The old cat got up from the bag footstool and stretched itself, and Nurse Macdonald opened her ancient eyes and looked slowly round the room by the dim light of the night lamp. She touched the cat with her crutch-stick, and it lay down upon her feet. She drank a few drops from her cup and went to sleep again. But downstairs Sir Gabriel sat straight up as the clock struck, for he had dreamed a fearful dream of horror, and his heart stood still, till he awoke at its stopping, and it beat again furiously with his breath, like a wild thing set free. No Ockram had ever known fear waking, but sometimes it came to Sir Gabriel in his sleep. He pressed his hands to his temples as he sat up in bed, and his hands were icy cold, but his head was hot. The dream faded far, and in its place there came the master thought that racked his life; with the thought also came the sick twisting of his lips in the dark that would have been a smile. Far off, Evelyn Warburton dreamed that the dead smile was on her mouth, and awoke, starting with a little moan, her face in her hands, shivering. But Sir Gabriel struck a light and got up and began to walk up and down his great room. It was midnight, and he had barely slept an hour, and in the north of Ireland the winter nights are long. "I shall go mad," he said to himself, holding his forehead. He knew that it was true. For weeks and months the possession of the thing had grown upon him like a disease, till he could think of nothing without thinking first of that. And now all at once it outgrew his strength, and he knew that he must be its instrument or lose his mind--that he must do the deed he hated and feared, if he could fear anything, or that something would snap in his brain and divide him from life while he was yet alive. He took the candlestick in his hand, the old-fashioned heavy candlestick that had always been used by the head of the house. He did not think of dressing, but went as he was, in his silk night clothes and his slippers, and he opened the door. Everything was very still in the great old house. He shut the door behind him and walked noiselessly on the carpet through the long corridor. A cool breeze blew over his shoulder and blew the flame of his candle straight out from him. Instinctively he stopped and looked round, but all was still, and the upright flame burned steadily. He walked on, and instantly a strong draught was behind him, almost extinguishing the light. It seemed to blow him on his way, ceasing whenever he turned, coming again when he went on--invisible, icy.
