Cato Bontjes van Beek lives here. At twenty, she is among the youngest members of Rittmeister Kreis. Her ambition is to be a pilot. A sprinkling of freckles dot her nose and cheeks. Before joining Rittmeister Kreis, Cato smuggled food to Jews in hiding. One day she watched SS officers drag her Jewish neighbors—a young mother, father, and their five-year-old son—out of their apartment. She never saw them again.
