The Detective Tales cover for March

So I am carrying on with the tradition. This time I chose the Detective Tales cover for March 1938. It is another dramatic cover, filled with action. In this one, the hero is dealing with one badguy bare hand, pushing him down the hole with a firm, decisive hand, easily overpowering his enemy. But the center of the stage is occupied by the damsel in distress, resourceful, as she is about to shoot another badguy aiming at the hero from behind, yet vulnerable, as another villain, looking a lot like a slimy vampire, is about to tied her up with a lasso. I wish I know the story linked to the picture, if there is one of course. Anybody can imagine one?
