At that moment the door of the apartment was violently thrown open, and a young gentleman entered. The Dead Man and the Doctor turned, and in the newcomer recognised Frank Sydney!

It will be necessary to explain the mystery of Frank's sudden appearance at that emergency. A day or two after the suicide of Julia, the body of that wretched woman was picked up by some fisherman, and conveyed to the city, where it was immediately recognized as the lady of Mr. Hedge. The circumstance of her death soon came to the knowledge of our hero; and while he could not help shedding a tear as he thought of her melancholy fate (she had once been his wife, and he had once loved her,) he could not deny to himself that he derived a secret joy from the thought, that now his hopes with reference to Sophia Franklin were not without some foundation. Acting upon this impulse, he had taken the earliest opportunity to call upon the young lady; and at that interview, he had with his customary frankness, related to her his entire history, and concluded his narrative by making her an offer of his hand and heart—and, reader, that honorable offer was accepted with the same frankness with which it was made. On the evening in question, Frank was enjoying one of those charming tete-a-tetes with his Sophia, which all lovers find so delightful, when the agonizing screams of the suffering Josephine brought him to the room, as we have seen, and he found himself, to his astonishment, standing face to face with the Dead Man and the Doctor.

'Why, blood and fury!' cried the former, a gleam of pleasure passing over his horrid features—'here is the very man of all men upon earth, whom I most desired to see. Sydney, you are welcome.'

'What damnable villainy have you been at now?' demanded Frank, recovering his courage and presence of mind, altho' he had reason to believe that he had fallen into the power of his worst enemy in the world.

'What business is that of yours?' growled the Dead Man—'Suffice it for you to know that my next act of villainy will be your assassination.'

Our hero drew a revolver from his pocket, and levelled it at the villain's head, saying—

'Advance but a step towards me, and you are a dead man indeed—Scoundrel! I am no longer a prisoner in your dungeon vaults, but free, and able to protect myself against your brutal cruelty. Though you are aided by the Doctor, whom I once thought my friend, I fear you not, but dare you to do your worst.'

'You are brave, Sydney,' said the Dead Man, with something like a grim of admiration—'but I hate you, and you must die. From the first moment when I met you in the Dark Vaults, to the present time, I have observed something in you that inspires me with a kind of fear—a moral superiority over my malice and hatred that inflames me with jealous rage. Even when you were in my power, undergoing my trials and tortures, I have observed contempt upon your lip and scorn in your eye. I once called you coward—but you are a man of doubtless courage, and by Satan! I have half a mind to shake hands with you and call you friend.'

During this harangue, Frank had unconsciously lowered his pistol, not suspecting that the long speech was merely a ruse of the Dead Man to spring upon him unawares. While he stood in an attitude poorly calculated for defence, the miscreant suddenly, with the quickness of lightning, sprang upon him, and with irresistible force hurled him to the floor.

But our hero received an aid which was as unexpected as it was welcome; for the Doctor threw himself upon the Dead Man, grappled him by the throat, and nearly strangled him. In vain the ruffian struggled—he was in the grasp of an adversary too powerful and too intrepid to be successfully resisted by him. Panting and breathless, he was soon vanquished by his ancient enemy, who, having tied his arms behind him with a strong cord, regarded him with a look of hatred and contempt.
