Treasure Island

Aye, mateys, let me tell you a story that'll warm the cockles of your hearts. It began at the Admiral Benbow Inn, where young Jim Hawkins and his mother were eking out a living as innkeepers. The problem was, no one ever seemed to stop there--until one shivery day, when a man named Billy Bones arrived.
Bones told Jim,

"Now, if you notice a seaman hanging about with only one leg, you come and tell me straight away, and I'll give you a silver penny. Do we have a bargain?"

Jim, who was trying to save money for college, eagerly agreed.

"Yes, sir. I'll keep a sharp watch."
