Description[]
The fog shimmered up over the dark grass, over the bent, scraggly trees. Covering the hill, covering the old graveyard.
And then I heard the horrifying moan. Through the windowpane, I heard a long, low moan floating from the hill.
Human and animal at the same time.
So cold. So sad.
So near...
