What does the king's conversation on the steamboat foreshadow?

The whole town is awaiting the arrival of Peter Wilks' brothers. Wilks recently died, and has quite a bit of money to leave his family. The King's conversation on the boat begins with him saying he isn't the Wilk's brother, but soon after he finds out that they have no idea when the brothers will be arriving, that no one has any idea what they look like, and that Mr. Wilks hasn't left a will, only a letter telling where his money is hidden. Foreshadowing; they're going to pretend to be the dead man's brothers and find out where the money is so they can steal it!
