An excellent second-season episode, 'Wolf in the Fold' resembles a good old-fashioned murder mystery more than anything. Written by Robert Bloch (author of 'Psycho'), it has a nice spooky feeling to it and a genuinely creepy ending that makes it unique among Trek installments. Scotty is suspected of murdering an exotic dancer while on shore leave with Kirk and McCoy on the planet of Argellius II. Other murders follow and each time, Scotty is the prime suspect. He seems to black out when each is committed and so cannot honestly deny at least the possibility that he's responsible. Ultimately, with the help of the ship's computer, it is discovered Jack the Ripper no less is the murderer... or rather, an alien force who has masqueraded as that famous killer and others down through the centuries. There are a number of nice touches in 'Wolf in the Fold,' including a scary séance that would be right at home in an old haunted house movie. A well-written change of pace for 'Star Trek,' 'Wolf in the Fold' holds up well on repeated viewings.
