealing light into a dark and forgotten corner of the British wartime intelligence effort, with truly remarkable results. -Mark Felton, author of Operation Swallow Fry has uncovered an astonishing story of wartime espionage, featuring prisoners of war, microphones hidden in vegetation and interrogations so subtle that the subjects never realised what was happening. Almost as amazing as the operation itself is that it stayed secret so long. -Robert Hutton, author of Agent Jack Fry traces the development and growing sophistication of interrogation technique during the Second World War, the overlay of apparent British eccentricity and creative deception on a determined intelligence operation ... Fascinating. -Michael Jago, author of The Man Who Was George Smiley
