Did you ever read her book
? I have to imagine that she probably talked about her time immediately after being let go from Star Trek. I've not read it yet, but intend to eventually getting around to it.
I'm in the process of getting a copy. Having cut my teeth on TOS, in a sense, I view the cast as old friends. Add to that some of the revelations that have come out over the years, the Justman/Solow book and whatever one finds floating on the web, Whitney's story has for me taken on a dramatic new shade.
