Holmes clashes with archenemy Professor Moriarty in this exciting tale, loosely based on the Doyle story "The Adventure of the Dancing Men." A revolutionary bomb-sight that could help England defeat the Axis powers and the secret code that makes it operational are up for grabs, and only Holmes can prevent them from falling into Moriarty's sinister hands. Basil Rathbone, Nigel Bruce, Lionel Atwill star. 68 min. Standard; Soundtrack: English.
