 On the next Fresh Air, the biggest financial Ponzi scheme in history. We'll talk with investigative journalist Richard Behar. His new book about Bernie Madoff is based on interviews with FBI agents, Wall Street insiders, and over 50 interviews with and hundreds of emails from Madoff while he was in prison. We'll hear excerpts of those interviews. Join us. Fresh Air coming up at noon and again at 10 o'clock this evening here on KUNR 721.
