Ep 16. Trade This

A seemingly random murder-shooting of a stockbroker takes on new dimensions when Detectives Briscoe (Jerry Orbach) and Green (Jesse L. Martin) discover that the suspected killer was in turn executed by a professional hitman. As Assistant District Attorneys McCoy (Sam Waterston) and Carmichael (Angie Harmon) sniff around the victim's respected stockbroking firm -- and its e-mail transactions -- they catch a whiff of organized crime that could complicate or simplify their case. Steven Hill and S. Epatha Merkerson also star.
