That was Deborah Walley. Deborah Raffin is the daughter of 1940s cinema actress Trudy Marshall. A model in her teens, Raffin turned to films in the early '70s, projecting an image of easily outraged innocence. Her largest film assignments included the starring role in Jacqueline Susann's Once Is Not Enough (1977) and as the (literally) bedeviled heroine in The Sentinel (1977).
She also played Goldie Hawn's part in the weekly television version of Foul Play (1981) and was prominently cast in several made-for-TV movies, as well as the 1988 miniseries Noble House.
While her acting career has not been spectacular, Deborah Raffin has managed a successful book-on-tape service called Dove Audio, and was co-producer and co-writer of the 1993 feature film Morning Glory.
