CATHY MORIARTY GUEST-STARS -- After a hit man is slain soon after his latest murderous assignment, Detectives Briscoe (Jerry Orbach) and Green (Jesse L. Martin) check out the contract victim's grifter widow (guest star Cathy Moriarty, "Raging Bull") who could have hired the shady assassin to knock off her rich husband as his last kill. But while they investigate her promising motives, the cops discover that her 20-year-old daughter might have had her own deadly reasons as well.
