This episode gives the viewer the feeling they are seeing an updated version of "Peter and the Wolf." Whether we have Jack Webb, the writer - Alf Harris -, or someone else to thank for this modern interpretation, we'll have to wait to hear from someone close to this episode.
In any case, they writer provides dry humor through how Friday has to handle the wife of the suspect (11 calls and at least 2 visits in 19 days) and her reaction at the end. It honestly reminds me of how wives react to the police when they fail to show up, do show up, or arrest an husband for a domestic call.
In the end, the wife really does do the husband in and drives him back to prison, maybe for the rest of his life.
This is a really good Dragnet episode and really perfect as a humorous Dragnet episode.
