Down the stairs I hastened, my heart going quick with the alarms of my escape, opened the door at the foot of it and came into the little entry. As I entered it I fancied a sound. It was like a step, very soft, so soft as to be hardly audible, not behind me, not on the other side of the door in front of me, but somewhere beyond the entry partition on my right. It was there, I reckoned, that one of those dark anterooms, through which we had approached the sala, must be. The flesh of my back was pricking, but I was almost safe. Once let me reach Mr. Dingley and I knew that somehow he would get us out. With a great effort I pulled open the heavy door into the sala.
"Oh, I—" I began; but then I stopped. The room was so large that it took me some moments to make sure it was empty. Mr. Dingley was not there.
I stood perfectly still in that stupendous place. Everything in me seemed to have stopped moving, too—my blood and my heart. And, in the listening pause, there came again unmistakably, soft, stealthy footsteps, sounding beyond the heavy curtain of the door—sounding as if creatures were gathering in those dark rooms that lay between me and the outer hall.
I didn't scream. I didn't want to. I walked quite quietly across the room to one of the heavily curtained windows at the back, and pulled the hangings aside.
In front of me, not three feet from the window was the blank face of the convent wall rising straight up, higher than I could see. I looked downward. The stone pavement, which I could just make out in the gloom, must have been ten feet below. Nevertheless I had a wild thought that, if the worst came, I could at least fling myself down the narrow cleft; and in that mind I took hold of the window-frame. I had no hope that I could move it, even after I had stirred the heavy locks; but, with the pressure of all my weight against it, slowly the two sides of the casement opened out. As the dusty panes of glass swung away from before me my eye caught a singular irregularity in the surface of the wall. About on a level with the window-sill was a niche in the masonry, perhaps three feet square, and looking to be the depth of the wall itself. The back of it seemed to be made of a dark substance—darker than the bricks—through which shone twinkling glimpses of daylight.
I climbed upon the window-sill, and, taking hold of the upper edge of one of the casements, swung myself by this. I felt myself hovering an instant in mid-air. Then my feet had found the niche. I crouched, and, groping forward with one hand, grasped a stout tangle of vines. Releasing the casement I half-dragged, half-swung myself into the opening in the wall. I clung there a moment trembling, catching my breath, before I realized that the dark mass at the back of the niche was merely ivy, some of which I had grasped, tearing quite a little opening, and through this I could see a blessed glimpse of blue sky.
Putting my eyes close to this peep-hole I looked downward and saw below me the grass plots of the convent garden. A great tangle of bushes was at the foot of the wall, but in spite of that it looked a dreadful drop. I glanced over my shoulder into the room behind me, and thought I saw a shadow moving down the floor. I do not know how I turned myself in the cramped space where I knelt. All I could remember afterward was the feel of the edge of the rough masonry under my fingers; the tearing of the ivy as my body crushed through it; the straining of my arms as I swung downward. I gave one horrified glance into the depths of the garden; then closed my eyes and let go.
