Also known as Jack, Whereupon Jack
First appearance: The Coral Island
As a major figure in The Coral Island, Jack Martin is not background color—the story leans on what they do once the chapter opens.
Practical and resourceful; takes the lead in building shelter and organizing tasks.
Jack is Ralph's first friend aboard ship and the eldest of the three boys, a general favourite whose firm, good-humoured face and quiet disposition mask decisive action. He takes charge without fuss, whether showing a new messmate his berth or sizing up a black flag on the horizon, and his calm is the counterweight to Peterkin's mischief and Ralph's wonder. The island's early survival—and the boys' first taste of real danger—rests on his judgment.
