Not the person you asked but what (s)he described sounds like "One nation under black mail" by Whitney Web. Actually worried whether the author would get Epsteined herself.
Not the previous commenter, but I would recommend Hiding In Plain Sight, by Sarah Kendzior. It centers on Donald Trump, but covers in great detail what is publicly known about the seedy history of the people in his orbit, including Epstein, and it calls into question how the people in power in the political, business, and media worlds have left so many questions go unanswered.
