Peter Duck : (based on information supplied by the Swallows and Amazons and illustrated mainly by themselves)

The Swallows and Amazons are sailing with Nancy and Peggy's Uncle Jim (better known as Captain Flint) when their hired deckhand tells them a tale of his younger days - a tale to set pulses racing and hopes shooting sky high.

Soon their boat is on its way to a Caribbean treasure hunt and they find themselves up against shark, storm, earthquake - and the vilest pirate who ever eavesdropped at a porthole.
