The novel is the story of Dreyer, a wealthy and boisterous proprietor of a men's clothing emporium. Ruddy, self-satisfied, and thoroughly masculine, he is perfectly repugnant to his exquisite but cold middle-class wife Martha. Attracted to his money but repelled by his oblivious passion, she longs for their nephew instead, the myopic Franz. Newly arrived in Berlin, Franz soon repays his uncle's condescension in his aunt's bed.
