We thought we knew the story of Bernie Madoff. How he masterminded the biggest Ponzi scheme in history, leaving behind scores of distraught investors and a $65 billion black hole. But we had never heard the story from Madoff himself. This week, reporter Steve Fishman and former Radiolabber Ellen Horne visit our studio to play us snippets from their extraordinary Audible series Ponzi Supernova, which features exclusive footage of the man who bamboozled the world. After years of investigative reporting – including interviews with dozens of FBI and SEC agents, investors, traders, and attorneys – the pair scrutinize Madoff’s account to understand exactly why he did it, how he managed to pull it off, and how culpable he actually was. Was he a puppetmaster or a puppet? And if the latter, who else is to blame for the biggest financial fraud in history?
