A "black widow killer" is at the center of this episode. First, detectives Briscoe (Jerry Orbach) and Curtis (Benjamin Bratt). Next, A.D.A.'s McCoy (Sam Waterston) and Carmichael (Angie Harmon) shed the spotlight of suspicion on Dennis Pollock (Matt Keeslar), a young man who is romantically involved with two considerably older women. ~ Hal Erickson, Rovi
