in the beginning episodes of DS, Josette appears several times-emerging from the portrait and once on the steps of Collinwood to tell David to go help the psychologist in the drawing room.
KLS played Josette emerging from the portrait, and Rosemary McNamara played her ghost in the episode where she sends David to save Dr. Guthrie as well as a couple of other times earlier in the Laura story.
Is there a book or website that cites this information? I'd be interested in knowing which actress played the role in each specific episode. As well as all the other "stand-in" roles on the show.
