I was just watching "Mind Over Mayhem" last night.
Sad news, R.I.P.
I've always liked her in the really strange film THE GROUP, which was an early thing for her and a lot of other actresses and actors.
Jessica had the gravitas that would have made her appropriate as a guest villainess than the small part she got in her one "Columbo" episode.
She won an Emmy for starring in "Amy Prentiss" a short-lived fourth wheel in the Mystery Movie in 1974-75.
