Mother suspects foul play when several of his best agents are found dead -- and neatly gift-wrapped. The villain of the piece is named Remak, an acronym for Remote Electro-Matic Agent Killer. With Tara on vacation, Steed must rely upon the assistance of glamorous agent Lady Diana Forbes-Blakeney (Jennifer Croxton) to help him track down the elusive Remak. Written by Tony Williamson, "Killer" first aired in England on January 22, 1969, after its world premiere on American television on December 30, 1968. ~ Hal Erickson, Rovi
