Lessons in Love (1921)

Lawyer Hanover Priestley plots with his friend Henry Winkley to marry off young heiress Leila Calthorpe to Winkley's nephew, John Warren. When John refuses, preferring to select his own wife, they lure him east by a false report of Winkley's death. Indignant at his rebuff, Leila disguises herself as Perkins, a maid, and romances him, leading him to believe that Aunt Agatha is the heiress. Complications develop, and after saving her from a fire John discovers her identity and agrees to marry her.
