"If it had been any other but Rocca the clown!" he said to himself, his thoughts ever upon the jest; "surely we shall know what to say to him."

He had come almost to the church of San Salvatore by this time. His walk had carried him out to the bank of a narrow, winding canal, at whose quays once-splendid gondolas were rotting in neglect. It seemed to him that here was the place where his tactics might well be changed and the rôle of the hunted put aside for that of the hunter. Quick to act, he stepped suddenly behind one of the great wooden piles driven into the quay for the warping of barges. The bravo, who did not perceive that he had been detected, and who could not account for the sudden disappearance of his prey, came straight on, his cloak wrapped about his face, his naked sword in his hand. The wage would be earned easily that night, he was telling himself. No one would miss a beggarly monk—and he, Rocca, must live. A single blow, struck to the right side of the back, and then—and then—

This pleasant anticipation was cut short abruptly by the total disappearance of the man whose death was a preliminary to the wage he anticipated so greedily. Mystified beyond measure, he let his cloak fall back again, and began to peer into the shadows as though some miracle had been wrought and the priest carried suddenly from earth to that heaven whither he had meant to send him so unceremoniously.

"Blood of Paul!" he exclaimed angrily, turning about and about again, "am I losing my eyes? A plague upon the place and the shadows."

He stamped his foot impotently, and was about to run back by the way he had come when a voice spoke in the shadows; and at the sound of the voice, the sword fell from the man's hand and he reeled back as from a blow.

"Rocca Zicani, the Prince is waiting for you."

The assassin staggered against the door of a house, and stood there as one paralyzed. He had heard those words once before in the dungeons of Naples. They had been spoken by the Inquisitors who came to Italy with one of the Spanish princes. Instantly he recalled the scene where first he had listened to them—the dungeon draped in black—the white-hot irons which had seared his flesh; the rack which had maimed his limbs, the masked men who had tortured him.

"Great God!" he moaned, "not that—not that—"

The priest stepped from the shadows and stood in a place where the feeble light of an oil lamp could fall upon his face. The laugh hovered still about his lips. He regarded the trembling man with a contempt he would not conceal.

"Upon my word, Signer Rocca," he exclaimed, "this is a poor welcome to an old friend."
