Underworld U.S.A. trilogy

A novel of the Kennedy era, portraying the president in a far from flattering light. There are three protagonists: a CIA agent who pimps for JFK, another agent who trains anti-Castro rebels, and a lawyer who is a Mafia hunter. Through their eyes are seen the conflicting interests of the Kennedys, the director of the FBI, organized crime, organized labor, Castro and Cuban exiles. By the author of White Jazz.
