The Constant Nymph (movie, 1928)

Sanger, an eccentric expatriate composer, dies in his house in the Austrian Alps, leaving his daughters penniless. The young composer Lewis Dodd, a longstanding friend of the family, falls in love with their cousin Florence when she comes to take the girls back to England. But little Tessa Sanger is in love with Lewis herself, and when she runs away from school and comes to live with Florence and her husband, their already-shaky marriage is further undermined
