Law & Order S1E10: Prisoner of Love

Overview

The apparent suicide of a controversial bisexual artist, who died while engaging in an apparent act of auto-erotic strangulation, leads Detectives Greevey and Logan into the city's bondage/S&M subculture. The initial explanation for the artist/victim's position is that he was involved in a "performance art work." Further investigation reveals that, in fact, he was one of a sadomasochistic trio that included the head of the New York Department of Cultural Affairs and his "mistress," a wealthy socialite dominatrix who instigated and monitored the S&M scene that led to the artist's death.
