The police receive a report that an elderly couple, Walter and Kate Apperson, are missing. Detectives Friday (Jack Webb) and Smith (Ben Alexander) find traces of cyanide in the couple's breakfast dishes. Can it be that the Apperson's dissolute nephew has been up to no good? In one scene set in a barbershop, Sgt. Friday gets his hair cut while questioning a witness! This episode was inspired by the Dragnet radio broadcast of September 7, 1950 ~ Hal Erickson, Rovi
