I think writer Dick Nelson "borrowed' a bit from Hitchcock's REAR WINDOW, all about watching a crime in progress. Not a bad idea at all, of course, worked around Betty.
Betty has the terrible fortune of having to live near another building where someone just happens to have their shades open... Accordingly, two women are fighting -- although she does NOT see the murder -- however one of the women turns up dead the next day!
Scott Marlowe plays the husband of the "other" woman (Virginia), well played by Christine Belford, fondly remembered from BANACEK. Belford gives an over the top performance as a deranged person, and perhaps one of the most bizarre of the entire series.
I do agree with the last reviewer, it's amazing her doctor (even in the 70s) did not commit Virginia. In real life, Betty probably would have been Victim No. 2.
But for all us mystery buffs... is this an open and shut case? Definitely, Betty earns her detective stripes in this mystery, albeit violent. Good acting on the part of veteran Scott Marlowe, who later co-starred in the tv soaper VALLEY OF THE DOLLS and DAYS OF OUR LIVES.
An early directing credit for Graeme Clifford. In fact, this was his second tv credit. Clifford was also a well known film editor who worked on THE ROCKY HORROR PICTURE SHOW. Good trivia question.
