"I cannot," cried my lady. "I would defy you and kill myself if I dared. Do you know what I am thinking of? It is of the day upon which George Talboys--disappeared! The body of George Talboys lies at the bottom of the old well in the shrubbery beyond the lime walk. He came to me there, goaded me beyond endurance, and I called him a madman and a liar. I was going to leave him when he seized me by the wrist and sought to detain me by force. You yourself saw the bruises. I became mad, and drew the loose iron spindle from the shrunken wood of the windlass. My first husband sank with one horrible cry into the black mouth of the well!" _VI.--The Mystery Cleared Up_ On arrival in London, Robert Audley received a letter from Clara Talboys saying that Luke Marks, the man whom he had saved in the fire at the Castle Inn, was lying at his mother's cottage at Audley, and expressed a very earnest wish to see him. Robert took train at once to Audley. The dying man confessed that on the night of George Talboys's disappearance, when going home to his mother's cottage, he heard groans come from the laurel bushes in the shrubbery near the old well. On search, he found Talboys covered with slime, and with a broken arm. He carried the crippled man to his mother's cottage, washed, fed, and nursed him. Next day Talboys gave him a five-pound note to accompany him to the town of Brentwood, where he called on a surgeon to have his broken arm set and dressed. That done, Talboys wrote two notes in pencil with his left hand, and gave them to Luke to deliver--one with a cross to be handed to Lady Audley, and the other to the nephew of Sir Michael, and then took train to London in a second-class carriage. Phoebe, who had seen from her window Lady Audley pushing George Talboys into the well, said that my lady was in their power, and that she would do anything for them to keep her secret. So the letters were not delivered. He hid them away; not a creature had seen them. The old mother, who had been present throughout the confession, took the papers from a drawer and handed them to Robert Audley. The note to Robert said that something had happened to the writer, he could not tell what, which drove him from England, a broken-hearted man, to seek some corner of the earth where he might live and die unknown and forgotten. He left his son in his friend's hands, knowing that he could leave him to no truer guardian. The second note was addressed "Helen," saying, "May God pity and forgive you for that which you have done to-day, as truly as I do. Rest in peace. You shall never hear from me again. I leave England, never to return.--G. T."
