In The Gibbering Things", The Shadow must solve a mystery involving a demented professor and the small creatures that make those gibbering sounds heard in the woods...
As the episode opens, dapper man-about-town Lamont Cranston, (a.k.a The Shadow), is traveling with his lovely friend and companion, Margot Lane. They are going to spend the weekend with her aunt, who lives in rural New Hamsphire. On the way to Aunt Sue's place, their driver entertains them with the local legends about the "haunted woods" nearby.
The driver assures them that it is all just a big bunch of hoo-ha...but people are said to have gone into the woods and disappeared, and there are creatures that make a funny gibbering sound, and there are screech owls that make unnerving screams. But, none of those things should worry them.
When they arrive at Aunt Sue's house...she isn't there. As the search the grounds for her, they hear a gibbering sound...and The Shadow soon discovers that the "haunted woods" are a very, very weird place indeed.
