Wolf in the Fold

This episode is surprisingly well written and executed it begins with Scotty not remembering murdering a woman he left a bar with and kirk and spock basically have to prove his innocence but more women keeping dying around Scotty and he has these blackouts where he remembers nothing eventually its all settled on the ship where the annoying guy with the high pitched voice is intact an evil entity is he jack the ripper its possible considering that more murders throughout history have taken place but the evil entity is vanquished in the end by kirk and crew overall an entertaining premise that works well
