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.
It was successful, for in a part of the roof which he had not yet visited he found a ladder left by some workmen, and long enough for his purpose. Indeed, it seemed likely to be too long, for when he tried to introduce it into the skylight, it only entered as far as the sixth round, and then was stopped by the roof. However, with a superhuman effort Casanova, hanging to the roof, below the skylight, managed to lift the other end of the ladder, nearly, in the action, flinging himself down into the canal. But he had succeeded in forcing the ladder farther in, and the rest was comparatively easy. He climbed up again to the skylight, lowered the ladder, and in another moment was standing by his companion's side.
They found themselves in a garret opening into another room, well barred and bolted. But just then Casanova was past all exertion. He flung himself on the ground, the packet of cord under his head, and fell into a sleep of utter exhaustion. It was dawn when he was roused at last by the monk's despairing efforts. For two hours the latter had been shaking him, and even shouting in his ears, without the slightest effect!
Casanova rose, saying:
'This place must have a way out. Let us break everything—there is no time to lose!'
They found, at last, a door, of which Casanova's tool forced the lock, and which led them into the room containing the archives or records of the Venetian Republic. From this they descended a staircase, then another, and so made their way into the chancellor's office. Here Casanova found a tool which secretaries used to pierce parchment, and which was some little help to them—for he found it impossible to force the lock of the door through which they had next to part, and the only way was to break a hole in it. Casanova set to work at the part of the door that looked most likely to yield, while his companion did what he could with the secretary's instrument—they pushed, rent, tore the wood; the noise that they made was alarming, but they were compelled to risk it. In half an hour they had made a hole large enough to get through. The monk went first, being the thinner; he pulled Casanova after him—dusty, torn, and bleeding, for he had worked harder than Father Balbi, who still looked respectable.
They were now in a part of the palace guarded by doors against which no possible effort of theirs could have availed. The only way was to wait till they were opened, and then take flight. Casanova tranquilly changed his tattered garments for a suit which he had brought with him, arranged his hair, and made himself look—except for the bandages he had tied round his wounds—much more like a strayed reveller than an escaped prisoner. All this time the monk was upbraiding him bitterly, and at last, tired of listening, Casanova opened a window, and put out his head, adorned with a gay plumed hat. The window looked out upon the palace court, and Casanova was seen at once by people walking there. He drew back his head, thinking that he had brought destruction upon himself; but after all the accident proved fortunate. Those who had seen him went immediately to tell the authority who kept the key of the hall at the top of the grand staircase, at whose window Casanova's head had appeared, that he must unwittingly have shut someone in the night before. Such a thing might easily have happened, and the keeper of the keys came immediately to see if the news were true.
Presently the door opened, and quite at his ease, the keeper appeared, key in hand. He looked startled at Casanova's strange figure, but the latter, without stopping or uttering a word, passed him, and descended the stairs, followed by the frightened monk. They did not run, nor did they loiter; Casanova was already, in spirit, beyond the confines of the Venetian Republic. Still followed by the monk, he reached the water-side, stepped into a gondola, and flinging himself down carelessly, promised the rowers more than their fare if they would reach Fusina quickly. Soon they had left Venice behind them; and a few days after his wonderful escape Casanova was in perfect safety beyond Italy.
