The disturbing story of how the Nazi's infiltrated the heart of the Allied special forces operations during World War Two. Perfect for fans of Helen Fry, Maurice Buckmaster or Ben MacIntyre's SAS: Rogue Heroes.

Known as "Churchill's Secret Army" the Special Operations Executive conducted espionage, sabotage, and reconnaissance missions as well as aiding local resistance forces in occupied Europe. This secret force was comprised of over 13,000 men and women, but could they all be trusted?

Through the course of the war when agents went mysteriously missing, promising missions failed catastrophically and whole resistance forces were wiped out, questions began to arise. Perhaps these disasters were not simply bad luck, but instead there were traitors working to bring down the SOE from within.

The German Penetration of SOE reveals how the Nazis enticed and co-ordinated with double-agents, how they impersonated captured agents and deceived the Allies into parachuting operatives into ambushes.

Jean Overton Fuller's meticulous research uncovers, layer by layer, the dark world of espionage and counter-espionage in the Second World War. Utilising not only documentary evidence but also interviews with Allied and German operatives and double-agents she has been unable to shed light onto how the Nazis penetrated into the core of the SOE.
