There were other mysteries, as we shall see. But even after it detonated five months ago in a fireworks display of betrayal and recrimination, Madoff's scheme -- possibly the biggest investment fraud in the nation's history -- has remained among the hardest to penetrate. Most commonly, white-collar cases begin with a quiet, behind-the-scenes investigation, followed by a series of deals with junior employees, who are squeezed by prosecutors to cough up details about their superiors. Step by step, the prosecutors move up. Finally comes the denouement: the ringmaster hauled into court in handcuffs.
But with Madoff every aspect of that traditional narrative has been inverted. The case began with his flabbergasting confession, which set off the investigation. Madoff claimed he committed his crimes all by himself, but because they spanned decades and continents, a fog of suspicion immediately engulfed Madoff family members who worked at the firm, as well as employees and business associates.
Now that fog may be about to lift. Fortune has learned that Frank DiPascali is trying to negotiate a plea deal with federal prosecutors in which, in exchange for a reduced sentence, he would divulge his encyclopedic knowledge of Madoff's scheme. And unlike his boss, DiPascali is willing to name names.
