"Retired FBI Special Agent Mark Sewell was a rookie in 1997 when he was assigned to investigate mafia associate Steve Kaplan and his enormously successful Atlanta strip club; the largest single money maker for the Gambino Crime Family. Accompanied by a small team of investigators, the hand-picked unit followed a money trail, that wound up implicating a Gambino Captain, police officers, strippers, and many of the most recognized professional athletes in America. The subsequent 2001 trial was covered nationally by the leading media outlets, from television newscasts to late night talk shows and nationally published magazines pushing new, sensational headlines daily. Sewell was at the center of the storm that dominated media headlines in the summer of 2001 and provides a never-before seen inside view of the FBI’s most successful financial win against an organized crime family in the agency’s history."
