Hans Fallada (who's name was Rudolf Ditzen and there's a Rudolf-Ditzen-Weg at the Majakowskiring in Pankow) wrote Every man dies alone (Jeder stirbt für sich allein also known as Alone in Berlin) as novel based on the life of two people who fight back the Nazis alone in Berlin in their own way and they end up in the Plötzensee prison.
A long time ago I've got a night vision of Berlin as an empty city, with its monuments and lights, but far from the collective imagination and stereotype of its nightlife, of people drinking, music and noise.
There's another city there outside, just close to this one, made of silence, of palpable intensity, made of light, where "every man dies alone".
