Moll's mother is a convict in Newgate Prison in London who is given a reprieve by "pleading her belly," a reference to the custom of staying the executions of pregnant criminals. Her mother is eventually transported to Colonial United States, and Moll Flanders (not her birth name, she emphasises, taking care not to reveal it) is raised from the age of three until adolescence by a kindly foster mother. Thereafter she gets attached to a household as a servant where she is loved by both sons, the elder of whom convinces her to "act like they were married" in bed. Unwilling to marry her, he persuades her to marry his younger brother. After five years of marriage, she then is widowed, leaves her children in the care of in-laws, and begins honing the skill of passing herself off as a fortuned widow to attract a man who will marry her and provide her with security.The first time she does this, her "gentleman-tradesman" spendthrift husband goes bankrupt and flees to the Continent, leaving her on her own with his blessing to do the best she can to forget him. (They had one child together, but "it was buried.") The second time, she makes a match that leads her to Virginia Colony with a kindly man who introduces her to his mother. After three children (one dies), Moll learns that her mother-in-law is actually her biological mother, which makes her husband her half-brother. She dissolves their marriage and after continuing to live with her brother for three years, travels back to England, leaving her two children behind, and goes to live in Bath to seek a new husband.Again she returns to her con skills and develops a relationship with a man in Bath whose wife is elsewhere confined due to insanity. Their relationship is at first platonic, but eventually develops into Moll becoming something of a "kept woman" in Hammersmith, London. They have three children (one lives), but after a severe illness he repents, breaks off the arrangement, and commits to his wife. However, he assures Moll that their son will be well cared for, so she leaves yet another child behind.Moll, now 42, resorts to another beau, a bank clerk, who while still married to an adulterous wife (a "whore"), proposes to Moll after she entrusts him with her financial holdings. While waiting for the banker to divorce, Moll pretends to have a great fortune to attract another wealthy husband Lancashire, assisted by a new female acquaintance who attests to Moll's (erroneous) social standing. The ruse is successful and she marries a supposedly rich man who claims to own property in Ireland. They each quickly realise that they were both conned and manipulated by the before mentioned new acquaintance.
