"Van Vuren is not here," said Roussilac gravely. "He ran when the abbé lowered his sword; and so soon as he had gone—nay, before—yonder figure stepped out of the darkness under the cliff and challenged La Salle. You see he has covered his face. It is the mad Englishman who fights for the love of fighting. And the English cover the earth like flies."

"I shall stiffen his arm, be he heretic or devil," said the stout priest; and he went and stood near the duellists, and, boldly facing the stranger, cursed him prolifically in the name of Holy Church and the King of Rome.

The stranger did not turn, and only acknowledged the anathemas by a perfectly distinct laugh which issued weirdly from the mask.

No man had ever called La Salle's bravery in question. Facing an enemy, who had started as it were from the rocks before him in the rain and the lightning, he met the resolute attack and parried every lunge. In truth, the priest was a fine swordsman; but his resource in skirmish and detail was here taxed to the uttermost. All he could do at his best was to hold out the short sword, which flashed in and out of the rain, controlled by a wrist of steel and an iron arm. The masked man gave forth no sound of hard breathing. He was a master of swordcraft, and La Salle knew that he had met his match. Here was no nervous Dutchman to be trifled with; no hectoring soldier with a hearty oath and bluff swagger. La Salle sweated, and his breath came pricking in hot gasps, and a cold thrill trickled along his back when he allowed himself to wonder who the enemy might be.

The stranger guarded against treachery, hugging the cliff lest anyone with hostile intentions might pass behind and reach his back. Had he moved out, he would assuredly have beaten down the abbé's defence; as it was, the latter was acting upon the defensive, and doing so with much difficulty.

The rain stopped on an instant. As suddenly the clouds fell back to admit the light; and the rugged shadows of the rocks traced fantastic shapes along the Rue des Pêcheurs.

The strained voice of Laroche broke the stillness.

"A touch!"

"Liar!" shouted back the hard-driven but proud priest, although he felt warm blood oozing between his fingers.

The masked man feared the light which followed the sweeping away of the storm clouds. He bestirred himself, feinted with amazing rapidity within and without the pass, then his limber wrist stiffened for the second, and his point darted in like a poisonous snake over the hilt and wounded La Salle upon the muscle of the sword-arm.
