The first thing Huck tells us about the people in town is that Mary Jane, the oldest of the nieces, is beautiful. And a redhead.
The nieces fall for the plot hook, line, and sinker, thanks to all the info that the king got from the young man he met earlier.
They embrace the duke and king as their long-absent uncles.
Huck thinks it's disgusting the way the duke and king kneel and pray over the dead body, pretending to be distraught.
Then they get to the business of the will; Peter allotted $3,000 and the house to the three nieces, and another three thousand and other property (worth seven grand) to his brothers.
The two conmen go down into the cellar where the six thousand in gold is hidden. They're all Scrooge-McDuck-excited and get to counting it right away.
The money ends up being short: it's not quite six thousand as it should be. Actually, it's $415 short.
The cons are worried that the townsfolk will start to get suspicious if money is missing; they might think the brothers stole it. So the duke suggests making up the deficit using their own money (the profits from The Royal Nonesuch).
We're getting a good whiff of foreshadowing right here.
The duke decides it would be even more impressively magnanimous of them to go upstairs and publicly give all $6,000 to the girls.
The king does so, but being the king, of course, he has to couch the presentation in all sorts of pomp and circumstance.
One little problem: the king doesn't actually know much about pomp. Like, he keeps referring to the "funeral orgies" they're going to hold the next day.
The duke, who is apparently less of a fool than the king, keeps trying to get his attention and tell him that, actually, the word is "obsequies."
The king then has to publicly explain to the world that "orgies" is the British term.
Everyone is all, "Oh, OK," except for one particularly not-stupid man, a doctor named Robinson, who acts quite the skeptic.
Actually, he directly calls the king a fraud with "the worst imitation" of a British accent he's ever heard (25.40).
No one likes a skeptic, and the townspeople rally behind the cons.
To prove her faith in the two men, Mary Jane gives them back the $6,000 back and says she doesn't even want a receipt.
