"I have a map to riches beyond measure." Lord Farnsworth spoke, sipping his Malmsey.
"Where?" requested Lord Plunk.
"Some five hundred miles up the Amazon lay the ruins of a temple, unspoilt, for only I have the original map of Francisco de Orellana."
"Bah...humbug. All we shall find is disease, filth, and hostiles. A map? Indeed?"
"Have you a better expedition, Milord?"
"Yes, with no ocean to cross."
"Go on."
"A cave at Peloponnese, entrance to the river Styx of the Underworld and beyond."
"A known cavern and no entrance ever found. What gives you surety?"
"I have a map."
