Muriel Yorke has a fond husband, but he is so absorbed in his duties as head of the detective bureau that he has little time to devote to his wife. He is inattentive, not intentionally, but the fact remains that all of Muriel's pretty arts designed to distract him from his work are in vain. Time hangs heavily on her hands; she takes her meals alone, and gradually sinks into a state of melancholy. One evening while in search of recreation, Muriel visits a fashionable café unattended, and there meets Eric Le Blanc, a gentleman in manners, but in reality the chief of a band of international conspirators. He introduces himself as the Baron de Corril and Muriel keeps her identity a secret. Their friendship soon ripens into love, but Yorke is so deeply absorbed in his duties that he fails to notice the change that has come over his wife.
