John Spencer once again takes to the high seas. Young John is charmed by the Dragon, the schooner he is planning to sail to London and use for the honest wool trade. But a mysterious gentleman delivers an ominous warning to ‘steer clear of that ship,’ because the ship was ‘christened with blood.’ The ship looks clever and quick, and the crew seems to know how to man it, but with such a warning John is left to wonder how well he really knows what lies ahead. Will he heed the advice given by the mysterious man? Or will he brave the unknown on his own?
