Cast & Crew
Diane, a child of four, interrupts the frightening party noises in an adjoining room. Because a guest remarks to her mother Cora May, a reigning Parisian demimonde, that the child "has the devil in her eyes, Cora, just like you," Cora puts Diane in a convent. At nineteen, Diane visits a friend by the seashore and meets the Duke of Cluny, who, confused by Diane's innocence and devilish eyes, courts her. Diane, ignorant of her inherited "hidden weakness," succumbs when he deceitfully promises marriage. Meanwhile, the Duchess of Cluny, in her charity work, meets Cora, dying in a hospital, and promises to care for Diane. When Diane recognizes the duke, both keep quiet to protect the duchess. Later, Diane falls in love with the duchess' brother Lieutenant Dodd, an American navy officer. When Diane overhears the duke tell Dodd, whose proposal she refused, to marry her, she reveals her secret. Dodd mortally wounds the duke in a duel, the duchess forgives the duke and Diane tells Dodd that perhaps some day they will marry.
The play was founded on the novel of the same name by Agnes and Egerton Castle, published in London in 1901.
