One doubt M. de La Tour d’Azyr had entertained, though only faintly, to mar the perfect serenity of his growing optimism. That doubt concerned this man Moreau and his relations with M. de Kercadiou. He knew what once they had been, and how changed they subsequently were by the ingratitude of Moreau’s own behavior in turning against the class to which his benefactor belonged. What he did not know was that a reconciliation had been effected. For in the past month--ever since circumstances had driven Andre-Louis to depart from his undertaking to steer clear of politics--the young man had not ventured to approach Meudon, and as it happened his name had not been mentioned in La Tour d’Azyr’s hearing on the occasion of either of his own previous visits. He learnt of that reconciliation now; but he learnt at the same time that the breach was now renewed, and rendered wider and more impassable than ever. Therefore he did not hesitate to avow his own position. “There is a law,” he answered. “The law that this rash young man himself evokes. The law of the sword.” He spoke very gravely, almost sadly. For he realized that after all the ground was tender. “You are not to suppose that he is to continue indefinitely his career of evil and of murder. Sooner or later he will meet a sword that will avenge the others. You have observed that my cousin Chabrillane is among the number of this assassin’s victims; that he was killed on Tuesday last.” “If I have not expressed my condolence, Azyr, it is because my indignation stifles at the moment every other feeling. The scoundrel! You say that sooner or later he will meet a sword that will avenge the others. I pray that it may be soon.” The Marquis answered him quietly, without anything but sorrow in his voice. “I think your prayer is likely to be heard. This wretched young man has an engagement for to-morrow, when his account may be definitely settled.” He spoke with such calm conviction that his words had all the sound of a sentence of death. They suddenly stemmed the flow of M. de Kercadiou’s anger. The colour receded from his inflamed face; dread looked out of his pale eyes, to inform M. de La Tour d’Azyr, more clearly than any words, that M. de Kercadiou’s hot speech had been the expression of unreflecting anger, that his prayer that retribution might soon overtake his godson had been unconsciously insincere. Confronted now by the fact that this retribution was about to be visited upon that scoundrel, the fundamental gentleness and kindliness of his nature asserted itself; his anger was suddenly whelmed in apprehension; his affection for the lad beat up to the surface, making Andre-Louis’ sin, however hideous, a thing of no account by comparison with the threatened punishment. M. de Kercadiou moistened his lips. “With whom is this engagement?” he asked in a voice that by an effort he contrived to render steady.
