Jill had money, Jill was engaged to be married to Sir Derek Underhill. Suddenly Jill becomes penniless, and she is no longer engaged. With a smile, in which there is just a tinge of recklessness, she refuses to be beaten and turns to face the world. Instead she goes to New York and becomes a member of the chorus of "The Rose of America," and Mr. Wodehouse is enabled to lift the curtain of the musical comedy world.

There is laughter and drama in _Jill the Reckless_, and the action never flags from the moment that Freddie Rooke confesses that he has had a hectic night, down to the point where Wally says briefly "Let 'em," which is page 313. The heroine here, Jill Mariner, is a young woman from the lower end of the upper class. We follow her through financial disaster, a broken engagement, an awkward stay with some grasping relatives, employment as a chorus girl, and of course, the finding of true love. Other characters include wealthy Drone Freddie Rooke and writer Wally Mason, her childhood friends; her financially inept uncle Major Christopher Selby; her fiancée at the beginning of the book, the M.P Derek Underhill, and his domineering mother, Lady Underhill; Jill's unpleasant relatives, Elmer and Julia Mariner; more Drones Club members, various chorus girls, composers and other theatrical types, and, of course, miscellaneous servants.
