Like its companion feature, "Crackle of Death" (copyright 1974), this feature (copyright 1975) is comprised of two episodes of the great teleseries KOLCHAK:THE NIGHT STALKER, which ran for only twenty episodes in the fall 1974-75 season. "COD" was comprised of episodes 6 ("Firefall") and 10 ("The Energy Eater"), while episodes 16 ("Demon in Lace") and 17 ("Legacy of Terror") formed the basis for this one. This was the reason that these four entries were, for many years, unavailable in syndication, whether on the CBS LATE MOVIE or on cable's Sci Fi channel. Both features ventured back and forth between two different plot lines with often dizzying results, new voice-over work from actors Darren McGavin and Simon Oakland helping to bridge the gaps. "Demon in Lace" was about a female succubus who enters the bodies of recently deceased young women to seduce healthy male college students who die from heart attacks, with good roles for Jackie Vernon, Carolyn Jones, and Andrew Prine as an archaeologist who uncovers the secret behind the horror. "Legacy of Terror" had numerous victims being found with their hearts cut out, sacrifices to an Aztec mummy on the verge of being restored to life, with its final, willing, sacrifice being played by a young Erik Estrada. Viewing all four individual episodes is the best way to see them intact, now that the entire series is available on DVD, but these two 'features' still warrant a look for the curious, last broadcast on the Sci Fi channel in 1998.
