Like Grant, I think in "Murder by the book" Marcia Wallace is the red-haired woman in the crowd after Lilly LaSanka's death. Didn't she speak? I think she did (at least, I remember a female voice in that scene). Maybe someone could recognize that voice.
I was like the world's biggest fan of the old Bob Newhart Show, and I really enjoyed Wallace's sarcasm toward her bosses. Another great supporting talent gone, sigh.
