Thelma Todd was a nice-looking, funny actress who worked with the likes of Laurel and Hardy and the Marx Brothers. She mysteriously died in 1935.
What is interesting to the fans of "Vic and Sade" is that the cast of the show received a letter from her, shortly after they were informed of her death. It may have been that the postal card was the last thing she had written, or certainly, one of the very last things she wrote.
There's a new book about her and her death and the mystery behind it all. Whether or not the book addresses the "Vic and Sade" postal card or not is not known by me.
