Here he suddenly broke off, and a curious grey rigidity stole over his features, as if some invisible hand were turning him into stone. His eyes sparkled feverishly, but otherwise his face was the lace of the dead. The horrible fixity of his aspect at that moment, so terrified Varillo that he gave a loud cry, and almost before he knew he had uttered it, another monk entered the cell. Varillo gazed at him affrightedly, and pointed to Ambrosio. The monk said nothing, but merely took the rigid figure by its arm and shook it violently. Then, as suddenly as he had lost speech and motion, Ambrosio recovered both, and went on talking evenly, taking up the sentence he had broken off—"If we did not choose to be as devils, we might be as gods!" Then looking around him with a smile, he added, "Now you are here, Filippo, you will explain!"

The monk addressed as Filippo remained silent, still holding him by the arm, and presently quietly guiding him, led him out of the cell. When the two brethren had disappeared, Varillo fell back on his pillows exhausted.

"What am I to do now?" he thought. "I must have been here many days!—all Rome must know of Angela's death—all Rome must wonder at my absence—all Rome perhaps suspects me of being her murderer! And yet—this illness may be turned to some account. I can say that it was caused by grief at hearing the sudden news of her death—that I was stricken down by my despair—but then—I must not forget—I was to have been in Naples. Yes—the thing looks suspicious—I shall be tracked!—I must leave Italy. But how?"

Bathed in cold perspiration he lay, wondering, scheming, devising all sorts of means of escape from his present surroundings, when he became suddenly aware of a tall dark figure in the cell,—a figure muffled nearly to its eyes, which had entered with such stealthy softness and silence as to give almost the impression of some supernatural visitant. He uttered a faint exclamation—the figure raised one hand menacingly.

"Be silent!" These words were uttered in a harsh whisper. "If you value your life, hold your peace till I have said what I come to say!"

Moving to the door of the cell, the mysterious visitor bolted it across and locked it—then dropped the disguising folds of his heavy mantle and monk's cowl, and disclosed the face and form of Domenico Gherardi. Paralysed with fear Varillo stared at him,—every drop of blood seemed to rush from his heart to his brain, turning him sick and giddy, for in the dark yet fiery eyes of the priest, there was a look that would have made the boldest tremble.

"I knew that you were here," he said, his thin lips widening at the corners in a slight disdainful smile. "I saw you at the inn on the road to Frascati, and watched you shrink and tremble as I spoke of the murder of Angela Sovrani! You screened your face behind a paper you were reading,—that was not necessary, for your hand shook,—and so betrayed itself as the hand of the assassin!"

With a faint moan, Varillo shudderingly turned away and buried his head in his pillow.

"Why do you now wish to hide yourself?" pursued Gherardi. "Now when you are an honest man at last, and have shown yourself in your true colors? You were a liar hitherto, but now you have discovered yourself to be exactly as the devil made you, why you can look at me without fear—we understand each other!"

Still Varillo hid his eyes and moaned, and Gherardi thereupon laid a rough hand on his shoulder.
