What seems like an open-and-shut suicide for Sgt Joe Friday and partner Bill Gannon (Jack Webb and Harry Morgan) turns out to be anything but. The medical examiner discovers a slug from an automatic (not the gun found in the victim's hand) and presents his findings to Friday and Gannon changing the whole dynamic of their case. Maybe the testimony of the victim's mother-in-law isn't quite as truthful as first thought. This is one of those instances where Friday and Gannon see no evidence of a crime committed, with another member of the police force, forensics, helping them solve a case of murder, made out of a moment of absolute madness due to actions of the victim the night of his death. Nice little close to the first season of the 60s reprisal of Dragnet, with an ironic final frame consisting of a certain book, with a bullet in it, found in a fireplace, the camera pulling back to establish a sign that seems to indicate disruption of "God's happy home"
I found it amusing.
