Cast & Crew
[The following plot summary is based on the English-language version of this film, The Unholy Night : character names refer to that version.] Perceiving a pattern in the mysterious deaths of four members of an English regiment, Sir James Rumsey of Scotland Yard calls together the surviving members of the regiment in the hope of solving the murders. While they are assembled at the Montague mansion, Lady Efra, the daughter of the late Marquis of Cavendar, who was thrown out of the regiment for misconduct, arrives with her father's will. Dividing his vast fortune among Efra and the members of the regiment, and making them guardians of his daughter, Cavendar hoped to harvest his lifelong hatred by causing the regiment to fight over his money and his daughter. Each officer is suspected of being the murderer until Rumsey discovers, through a fake séance, that Efra and Mallory, one of the officers, plan to murder the whole regiment and take possession of the fortune.
