Friday (Jack Webb) again teams up with Sgt. Ed Jacobs (Barney Phillips) to investigate the seemingly unmotivated murder of a pretty young secretary. It takes some doing, but the two cops manage to follow the clues to a religious fanatic who has a morbid obsession with the month of September. This episode is based on the Dragnet radio broadcast of September 27, 1951. ~ Hal Erickson, Rovi
