How did the Special Operations Executive (SOE) function as a clandestine instrument of warfare during the Second World War? Mark Seaman, a former historian at the Imperial War Museum, examines the organizational structure, strategic objectives, and operational challenges of the British organization tasked with sabotage and subversion in occupied territories. The book utilizes declassified archives and official records to analyze the tension between conventional military doctrine and the unconventional methods required for resistance support.

Historians and military scholars recognize this work as a comprehensive and well-documented account of the SOE's complex history. Readers frequently note the academic rigor of the prose, which provides a balanced view of both the successes and the systemic failures of the organization.
