Star Trek episode "Wolf in the Fold"

"Wolf in the Fold"

Season 2, episode 15.

Space belly dancers!

This is the one with Jack the Ripper as the malevolent space entity.

Scotty has "fallen under suspicion" for three murders, even though the direct evidence of him being the only one hovering over the three dead bodies with the knife or blood in his hand.

Direct correlation with the The Next Generation episode from season one called "Justice" where Wesley has to be saved from the planet in direct violation of the Prime Directive. Kirk says, "If they want to arrest him, try to, even convict him, I have to let them."

The only really bad thing about this episode is the Psycho-tricorder that gives a detailed account of everything in a person's conscious or subconscious mind for the last 24 hours. This device, thank goodness, was never used again.

Scotty "kills" Lt. Karen Tracy as one of the three victims, although Kirk couldn't know.
