One of the real life persons whose escape is depicted in this enthralling series is a young Hannah Arendt. After safe arrival in the US she became an historian and philosopher. Her books. On Totalitarianism, The Human Condition, and On Violence were part of the required readings for the 3rd and 4th year Political Science courses I took in the 1970's. Still have one of her books in my personal library. Her voice may have never been heard if the dedicated people portrayed in the story had been stopped, or worse still, chosen to do nothing
