Bust as Manners entered the cabin he saw, looking at him from the case of a still-ticking watch on the dresser, the face of the woman he loved- and who had disappeared on the eve of their marriage. On his own ship there was his daughter and Knight, his secretary, getting deeper into their impossible love-affiar. Here was Knight's opportunity. How he solves the double mystery, winning Manners' respect and consent makes a really absorbing story".
