"On this threshold you told me suddenly that Bludyer was a villain, and had betrayed your sister Aldina; that she had fled with him that night; that he could never marry her, as you had reason to know he had a wife alive. You made me swear to help you in your vengeance against him. We entered the room, as we enter it now."
Our leader had opened the door of the room, and we were in the same chamber I had wandered to when I had slept at The Mere. The figure of Geoffrey Ringwood paused at the round table, and looked again at Mr. Maryon, who proceeded:
"You went straight to the fifth panel from the fireplace, and then touched a spring, and the panel opened. You said that the will giving this property to your father and his heirs was to be found there. I was convinced that you spoke the truth, but, suddenly remembering your love of gambling, I suggested that we should play for it. You accepted at once. We searched among the papers, and found the will. We placed the will upon the table, and began to play. We agreed that we would play up to ten thousand pounds. Your luck was marvellous. In two hours the limit was reached. I owed you ten thousand pounds, and had lost The Mere. You laughed, and said, 'Well, John, you have had a fair chance. At ten o'clock this morning I shall expect you to pay me _your debt of honor_.' I rose; the devil of despair strong upon me. With one hand I swept the cards from the table into the fire, and with the other seized you by the throat, and dealt you a blow upon the temple. You fell dead upon the floor."
Need I say that as I heard this fearful narrative, I recognized the actions of the sleep-walker, and understood them all?
"To the end!" said the hollow voice. "Confess to the end!"
"The doctor who examined your body gave his opinion, at the inquest, that you had died of apoplexy, caused by strong cerebral excitement. My evidence was to the effect that I believed you had lost a very large sum of money to Captain Bludyer, and that you had told me you were utterly unable to pay it. The jury found their verdict accordingly, and I was left in undisturbed possession of The Mere. But the memory of my crime haunted me as only such memories can haunt a criminal, and I became a morose and miserable man. One thing bound me to life--my daughter. When Reginald Westcar appeared upon the scene I thought that the debt of honor would be satisfied if he married Agnes. Then Bludyer reappeared, and he told me that he knew that I had killed you. He threatened to revive the story, to exhume your body, and to say that Aldina Ringwood had told him all about the will. I could purchase his silence only by giving him my daughter, the heiress of The Mere. To this I consented."
