"A woman, you tell me? A young woman, I suppose, from what you say?" said the Professor, inquiringly.

"Yes; a young woman, and, as I am told, a very pretty one—a certain young girl—a Venetian artist, of the name of Foscarelli—Paolina Foscarelli, with whom it seems the Marchesino was foolish enough to fall in love. Well, this girl sees the Marchese and Bianca driving out alone together at that time in the morning to the Pineta—that much we know—sees them cheek by jowl together in a little bagarino, doing heaven only knows what—billing and cooing. Now it seems to me that she would, under these circumstances, be likely to feel not altogether kindly towards the lady in possession, eh, Signor Professore? You know the nature of the creatures better than I do; what do you think about it?"

"Similar little accidents have produced as terrible results before now—ay, many a time, there is no denying that. If we can ascertain how the deed was done it will be likely enough to throw some light on the probabilities of the case," returned the Professor, proceeding to scrutinize carefully the body as it lay before in any way disturbing the position or the garments.

"Ha! what have we here?" he cried, as he perceived, and, at the same time, pointed out the existence of a very small red spot upon the white dress just above the waistband. In an instant, as he spoke, he whipped out a powerful magnifying-glass, and carefully examined the tell-tale spot by its aid.

"Yes, that is a spot of blood—blood sure enough! but it is very singular that there should be such a minute spot, and no more; no, I can find no further trace," he added, after a careful and minute examination of every part of the dress.

"Might not any trifling accident—the most insignificant thing in the world—produce such a mere spot as that—a scratched finger—either her own or another person's?" asked the lawyer.

"Well, hardly so; a slight stain might easily be so caused; but hardly a round spot like that. That spot must have been caused by a small drop falling on that place—not by the muslin having been brought into contact with any portion of blood, however small. How could that one little round drop of blood have come there?" said the anatomist, thoughtfully. "It is singular enough."

Then, when the dress had been removed preparatory to the examination of the body, the Professor himself and his assistants minutely searched every part of it—in vain. There was no other, even the smallest, mark of blood to be found.

"Are you sure that that spot is blood?" asked the lawyer.

"Are you sure whether a deed is signed or is not signed when you see it?" retorted the anatomist. "Yes; that spot has been caused by a drop of blood falling there—a very minute drop. Of that there can be no doubt. And now we must proceed to examine the body externally. If there should be nothing to be learned from that, we must see what revelations the knife may bring to light."
