“Here, must you be blindfolded,” said the spy.

For a few moments Alessandro hesitated, in regret that he had gone so far with this adventure. He had heard fearful tales of dark deeds committed on the waters of the Bosporus and the Golden Horn; and he himself, when roving during his leisure hours along the verdant banks of those waters, had seen the livid corpse float with the tale-telling bow-string fastened round the neck.

The spy seemed to divine his thoughts.

“You hesitate, signor,” he said; “then let us retrace our way. But remember,” he added in a low tone, “that were treachery intended, it would be as easy to perform the deed where you now stand, as on the bosom of that star-lit gulf.”

Alessandro hesitated no longer, but suffered himself to be completely hooded in a cap which the spy drew over his countenance. He was then conducted into the boat and guided to a seat next to the female slave. The spy leapt upon the strand, the boatmen plied their oars, and the skiff shot away from the bank, no one uttering a word.

CHAPTER XLV.
THE LADY OF CONSTANTINOPLE.

For upward of half an hour did the boat skim the surface of the Golden Horn, the dip of the oars in the water and the rippling around the sharp prow alone breaking the solemn silence of the night. At length the skiff stopped, and the female slave took Alessandro’s hand, whispering in a low tone, “I will serve as thy guide, Christian; but speak not till thou hast permission.”

She then led him from the boat, up a flight of steps, and through a garden—for he occasionally came in contact with the outstretching branches of shrubs, and there was moreover a delicious odor of flowers, as he proceeded in the total darkness of his blindfolding. At the expiration of ten minutes the guide stopped; and Alessandro heard a key turn in a lock.
