Synopsis by Hal Erickson
A woman is the seemingly random victim of a letter bomb. As the detectives and the D.A.'s office pursue their investigation, it becomes painfully apparent that the killing was no accident of fate. It seems that the dead woman was the estranged wife of scientist Edward Manning (Harris Yulin), and she had driven him to distraction by delaying their divorce proceedings. This episode was directed by former Law & Order regular Dann Florek.
