- Hi. How'd you make out?

- Fine. Much better than we'd expected. Thank you.

- That's good. No problem, then?

- I wish that were true.

- We still have another $38,000 to give Mr. Seymour before the first of the month.

- Why is Seymour so anxious to get his hands on this property, anyway?

- Here, I'll show you on the map. You see, this is the island we're on.

- In Blackbeard's time, the river flowed this way, and the inn wasn't on the island at all, it was part of the mainland.

- Then, about 80 years ago, we had this terrible flood and a storm and the river changed its course, isolating the inn from the mainland.

- As a result, nobody's ever been able to clarify what the legal jurisdiction of the island really is.

- That's where Mr. Seymour comes in?

- Sure. He can tear down the inn, put up a big, modern casino, and the law can't bother him.
