How busy they were! and hark to the strange noises! Up and down behind the old wainscot, over the ceiling and under the floor they raced, and gnawed, and scratched! Malcolmson smiled to himself as he recalled to mind the saying of Mrs. Dempster, “Bogies is rats, and rats is bogies!” The tea began to have its effect of intellectual and nervous stimulus, he saw with joy another long spell of work to be done before the night was past, and in the sense of security which it gave him, he allowed himself the luxury of a good look round the room. He took his lamp in one hand, and went all around, wondering that so quaint and beautiful an old house had been so long neglected. The carving of the oak on the panels of the wainscot was fine, and on and round the doors and windows it was beautiful and of rare merit. There were some old pictures on the walls, but they were coated so thick with dust and dirt that he could not distinguish any detail of them, though he held his lamp as high as he could over his head. Here and there as he went round he saw some crack or hole blocked for a moment by the face of a rat with its bright eyes glittering in the light, but in an instant it was gone, and a squeak and a scamper followed. The thing that most struck him, however, was the rope of the great alarm bell on the roof, which hung down in a corner of the room on the right-hand side of the fireplace. He pulled up close to the hearth a great high-backed carved oak chair, and sat down to his last cup of tea. When this was done he made up the fire, and went back to his work, sitting at the corner of the table, having the fire to his left. For a little while the rats disturbed him somewhat with their perpetual scampering, but he got accustomed to the noise as one does to the ticking of a clock or to the roar of moving water; and he became so immersed in his work that everything in the world, except the problem which he was trying to solve, passed away from him. He suddenly looked up, his problem was still unsolved, and there was in the air that sense of the hour before the dawn, which is so dread to doubtful life. The noise of the rats had ceased. Indeed it seemed to him that it must have ceased but lately and that it was the sudden cessation which had disturbed him. The fire had fallen low, but still it threw out a deep red glow. As he looked he started in spite of his _sang froid_. There on the great high-backed carved oak chair by the right side of the fireplace sat an enormous rat, steadily glaring at him with baleful eyes. He made a motion to it as though to hunt it away, but it did not stir. Then he made the motion of throwing something. Still it did not stir, but showed its great white teeth angrily, and its cruel eyes shone in the lamplight with an added vindictiveness.
