A Lawful Husband

Clarabelle didn't have a choice. She never did. Not when her father passed, and she was forced to sell the family farm to pay off debts, nor when a smooth talking stranger offered to let her travel with him for her own 'safety.' Of course, it didn't matter. Not when she was left to hang for a crime she didn't commit, and certainly not when she was forced into a marriage to save her life.
So why... Why did this strange man save her? Why does he want to take care of her?
