By fast driving Andre–Louis had reached the ground some minutes ahead of time, notwithstanding the slight delay in setting out. There he had found M. de La Tour d’Azyr already awaiting him, supported by a M. d’Ormesson, a swarthy young gentleman in the blue uniform of a captain in the Gardes du Corps.

Andre–Louis had been silent and preoccupied throughout that drive. He was perturbed by his last interview with Mademoiselle de Kercadiou and the rash inferences which he had drawn as to her motives.

“Decidedly,” he had said, “this man must be killed.”

Le Chapelier had not answered him. Almost, indeed, had the Breton shuddered at his compatriot’s cold-bloodedness. He had often of late thought that this fellow Moreau was hardly human. Also he had found him incomprehensibly inconsistent. When first this spadassinicide business had been proposed to him, he had been so very lofty and disdainful. Yet, having embraced it, he went about it at times with a ghoulish flippancy that was revolting, at times with a detachment that was more revolting still.

Their preparations were made quickly and in silence, yet without undue haste or other sign of nervousness on either side. In both men the same grim determination prevailed. The opponent must be killed; there could be no half-measures here. Stripped each of coat and waistcoat, shoeless and with shirt-sleeves rolled to the elbow, they faced each other at last, with the common resolve of paying in full the long score that stood between them. I doubt if either of them entertained a misgiving as to what must be the issue.

Beside them, and opposite each other, stood Le Chapelier and the young captain, alert and watchful.

“Allez, messieurs!”

The slender, wickedly delicate blades clashed together, and after a momentary glizade were whirling, swift and bright as lightnings, and almost as impossible to follow with the eye. The Marquis led the attack, impetuously and vigorously, and almost at once Andre–Louis realized that he had to deal with an opponent of a very different mettle from those successive duellists of last week, not excluding La Motte–Royau, of terrible reputation.

Here was a man whom much and constant practice had given extraordinary speed and a technique that was almost perfect. In addition, he enjoyed over Andre–Louis physical advantages of strength and length of reach, which rendered him altogether formidable. And he was cool, too; cool and self-contained; fearless and purposeful. Would anything shake that calm, wondered Andre–Louis?

He desired the punishment to be as full as he could make it. Not content to kill the Marquis as the Marquis had killed Philippe, he desired that he should first know himself as powerless to avert that death as Philippe had been. Nothing less would content Andre–Louis. M. le Marquis must begin by tasting of that cup of despair. It was in the account; part of the quittance due.

As with a breaking sweep Andre–Louis parried the heavy lunge in which that first series of passes culminated, he actually laughed — gleefully, after the fashion of a boy at a sport he loves.

That extraordinary, ill-timed laugh made M. de La Tour d’Azyr’s recovery hastier and less correctly dignified than it would otherwise have been. It startled and discomposed him, who had already been discomposed by the failure to get home with a lunge so beautifully timed and so truly delivered.

He, too, had realized that his opponent’s force was above anything that he could have expected, fencing-master though he might be, and on that account he had put forth his utmost energy to make an end at once.

More than the actual parry, the laugh by which it was accompanied seemed to make of that end no more than a beginning. And yet it was the end of something. It was the end of that absolute confidence that had hitherto inspired M. de La Tour d’Azyr. He no longer looked upon the issue as a thing forgone. He realized that if he was to prevail in this encounter, he must go warily and fence as he had never fenced yet in all his life.

They settled down again; and again — on the principle this time that the soundest defence is in attack — it was the Marquis who made the game. Andre–Louis allowed him to do so, desired him to do so; desired him to spend himself and that magnificent speed of his against the greater speed that whole days of fencing in succession for nearly two years had given the master. With a beautiful, easy pressure of forte on foible Andre–Louis kept himself completely covered in that second bout, which once more culminated in a lunge.

Expecting it now, Andre–Louis parried it by no more than a deflecting touch. At the same moment he stepped suddenly forward, right within the other’s guard, thus placing his man so completely at his mercy that, as if fascinated, the Marquis did not even attempt to recover himself.

This time Andre–Louis did not laugh: He just smiled into the dilating eyes of M. de La Tour d’Azyr, and made no shift to use his advantage.

“Come, come, monsieur!” he bade him sharply. “Am I to run my blade through an uncovered man?” Deliberately he fell back, whilst his shaken opponent recovered himself at last.

M. d’Ormesson released the breath which horror had for a moment caught. Le Chapelier swore softly, muttering:

“Name of a name! It is tempting Providence to play the fool in this fashion!”

Andre–Louis observed the ashen pallor that now over spread the face of his opponent.

“I think you begin to realize, monsieur, what Philippe de Vilmorin must have felt that day at Gavrillac. I desired that you should first do so. Since that is accomplished, why, here’s to make an end.”

He went in with lightning rapidity. For a moment his point seemed to La Tour d’Azyr to be everywhere at once, and then from a low engagement in sixte, Andre–Louis stretched forward with swift and vigorous ease to lunge in tierce. He drove his point to transfix his opponent whom a series of calculated disengages uncovered in that line. But to his amazement and chagrin, La Tour d’Azyr parried the stroke; infinitely more to his chagrin La Tour d’Azyr parried it just too late. Had he completely parried it, all would yet have been well. But striking the blade in the last fraction of a second, the Marquis deflected the point from the line of his body, yet not so completely but that a couple of feet of that hard-driven steel tore through the muscles of his sword-arm.

To the seconds none of these details had been visible. All that they had seen had been a swift whirl of flashing blades, and then Andre–Louis stretched almost to the ground in an upward lunge that had pierced the Marquis’ right arm just below the shoulder.

The sword fell from the suddenly relaxed grip of La Tour d’Azyr’s fingers, which had been rendered powerless, and he stood now disarmed, his lip in his teeth, his face white, his chest heaving, before his opponent, who had at once recovered. With the blood-tinged tip of his sword resting on the ground, Andre–Louis surveyed him grimly, as we survey the prey that through our own clumsiness has escaped us at the last moment.
