Roulette of Retribution

Rosie Harris is the only daughter of the old gambling king's first wife. As a girl she saw her father cheat on her mother and betray her, and her mother's dying instruction was that she keep her talent for cards and dice out of sight, so she did. She married Mason Innes, who took her side against Thea Harris, the daughter of her father's second wife, and she took that to mean he would be the one to get her out. The two of them were working together against her. Once Rosie understands what Mason is, she stops hiding what she can do at a table and sets about taking back what belongs to her.
