"Suit yourself, Chevalier," said Olivo. "But do not forget that our card party begins in an hour."
In the turret chamber Casanova sank into a chair. A chill sweat broke out over his body; he shivered as if in the cold stage of a fever; he was seized with such nausea that he felt as if he were about to choke. For a time he was unable to think clearly, and he could do no more than devote his energies to the task of self-restraint without quite knowing why he did so. But there was no one in the house upon whom he could vent his fury; and he could not fail to realize the utter absurdity of a half-formed idea that Marcolina must be in some way contributory to the intolerable shame which had been put upon him.
As soon as he was in some degree once more master of himself, his first thought was to take revenge upon the scoundrels who had believed that he could be hired as a police spy. He would return to Venice in disguise, and would exert all his cunning to compass the death of these wretches--or at least of whomever it was that had conceived the despicable design.
Was Bragadino the prime culprit? Why not? An old man so lost to all sense of shame that he had dared to write such a letter to Casanova; a dotard who could actually believe that Casanova, whom he had personally known, would set his hand to this ignominious task. He no longer knew Casanova! Nor did anyone know him, in Venice or elsewhere. But people should learn to know him once more.
It was true that he was no longer young enough or handsome enough to seduce an honest girl. Nor did he now possess the skill and the agility requisite for an escape from prison, or for gymnastic feats upon the roof-tops. But in spite of his age, he was cleverer than anyone else! Once back in Venice, he could do anything he pleased. The first step, the essential step, was to get back. Perhaps it would not be necessary to kill anyone. There were other kinds of revenge, grimmer, more devilish, than a commonplace murder. If he were to feign acceptance of the Council's proposal, it would be the easiest thing in the world to compass the destruction of those whom he wished to destroy, instead of bringing about the ruin of those whom the authorities had in mind, and who were doubtless the finest fellows among all the inhabitants of Venice! Monstrous! Because they were the enemies of this infamous government, because they were reputed heretics, were they to languish in The Leads where he had languished twenty-five years ago, or were they to perish under the executioner's axe? He detested the government a hundred times more than they did, and with better reason. He had been a lifelong heretic; was a heretic to-day, upon sincerer conviction than them all. What a queer comedy he had been playing of late years--simply from tedium and disgust. He to believe in God? What sort of a God was it who was gracious only to the young, and left the old in the lurch? A God who, when the fancy took him, became a devil; who transformed wealth into poverty, fortune into misfortune, happiness into despair. "You play with us--and we are to worship you? To doubt your existence is the only resource left open to us if we are not to blaspheme you! You do not exist; for if you did exist, I should curse you!"
