"Impossibly good luck!" says Parthian King, reading over Lady Em's shoulder. "An overland map to the pirate's hideout! That must have been inadvertant!"
"Or a trick," says Lady Em. "How could they have been so careless as to let their position go with such ease? Besides, this note mocking us makes my blood boil!"
"Oh, pirates and bottles, bottles and pirates--you know," says Parthian King. "They probably put the map in there by accident. In any case, it cannot be ignored. As long as they come by sea, we are on the defensive. Even if we had the ships, there's no using my cavalry against them at sea, and we Parthians have this thing about water..."
"What thing?" says Prince of the West, approaching from behind.
"We don't like it," says Parthian King.
"Oh," says the Prince.
"Anyway, this changes everything! It means we can go after them!" *Parthian King grins and rubs hands together* "At last, by the Lion's mane we shall see what a coordinated attack shall really look like! Flush the worm from its hole, I say!"
