FATAL FALL NO ACCIDENT -- When the young second-wife of a wealthy investment banker plunges to her death from the roof of her art studio, Detectives Briscoe (Jerry Orbach) and Green (Jesse L. Martin) suspect that the woman's husband (guest star William Atherton) or former boyfriend (guest star Joseph Murphy) may have committed a crime of passion. But when a highly controlled drug known as "dazzle" is found in the victim's system, the detectives must find the source of the high-tech anti-anxiety drug, leading the investigation to an assortment of colleagues and family members displeased with the May-December union.
