Even as they were talking, a knocking was heard at the hall-door, and after a brief and hurried consultation, it was agreed, that, considering the strict condition of privacy attached to this visit by Mr. Marston himself, as well as his reserved and wayward temper, it might be better for Charles to avoid presenting himself to his father on this occasion. A few seconds afterwards the door opened, and Mr. Marston entered the apartment. It was now dark, and the servant, unbidden, placed candles upon the table. Without answering one word to Dr. Danvers' greeting, Marston sat down, as it seemed, in agitated abstraction. Removing his hat suddenly (for he had not even made this slight homage to the laws of courtesy), he looked round with a care-worn, fiery eye, and a pale countenance, and said—
"We are quite alone, Dr. Danvers—no one anywhere near?"
Dr. Danvers assured him that all was secure. After a long and agitated pause, Marston said—
"You remember Merton's confession. He admitted his intention to kill Berkley, but denied that he was the actual murderer. He spoke truth—no one knew it better than I; for I am the murderer."
Dr. Danvers was so shocked and overwhelmed that he was utterly unable to speak.
"Aye, sir, in point of law and of morals, literally and honestly, the murderer of Wynston Berkley. I am resolved you shall know it all. Make what use of it you will—I care for nothing now, but to get rid of the d——d, unsustainable secret, and that is done. I did not intend to kill the scoundrel when I went to his room; but with the just feelings of exasperation with which I regarded him, it would have been wiser had I avoided the interview; and I meant to have done so. But his candle was burning; I saw the light through the door, and went in. It was his evil fortune to indulge in his old strain of sardonic impertinence. He provoked me; I struck him—he struck me again—and with his own dagger I stabbed him three times. I did not know what I had done; I could not believe it. I felt neither remorse nor sorrow—why should I?—but the thing was horrible, astounding. There he sat in the corner of his cushioned chair, with the old fiendish smile on still. Sir, I never thought that any human shape could look so dreadful. I don't know how long I stayed there, freezing with horror and detestation, and yet unable to take my eyes from the face. Did you see it in the coffin? Sir, there was a sneer of triumph on it that was diabolic and prophetic."
Marston was fearfully agitated as he spoke, and repeatedly wiped from his face the cold sweat that gathered there.
"I could not leave the room by the back stairs," he resumed, "for the valet slept in the intervening chamber. I felt such an appalled antipathy to the body, that I could scarcely muster courage to pass it. But, sir, I am not easily cowed—I mastered this repugnance in a few minutes—or, rather, I acted spite of it, I knew not how; but instinctively it seemed to me that it was better to lay the body in the bed, than leave it where it was, shewing, as its position might, that the thing occurred in an altercation. So, sir, I raised it, and bore it softly across the room, and laid it in the bed; and, while I was carrying it, it swayed forward, the arms glided round my neck, and the head rested against my cheek—that was a parody upon a brotherly embrace!
"I do not know at what moment it was, but some time when I was carrying Wynston, or laying him in the bed," continued Marston, who spoke rather like one pursuing a horrible reverie, than as a man relating facts to a listener, "I heard a light tread, and soft breathing in the lobby. A thunderclap would have stunned me less that minute. I moved softly, holding my breath, to the door. I believe, in moments of strong excitement, men hear more acutely than at other times; but I thought I heard the rustling of a gown, going from the door again. I waited—it ceased; I waited until all was quiet. I then extinguished the candle, and groped my way to the door; there was a faint light in the corridor, and I thought I saw a head projected from the chamber-door, next to the Frenchwoman's—mademoiselle's. As I came on, it was softly withdrawn, and the door not quite noiselessly closed. I could not be absolutely certain, but I learned all afterward. And now, sir, you have the story of Sir Wynston's murder."
Dr. Danvers groaned in spirit, being wrung alike with fear and sorrow. With hands clasped, and head bowed down, in an exceeding bitter agony of soul, he murmured only the words of the Litany—"Lord, have mercy upon us; Christ, have mercy upon us; Lord, have mercy upon us."
