Ever since [Bill Clinton's] late-September visit to Africa with Kevin Spacey and Chris Tucker - on his new benefactor's customized Boeing 727 - the question of the day has been: Who in the world is Jeffrey Epstein? It's a life full of question marks. He comes with cash to burn, a fleet of airplanes, and a keen eye for the ladies. Epstein is said to run $15 billion for wealthy clients, yet aside from Limited founder Leslie Wexner, his client list is a closely held secret. He's been linked to ... Ghislaine Maxwell, daughter of the mysteriously deceased media titan Robert Maxwell, yet he lives the life of a bachelor, logging 600 hours a year in his various planes. He owns what is said to be Manhattan's largest private house yet runs his business from a 100-acre private island in St. Thomas. Most everyone on the Street has heard of him, but nobody seems to know what the hell he is up to. Which is just the way he likes it. He is an enthusiastic member of the Trilateral Commission and the Council on Foreign Relations. In 1982 ... he set up his own shop, J. Epstein and Co., ...which is where the mystery deepens. [He] immediately began collecting clients, [but only] those with $1 billion-plus. From the get-go, his business was successful. But the conditions for investing with Epstein were steep: He would take total control of the billion dollars, charge a flat fee, and assume power of attorney to do whatever he thought was necessary to advance his client's financial cause. There are no analysts or portfolio managers, just twenty accountants to keep the wheels greased and a bevy of assistants - many of them conspicuously attractive young women - to organize his hectic life.
