When the story begins, Betty is in her apartment and she can't help but look across at some other apartment because there is some sort of big broo-ha-ha going on there. Two women are screaming at each other as some guy tries to settle things down.
The next day, Betty notices in the newspaper that one of the women she saw the night before was reported dead from suicide. Now THIS is a coincidence. Soon the guy from the previous night (Scott Marlowe) and he offers to hire her to investigate this suicide. So although this is a huge conflict of interest (considering they are neighbors and this could get REALLY ugly), she takes the case because, well...she's Betty! What follows sure makes it look as if the man's wife killed the other woman, as apparently years ago, the husband and dead woman were having an affair....and the wife is LESS stable that a crackhead going through withdrawal. In fact, soon the wife begins imagining that Betty and her hubby are having an affair and she destroys Betty's apartment with a butcher knife...and also chases after Betty! Well, it sure seems as if the wife is the killer...but being a 70s detective show, you figure it's really someone else.
I was a bit surprised by the way the wife's psychiatrist was written. Although the woman had a LONG history of unstable behavior and was violent, her therapist sure seemed oblivious to how dangerous she was...only hospitalizing her overnight after this rampage against Betty. He insisted the woman really did NOT intend to kill Betty!! I cannot imagine any therapist thinking this way after a knife attack...and I am a trained psychotherapist. His response was just bizarre....though, conversely, the husband's response to therapy at the end of the show was VERY well written, as he finally admitted that he, too, was part of the problem...which makes a lot of sense.
So why did I still give this one a 6 despite my issues I had with the show. First, compared to many of the Betty shows from seasons 6 and 7, it was STILL significantly better than the rest! Secondly, despite some logical issues, the show still was entertaining.
