"You had better lower me, anyhow," said Balbi, without hesitation; for no doubt he was very tired of that slippery roof, on which a single false step might have sent him to his account. "Once I am inside you can consider ways of following me."
That cold-blooded expression of the fellow's egoism put Casanova in a rage for the second time since they had left their prison. But, as before, he conquered it, and without uttering a word he proceeded to unfasten the coil of rope. Making one end of it secure under Balbi's arms, he bade the monk lie prone upon the roof, his feet pointing downwards, and then, paying out rope, he lowered him to the dormer. He then bade him get through the window as far as the level of his waist, and wait thus, hanging over and supporting himself upon the sill. When he had obeyed, Casanova followed, sliding carefully down to the roof of the dormer. Planting himself firmly, and taking the rope once more, he bade Balbi to let himself go without fear, and so lowered him to the floor—a height from the window, as it proved, of some fifty feet. This extinguished all Casanova's hopes of being able to follow by allowing himself to drop from the sill. He was dismayed. But the monk, happy to find himself at last off that accursed roof, and out of all danger of breaking his neck, called foolishly to Casanova to throw him the rope so that he might take care of it.
"As may be imagined," says Casanova, "I was careful not to take this idiotic advice."
Not knowing now what was to become of him unless he could discover some other means than those at his command, he climbed back again to the summit of the roof, and started off desperately upon another voyage of discovery. This time he succeeded better than before. He found about a cupola a terrace which he had not earlier noticed, and on this terrace a hod of plaster, a trowel, and a ladder some seventy feet long. He saw his difficulties solved. He passed an end of rope about one of the rungs, laid the ladder flat along the slope of the roof, and then, still astride of the apex, he worked his way back, dragging the ladder with him, until he was once more on a level with the dormer.
But now the difficulty was how to get the ladder through the window, and he had cause to repent having so hastily deprived himself of his companion's assistance. He had got the ladder into position, and lowered it until one of its ends rested upon the dormer, whilst the other projected some twenty feet beyond the edge of the roof. He slid down to the dormer, and placing the ladder beside him, drew it up so that he could reach the eighth rung. To this rung he made fast his rope, then lowered the ladder again until the upper end of it was in line with the window through which he sought to introduce it. But he found it impossible to do so beyond the fifth rung, for at this point the end of the ladder came in contact with the roof inside, and could be pushed no farther until it was inclined downward. Now, the only possible way to accomplish this was by raising the other end.
It occurred to him that he might, by so attaching the rope as to bring the ladder across the window frame, lower himself hand over hand to the floor of the attic. But in so doing he must have left the ladder there to show their pursuers in the morning, not merely the way they had gone, but for all he knew at this stage, the place where they might then be still in hiding. Having come so far, at so much risk and labour, he was determined to leave nothing to chance. To accomplish his object then, he made his way down to the very edge of the roof, sliding carefully on his stomach until his feet found support against the marble gutter, the ladder meanwhile remaining hooked by one of its rungs to the sill of the dormer.
In that perilous position he lifted his end of the ladder a few inches, and so contrived to thrust it another foot or so through the window, whereby its weight was considerably diminished. If he could but get it another couple of feet farther in he was sure that by returning to the dormer he would have been able to complete the job. In his anxiety to do this and to obtain the necessary elevation, he raised himself upon his knees.
But in the very act of making the thrust he slipped, and, clutching wildly as he went, he shot over the edge of the roof. He found himself hanging there, suspended above that terrific abyss by his hands and his elbows, which had convulsively hooked themselves on to the edge of the gutter, so that he had it on a level with his breast.
It was a moment of dread the like of which he was never likely to endure again in a life that was to know many perils and many hairbreadth escapes. He could not write of it nearly half a century later without shuddering and growing sick with horror.
A moment he hung there gasping, then almost mechanically, guided by the sheer instinct of self-preservation, he not merely attempted, but actually succeeded in raising himself so as to bring his side against the gutter. Then continuing gradually to raise himself until his waist was on a level with the edge, he threw the weight of his trunk forward upon the roof, and slowly brought his right leg up until he had obtained with his knee a further grip of the gutter. The rest was easy, and you may conceive him as he lay there on the roof's edge, panting and shuddering for a moment to regain his breath and nerve.
Meanwhile, the ladder, driven forward by the thrust that had so nearly cost him his life, had penetrated another three feet through the window, and hung there immovable. Recovered, he took up his spontoon, which he had placed in the gutter, and, assisted by it, he climbed back to the dormer. Almost without further difficulty, he succeeded now in introducing the ladder until, of its own weight, it swung down into position.
A moment later he had joined Balbi in the attic, and together they groped about in it the dark, until finding presently a door, they passed into another chamber, where they discovered furniture by hurtling against it. Guided by a faint glimmer of light, Casanova made his way to one of the windows and opened it. He looked out upon a black abyss, and, having no knowledge of the locality, and no inclination to adventure himself into unknown regions, he immediately abandoned all idea of attempting to climb down. He closed the window again, and going back to the other room, he lay down on the floor, with the bundle of ropes for a pillow, to wait for dawn.
And so exhausted was he, not only by the efforts of the past hours, and the terrible experience in which they had culminated, but also because in the last two days he had scarcely eaten or slept, that straightway, and greatly to Balbi's indignation and disgust, he fell into a profound sleep.
He was aroused three and a half hours later by the clamours and shakings of the exasperated monk. Protesting that such a sleep at such a time was a thing inconceivable, Balbi informed him that it had just struck five.
It was still dark, but already there was a dim grey glimmer of dawn by which objects could be faintly discerned. Searching, Casanova found another door opposite that of the chamber which they had entered earlier. It was locked, but the lock was a poor one that yielded to half a dozen blows of the spontoon, and they passed into a little room beyond which by an open door they came into a long gallery lined with pigeon-holes stuffed with parchments, which they conceived to be the archives. At the end of this gallery they found a short flight of stairs, and below that yet another, which brought them to a glass door. Opening this, they entered a room which Casanova immediately identified as the ducal chancellery. Descent from one of its windows would have been easy, but they would have found themselves in the labyrinth of courts and alleys behind Saint Mark's, which would not have suited them at all.
On a table Casanova found a stout bodkin with a long wooden handle, the implement used by the secretaries for piercing parchments that were to be joined by a cord bearing the leaden seals of the Republic. He opened a desk, and rummaging in it, found a letter addressed to the Proveditor of Corfu, advising a remittance of three thousand sequins for the repair of the fortress. He rummaged further, seeking the three thousand sequins, which he would have appropriated without the least scruple. Unfortunately they were not there.
