By Chip Hitchcock: Anne Jeffreys (January 26, 1923 – September 27, 2017), age 94; played Marion Kerby in Topper (1953-1955 TV version), and soap opera character Amanda Barrington (General Hospital, Port Charles), who (says the New York Times) came under the spell of a vampire. Count me among the 10,000; I never knew soap operas other than Dark Shadows had vampires….
