Long before their country officially joined the war, American aid workers were active in rescue efforts across Europe. Two such Americans were Martha and Waitstill Sharp, who were originally sent to Prague as part of a relief effort but turned immediately to helping Jews and dissidents after the 1939 invasion by Germany. They were not the only ones. Renowned historian Deborah Dwork follows the story of rescue workers in five major cities as the refugee crisis expanded to Vilna, Shanghai, Marseille, and Lisbon. Followed by Nazi agents, spiriting people across borders, they learned secrecy. Others negotiated with government representatives, like Laura Margolis, who worked with the Japanese, to get enough food and warm shelter for the refugees in Shanghai. Yet, the women also often faced lack of support from their agencies; if part of a couple, they fought to get paid even at a low salary despite working as long and hard as their husbands. Moving and revelatory, Saints and Liars illuminates the unpredictable circumstances with which these aid workers contended, while revealing the moral questions they encountered and the devastating decisions they had to make.
