'Surely,' he thought, 'they cannot have been at it all the time I was reading. Had they been, I must have noticed it!' Presently, when the noise increased, he satisfied himself that it was really new. It was evident that at first the rats had been frightened at the presence of a stranger, and the light of fire and lamp; but that as the time went on they had grown bolder and were now disporting themselves as was their wont.
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.
Malcolmson felt amazed, and seizing the poker from the hearth ran at it to kill it. Before, however, he could strike it, the rat, with a squeak that sounded like the concentration of hate, jumped upon the floor, and, running up the rope of the alarm bell, disappeared in the darkness beyond the range of the green-shaded lamp. Instantly, strange to say, the noisy scampering of the rats in the wainscot began again.
By this time Malcolmson's mind was quite off the problem; and as a shrill cock-crow outside told him of the approach of morning, he went to bed and to sleep.
He slept so sound that he was not even waked by Mrs. Dempster coming in to make up his room. It was only when she had tidied up the place and got his breakfast ready and tapped on the screen which closed in his bed that he woke. He was a little tired still after his night's hard work, but a strong cup of tea soon freshened him up and, taking his book, he went out for his morning walk, bringing with him a few sandwiches lest he should not care to return till dinner time. He found a quiet walk between high elms some way outside the town, and here he spent the greater part of the day studying his Laplace. On his return he looked in to see Mrs. Witham and to thank her for her kindness. When she saw him coming through the diamond-paned bay window of her sanctum she came out to meet him and asked him in. She looked at him searchingly and shook her head as she said:
'You must not overdo it, sir. You are paler this morning than you should be. Too late hours and too hard work on the brain isn't good for any man! But tell me, sir, how did you pass the night? Well, I hope? But my heart! sir, I was glad when Mrs. Dempster told me this morning that you were all right and sleeping sound when she went in.'
'Oh, I was all right,' he answered smiling, 'the "somethings" didn't worry me, as yet. Only the rats; and they had a circus, I tell you, all over the place. There was one wicked looking old devil that sat up on my own chair by the fire, and wouldn't go till I took the poker to him, and then he ran up the rope of the alarm bell and got to somewhere up the wall or the ceiling—I couldn't see where, it was so dark.'
'Mercy on us,' said Mrs. Witham, 'an old devil, and sitting on a chair by the fireside! Take care, sir! take care! There's many a true word spoken in jest.'
'How do you mean? Pon my word I don't understand.'
'An old devil! The old devil, perhaps. There! sir, you needn't laugh,' for Malcolmson had broken into a hearty peal. 'You young folks thinks it easy to laugh at things that makes older ones shudder. Never mind, sir! never mind! Please God, you'll laugh all the time. It's what I wish you myself!' and the good lady beamed all over in sympathy with his enjoyment, her fears gone for a moment.
'Oh, forgive me!' said Malcolmson presently. 'Don't think me rude; but the idea was too much for me—that the old devil himself was on the chair last night!' And at the thought he laughed again. Then he went home to dinner.
This evening the scampering of the rats began earlier; indeed it had been going on before his arrival, and only ceased whilst his presence by its freshness disturbed them. After dinner he sat by the fire for a while and had a smoke; and then, having cleared his table, began to work as before. Tonight the rats disturbed him more than they had done on the previous night. How they scampered up and down and under and over! How they squeaked, and scratched, and gnawed! How they, getting bolder by degrees, came to the mouths of their holes and to the chinks and cracks and crannies in the wainscoting till their eyes shone like tiny lamps as the firelight rose and fell. But to him, now doubtless accustomed to them, their eyes were not wicked; only their playfulness touched him. Sometimes the boldest of them made sallies out on the floor or along the mouldings of the wainscot. Now and again as they disturbed him Malcolmson made a sound to frighten them, smiting the table with his hand or giving a fierce 'Hsh, hsh,' so that they fled straightway to their holes.
And so the early part of the night wore on; and despite the noise Malcolmson got more and more immersed in his work.
All at once he stopped, as on the previous night, being overcome by a sudden sense of silence. There was not the faintest sound of gnaw, or scratch, or squeak. The silence was as of the grave. He remembered the odd occurrence of the previous night, and instinctively he looked at the chair standing close by the fireside. And then a very odd sensation thrilled through him.
There, on the great old high-backed carved oak chair beside the fireplace sat the same enormous rat, steadily glaring at him with baleful eyes.
Instinctively he took the nearest thing to his hand, a book of logarithms, and flung it at it. The book was badly aimed and the rat did not stir, so again the poker performance of the previous night was repeated; and again the rat, being closely pursued, fled up the rope of the alarm bell. Strangely too, the departure of this rat was instantly followed by the renewal of the noise made by the general rat community. On this occasion, as on the previous one, Malcolmson could not see at what part of the room the rat disappeared, for the green shade
