The first chapters of the novel deal with Fabian's confrontation with the immorality of Berlin nightlife; he visits brothels, underworld taverns, and artists' studios.

He is inadvertently drawn into the increasing political polarisation between National Socialists and Communists, and witnesses Berliners engaging in unrestrained sexual hedonism to the exclusion of genuine love.

In an artist's studio, Fabian meets Cornelia Battenberg, who has sworn off relationships after having had negative experiences with men in the past.

The relationship has a great impact on Fabian, causing him to develop ambition and seemingly abandon his pessimistic worldview.

The script was never refused, and the rejection letter Labude received was a malevolent prank played on him by his doctoral advisor's assistant.
