He says people had an incredible vision of Bernard Madoff as a "spectacularly skillful trader."
Andrew Madoff made his comments Monday during an appearance with his mother, Ruth, and his fiancDee, Catherine Hooper, on NBC's "Today" show.
Their appearance coincided with the publication of "Truth and Consequences" by Laurie Sandell. It contains extensive interviews with family members.
Andrew Madoff says the book provided an opportunity to say in their own words what had really happened, and "to speak to the thousands of victims I don't know."
Ruth Madoff says she doesn't miss her husband. She says: "The villain of all this is behind bars."
