Donna Mills plays the new bride of Ian Hendry. It's customary for bridegrooms to keep a few secrets from their wives -- and Hendry's got a pip. It seems that he has a twin brother -- a homicidal maniac. Or is it the brother who's normal, and the husband who's crazy? And why does Donna Mills always seem to get mixed up in dilemmas like this? Videotaped for British television, the 74-minute Killer with Two Faces debuted in the U.S. on December 3, 1974, as part of the ABC Wide World Mystery late-night anthology. ~ Hal Erickson, Rovi
