In Berlin they see each other frequently (including eating ham and eggs at the first class restaurant of Berlin Friedrichstraße railway station). Several oddities of Mr Norris's personal life are revealed, one of which is that he is a masochist. Another is that he is a communist, which is dangerous in Hitler-era Germany. Other aspects of Mr Norris's personal life remain mysterious. He seems to run a business with an assistant Schmidt, who tyrannises him. Norris gets into more and more straitened circumstances and has to leave Berlin.
