The prime suspect in the murder of a college professor is a domineering father who kidnapped his children and disappeared 15 years earlier.

Detectives Lennie Briscoe and Rey Curtis investigate the death of Marian Hollis a philosophy professor at New York university who jumped - or was pushed - in front of a subway train. She was seen accessing the platform with a tall, well-dressed man. They eventually identify the man as Bill Fallon who is in the city from Cincinnati while his eldest daughter settles in at the university. He denies knowing the dead woman but the police find that he has no personal history prior to 1985. It turns out he is actually Nick Taska, married to Eleanor Taska, and ran off with their children in 1984. Eleanor and the dead woman were once good friends and ADA Abbie Carmichael thinks she may have recognized him on the street, leading Taska to kill her. He denies it and the prosecution face a dilemma when the man's youngest daughter claims she did it. McCoy comes up with a creative way of charging the father.—garykmcd
