"You see yon lights, Agnes!" said Wagner, pointing toward the mansion which, as we stated at the commencement of that chapter, was situated at a distance of about two hundred yards from Fernand's dwelling, the backs of the two houses thus looking toward each other. "Those lights," he continued, "are shining in a mansion the gardens of which are separated from my own by a simple hedge of evergreens, that would not bar even the passage of a child. Should any inmate of that mansion possess curiosity sufficient to induce him or her to cross the boundary, traverse my gardens, and approach the casements of my residence, that curiosity may be easily gratified." "And to whom does yon mansion belong?" asked Agnes. "To Dr. Duras, an eminent physician," was the reply. "Dr. Duras, the physician who attended my noble Andrea in his illness!" exclaimed Agnes. "Then the mysterious lady of whom I have spoken so much, and whose countenance ere now appeared at the casement, must be an inmate of the house of Dr. Duras; or at all events, a visitor there! Ah! surely there is some connection between that lady and the family at Riverola?" "Time will solve the mystery, dearest sister, for so I am henceforth to call you," said Fernand. "But beneath this roof, no harm can menace you. And now let me summon good Dame Paula, my housekeeper, to conduct you to the apartments which have been prepared for your reception. The morning is far advanced, and we both stand in need of rest." Dame Paula, an elderly, good-tempered, kind-hearted matron, shortly made her appearance; and to her charge did Wagner consign his newly-found relative, whom he now represented to be his sister. But as Agnes accompanied the worthy woman from the apartment, she shuddered involuntarily as she passed the frame which was covered with the black cloth, and which seemed ominous amidst the blaze of light that filled the room. CHAPTER X. FRANCISCO, WAGNER AND NISIDA. On the ensuing evening, Francisco, Count of Riverola, was seated in one of the splendid saloons of his palace, pondering upon the strange injunction which he had received from his deceased father, relative to the mysterious closet, when Wagner was announced. Francisco rose to receive him, saying in a cordial though melancholy tone, "Signor, I expected you." "And let me hasten to express the regret which I experienced at having addressed your lordship coldly and haughtily last night," exclaimed Wagner. "But, at the moment, I only beheld in you the son of him who had dishonored a being very dear to my heart." "I can well understand your feelings on that occasion, signor," replied Francisco. "Alas! the sins of the fathers are too often visited upon the children in this world. But, in whatever direction our present conversation may turn, I implore you to spare as much as possible the memory of my sire."
