A brisk historical adventure centers on a roguish English seaman whose daring seamanship and bold tactics lead to fierce naval engagements and hand-to-hand boarding fights with Spanish foes. He rescues and shelters a displaced governor and his daughter, moves through courtly danger and secret plots, and blends swordplay, wit, and gallantry while pursuing romantic aims. The narrative alternates between high-seas action and quieter episodes of intrigue, humor, and chivalrous banter.
