This was a bit of a disappointment for me as I usually find Simak novels more engaging. About halfway through, I was almost ready to give up, but decided to continue since it was a short book.
There was a touch of Lovecraft in the sense that the things of madness, the darker side of man's mind might be real. Yet, I don't think that Simak pulled it off as well as Lovecraft does. The ending felt rushed and a bit silly (as did a few other parts of this story).
