"What motive? The most powerful of all the passions that ever drove a woman to become guilty of crime—jealousy; jealousy, Signor Marchese, has been the motive of this murder. Look at the facts as they stand: we know that this Paolina Foscarelli was in the immediate neighbourhood of the spot where the deed was done, and as nearly as possible at the time when it was done; we know—excuse me, Signor Marchese, for speaking very plainly; it is absolutely necessary to be plain—we know that this girl had great reason to feel jealous of La Bianca. Remember that she saw you and the singer driving tete-a-tete together in that solitary place at that unusual hour. I leave it to your own feeling to estimate the degree of jealousy which such a sight, together with other previous circumstances, was calculated to produce in this girl's mind; but, if that be not enough, we know, as a matter of fact, that she had, even previously to seeing what was, so calculated to drive her jealousy to a pitch of fury, expressed jealousy, animosity and hatred against the woman whom she considered as her rival. We have this in evidence—the perfectly unimpeachable evidence of the Signora Orsola Steno. Add to that, again, that the method of the murder was just such as a woman was likely to adopt, and that a man was very little likely to think of, or to have the means of, in his possession. Put all these certain facts together, Signor Marchese; and I think it will be impossible for even your mind to resist the conviction that must force itself upon every one who considers the circumstances."

The Marchese stopped in his agitated walk to and fro across the floor of the chamber, and gazed into the lawyer's face with an expression of bewilderment and pain, which the old man met with a keen and steady glance, and a grave shake of the head. The Marchese, after encountering his eye for a few moments, struck his open hand on his forehead, and threw himself on the chair he had left without uttering a word.

"And to you, Signor Marchese, it assuredly cannot appear strange that the circumstances I have enumerated should carry with them the conviction to other minds that Paolina Foscarelli is guilty of the murder of the singer," continued the lawyer, speaking very slowly and fixing the keen glance of his dark bright eyes on the working face of his companion; "to you, above all others, this cannot appear strange, since—to your own mind this suspicion first occurred."

"What do you mean? I! Signor Fortini. What strange notion is misleading you? I don't know what you mean!" cried the Marchese, while a look of horror gradually crept over his face.

"When the body of the murdered woman was brought into the city,—when we two stood in the gateway, and when your hand raised the sheet that covered the face of the dead, you exclaimed aloud 'Paolina!' What was then the thought that was in your mind? I imagined, at the time, that you recognized her in the dead woman before you. A very few minutes, however, sufficed to show that it was not Paolina, but Bianca who lay there murdered. And then, amid the horror of the first idea of your guilt, which the nature of the circumstances rendered inevitable, I thought no more of the exclamation you had uttered. But I have not forgotten the fact. You did, on seeing Bianca dead before you, exclaim, 'Good God! Paolina!' What was the thought in your mind, Signor Marchese, that prompted that exclamation? What but the sudden spontaneous rush of the conviction that it was she who had done the deed on which you were looking?"

For a few moments the Marchese seemed too much stunned by the inference, and the appeal of the lawyer, and by the vision of the consequences, which he purposed drawing from it, to utter any reply to the demand which had been made on him.

"You mistake, Signor Fortini," he gasped out at last; "you are in error. I cannot have made any such exclamation. I have no consciousness of anything of the kind. In any case no such monstrous idea, as you would infer from it, ever entered into my mind. You know how anxious I was about Paolina's prolonged absence. I was thinking of her; at least, I suppose so, if, indeed, I uttered her name. I have no recollection. I don't know why I should have done so. All I know is that no such horrible and impossible suggestion ever presented itself to my mind for an instant. If it were otherwise," continued the young man, after a few moments of painfully concentrated thought,—"if it were otherwise, why did I not suggest such a solution of the mystery when I found myself accused of the crime?"

"That, Signor Marchese, those who know you best will be least at a loss to understand," replied the lawyer. "The motive that ruled your conduct then, is the same that rules it now. You were then unwilling, as you are now unwilling, to exculpate yourself at the cost of inculpating one who is dear to you. Your objection, I am bound to tell you, carries no weight with it. I cannot abandon that part of my case that rests upon the striking fact that your own first impression was that Paolina was guilty."

"I utterly deny, and will continue to deny, that any such impression was ever present to my mind. I wholly refuse to avail myself of any defence based on any such supposition; on any idea at all, that Paolina Foscarelli is guilty. I know that she is as innocent of this deed as the angels in heaven. I will proclaim her innocence with my last breath. I will not accept any acquittal on the hypothesis of her guilt. I will rather avow that I did the deed myself. In one sense I did so. In one sense I am guilty of her death. For it was I who took her to the place, and into the circumstance that led to her death."

"Signor Marchese, in this matter the truth of the facts is what is wanted. It is that, and that alone that the magistrates will endeavour to discover. A great many facts, as I have pointed out to you, will be before them. Mere statements, one way or the other, will have little avail. Quietly and seriously now, supposing we reject the theory of Paolina's guilt, are you able yourself to conceive any other possible explanations of the facts? Can you yourself suggest any other theory whatsoever?" said the lawyer, throwing his head on one side, and interlacing the fingers of his clasped hands in front of his person, in calm expectation of the Marchese's answer.
