Set among urban bourgeois households, the novel traces how a comfortable marriage’s routine is upended when a charismatic relative rekindles desire and temptation. The wife’s quiet discontent and the cousin’s seductive advances lead to a clandestine liaison that lays bare private vanities, domestic fragility, and social duplicity. Through close psychological observation and satirical sketches of manners, the narrative follows the ripple effects of the affair—gossip, manipulation, and moral entanglement—while probing themes of passion, hypocrisy, and the fragile boundaries between respectability and transgression.
