Leaning against the parapet to support ourselves, our necks stretched toward that window through which there had come to us that sigh of agony, we listened. A quarter of an hour passed thus--it might have been a century! Rouletabille pointed out to me the window of his own room in the New Castle which was still illuminated. I understood: it was necessary to extinguish this light and return. I took a thousand precautions. Five minutes later, I was back again with Rouletabille. There was now no other light in the Court of the Bold than the feeble ray which told of the late vigil of Old Bob in the lower basement of the Round Tower and the light at the gardener’s postern where Mattoni was standing sentinel. In truth, considering the positions which they occupied, one might easily understand how it was that neither Old Bob nor Mattoni had heard anything that had passed in the Square Tower, nor even, in the heart of the storm, could the clamors of Rouletabille have reached their ears. The walls of the postern were heavy and Old Bob was entombed in a veritable subterranean cavern. I had scarcely time to steal back to Rouletabille in the corner of the parapet, the post of observation which he had not quitted, before we distinctly heard the door of the Square Tower moving softly upon its hinges. As I attempted to lean further out of my corner, and see further down into the court, Rouletabille pushed me back and allowed only his own head to look over the wall; but as he was leaning far over, I allowed myself to violate his command and looked over his head; and this is what I saw. First, Pere Bernier, perfectly recognizable, in spite of the darkness, who came out of the tower and directed his steps noiselessly to the gardener’s postern. In the middle of the court, he paused, looked up at the side where our windows were, and then returned to the side of the court and made a signal which we interpreted as a sign that all was well. To whom was this signal addressed? Rouletabille leaned still further over; but he quickly retreated, pushing me back with him.
