"Ike, it's Bernie."

The voice on the phone betrayed Bernard Madoff's Queens upbringing but sounded surprisingly young for a seventy-year-old man. And surprisingly calm, given the circumstances.

"I'm in the FBI office and I'm handcuffed to a chair," Madoff told his lawyer as he broke the news of his arrest for what would soon emerge as the biggest fraud scheme in Wall Street history.

Ira Lee Sorkin, a white-haired, veteran New York trial lawyer known as Ike, was visiting his grand-daughter's nursery school in suburban Washington, D.C., when his cell phone rang. It was the afternoon of December 11.

A former prosecutor in the United States Attorney's office in Manhattan and onetime head of the New York office of the Securities and Exchange Commission (SEC), Sorkin is one of the city's premier criminal defense lawyers. He is as aggressive as they come and not easily caught off guard, but Madoff's call stunned him.

Madoff had called Sorkin ten days earlier and asked to meet with him about a "problem." According to Sorkin, they had been scheduled to meet on Wednesday, December 10, but Madoff canceled the meeting, pushing it back to December 15.

Instead of a day of legal strategy with his defense lawyer, Madoff had decided to set in motion a plan that would involve him confessing to his two sons, Mark and Andrew, and then letting them "do the right thing" and turn him in to the FBI.

He had asked his sons to give him a week to prepare, but events had moved much more quickly than he had planned. Two agents arrived at his Manhattan penthouse apartment at 133 E. 64th Street just before 8:30 a.m.—only twelve hours or so after his sons gave statements to federal prosecutors. Madoff, a meticulous, elegant dresser, was still in his pajamas, bathrobe, and slippers when special agents Ted Cacioppi and B. J. Kang of the FBI stepped off the elevator into apartment 12-A. They sat in his decorator-designed living room, and Cacioppi asked him if there was "an innocent explanation" for what his sons had described.

"No," said Madoff, who then calmly described what he called a "fifty-billion-dollar fraud" that he said he had carried out by himself, with no help from anyone else. The agents told Madoff to get dressed, put him in handcuffs, and took him downtown to FBI headquarters at 26 Federal Plaza, where he was allowed to call his lawyer.

"Bernie, don't say another thing," Sorkin whispered to Madoff on the cell phone, trying not to disrupt the three-year-olds in the nursery school class, and unaware that his client, with no lawyer present, had already made a lengthy—if only partially truthful—confession to the FBI.

From Sorkin's point of view, this was a legal disaster. He would never have advised Madoff to turn himself in and offer up a confession.

"If you have a client who robbed a bank, and there are video surveillance cameras and nine eyewit-nesses, it might be a good idea to have your client turn himself in," Sorkin said. That was not the case with Madoff.
