Simpson Jr., I would love to have a copy of your best-of-the-best compilation, because I agree that this is one of the most compelling episodes of the CBSRMT.  Part of it is the title: "RETURN TO SHADOW LAKE."  I'm in!  Then there's the enigma of the break-in at the cottage, and the journey in the snowstorm, then the unfolding of supernatural events at the cabin -- what more do you want?  I like all of Fielding Farrington's episodes, in fact.  An imaginative writer who knew how to keep the thread tight.
