[These notes were made in 1993:]. This is a nice little ghost story, with Spock and McCoy taking leading roles on the investigation of a Romulan space station found floating inexplicably abandoned, like the Mary Celeste. Eventually, it proves to be yet another one of those energy-eating creatures, glommed onto the station's power source, and somehow reducing everybody's body temperature at the same time. Of course the Romulans show up and accuse the Federation of sabotage, thus endangering everybody's chances of survival, and Kirk pulls his men (and women) out once again - those who weren't wearing red shirts, that is. Quite atmospheric, especially in the early stages of the exploration of the station.
