The first comprehesive account of the work of the Security Section of the Special Operations Executive (SOE) during the Second World War, Security and Special Operations makes extensive use of recently declassified files and oral testimony in order to tell the story of the Section, which ran SOE's facility at Inverlair where failed recruits were held. It considers SOE's security arrangements overseas at its Misssions in Egypt, Italy and India, and goes on to examine the development of liaison between SOE and MI5, which was conducted through the Security Section, detailing the attempts made by MI5 to use 'blown' SOE agents in its double cross operations and offering a fresh perspective on both the 'Englandspiel' disaster in Holland and the case of the notorious agent Henri Dericourt.
