Summary: John Schuyler, happily married Wall Street lawyer, is appointed as special diplomatic representative to England. By an unhappy accident, his wife and child can't come along; but on the ship with him is "The Vampire," a "notorious woman" who lives off a succession of men she has seduced and ruined. Slighted by Mrs. Schuyler, she has set her sights on the husband. Two months later, we find the Fool languishing with the mistress who has him enmeshed in her toils. Will he follow the others to the depths of degradation?
