THE GHOST WALKS (1934) (http://imdb.com/title/tt0025169/) - This is a good one from the 30's about a group of people who try to impress a theater producer during a stormy night in a big mansion. During the night someone escaped from the mental asylum and their act gets more involved. This comedy mystery is fun, but the audio on my copy is a bit muffled and I missed parts of some good comedy lines. This comedy mystery has a good opening, mansion with all the trappings, the psychic, the mental patient, the producer and his assistant were all very good.
