It is said that in Ulthar, which lies beyond the river Skai, no man may kill a cat; and this I can verily believe as I gaze upon him who sitteth purring before the fire. For the cat is cryptic, and close to strange things which man cannot see.

Once upon a time in Ulthar, before said law was put into action, there lived a sinister old couple who delighting in slaying any unlikely cat that straggled upon their property. This is a tale about two despicable, horrible, awful people who get exactly what is coming to them. I hated them but loved this creepy, atmospheric tale of revenge.

Thank you Irena for bringing this story to my attention.
