The Marquis made the most of an opportunity that might be brief. He quite frankly declared himself, and begged, implored to be taken back into Aline's good graces, to be admitted at least to the hope that one day before very long she would bring herself to consider him in a nearer relationship.

"Mademoiselle," he told her, his voice vibrating with a feeling that admitted of no doubt, "you cannot lack conviction of my utter sincerity. The very constancy of my devotion should afford you this. It is just that I should have been banished from you, since I showed myself so utterly unworthy of the great honour to which I aspired. But this banishment has nowise diminished my devotion. If you could conceive what I have suffered, you would agree that I have fully expiated my abject fault."

She looked at him with a curious, gentle wistfulness on her lovely face.

"Monsieur, it is not you whom I doubt. It is myself."

"You mean your feelings towards me?"

"Yes."

"But that I can understand. After what has happened... "

"It was always so, monsieur," she interrupted quietly. "You speak of me as if lost to you by your own action. That is to say too much. Let me be frank with you. Monsieur, I was never yours to lose. I am conscious of the honour that you do me. I esteem you very deeply... "

"But, then," he cried, on a high note of confidence, "from such a beginning... "

"Who shall assure me that it is a beginning? May it not be the whole? Had I held you in affection, monsieur, I should have sent for you after the affair of which you have spoken. I should at least not have condemned you without hearing your explanation. As it was... " She shrugged, smiling gently, sadly. "You see... "

But his optimism far from being crushed was stimulated. "But it is to give me hope, mademoiselle. If already I possess so much, I may look with confidence to win more. I shall prove myself worthy. I swear to do that. Who that is permitted the privilege of being near you could do other than seek to render himself worthy?"

And then before she could add a word, M. de Kercadiou came blustering through the window, his spectacles on his forehead, his face inflamed, waving in his hand "The Acts of the Apostles," and apparently reduced to speechlessness.

Had the Marquis expressed himself aloud he would have been profane. As it was he bit his lip in vexation at this most inopportune interruption.

Aline sprang up, alarmed by her uncle's agitation.

"What has happened?"

"Happened?" He found speech at last. "The scoundrel! The faithless dog! I consented to overlook the past on the clear condition that he should avoid revolutionary politics in future. That condition he accepted, and now" - he smacked the news-sheet furiously - "he has played me false again. Not only has he gone into politics, once more, but he is actually a member of the Assembly, and what is worse he has been using his assassin's skill as a fencing-master, turning himself into a bully-swordsman. My God Is there any law at all left in France?"

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 pot 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.

M. de La Tour d'Azyr bowed his handsome head, his eyes upon the gleaming parquetry of the floor. "With myself," he answered quietly, conscious already with a tightening of the heart that his answer must sow dismay. He caught the sound of a faint outcry from Aline; he saw the sudden recoil of M. de Kercadiou. And then he plunged headlong into the explanation that he deemed necessary.

"In view of his relations with you, M. de Kercadiou, and because of my deep regard for you, I did my best to avoid this, even though as you will understand the death of my dear friend and cousin Chabrillane seemed to summon me to action, even though I knew that my circumspection was becoming matter for criticism among my friends. But yesterday this unbridled young man made further restraint impossible to me. He provoked me deliberately and publicly. He put upon me the very grossest affront, and... to-morrow morning in the Bois... we meet."

He faltered a little at the end, fully conscious of the hostile atmosphere in which he suddenly found himself. Hostility from M. de Kercadiou, the latter's earlier change of manner had already led him to expect; the hostility of mademoiselle came more in the nature of a surprise.

He began to understand what difficulties the course to which he was committed must raise up for him. A fresh obstacle was to be flung across the path which he had just cleared, as he imagined. Yet his pride and his sense of the justice due to be done admitted of no weakening.

In bitterness he realized now, as he looked from uncle to niece his glance, usually so direct and bold, now oddly furtive - that though to-morrow he might kill Andre-Louis, yet even by his death Andre-Louis would take vengeance upon him. He had exaggerated nothing in reaching the conclusion that this Andre-Louis Moreau was the evil genius of his life. He saw now that do what he would, kill him even though he might, he could never conquer him. The last word would always be with Andre-Louis Moreau. In bitterness, in rage, and in humiliation - a thing almost unknown to him - did he realize it, and the realization steeled his purpose for all that he perceived its futility.

Outwardly he showed himself calm and self-contained, properly suggesting a man regretfully accepting the inevitable. It would have been as impossible to find fault with his bearing as to attempt to turn him from the matter to which he was committed. And so M. de Kercadiou perceived.

"My God!" was all that he said, scarcely above his breath, yet almost in a groan.

M. de La Tour d'Azyr did, as always, the thing that sensibility demanded of him. He took his leave. He understood that to linger where his news had produced such an effect would be impossible, indecent. So he departed, in a bitterness comparable only with his erstwhile optimism, the sweet fruit of hope turned to a thing of gall even as it touched his lips. Oh, yes; the last word, indeed, was with Andre-Louis Moreau - always!

Uncle and niece looked at each other as he passed out, and there was horror in the eyes of both. Aline's pallor was deathly almost, and standing there now she wrung her hands as if in pain.

"Why did you not ask him - beg him... " She broke off.

"To what end? He was in the right, and... and there are things one cannot ask; things it would be a useless humiliation to ask." He sat down, groaning. "Oh, the poor boy - the poor, misguided boy."

In the mind of neither, you see, was there any doubt of what must be the issue. The calm confidence in which La Tour d'Azyr had spoken compelled itself to be shared. He was no vainglorious boaster, and they knew of what a force as a swordsman he was generally accounted.

"What does humiliation matter? A life is at issue - Andre's life."

"I know. My God, don't I know? And I would humiliate myself if by humiliating myself I could hope to prevail. But Azyr is a hard, relentless man, and... "

Abruptly she left him.

She overtook the Marquis as he was in the act of stepping his carriage. He turned as she called, and bowed.

"Mademoiselle?"

At once he guessed her errand, tasted in anticipation the unparalleled bitterness of being compelled to refuse her. Yet at her invitation he stepped back into the cool of the hall.

In the middle of the floor of chequered marbles, black and white, stood a carved table of black oak. By this he halted, leaning lightly against it whilst she sat enthroned in the great crimson chair beside it.
