The story
“Lieutenant Monroe, while Uncle Sam’s navy is lying in the harbor of New York, entertains his fiancée, Lillian Rolfe, and Leila, a young woman friend of hers, on board his ship. The Admiral takes note of Lillian’s friend and warns the lieutenant that she is suspected of being the spy of a European government. Later, he tells Monroe that the Navy Department is in possession of certain facts which have made those in authority extremely suspicious. It is recommended that Lieutenant Monroe ostensibly resign and let the fair spy initiate him into her schemes, as she doubtless will do if she imagines that Monroe has left the service under a cloud. The young officer reluctantly consents. He realizes that he cannot confide his plans to Lillian, and that already she half believes that he is in love with Leila. Monroe manages to get involved with the conspirators, who entrust to him the destruction of certain ships of the fleet lying in a New England port.
“He takes command of the yacht, which is to carry the mines to the men of war marked for destruction and then communicates with Admiral Jones by wireless. Meanwhile Lillian is confronted by Jack Homer, the jealous lover of Leila, who he believes has cast him off for the lieutenant. Supposing that the forsaken sweetheart of Monroe will side with him, he tells her of a plot to destroy the yacht, which has been dynamited. Lillian rushes to the wireless station. But it is too late. There is a flash, a roar, and the yacht seems to dissolve before her eyes. Lillian puts to sea in a launch. She rescues her lover. He tells her the whole story of his secret mission. Leila is arrested, the young officer honored by the Department, and he and Lillian are married.”
