Great story. I remember hearing this one in 1977 and I enjoyed it. I had no idea Morgan Fairchild was one of the voice actors! Contrary to a comment above, I think the voice actresses did a wonderful job. I remember my grandmother in Virginia sounding very similar, so the impression of a stereotype is unfounded. There is also the fact that the story is set in 1880, so why would the dialogue of the sisters not be characteristic of the Southern belle? As for a brick house burning down, it is conceivable that the red brick appearance was due to a veneer, rather than solid construction. Although solid construction was preferred, cheaper methods of construction have always been used, especially those faced with Gentile poverty. Faux finishes have been used for centuries, but many have not survived. As for a lackluster mystery, many of the Mystery Theater episodes could fall in to that category. Take the adaptations of Shakespeare plays or paranormal themes that involve little or no mystery in themselves. Having listened to most of the shows when they were broadcasted, I received the impression that they were mostly to entertain, rather than serve the mystery enthusiast exclusively.
