I've been trying to discover the name of a play I saw on tv many years ago. I cant even give an approximate year, except it must have been pre 1969 and I would think after 1958. The actors in it were Barbara Murray, Robert Urqhart and possibly John Justin (not sure about that). Most of the characters were in the house, in modern times, but Barbara Murray was in the garden and I don't think she could come into the house for some reason, and I think she might have been an ancient deity or other mythological figure. Any ideas, folks?
