David Copperfield is a tale of two loves. When young David goes to school in Canterbury, he is taken into the hospitable home of Mr Wickfield, a lawyer running a rich gentleman's estate. There he meets Wickfield's daughter Agnes, who is about the same age as himself and who captivates him with her lovely face and composed manner. He quietly observes the tact with which Agnes treats her father who, after his wife's death, has started to drink more than is good for him. Unfortunately she cannot prevent his practice from going into a steep decline, and Uriah Heep, Wickfield's crafty clerk, is able to force her father to make him a partner. When David continues his education in London, he often seeks Agnes's advice, revelling in her wisdom and affection.

In London David is articled to Mr Spenlow. At a dinner he is introduced to Spenlow's daughter Dora. It is love at first sight: he loses his heart and perhaps a little of his good sense as well. Dora is in many respects the very opposite of Agnes. She is a ‘child wife’, playful and flighty, but also capricious and easily upset. Against his great-aunt's advice he marries Dora. The marriage is idyllic in the beginning, but it gradually becomes clear that David cannot really count on her support.
