Plotting in Pirate Seas

he boy hunted for some wild fruit to stay his appetite--he had nothing to eat since the night before--and settled down for the rest of the afternoon to try and dig out the meaning of his father's papers, some of which seemed so clear, while to others he had no clew. It was characteristic of the boy that, once this idea of menace to the United States had got into his head, the thought of personal danger never crossed his mind. The slightly built boy, small even for his age, the first sight of whom would have suggested a serious high-school student rather than a sleuth, possessed the cool ferocity of a ferret when that one love--his love of country--was aroused.
