They sail for New York to learn the whereabouts of Kidd, and posing as ordinary seamen, they join his crew. They learn that Kidd, the legendary swashbuckler of the seven seas, is not a a villain who scourges and plunders at will, but a man whose loyalty to England knows no bounds, a maritime adventurer who attacks only enemy French vessels and those of the pirates that sail against the British Empire.
