Henry Kuttner, The Salem Horror (1937)
“ You've become a tool in the hands of tremendous terrible forces, Carson. For three centuries Abbie Prinn has lain in her grave—undead—waiting for someone to fall into her trap—the Witch Room. Perhaps she foresaw the future when she built it, foresaw that someday someone would blunder into that hellish chamber and be caught by the trap of the mosaic pattern. It caught you, Carson—and enabled that undead horror to bridge the gulf between consciousness and matter, to get en rapport with you. Hypnotism is child's play to a being with Abigail Prinn's frightful powers. ”
