The fallen lamp recalled Malcolmson to himself. Fortunately it was of metal, and so the oil was not spilt. However, the practical need of attending to it settled at once his nervous apprehension. When he had turned it out, he wiped his brow and thought for a moment.
"This will not do, " he said to himself. "If I go on like this I shall become a crazy fool. This must stop! I promised the doctor I would not take tea. Faith, he was pretty right! My nerves must have been getting into a queer state. Funny I did not notice it. I never felt better in my life. However, it is all right now, and I shall not be such a fool again."
Then he mixed himself a good stiff glass of brandy and water and resolutely sat down to his work.
It was nearly an hour when he looked up from his book, disturbed by the sudden stillness. Without, the wind howled and roared louder than ever, and the rain drove in sheets against the windows, beating like hail on the glass; but within there was no sound whatever save the echo of the wind as it roared in the great chimney, and now and then a hiss as a few raindrops found their way down the chimney in a lull of the storm. The fire had fallen low and had ceased to flame, though it threw out a red glow. Malcolmson listened attentively, and presently heard a thin, squeaking noise, very faint. It came from the corner of the room where the rope hung down, and he thought it was the creaking of the rope on the floor as the swaying of the bell raised and lowered it. Looking up, however, he saw in the dim light the great rat clinging to the rope and gnawing it. The rope was already nearly gnawed through—he could see the lighter colour where the strands were laid bare. As he looked the job was completed, and the severed end of the rope fell clattering on the oaken floor, whilst for an instant the great rat remained like a knob or tassel at the end of the rope, which now began to sway to and fro. Malcolmson felt for a moment another pang of terror as he thought that now the possibility of calling the outer world to his assistance was cut off, but an intense anger took its place, and seizing the book he was reading he hurled it at the rat. The blow was well aimed, but before the missile could reach him the rat dropped off and struck the floor with a soft thud. Malcolmson instantly rushed over towards him, but it darted away and disappeared in the darkness of the shadows of the room. Malcolmson felt that his work was over for the night, and determined then and there to vary the monotony of the proceedings by a hunt for the rat, and took off the green shade of the lamp so as to insure a wider spreading light. As he did so the gloom of the upper part of the room was relieved, and in the new flood of light, great by comparison with the previous darkness, the pictures on the wall stood out boldly. From where he stood, Malcolmson saw right opposite to him the third picture on the wall from the right of the fireplace. He rubbed his eyes in surprise, and then a great fear began to come upon him.
