Becky Sharp says farewell to the Sedley family and enters the service of the crude and profligate baronet Sir Pitt Crawley, who has engaged her as a governess to his daughters. Her behaviour at Sir Pitt's house gains his favour, and after the premature death of his second wife, he proposes marriage to her. However, he finds that she has secretly married his second son, Captain Rawdon Crawley, but Becky very much regrets having done this as she had no idea that his father's wife would die so soon after. Sir Pitt's elder half sister, the spinster Miss Crawley, is very rich, having inherited her mother's fortune, and the whole Crawley family compete for her favour so she will bequeath them her wealth. Initially her favourite is Rawdon Crawley, but his marriage with Becky enrages her. First she favours the family of Sir Pitt's brother, but when she dies, she has left her money to Sir Pitt's oldest son, also called Pitt.
