He returned to his office, and, putting the envelope that had been lying on Slinn's desk in his pocket, threw a serape over his shoulders, and locked the front door of the house behind him. It was well that the way was a familiar one to him, and that his feet instinctively found the trail, for the night was very dark. At times he was warned only by the gurgling of water of little rivulets that descended the hill and crossed his path. Without the slightest fear, and with neither imagination nor sensitiveness, he recalled how, the winter before, one of Don Caesar's vaqueros, crossing this hill at night, had fallen down the chasm of a landslip caused by the rain, and was found the next morning with his neck broken in the gully. Don Caesar had to take care of the man's family. Suppose such an accident should happen to him? Well, he had made his will. His wife and children would be provided for, and the work of the mine would go on all the same; he had arranged for that. Would anybody miss him? Would his wife, or his son, or his daughter? No. He felt such a sudden and overwhelming conviction of the truth of this that he stopped as suddenly as if the chasm had opened before him. No! It was the truth. If he were to disappear forever in the darkness of the Christmas night there was none to feel his loss. His wife would take care of Mamie; his son would take care of himself, as he had before--relieved of even the scant paternal authority he rebelled against. A more imaginative man than Mulrady would have combated or have followed out this idea, and then dismissed it; to the millionaire's matter-of-fact mind it was a deduction that, having once presented itself to his perception, was already a recognized fact. For the first time in his life he felt a sudden instinct of something like aversion towards his family, a feeling that even his son's dissipation and criminality had never provoked. He hurried on angrily through the darkness. It was very strange; the old house should be almost before him now, across the hollow, yet there were no indications of light! It was not until he actually reached the garden fence, and the black bulk of shadow rose out against the sky, that he saw a faint ray of light from one of the lean-to windows. He went to the front door and knocked. After waiting in vain for a reply, he knocked again. The second knock proving equally futile, he tried the door; it was unlocked, and, pushing it open, he walked in. The narrow passage was quite dark, but from his knowledge of the house he knew the "lean-to" was next to the kitchen, and, passing through the dining-room into it, he opened the door of the little room from which the light proceeded. It came from a single candle on a small table, and beside it, with his eyes moodily fixed on the dying embers of the fire, sat old Slinn. There was no other light nor another human being in the whole house.
