Henry Kuttner, The Graveyard Rats (1936)
“ And then, too, there was this curious dread of the rats. Masson disliked and respected the ferocious little rodents, for he knew the danger that lurked in their flashing, needle-sharp fangs; but he could not understand the inexplicable horror which the oldsters held for deserted, rat-infested houses. He had heard vague rumours of ghoulish beings that dwelt far underground, and that had the power of commanding the rats, marshalling them like horrible armies. The rats, the old men whispered, were messengers between this world and the grim and ancient caverns far below Salem. ”
