The two years elapsing since Odo's departure from Pianura had widened if they had not lifted his outlook. If he had lost something of his early enthusiasm he had exchanged it for a larger experience of cities and men, and for the self-command born of varied intercourse. He had reached a point where he was able to survey his past dispassionately and to disentangle the threads of the intrigue in which he had so nearly lost his footing. The actual circumstances of his escape were still wrapped in mystery: he could only conjecture that the Duchess, foreseeing the course events would take, had planned with Cantapresto to save him in spite of himself. His nocturnal flight down the river had carried him to Ponte di Po, the point where the Piana flows into the Po, the latter river forming for a few miles the southern frontier of the duchy. Here his passport had taken him safely past the customs-officer, and following the indications of the boatman, he had found, outside the miserable village clustered about the customs, a travelling-chaise which brought him before the next night-fall to Monte Alloro. Of the real danger from which this timely retreat had removed him, Gamba's subsequent letters had brought ample proof. It was indeed mainly against himself that both parties, perhaps jointly, had directed their attack; designing to take him in the toils ostensibly prepared for the Illuminati. His evasion known, the Holy Office had contented itself with imprisoning Heiligenstern in one of the Papal fortresses near the Adriatic, while his mistress, though bred in the Greek confession, was confined in a convent of the Sepolte Vive and his Oriental servant sent to the Duke's galleys. As to those suspected of affiliations with the forbidden sect, fines and penances were imposed on a few of the least conspicuous, while the chief offenders, either from motives of policy or thanks to their superior adroitness, were suffered to escape without a reprimand. After this, Gamba's letters reported, the duchy had lapsed into its former state of quiescence. Prince Ferrante had been seriously ailing since the night of the electrical treatment, but the Pope having sent his private physician to Pianura, the boy had rallied under the latter's care. The Duke, as was natural, had suffered an acute relapse of piety, spending his time in expiatory pilgrimages to the various votive churches of the duchy, and declining to transact any public business till he should have compiled with his own hand a calendar of the lives of the saints, with the initial letters painted in miniature, which he designed to present to his Holiness at Easter.
