Twenty years after the death of Cyrus West, his remaining relatives come to his foreboding manor to hear the reading of the will. Cyrus leaves his estate (including the prized West Pearls) to his most distant relative, Annabelle West. The will also stipulates that Annabelle must be deemed sane by a doctor the following morning or she will forfeit the estate and it would be left to another of West's heirs whose named is sealed in an envelope. The person mentioned in the envelope starts a campaign to terrorize Annabelle and convince everyone else in the house that she is insane, including kidnapping the lawyer Crosby. Its up to Annabelle and her distant relative (and romantic interest) Paul uncover the guilty party. This film is a real treat for Old Dark House fans with plenty of suspense, thrills, and mystery to keep the audience in attention from beginning to end. The cast is non-descript with no one really stands out, but Leni's direction and Warrenton's cinematography create the exact mood the film needs. The film's drawbacks are Hale's characterization of Paul and the characters of Cecily and Aunt Susan, who become annoying to watch. Rating, 8.
