Crossing the square, the officer led the way towards a small door in one of the angles of the immense edifice. Mario knocked gently; and the door was immediately opened by a tall servant in a gorgeous livery. Markham followed his companion into a small vestibule, brilliantly lighted, and at the end of which was a narrow staircase carpetted all over. Not a word was spoken: the domestic bowed as the two young men passed him; and Bazzano led the way up the staircase, which was lighted by lamps held in the hands of marble statues placed in recesses. On the landing which the visitors speedily reached, an usher, dressed in black, and wearing a massive gold chain, advanced to receive them; and, opening a door, conducted them into an ante-room, where he requested them to be seated. He then opened another door on the opposite side from which they had entered the room, and disappeared for a few minutes. On his return, he desired Markham to follow him. Our hero obeyed, and was led through several magnificent apartments, all brilliantly lighted, but unoccupied at the moment. At length the usher paused in a room smaller, but more elegantly furnished, than any of the preceding ones; and, having requested our hero to take a seat, he retired by the same door by which they had entered that room. For a few minutes Richard remained alone with his reflections. He was now in the Castelcicalan palace. But wherefore had he been brought thither? Was it to undergo an examination before the Grand Duke, relative to the invasion of the morning? was it to be overwhelmed with reproaches by that sovereign against whom, and without provocation, he had borne arms? Could treachery be meditated? No—that idea was absurd. He was so completely in the power of the Grand Duke, that there had been no need to exercise treachery towards him, if punishment were intended. Then our hero thought of the Grand Duchess. Had she learnt that he was engaged in the expedition? had she remembered his name? was it through her he had received that treatment from Mario Bazzano which had so astonished him? could it be possible that she would interest herself in him? He was in the midst of his reverie, when a door opposite to where he was sitting, suddenly opened; and a lady, elegantly attired, with a tiara of diamonds upon her brow, entered the apartment. One glance was sufficient for Richard Markham! He immediately recognised the beautiful woman whom he had seen five years previously, disguised in male attire, at Mrs. Arlington's lodgings, and whose singular history had subsequently reached his ears when he was imprisoned at the same time as herself, though of course not in the same department, in Newgate. Yes—he recognised _her_ who was once Eliza Sidney; and he now bent his head to the grand Duchess of Castelcicala.
