“Monsieur, tell me them.”

“I desire no better, and intend no less. You know the legend of this house and garden?”

“I know it. Yes. They say that hundreds of years ago a nun was buried here alive at the foot of this very tree, beneath the ground which now bears us.”

“And that in former days a nun’s ghost used to come and go here.”

“Monsieur, what if it comes and goes here still?”

“Something comes and goes here: there is a shape frequenting this house by night, different to any forms that show themselves by day. I have indisputably seen a something, more than once; and to me its conventual weeds were a strange sight, saying more than they can do to any other living being. A nun!”

“Monsieur, I, too, have seen it.”

“I anticipated that. Whether this nun be flesh and blood, or something that remains when blood is dried, and flesh is wasted, her business is as much with you as with me, probably. Well, I mean to make it out; it has baffled me so far, but I mean to follow up the mystery. I mean—”

Instead of telling what he meant, he raised his head suddenly; I made the same movement in the same instant; we both looked to one point—the high tree shadowing the great berceau, and resting some of its boughs on the roof of the first classe. There had been a strange and inexplicable sound from that quarter, as if the arms of that tree had swayed of their own motion, and its weight of foliage had rushed and crushed against the massive trunk. Yes; there scarce stirred a breeze, and that heavy tree was convulsed, whilst the feathery shrubs stood still. For some minutes amongst the wood and leafage a rending and heaving went on. Dark as it was, it seemed to me that something more solid than either night-shadow, or branch-shadow, blackened out of the boles. At last the struggle ceased. What birth succeeded this travail? What Dryad was born of these throes? We watched fixedly. A sudden bell rang in the house—the prayer-bell. Instantly into our alley there came, out of the berceau, an apparition, all black and white. With a sort of angry rush-close, close past our faces—swept swiftly the very NUN herself! Never had I seen her so clearly. She looked tall of stature, and fierce of gesture. As she went, the wind rose sobbing; the rain poured wild and cold; the whole night seemed to feel her.
