First of all I must say that nothing, absolutely nothing, can take pleasure in the Three Investigators me. But this episode has me once again demonstrated painfully that the stories are produced on an assembly line. Circa result from 150 it seems to me as if the basic idea of actions super exciting. But then nothing will be out of it yet.
Again ... a creepy monster, a secluded hotel, a helpless lady, an eccentric Butler. All this has the potential for a really good horror novel. And then ... Nothing happened. The action affects gathered and interrupted. Almost as if the editor would have raised the holes in the plot and the author then stuffed hastily.
