16. Three-in-One

The body of successful real estate agent Hildy Glazer ( Joanne Baron ) is discovered in the basement of an empty building. The odd assortment of clues such as a painter's truck which was spotted at the scene of the abduction belonging to a man named Andy Quinn ( Tom Lipinski ) point Nichols and Stevens in several different directions. When three people appear to be related to the victim, Tommy Quin, Andy Quinn and Dr. Curtis, Nichols develops a theory that these three seemingly unrelated people are connected. To prove his theory, he's forced to consult with the most unlikely expert, his father Doctor Theodore Nichols ( F. Murray Abraham ). His theory proves correct and under questioning they ascertain that Quinn is suffering from a Split personality disorder and the police manage to save Quinn's potential second victim. Last appearances of Jeff Goldblum, Saffron Burrows, and Mary Elizabeth Mastrantonio.
