Book excerpt: After the news broke of Bernie Madoff's arrest on December 11, 2008, the facts were hard to grasp. Madoff claimed to have stolen fifty billion dollars; the sum seemed impossibly large. But of course it wasn't impossible. And that was only the beginning of the story. As chief investigative correspondent for ABC News, Brian Ross has been on the front lines of the Madoff scandal since the beginning. Throughout the course of his investigation, he and his team have achieved unequaled access to the investigators working to unravel Madoff's fraud, and have succeeded in cultivating sources deep within the walls of Bernard L. Madoff Investment Securities that no other journalist has reached.The result is an unparalleled, fly-on-the-wall view of a life of corrupted luxury and outrageous lies.
