Stocks and Bondage

S1, E9: A female financial analyst with a fetish for sexual bondage is found hanging dead, but while Detectives Benson (Mariska Hargitay) and Stabler (Christopher Meloni) debate if her death was a suicide or homicide, they discover that the victim recently tried to purchase $10 million of diamonds -- all of which leads to a Wall Street financier (guest star Geoffrey Nauffts) with a mean streak. During their hunt, they cross paths with a Tennessee insurance investigator (guest star Craig Heidenreich), a crooked charity organizer (guest star Christopher McCann) and other low-lifes from the sado-bondage scene. Richard Belzer, Dann Florek, Michelle Hurd and Dean Winters also star.
