Hedge fund managers are the subject of two recently published books. The latest, by Jill Kargman, is "The Ex-Mrs. Hedgefund," a novel that follows the life of its narrator, socialite Holly Talbott, and her divorce from a hedge fund guy. Though the book is fictitious, it may bear some relation to real life, particularly after the recent publication of "The Manhattan Madam: Sex, Drugs, Scandal and Greed Inside America's Most Successful Prostitution Ring," a tell-all penned by former hedge fund employee Kristin Davis, who went on to launch a Manhattan-based prostitution ring.
