No one expected Judith Regan to go quietly. After dropping out of sight for much of this year, on Nov. 13 she filed a lawsuit against News Corp, HarperCollins, and Jane Friedman for defamation, breach of contract, and sex discrimination. Most spectacularly, the lawsuit alleges that Ms. Regan was the victim of a vast conspiracy, set in motion by two unnamed News Corp executives, who were worried that she would expose secrets about her now-indicted former lover Bernard Kerik—the former New York City police commissioner—that would imperil his former boss Rudy Giuliani’s presidential bid. News Corp conspired to not only fire her, according to the lawsuit, but also defame her and discredit her so that any allegations she made would be immediately discounted as the ravings of a crazy person.
