Murder At Dawn (1932)

Tucked away deep in the mountains in his secret laboratory, an eccentric scientist is hard at work on a new invention. Using the sun as a power source, Professor Farrington’s "VXO Accumulator" promises to create infinite energy. But before the professor can unveil his scientific masterpiece to the world, he is abducted from his secret laboratory, and his colleague, Judge Folger, is strangled by a mysterious killer. Each room in Farrington’s hideaway contains the ingredients necessary for a brew of science fiction fantasy and horror. Equipped with trap doors, special effects, and the same equipment designed by Kenneth Strickfaden for the films FRANKENSTEIN and BRIDE OF FRANKENSTEIN, the spooky old hideout makes the perfect setting for this offbeat murder mystery.
