But is Hanna a "mature" heroine? All the cast listing says is that she's a wealthy widow. She was a poor farmer's daughter before she married up, and her elderly, wealthy husband obligingly died on their wedding night. So after his death she takes his money with her to live it up in Paris, thereby creating the crisis that starts the plot. But all that indicates only a fairly short period of time has passed. Hanna could even still be in her teens.
