In Paris around the 1840s, Lisbeth Fischer, known as Cousin Bette, is a poor, plain relative who lives among her more successful family. Bitter and watchful, she nurses old jealousies and quietly plots against those who have wronged her. Around her are the vain Baron Hulot, whose appetites threaten his household, and the young artist she once befriended. The novel is a dark, sharp portrait of envy, desire and money, showing how private passions can unsettle an entire family.
