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 of his lamp left the upper part of the room in darkness, and the fire had burned low.

On looking at his watch he found it was close on midnight; and, not sorry for the divertissement, he made up his fire and made himself his nightly pot of tea. He had got through a good spell of work, and thought himself entitled to a cigarette; and so he sat on the great oak chair before the fire and enjoyed it. Whilst smoking he began to think that he would like to know where the rat disappeared to, for he had certain ideas for the morrow not entirely disconnected with a rat-trap. Accordingly he lit another lamp and placed it so that it would shine well into the right-hand corner of the wall by the fireplace. Then he got all the books he had with him, and placed them handy to throw at the vermin. Finally he lifted the rope of the alarm bell and placed the end of it on the table, fixing the extreme end under the lamp. As he handled it he could not help noticing how pliable it was, especially for so strong a rope, and one not in use. 'You could hang a man with it,' he thought to himself. When his preparations were made he looked around, and said complacently:

'There now, my friend, I think we shall learn something of you this time!' He began his work again, and though as before somewhat disturbed at first by the noise of the rats, soon lost himself in his propositions and problems.

Again he was called to his immediate surroundings suddenly. This time it might not have been the sudden silence only which took his attention; there was a slight movement of the rope, and the lamp moved. Without stirring, he looked to see if his pile of books was within range, and then cast his eye along the rope. As he looked he saw the great rat drop from the rope on the oak arm-chair and sit there glaring at him. He raised a book in his right hand, and taking careful aim, flung it at the rat. The latter, with a quick movement, sprang aside and dodged the missile. He then took another book, and a third, and flung them one after another at the rat, but each time unsuccessfully. At last, as he stood with a book poised in his hand to throw, the rat squeaked and seemed afraid. This made Malcolmson more than ever eager to strike, and the book flew and struck the rat a resounding blow. It gave a terrified squeak, and turning on his pursuer a look of terrible malevolence, ran up the chair-back and made a great jump to the rope of the alarm bell and ran up it like lightning. The lamp rocked under the sudden strain, but it was a heavy one and did not topple over. Malcolmson kept his eyes on the rat, and saw it by the light of the second lamp leap to a moulding of the wainscot and disappear through a hole in one of the great pictures which hung on the wall, obscured and invisible through its coating of dirt and dust.

'I shall look up my friend's habitation in the morning,' said the student, as he went over to collect his books. 'The third picture from the fireplace; I shall not forget.' He picked up the books one by one, commenting on them as he lifted them. 'Conic Sections he does not mind, nor Cycloidal Oscillations, nor the Principia, nor Quaternions, nor Thermodynamics. Now for the book that fetched him!' Malcolmson took it up and looked at it. As he did so he started, and a sudden pallor overspread his face. He looked round uneasily and shivered slightly, as he murmured to himself:

'The Bible my mother gave me! What an odd coincidence.' He sat down to work again, and the rats in the wainscot renewed their gambols. They did not disturb him, however; somehow their presence gave him a sense of companionship. But he could not attend to his work, and after striving to master the subject on which he was engaged gave it up in despair, and went to bed as the first streak of dawn stole in through the eastern window.

He slept heavily but uneasily, and dreamed much; and when Mrs. Dempster woke him late in the morning he seemed ill at ease, and for a few minutes did not seem to realise exactly where he was. His first request rather surprised the servant.

'Mrs. Dempster, when I am out to-day I wish you would get the steps and dust or wash those pictures—specially that one the third from the fireplace—I want to see what they are.'

Late in the afternoon Malcolmson worked at his books in the shaded walk, and the cheerfulness of the previous day came back to him as the day wore on, and he found that his reading was progressing well. He had worked out to a satisfactory conclusion all the problems which had as yet baffled him, and it was in a state of jubilation that he paid a visit to Mrs. Witham at 'The Good Traveller'. He found a stranger in the cosy sitting-room with the landlady, who was introduced to him as Dr. Thornhill. She was not quite at ease, and this, combined with the doctor's plunging at once into a series of questions, made Malcolmson come to the conclusion that his presence was not an accident, so without preliminary he said:

'Dr. Thornhill, I shall with pleasure answer you any question you may choose to ask me if you will answer me one question first.'

The doctor seemed surprised, but he smiled and answered at once, 'Done! What is it?'

'Did Mrs. Witham ask you to come here and see me and advise me?'

Dr. Thornhill for a moment was taken aback, and Mrs. Witham got fiery red and turned away; but the doctor was a frank and ready man, and he answered at once and openly.

'She did: but she didn't intend you to know it. I suppose it was my clumsy haste that made you suspect. She told me that she did not like the idea of your being in that house all by yourself, and that she thought you took too much strong tea. In fact, she wants me to advise you if possible to give up the tea and the very late hours. I was a keen student in my time, so I suppose I may take the liberty of a college man, and without offence, advise you not quite as a stranger.'

Malcolmson with a bright smile held out his hand. 'Shake! as they say in America,' he said. 'I must thank you for your kindness and Mrs. Witham too, and your kindness deserves a return on my part. I promise to take no more strong tea—no tea at all till you let me—and I shall go to bed tonight at one o'clock at latest. Will that do?'

'Capital,' said the doctor. 'Now tell us all that you noticed in the old house,' and so Malcolmson then and there told in minute detail all that had happened in the last two nights. He was interrupted every now and then by some exclamation from Mrs. Witham, till finally when he told of the episode of the Bible the landlady's pent-up emotions found vent in a shriek; and it was not till a stiff glass of brandy and water had been administered that she grew composed again. Dr. Thornhill listened with a face of growing gravity, and when the narrative was complete and Mrs. Witham had been restored he asked:

'The rat always went up the rope of the alarm bell?'

'Always.'

'I suppose you know,' said the Doctor after a pause, 'what the rope is?'

'No!'

'It is,' said the Doctor slowly, 'the very rope which the hangman used for all the victims of the Judge's judicial rancour!'
