When the Duke of Wynningham, a "simple soul" who prefers science to royalty, meets Molly Shine, a London shop girl, he is enthralled by her love of books and begins to send her two pounds weekly so that she can purchase the books that she adores. Molly's mother discovers the money and, assuming that the duke is paying her daughter for immoral reasons, drags the girl to the duke's home, where she charges him with seduction.
