The more Martha came to know Diels, the more she saw that he too was afraid. He felt “he was constantly facing the muzzle of a gun,” she wrote. He was most at ease during their drives, when no one could overhear their conversations or monitor their behavior. They would stop and walk through forests and have coffee in remote, little-known cafés. He told her stories of how everyone in the Nazi hierarchy distrusted everyone else, how Göring and Goebbels loathed each other and spied on each other, how both spied on Diels, and how Diels and his men spied on them in turn.
