Mary Lindell, the Comtesse de Milleville, was British-born but a largely forgotten agent. She combined a passion for adventure with blunt speech and persistently displayed the greatest personal bravery. The Germans denied that American or British prisoners were imprisoned in Ravensbrck, but Lindell smuggled out a secretly compiled list that detailed women who were agents of British Military Intelligence, Special Operations Executive (SOE), or the French Resistance. Lindell's List details their survival and rescue under Mary's heroic leadership. The work includes first-person testimony that has never been published before.
