This isn't as bad as Leonard Maltin's review would indicate. I liked this far better than the Black Room in which Karloff had the lead role. Here, Karloff has a supporting, not a staring role, but the movie is worth a look. Sets are done nicely, music reminds you of Frankenstein, and acting is good. Basic plot is about an evil Count who lives in a gothic castle, and has killed two Englishmen, whom he sought revenge on. Enter Richard Greene who is out to find what happened to them. In the process, his own life is in 'grave' danger. I won't ruin the ending, which is as good and suspenseful as any. Lon Chaney Jr plays a loyal brute butler, Karloff a doctor of the Count who's not so loyal.
