Jonathan is free and fourteen, with a man's courage. He had joined the Patriot's army to fight, not just to be an errand boy for a ship's captain. But as he waits in disgust for the boat to arrive at midnight, he suddenly sees a dead man lying in the water. And from the shadows springs another man, who knocks Jonathan unconsious. Too late, Jonathan realizes he's in a deadly business - with unknown spies on the Devil's Belt!
