Hmmm, I had never heard this one before. It's a quirky little episode, that has psychological elements. The "ghost" is most likely his conscience. The youth vernacular is very dated, but it has historical value, because the 70's was a decade In which older people were still trying desperately to hold onto the morals and values and rules of the 1950's, and the characters actually portray this, though it may sound strange to a younger listener. This is the value of OTR, that we can hear our country's lost culture of the period in the dialogue. But getting back to this Episode, I would say a good companion piece to this one is to listen to "the Long Blue Line", a better one, which is also about an older Detective dealing with a younger relative
