Kolchak: The Night Stalker is een Amerikaanse serie van de zender ABC. De serie ging in première in 1974.
Kolchak was originally two made-for-TV movies that aired in the early 70's, and featured the adventures of Carl Kolchak, a down-on-the heels reporter who ran afoul of a vampire in Las Vegas and an alchemist in Seattle. These movies proved popular enough that they were spun off into a series, which placed Kolchak in Chicago with the Independent News Service. Each week for 20 weeks he investigated various supernatural and supranatural creatures, ranging from aliens to vampires to Aztec sacrificial cults. Although it only lasted one season on ABC, Kolchak has remained a cult favorite and been kept alive through the efforts of creator Jeffrey Grant Rice, Mark Dawidziak, and the folks at Moonstone Comics, who have two Kolchak comics going (see Links). There's an anthology of Kolchak stories coming out this year and discussion of a new Night Stalker (2005) series produced by The X-Files's Frank Spotnitz for ABC.
Young swinging patrons of an exclusive dating service are turning up, dead of old age. The police don't believe they are the same persons, but Kolchak investigates and discovers that the head of the dating service is actually Helen of Troy, who sacrifices perfect young victims to Hecate, her patron goddess, in return for eternal youth and beauty. The fact that Helen is unaware one of the victims had a glass eye and lied about it on their form proves vital to Kolchak when he accidentally dons one of the rings that lets Helen sacrifice her victims in the appropriate manner.
