By the end of the chapter, real trouble for the king and duke has come with the arrival of the legitimate heirs. It seems a confrontation will soon follow.
Chapter 29 Summary: To make a long story short, there's a lengthy dispute between the two pairs of heirs. As time passes, however, it becomes increasingly clear that the king and duke are frauds. All of the tension comes to a fountainhead at the burial of Peter Wilks, where the gold is discovered.
Leaving the king and duke to pay the penalty for their fraudulent scheming, Huck breaks free from the group and runs back to the river, where Jim has been waiting for him. Unfortunately, the king and duke follow him to the raft, angry that Huck was trying to give them the slip."
Chapter 30 Summary: So the foursome continues its journey down river, free from the town, but with the king and duke's scheme utterly foiled. Taking the pressure off of Huck for a moment, the king and duke argue amongst themselves, now suspecting each other of betrayal.
Chapter 31 Summary: After traveling south for a few days now, the schemers begin to plot secretly. Huck becomes nervous. Coming back to the raft a few hours later, he realizes that Jim is gone, and suspects that the king and duke have sold him back into slavery. He quickly learns from a boy from the town that Jim has been brought to Phelps farm, which is nearby. Huck returns to the wigwam to think, considering whether or not to send a letter to Miss Watson telling her Jim's whereabouts. He ultimately decides against this, believing he will be the laughing stock of the town for helping a slave escape. He also considers how wicked he has become, thinking that he must be surely damned for such actions. He accepts this fate, however, believing that he's going to hell anyway so he might as well help his friend, Jim. Thus, Huck begins to walk towards the Phelps' farm. On the way, however, he encounters the duke, who is putting up a flyer for another Royal Nonesuch performance. The duke blames the king for selling Jim, saying that he took all the money for himself. He tells Huck that Jim is forty miles away, making up a story to get rid of the boy. Of course Huck realizes that he's being lied to, but he pretends to follow the duke's advice, starting off right away towards the place the duke has directed him. Once out of sight, however, Huck heads directly towards the Phelps' house.
