Wolf In The Fold has some interesting elements, but it is not a great episode.
It begins with Kirk, McCoy & Scotty enjoying the nightlife on the hedonistic planet Argelius II. Why? Well, Scotty is apparently recovering from a concussion and needs a boost. It seems there was an explosion that threw Scotty against a bulkhead and it was caused by a woman. In McCoy's medical opinion, "considerable psychological damage could have been caused. For example, his total resentment toward women."
One of the reasons I like Star Trek so much (apart from the flying through space part) is that it presents a positive outlook on the future, one where an ugly rock beast can be thought of as being just a mom trying to protect her children. One where no one would categorize who caused an accident by their gender or race. Oh, well. I guess it doesn't always hit the mark, especially in TOS, where things are still a little rough around the edges.
John Fiedler. Some of you may know Fiedler for his job as a voicing the roll of Piglet in Winnie the Pooh. I prefer to think of him as Mr. Peterson in one of my favorite TV series, The Bob Newhart Show. He's one of several actors that were guest actors on both Trek and The Bob Newhart Show.
Hengist is the perfect person to investigate the murder because he is from off-world and the Argelians are gentle, harmless people that apparently aren't very good at this kind of thing. Scotty remembers nothing about what happened and is sticking to that story. While it looks very much like an open and shut case, McCoy doesn't think that Scotty could possibly have committed the crime, even though he thinks that Scotty might have total resentment towards women. Okay, whatever, Doc.
Kirk convinces Hengist to allow him to bring down a member of the Enterprise crew equipped with a psycho-tricorder. Lt. Karen Tracy beams down and heads to back room to check out Scotty's story. What could go wrong?
Return of the Archons), leads the show. Here is her narration of the seance:
Concentrate upon the flame which burns upon the altar of truth. Yes, there is something here. Something terrible. I feel its presence. Fear, anger, hatred. Anger feeds the flame. Oh! Oh! There is evil here. Monstrous, terrible evil. Consuming hunger. Hatred of all that lives. Hatred of women. A hunger that never dies. It is strong, overpowering. An ancient terror. It has a name. Beratis, Kesla, Redjac! Devouring all life, all light. A hunger that will never die! Redjac! Redjac!
At this point, with three murders having committed that all point right at Scotty, the biggest surprise is that he is not immediately hauled off to the electric chair. Instead, Kirk manages to convince Jaris and Hengist that they should all go to the Enterprise to establish Scotty's guilt or innocence.
Eventually, they decide to focus on some of the words that Sybo spoke before she was murdered. They learn that Redjac was a proper name for Jack the Ripper on old Earth and very quickly focus on the hypothesis that they are dealing with an entity that feeds on terror, as Spock says "Deriving sustenance from emotion is not unknown in the galaxy, and fear is among the strongest and most violent of the emotions." And further explaining, "To meet with specified requirements, entity would exist without form in conventional sense. Most probable mass of energy of highly cohesive electromagnetic field.... And I suspect preys on women because women are more easily and more deeply terrified, generating more sheer horror than the male of the species."
This idea of an entity that feeds on emotion will surface again in the Season 3 episode, Day of the Dove, but that's a tale for another day.
Still, the computer threatens the crew, shuts off life support, and creates general mayhem. Thankfully, Spock saves the day with math by having the computer compute Pi to the last digit.
And there you have it. Wolf in the Fold isn't terrible, but for me is very much a middle of the road episode. The idea of the entity and tying it to Jack the Ripper is an interesting plot twist, but they never should have gotten that far as Scotty should have been convicted and locked away long before they figured it all out.
There was one new piece of music composed for this episode (for Kara's belly dance), but it wasn't used. All of the music used in the episode was tracked from other ones.
