Before I could well fix my thoughts I was asleep.
I was recalled to consciousness by hearing, even through the pall of sleep that bound me, the crowing of a cock in some of the out-offices of the castle.

At the same instant the figure, lying deathly still but for the gentle heaving of her bosom, began to struggle wildly.

The sound had won through the gates of her sleep also.

With a swift, gliding motion she slipped from the bed to the floor, saying in a fierce whisper as she pulled herself up to her full height: "Let me out! I must go! I must go!" By this time I was fully awake, and the whole position of things came to me in an instant which I shall never--can never--forget: the dim light of the candle, now nearly burned down to the socket, all the dimmer from the fact that the first grey gleam of morning was stealing in round the edges of the heavy curtain; the tall, slim figure in the brown dressing-gown whose over-length trailed on the floor, the black hair showing glossy in the light, and increasing by contrast the marble whiteness of the face, in which the black eyes sent through their stars fiery gleams.

She appeared quite in a frenzy of haste; her eagerness was simply irresistible.
I was so stupefied with amazement, as well as with sleep, that I did not attempt to stop her, but began instinctively to help her by furthering her wishes.
