“Your highness asks me what and who has made me a spy upon your actions,” said the negro in a low, monotonous voice, and speaking with mingled firmness and respect. “Those questions are easily answered. The same authority which ordered me to wrest from thine arms some months past the lady who might be unfortunate enough to please your highness’ fancy, exercises an unceasing supervision over you, even on this ship, and in the middle of the mighty sea. To that authority all your deeds and acts are matters of indifference save those which would render your highness faithless to an adoring wife. Remember, my lord, the fate of Calanthe, the sister of your dependent Demetrius, she who was torn from your arms, and whose beauteous form became food for the fishes of the Bosporus.”
“How knew you who she was?” demanded the grand vizier, in a low, hoarse voice, the power of his utterance having been temporarily suspended by the rage that filled his soul at finding his iniquitous design in respect to Nisida thus suddenly baffled by the chief of the three black slaves, whose attendance in this expedition had been forced upon him by the Sultana Valida; “how knew you who she was?” he again asked.
“Rather demand, my lord, what can escape the prying eyes of those by whom your highness has been surrounded ever since the seals of office were in your grasp,” returned the slave.
“But you would not betray that secret to Demetrius, who is now devoted to me, who is necessary to me, and who would loathe me were he to learn the dreadful fate of his sister!” said the grand vizier, with rapid and excited utterance.
“I have no eyes and no ears, great pasha,” said the negro, “save in respect to those matters which would render you faithless to the sister of the sultan.”
“Would to Heaven that you had neither eyes nor ears at all—that you did not exist, indeed!” exclaimed Ibrahim, unable to repress his wrath; then, in a different and milder tone, he immediately added, “Slave, I can make thee free—I can give thee wealth—and thou mayest dwell in happy Italy, whither we are going, for the remainder of thy days. Reflect, consider! I love that deaf and dumb Christian woman who sleepeth there—I already love her to distraction! Thwart me not, good slave, and thou mayest command my eternal gratitude.”
“My lord, two other slaves overhear every word that now passes between us,” responded the Ethiopian, his voice remaining calm and monotonous; “and even were we alone in all respects, I would not betray the trust reposed in me. But not on your highness would the effects of your infidelity to the Princess Aischa fall. No, my lord—I have no authority to harm you. Had your highness succeeded in your purpose ere now, the bow-string would have forever stifled the breath in the body of that deaf and dumb Christian lady; and her corpse would have been thrown forth from these windows into the sea. Such are my instructions, my lord; and thus every object of your sated passion must become your victim also.”
“Better—better were it,” exclaimed Ibrahim, in a tone denoting the profoundest mental anguish, “to be the veriest mendicant who implores alms at the gate of the mosque of St. Sophia, than the grand vizier of the Ottoman Empire.”
With these words he rushed into the adjoining saloon, the negro following and fastening the door behind him. Nisida now began to breathe freely once more. From what perils had she escaped! The violation of her couch by the unprincipled Ibrahim would have been followed by her immediate assassination at the hands of the Ethiopian whom the sultana-mother had placed as a spy on the actions of her son-in-law. On the other hand, she felt rejoiced that the incident of this night had occurred; for it had been the means of revealing to her a secret of immense importance in connection with the grand vizier. She remembered the terms of grief and affection in which Demetrius had spoken of the disappearance of Calanthe; and she had heard enough on that occasion to convince her that the Greek would become the implacable enemy of any man who had wronged that much-loved sister. How bitter, then, would be the hatred of Demetrius—how dreadful would be the vengeance which he must crave against him whose lustful passion had led to the murder of Calanthe. Yes, Ibrahim, thy secret is now in possession of Nisida of Riverola; in the possession of that woman of iron mind and potent energy, and whom thou fondly believest to be deaf and dumb!
Nisida slept no more that night, the occurrences of which furnished her with so much food for profound meditation: and with the earliest gleam of dawn that tinged the eastern heaven, she rose from her couch. Entering the saloon, she opened the windows to admit the gentle breeze of morning; and ere she commenced her toilet, she lingered to gaze upon the stately ships that were plowing the blue sea in the wake of the admiral’s vessel wherein she was. Suddenly her eyes fell upon what appeared to be a small speck at a little distance; but as this object was moving rapidly along on the surface of the Mediterranean, it soon approached sufficiently near to enable her to discern that it was a boat impelled by a single sail. Urged by an undefinable and yet a strong sentiment of curiosity, Nisida remained at the saloon window, watching the progress of the little bark, which bounded over the waves with extraordinary speed, bending gracefully to the breeze that thus wafted it onward. Nearer and nearer toward the vessel it came, though not pursuing the same direction; and in five minutes it passed within a few yards of the stern of the kapitan-pasha’s ship.
