Whimsically, and almost mechanically, he set himself, in his mind, to count the men. There were twenty mercenaries all told, excluding Fortunio and himself. On Arsenio he might rely not to attack him, perhaps even to come to his assistance at the finish. That left nineteen. Four he had already either killed outright or effectively disabled; so that fifteen remained him. The task of dealing with those other fifteen was utterly beyond him. Presently, no doubt, the two now opposing him would be reinforced by others. So that if any possible way out existed, he had best set about finding it at once.

He wondered could he cut down these two, make an end of Fortunio, and, running for it, attempt to escape through the postern before the rest of the garrison had time to come up with him or guess his purpose. But the notion was too wild, its accomplishment too impossible.

He was fighting now with his back to mademoiselle and his face to the tall window, through the leaded panes of which he caught the distorted shape of a crescent moon. Suddenly the idea came to him. Through that window must lie his way. It was a good fifty feet above the moat, he knew, and if he essayed to leap it, it must be an even chance that he would be killed in leaping. But the chance of death was a certain one if he tarried where he was until others came to support his present opponents. And so he briskly determined upon the lesser risk.

He remembered that the window was nailed down, as it had remained since mademoiselle’s pretended attempt at flight. But surely that should prove no formidable obstacle.

And now that his resolve was taken his tactics abruptly changed. Hitherto he had been sparing of his movements, husbanding his strength against the long battle that seemed promised him. Suddenly he assumed the offensive where hitherto he had but acted in self-defence, and a most deadly offensive was it. He plied his cloak, untwisting it from his arm and flinging it over the head and body of one of his assailants, so that he was enmeshed and blinded by it. Leaping to the fellow’s flank, Garnache, with a terrific kick, knocked his legs from under him so that he fell heavily. Then, stooping suddenly, the Parisian ran his blade under the other brave’s guard and through the fellow’s thigh. The man cried out, staggered, and then went down utterly disabled.

One swift downward thrust Garnache made at the mass that wriggled under his cloak. The activity of its wriggles increased in the next few seconds, then ceased altogether.

Tressan felt wet from head to foot with a sweat provoked by horror of what he saw. The Dowager’s lips were pouring forth a horrid litany of guard-room oaths, and meanwhile Garnache had swung round to meet Fortunio, the last of all who had stood with him.

The captain came on boldly, armed with sword and dagger, and in that moment, feeling himself spent, Garnache bitterly repented having relinquished his cloak. Yet he made a stubborn fight, and whilst they fenced and stamped about that room, Marius came to watch them, staggering to his mother’s side and leaning heavily upon Tressan’s shoulder. The Marquise turned to him, her face livid to the lips.

“That man must be the very fiend,” Garnache heard her tell her son. “Run for help, Tressan, or, God knows, he may escape us yet. Go for men, or we shall have Fortunio killed as well. Bid them bring muskets.”

Tressan, moving like one bereft of wits, went her errand, while the two men fought on, stamping and panting, circling and lunging, their breath coming in gasps, their swords grinding and clashing till sparks leapt from them.
