Peter Demetz is the last witness of a city that, like no other, represented the fruitful coexistence of various European cultures for centuries. Germans, Czechs, and Jews shared a tumultuous common history in Prague, which came to a definitive end with Hitler. Peter Demetz has now dedicated a significant memoir to the period of German occupation between 1939 and 1945, the darkest years he spent in his hometown, shedding unique light on a transformative era of European history.
