For years one of the most elusive of the “lost horror films,” this British vehicle for Boris Karloff recently emerged, and, according to Everson is “a very pleasant surprise. It was made right after The Old Dark House and The Mummy, and is a rather interesting combination of themes and moods from both films... The sets are handsome, the Gothic mood well sustained by the atmospheric camerawork of Gunther Krampf, and there is even an effective musical score. In terms of plot, the film is admittedly dangerously close to farce at times... Despite all the red herrings and the casual intermingling of the occult, the supernatural and the plain melodramatic, the plot (within the boundaries of its genre) is quite a good one, with satisfying if not entirely convincing explanations made in the last reel. Its cast, of course, is a beauty, with Karloff and Thesiger, fresh from The Old Dark House, stealing all the honors.”
