Calling Dr. Death on AllMovie

In this first of Universal's "Inner Sanctum" mysteries, Lon Chaney Jr. plays a neurologist plagued by a faithless wife. He suffers a bout of insanity, blacks out, and loses all track of time. Upon returning to his home, he discovers that his wife has been murdered. Investigating detective J. Carroll Naish is certain that Chaney is the murderer, and tries to browbeat the suspect into a confession. Chaney himself is half-convinced that he is guilty, and in conducting his own investigation learns the truth. All we can say without spoiling the film is that the truth hurts.
