Summary
In the beginning Jack is in a Tortuga tavern, looking for his satchel, which has been stolen. He thinks he has found it under the seat of a notorious pirate Torrents, who catches Jack stealing. In the ensuing bar fight, Jack slips out, only to find out that the satchel isn't his. This one contains, among various personal items, the magical sheath for the Sword of Cortés. The barmaid, Arabella Smith, who pulled Jack out of the fight, makes this discovery with him. They plan together to a ship to go look for the storied Sword of Cortés, and reunite it with its sheath. Arabella directs Jack to an abandoned ship, the Barnacle. Before they leave Tortuga, a strong young boy, Fitzwilliam P. Dalton III, insists on joining them for their quest. The three sail for many days and come upon an island, where they meet two twelve year old boys, Jean and n, and Jean's cat-turned-sister Constance. Jack remarks about The Sword of Cortés, and Jean and Tumen lead the crew to a 'dead' city on the cursed island. Inside the main building of the city, the crew find the skeleton of the city's king, Stone-Eyed Sam, who is said to be holding the Sword, but it is missing. Jack pockets the fabled stone eye of the now-dead former pirate king as a souvenir. The crew find left footprints on the ground, and soon realize that the notorious pirate, Left Foot Louis, has it. They all go rushing to the Barnacle, when they suddenly come face to face with Torrents, a crew member of the feared Davy Jones's crew. They all battle on the beach, for who would get the Sword of Cortés's sheath, and Jack eventually defeats Torrents and escape on the Barnacle. jomar cute
