An accountant who has publicly blamed imprisoned con man Bernard Madoff for stealing her family's savings has written a book that will disclose a secret she previously withheld -- they once had an extramarital affair.

Sheryl Weinstein's account, "Madoff's Other Secret: Love, Money, Bernie, and Me," will be published Aug. 25 by St. Martin's Press.

Weinstein, 60, has denounced Madoff publicly at least four times this year, including at the June 29 court hearing where he was sentenced to 150 years in federal prison for masterminding the largest Ponzi scheme in Wall Street history. Weinstein told the judge she met Madoff 21 years ago.

"I now view that day as perhaps the unluckiest day of my life because of the many events set into motion that would eventually have the most profound and devastating effect on me, my husband, my child, my parents, my in-laws and all of those who depended on us," Weinstein said at the hearing.

In addition to details of the affair, the book will include photographs and intimate descriptions of Madoff, St. Martin's spokesman John Murphy said.

He declined to provide an advance copy of the book, which he said was "a fast read" and was ghostwritten.

Weinstein didn't return a call or e-mail seeking comment.

"She's entitled to her free speech, I suppose," Ira Sorkin, a lawyer for Bernard Madoff, said Thursday. "Why one would go public with something like that, I don't know."

Peter Chavkin, a lawyer for Madoff's wife, Ruth, declined to comment.
