"His Excellency—Heaven give him glory!—he was a learned man. Yes, he came now and then." Meschini took possession of the manuscript and carried it off rather suddenly to its place in the drawer. He was a long time in locking it up. Faustina watched him with some curiosity.

"You were here that day, were you not?" she asked, as he turned towards her once more. The question was a natural one, considering the circumstances.

"I think your Excellency was present when I was examined by the prefect," answered Meschini in a curiously disagreeable tone.

"True," said Faustina. "You said you had been here all day as usual. I had forgotten. How horrible it was. And you saw nobody, you heard nothing? But I suppose it is too far from the study."

The librarian did not answer, but it was evident from his manner that he was very much disturbed. Indeed, he fancied that his worst fears were realised, and that Faustina was really trying to extract information from him for his own conviction. Her thoughts were actually very far from any such idea. She would have considered it quite as absurd to accuse the poor wretch before her as she had thought it outrageous that she herself should be suspected. Her father had always seemed to her a very imposing personage, and she could not conceive that he should have met his death at the hands of such a miserable creature as Arnoldo Meschini, who certainly had not the outward signs of physical strength or boldness. He, however, understood her words very differently and stood still, half way between her and the bookcases, asking himself whether it would not be better to take immediate steps for his safety. His hand was behind him, feeling for the revolver in the pocket of his long coat. Faustina was singularly fearless, by nature, but if she had guessed the danger of her position she would probably have effected her escape very quickly, instead of continuing the conversation.

"It is a very dreadful mystery," she said, rising from her chair and walking slowly across the polished marble floor until she stood before a row of great volumes of which the colour had attracted her eye. "It is the duty of us all to try and explain it. Of course we shall know all about it some day, but it is very hard to be patient. Do you know?" she turned suddenly and faced Meschini, speaking with a vehemence not usual for her. "They suspected me, as if I could have done it, I, a weak girl! And yet—if I had the man before me—the man who murdered him—I believe I would kill him with my hands!"

She moved forward a little, as she spoke, and tapped her small foot upon the pavement, as though to emphasise her words. Her soft brown eyes flashed with righteous anger, and her cheek grew pale at the thought of avenging her father. There must have been something very fierce in her young face, for Meschini's heart failed him, and his nerves seemed to collapse all at once. He tried to draw back from her, slipped and fell upon his knees with a sharp cry of fear. Even then, Faustina did not suspect the cause of his weakness, but attributed it to the illness of which he had spoken. She sprang forward and attempted to help the poor creature to his feet, but instead of making an effort to rise, he seemed to be grovelling before her, uttering incoherent exclamations of terror.

"Lean on me!" said Faustina, putting out her hand. "What is the matter?
Oh! Are you going to die!"

"Oh! oh! Do not hurt me—pray—in God's name!" cried Meschini, raising his eyes timidly.

"Hurt you? No! Why should I hurt you? You are ill—we will have the doctor. Try and get up—try and get to a chair."
