Lamont Cranston needs a vacation after his recent exhausting adventures. He picks a resort that is said to be haunted. To combat the aledged supernatural killer ghosts, the Shadow uses his own supernatural ability to put in his own scare. The Shadow soon discovers other strange happenings, blackmail, and murder.
Can the Shadow teach the bad guys a lesson by acting as the voice of their conscience? Will his powers of mind control cause their gang to disintegrate? The Shadow instigates doubt, and double cross between the criminals to the point they start killing each other off. Once there’s enough solid evidence, the cops are called in to sweep up the mess.
PS: I find it amazing in this, and other old radio shows that when the bad guys try to use the supernatural realm as a cover, or basis for their crimes, they are foiled. Their ruse is exposed, and the natural explanation comes out. Yet the good guys use supernatural powers, and are never exposed or found out. Is that fair?
