Young woman with friend in tow arrives at a creepy house full of creepy servants to meet her long-estranged father and receive her inheritance. Friend is soon murdered by one of the creepy crowd, and her ghost enlists the help of Cosmo Topper (who has experience with ghosts, of course) to help solve her murder.

Third and last of the Topper series isn't really similar to the first two, but is by far the best. It is either a brilliant parody of the 'old dark house' film, or perhaps the epitome of them. Great cast (especially McBride's doofus cop) and a clever script; one of the few public domain standards that is worth watching everytime it gets shown. Evidentally they rebuilt Tara after the Civil War, because that's where the Toppers are living!
