"I have provided for that." And opening a box that lay near her she pulled out a short coil of stout rope with an iron hook fixed at each end. "Fasten one hook to the window there, and throw me the rope. I will fasten the other here, and you will have a passage back. I will wait here for you." I glanced out of the window again. On the left was the Passage of Pity with its dreary, deserted houses, on the right, above me, was a glimpse of sky. Now and again we heard the cooing of pigeons and the flutter of their wings amongst the eaves, but except for this there was no sound, and we were perfectly unobserved. Removing my boots and discarding my sword I climbed out of the window, resting my feet on the ledge beneath it. Cautiously rising to a standing position I found I could see clearly into the room opposite. It was unoccupied, but, so far from being empty, was filled with books and piles of documents. It looked, indeed, as if M. de Mouchy's study had overrun itself into this room. I had, however, made up my mind to take the risk of being present at this meeting whatever the cost might be, and so after another and careful look began the attempt. Between the opposite window and myself was a gap of a little over three feet, so that it was impossible to reach there. Thanks, however, to the forethought of La Marmotte I was enabled to overcome this difficulty, and after a couple of tries, during which the noise made was such as would have certainly aroused attention had anyone been at hand, I succeeded in fixing one of the iron hooks attached to the rope to the ledge of the window. Then, after a strain to test the rope, I let myself swing across the chasm, and found foothold on the opposite ledge. Once there matters were easy, and in a trice I had passed through the window. CHAPTER XXII THE TABLETS OF DOM ANTOINE DE MOUCHY A quick glance around showed me I was alone. Turning back to the window I swung the free end of the rope to La Marmotte. She caught it, drew it in, and closed the window over it as far as it would go. Through the slight opening I saw for an instant the glow of the candle. Then the rope tightened, and the light went out. I crept softly to a door on my right, and standing there listened intently. All was silence. I tried the door; it opened, and I saw before me De Mouchy's study. His table, littered with papers, was almost in the centre of the room. Near the window was a large carved chest. The walls were lined with books, and three or four bookcases, filled with dust-laden volumes, projected at right angles from them. In truth, it seemed as if Dom Antoine owned a library that might rival that of the Abbey of St. Victor.
