The Duchess of Doubt (1917)

Clover Ames's life consists only of the drudge work that she performs at her Aunt Sarah's boardinghouse. No longer able to withstand her aunt's abuse, Clover runs away and obtains a job as a maid to a wealthy woman. Willed $7,000 by Pierre Dubois, a boarder at her aunt's house, Clover, inspired by a novel that she has read, poses as a duchess at a fashionable winter resort. There she meets and falls in love with Walter Gray, who is also traveling incognito as a ribbon clerk. When Clover's money runs out, her trick is discovered and she vanishes. Obtaining employment in Gray's department store, Clover learns that her ribbon clerk is actually the owner's son, who rushes her to the wedding bureau.
