Lilith by George MacDonald

At the foot of the stair lay the moonlit street, and I could hear the unwholesome, inhospitable wind blowing about below. But not a breath of it entered my retreat, and I was composing myself to rest, when suddenly my eyes opened, and there was the head of the shining creature I had seen following the Shadow, just rising above the uppermost step! The moment she caught sight of my eyes, she stopped and began to retire, tail foremost. I sprang up; whereupon, having no room to turn, she threw herself backward, head over tail, scrambled to her feet, and in a moment was down the stair and gone. I followed her to the bottom, and looked all up and down the street. Not seeing her, I went back to my hard couch.

There were, then, two evil creatures prowling about the city, one with, and one without spots! I was not inclined to risk much for man or woman in Bulika, but the life of a child might well be worth such a poor one as mine, and I resolved to keep watch at that door the rest of the night.
