The Silent Partner's Liquidation

In her city, nobody knows that the chairwoman of one of its largest groups has spent twenty years married to an engineer of no particular standing. The chairwoman is Sarah Miller, and she has kept her position and her name out of the marriage the whole time. She and her husband agreed early on to have no children, and she went through surgery to make that permanent. Her money and her company's resources went into building his career. On their wedding anniversary, twenty years in, she is putting together a surprise for him, a large contract, when she finds him with another woman and a child of his own. She returns to the group as its chairwoman, in the open this time, intending to make the people who deceived her pay for it.
