(A camera flashes in GRISSOM'S face. (He pushes the door open and finds PAUL MILLANDER dead in the bathtub, a tape recorder left behind.) August 17, 1956. Catherine: Always the same judge? Catherine: Hasn't changed his M.O .-- Kills men whose birthdays are on the anniversary of his father's murder. Grissom: Could be Millander's. Grissom: From what I can tell, he was shot once in the chest. Grissom: In descending order -- first victim was August 17, 1959; second victim, August 17, 1958; this guy, 1957. Gunshot, suicide script leaves the body in a bathtub. It's got to be the work of Paul Millander. So that's about a three hour window. The victim's birthday is always on the anniversary of the murder of Millander's father.
Plan: A: Grissom; Q: Who's birthday is August 17, 1956? A: serial killer Paul Millander; Q: Who is Grissom's nemesis? A: Matt O'Toole; Q: Who played Paul Millander? A: his father's murder; Q: What does the latest slaying recreate? A: a boy; Q: What was Millander when he witnessed his father's murder? A: A nearby tape recorder; Q: What contains the person's supposed suicide message? A: 1959; Q: What year was the first victim born? A: Aug. 17, 1956; Q: When was Grissom born? Summary: Grissom's nemesis, serial killer Paul Millander (Matt O'Toole), reappears and claims a third victim in this gripping episode. The latest slaying matches Millander's previous killings in that it recreates his father's murder, which Millander witnessed as a boy. In each case, the victim is shot once through the chest while lying in a bathtub. A nearby tape recorder contains the person's supposed suicide message. All three victims share the same birthday of Aug. 17---the date Millander's father was slain---with the years in descending order from 1959. So presumably, the killer's next target was born Aug. 17, 1956...which just happens to be Grissom's birthday.
