Purnell meticulously researched the book, scouring archives for long lost documents, reading correspondence, and interviewing Virginia’s niece. The narrative is dense, full of timelines, facts, and the names and code names of Virginia’s operatives, who were often to her great frustration ill-suited to the work and reckless, putting herself and others at great risk. The book reads like an adventure story, and Virginia’s winning personality, charm, ability to change her appearance – and most of all her complete fearlessness – left an indelible mark on the course of history. Following the war, Virginia was one of the first females hired by the newly formed Central Intelligence Agency.
