The spy, too cowardly to risk his life in so daring a venture, and beginning to see that he had been imposed upon, begged Casanova on his knees to leave him behind, praying for the fugitives--and this Casanova was thankful to do, for Soradici could only have encumbered him. Father Balbi, though for the last hour he had been heaping reproaches on his friend's rashness, was less of a coward than the spy, and as the time had come to start he followed Casanova. They crept out on the roof, and began cautiously to ascend it. Half-way up the monk begged his companion to stop, saying that he had lost one of the packages tied round his neck. 'Was it the package of cord?' asked Casanova. 'No,' replied the monk, 'but a black coat, and a very precious manuscript.' 'Then,' said Casanova, resisting a sudden temptation to throw Balbi after his packet, 'you must be patient, and come along.' The monk sighed, and followed. Soon they had reached the highest point of the roof, and here Balbi contrived to lose his hat, which rolled down the roof, failed to lodge in the gutter, and fell into the canal below. The poor fellow grew desperate, and said it was a bad omen. Casanova soothed him, and left him seated where he was, while he himself went to investigate, his faithful tool in his hand. Now fresh difficulties began. For a long time Casanova could find no way of re-entering the palace, except into the cell they had quitted. He was growing hopeless, when he saw a skylight, that he was sure was too far away from their starting point to belong to any of the cells. He made his way to it; it was barred with a fine iron grating that needed a file. And Casanova only had one tool! Sitting on the roof of the skylight, he nearly abandoned himself to despair, till the bell striking midnight suddenly roused him. It was the first of November: All Saint's Day--the day on which he had long had a curious foreboding that he should recover his liberty. Fired with hope, he set his tool to work at the grating, and in a quarter of an hour he had wrenched it away entire. He set it down by the skylight, and went back for the monk. They regained the skylight together. Casanova let down his companion through the skylight by the cord, and found that the floor was so far away that he himself dared not risk the leap. And though the cord was still in his hands, he had nowhere to fasten it. The monk, inside, could give him no help--and, not knowing what to do, he set out on another voyage of discovery.
