PUNQ’s review published on Letterboxd:
You'll not find Secret of the Chateau to be one of the better 'old dark house' murder mysteries, but what you can't take away from it is that it's highly entertaining. Much to do with Alice White as the spunky blond trying to get her money by blackmail stealing the protectors wig and what not. It's the cutest little chase you'll ever see! Little Ferdinand Gottschalk as the investigator helps liven things up. They also have enough suspects and confusion for always something to happen, so it's not dull either. As for who done it.... don't have to be a professor to figure that one out.
