A pioneering investigation into the secret world of wartime Persia (Iran), meticulously sourced and based on six years of extraordinarily wide and deep research in the German, British, and American archives. This study exposes the problems, pressures, and personalities among the competing German intelligence services that targeted Persia, and it describes the highly effective methods employed by the implacable Allied security forces that resisted them. It tells a riveting tale: there are parachutists, gold, guns, dynamite, double agents, mistresses, and Byzantine intrigues galore in this compelling historical narrative. At the same time, as a serious academic study and a penetrating analysis of catastrophic intelligence failure, Adrian O’Sullivan’s book is a highly significant contribution to Second World War intelligence history.
