A creepy instalment in the Crime Doctor series with some horror overtones.
Dr Ordway (Warner Baxter) is employed by Lois (Nina Foch) for help with her sleep walking nightmares. Ordway comes to her home, a big house by the cliffs, and discovers a dead man who everyone thinks died while sleep walking of natural causes, though Ordway doesn't think so. Something quite odd is happening here, and the chemist Frank Swift (George Zucco) plays a very believable mad scientist, up to something in his lab with various gases.
One of the stranger entries in the Crime Doctor series with it's mysterious and, at times, horror feel. The usual red herrings, slight plot holes and twists, and fast moving / changing plot add to a very satisfying watch.
