In the wake of WWII, 4 agents were critical in helping build a new organisation now known as the CIA. Adelaide Hawkins, Mary Hutchison, Eloise Page, and Elizabeth Sudmeier, called the 'wise gals' by their male colleagues, were smart, courageous, and groundbreaking agents at the top of their class, instrumental in both developing innovative tools for intelligence gathering – and insisting (in their own unique ways) that they receive the credit and pay their expertise deserved. Meticulously researched and beautifully told, Holt uses firsthand interviews with past and present officials and declassified government documents to uncover the stories of these four inspirational women. This book sheds a light on the untold history of the women whose daring foreign intrigues, domestic persistence, and fighting spirit have been and continue to be instrumental to the world's security.
