Berlin Alexanderplatz by Alfred Döblin (1929). Franz Biberkopf, an ex-convict, becomes entangled with a criminal gang led by Reinhold, who attempts to manipulate Franz into criminal activities, framing it as a mutually beneficial arrangement. Franz initially tries to assert his autonomy, but Reinhold’s manipulative, transactional approach overwhelms him. The emphasis on reciprocal obligations and maintaining one’s word, even in criminal dealings, underscores the cultural weight given to agreements and commitments in German culture.
