I woke up one morning with a pentagram, scraped out of the frost, on the outside of my bedroom window. My bedroom was on the second floor, and while there was a first-floor roof, there were only 3 prints in the snow on the first-floor roof which had probably ten feet between the edge and my window.
Also, no prints in the show at the ground level.
This was 20 years ago, and I still wonder what it was about.
