Ride the river.

In Ride the River, Louis L'Amour spins the tale of a young woman who has to protect her family fortune from a murderous thief and teach him what it means to be a Sackett. Sixteen-year-old Echo Sackett had never been far from her Tennessee home--until she made the long trek to Philadelphia to collect an inheritance. Echo could take care of herself as well as any Sackett man, but James White, a sharp city lawyer, figured that cheating the money from the young girl would be like taking candy from a baby. If he couldn't hoodwink Echo out of the cash, he'd just steal it from her outright. And if she put up a fight? There were plenty of accidents that could happen to a country girl on her first trip to the big city.From the Paperback edition.
