On the roof of the Sheridan Apartment House, near Washington Square, New York, is a "small bachelor apartment, penthouse style", and the small bachelor who owns it is amateur artist George Finch, who is rich due to an inheritance. He falls in love with Molly Waddington at first sight, but is too shy to approach her until he retrieves her dog. George's authoritative friend J. Hamilton Beamish, author of self-help books, is helping mild-mannered policeman Garroway become a poet. Garroway recognizes George's valet, Frederick Mullett, an ex-convict who served time for burglary, though Mullett is now reformed. Mullett is engaged to former pickpocket Fanny Welch, who is somewhat less reformed. Wodehouse ties all the disparate plot elements together in a romantic farce worthy of the Jeeves & Wooster tales.
