A mine owner in fear for his life sends for great English detective Sexton Blake (David Farrar), and the sleuth soon finds himself investigating murder and more. Hectic and choppy, with far too much going on to follow the story as it jumps around, but interesting withal, though the version I saw was also so muffled in sound that it was even more difficult to know just what was going on.
Mildly recommended. Otto judiciously thinks this movie is OK, but not great.
Movie 28 for 2021.
