Plot Summary
Chapter 20 begins with Huck spinning a cover story for the duke and the king, explaining that he and Jim travel at night because people keep trying to seize Jim as a runaway slave. The duke promises to devise a scheme that will allow them to travel by day. That night, the group passes a riverside town under cover of darkness and continues downstream through a spectacular thunderstorm. Huck gives a vivid account of the lightning, crashing thunder, and waves that nearly wash him off the raft, while Jim generously takes the first half of Huck's watch so he can rest.
The next morning, the duke and king begin planning money-making schemes. The duke reveals his past careers—phrenologist, Shakespearean actor, water-witch, and more—and proposes they perform the sword fight from Richard III and the balcony scene from Romeo and Juliet. He assigns the king the role of Juliet, dismissing concerns about the king's age and bald head. They rehearse on the raft before approaching a small town where everyone has gone to a camp meeting two miles back in the woods.
The king attends the camp meeting and launches an audacious con. He takes to the platform, tearfully claims to be a reformed pirate from the Indian Ocean, and says he wants to return there to convert his fellow pirates to righteousness. Moved by his performance, the congregation takes up a collection that nets him eighty-seven dollars and seventy-five cents, plus a jug of whisky he steals on the way out. Meanwhile, the duke takes over the deserted printing office, earns money from horse-bill jobs, newspaper advertisements, and advance subscriptions, totaling nine dollars and fifty cents. More importantly, the duke prints a fake handbill describing Jim as a runaway slave worth a 00 reward, so they can travel openly by tying Jim up and claiming they are returning him for the bounty.
Character Development
This chapter deepens the characterization of both the duke and the king as resourceful but morally bankrupt grifters. The king's camp-meeting swindle reveals his talent for emotional manipulation and religious hypocrisy, while the duke's printing-office exploits demonstrate a quieter but equally calculating cunning. Jim continues to show his selfless nature, volunteering to take Huck's watch during the storm, yet the chapter closes with Jim's shrewd observation that the king is "powerful drunk" and the duke not much better—showing that Jim sees through their pretenses even as he remains powerless to resist them. Huck, meanwhile, acts as both observer and reluctant accomplice, narrating the con men's schemes with a mix of admiration and unease.
Themes and Motifs
The chapter explores the theme of deception and gullibility, contrasting the con artists' calculated lies with the camp-meeting crowd's eager credulity. Religion is satirized as the pious congregation is easily manipulated by the king's theatrical repentance. The motif of identity and disguise recurs as both the duke and king adopt false identities for profit, and the fake handbill transforms Jim's status from a person into a piece of paper worth two hundred dollars. The raft vs. shore dichotomy intensifies: the shore brings fraud and exploitation, while the raft remains a space where Jim and Huck share genuine loyalty.
Literary Devices
Twain employs satire to lampoon both the camp-meeting revivalism and the grifters who exploit it. The thunderstorm sequence uses vivid onomatopoeia—"h-wack! bum! bum! bumble-umble-um-bum-bum-bum-bum"—and imagery to create one of the novel's most memorable nature passages. Dramatic irony pervades the camp-meeting scene, as readers understand the king's true motives while the congregation does not. The duke's fake handbill is a powerful piece of situational irony: a document designed to protect Jim simultaneously reinforces the very system of slavery that threatens him. Twain's vernacular dialogue continues to distinguish each character, from Huck's measured narration to Jim's closing observation in dialect.
