Plot
Charlie Chan is engaged by an heir to solve a mystery on a boat. Miss Nodbury seeks a pirate treasure on Cocos Island, and her ship has recently hosted a museum of pirate lore. For safety, she has split her map into four pieces, which she gave to some of the passengers whom she has invited, but tells no one who they are. When she is given a fright and succumbs to her heart disease, Chan must clear up the mystery while the ship is still at the dock.
