While Twain and Higbie look for water that is supposed to be on the island, the weather turns cloudy. They decide to check on their boat that they did not tie up because the weather was good. They are now back where they left the boat, but the boat is gone. They are alone on an island in the middle of Mono Lake and no one knows they are here. Will they live without water? Will Twain die and not write "Tom Sawyer" and "Huck Finn?" Where did the boat go?
