An unwary rat, creeping across the flagstones, was too late. The mist flowed over it. There was a squeak, cut off, and when the mist had gone a few small white bones were all that remained. Some equally small bones, but fully assembled and wearing a black hooded robe and carrying a tiny scythe, appeared out of nowhere and walked over to them. Skeletal claws tippy-tapped on the stone. “Squeak?” said the ghost of the rat pathetically. SQUEAK, said the Death of Rats. This was really all it needed to know.
