The ledge of rock on which the Baron d’Escorval and Corporal Bavois rested on descending from the tower was not more than a yard and a half across its widest part. It sloped down towards the edge of the precipice, and its surface was so rugged and uneven that it was considered very imprudent to stand there, even in the day-time. Thus it will be understood that the task of lowering a man from this ledge, at dead of night, was perilous in the extreme. Before allowing the baron to descend, Bavois took every possible precaution to save himself from being dragged over the verge of the precipice by his companion’s weight. He fixed his crowbar firmly in a crevice of the rock, seated himself, braced his feet against the bar, threw his shoulders well back, and then feeling that his position was secure he bid the baron let himself down. The sudden parting of the rope hurled the corporal against the tower wall, and then he rebounded forward on his knees. For an instant he hung suspended over the abyss, his hands clutching at the empty air. A hasty movement, and he would have fallen. But he possessed a marvellous power of will, and had faced danger so often in his life that he was able to restrain himself. Prudently, but with determined energy, he screwed his feet and knees into the crevices of the rock, feeling with his hands for some point of support; then gradually sinking on to one side, he at last succeeded in dragging himself from the verge of the precipice. The effort had been a terrible one, his limbs were quite cramped, and he was obliged to sit down and rest himself. He fully believed that the baron had been killed by his fall, but this catastrophe did not produce much effect upon the old soldier, who had seen so many comrades fall by his side on fields of battle. What did amaze him, however, was the breaking of the rope--a rope so thick that one would have supposed it capable of sustaining the weight of ten men like the baron. It was too dark to examine the fragment remaining in his possession, but on feeling it at the lower end with his finger, the corporal was surprised to find it quite smooth and even, not rough and ragged as is usual after a break. “It must have been cut--yes cut nearly through,” exclaimed Bavois with an oath. And at the same time a previous incident recurred to his mind. “This,” thought he, “explains the noise which the poor baron heard in the next room! And I said to him: ‘Nonsense! it is a rat!’”
