Queen's Gambit

She left her post at the head of the group and handed control of the company to her husband. During that period he began a relationship with another woman. The woman came to her in person and provoked her. Her daughter's life was put at risk in the course of it. She then froze her husband's authority at the company and returned to the business herself. In board meetings and at company functions she set up a sequence of moves against the three of them. What came out of it was her husband's conduct behind the marriage, fraud committed by the other woman, and a death her mother-in-law had staged.
