The word was still on his lips, when like a tiger-cat, like that which in all the world is most swift to move, like, if you will, the wild boar that will charge an army, the mask darted rather than ran upon his opponent. But at the same time with an incredible lightness. Before Ampoule could place himself in the best posture, before he could bring his sword-point to the level, or deal one of those famous "_estramacons_" which he had been wasting on the empty air, the other was within his guard, they were at close quarters, the advantage of the bigger man's length of arm was gone. How it went after that, who struck, who parried, not the most experienced eye could see. So quick on one another, so furious, so passionate were the half-dozen blows the masked man dealt, that the clearest vision failed to follow them. It was as if a wild cat, having itself nine lives, had launched itself at Ampoule's throat, and gripped, and stabbed, and struck, and in ten seconds borne him to the ground, falling itself with him. But whereas in one second the masked man was up again and on his guard, Ampoule rose not. A few twitches of the limbs, a stifled groan, an arm flung wide, a gasp, and as he had seen many another pass, through the gate by which he had sent not a few, Ampoule passed himself. Of so thin a texture is the web of life, and so slight the thing that suffices to tear it. Had the masked stranger ridden another road that night, had he been a little later, had he been a little sooner; had the trooper refrained from his jest or the men from the wine-pot, had Roger kept his distance, or the arrow-slit looked another way--had any one of these chance occasions fallen other than it fell, Ampoule had lived, and others perchance had died by his hand! All passed, it has been said, with incredible swiftness; the attack so furious, the end a lightning-stroke. Roger on the bridge awoke from a doubt of his ally's courage to see a whirl, a blow, a fall; and then on the ground ill-lighted and indistinct--for half the men had dropped their lights in their excitement--he saw a grim picture, a man dying, and another crouching a pace from him, watching with shortened point and bent knees for a possible uprising. But none came; Ampoule had lived. And presently, still watching cautiously, the mask raised himself and dropped his point. A shiver, a groan passed round the square. A single man swore aloud. Finally three or four, shaking off the stupor of amazement, moved forwards, and with their eyes assured themselves that their officer was dead. At that Roger, still looking on as one fascinated, shook himself awake, in fear for his principal. He expected that an attack would be made on the masked man. None was made, however, no one raised hand or voice. But as he moved towards him, to support him were it needful, the unexpected happened. The unknown tottered a pace or two, leant a moment on his sword-point, swayed, and slowly sank down on the ground.
