"And what is his name?"

"That is precisely what I desire to find out," I answered. "When did you see him? How did you identify him? Why did--"

"I have something to tell you, if you will only be quiet, and let me speak," he interrupted. "It was, as you know, late last night before I left here, and for that reason, and also because I was perplexed and troubled, I walked fast--faster than even is my wont. The road was very lonely; I scarcely met a creature along the road, flooded with the moonlight. I never was out on a lovelier night; I had never, even in the country, felt I had it so entirely to myself.

"Every here and there I came within sight of the river, and it seemed, on each occasion, as though a great mirror had been put up to make every object on land--every house, every tree, bush, fern, more clearly visible than it had been before. I am coming to my story, Hal, so don't look so impatient.

"At last, as I came once again in view of the Thames, with the moon reflected in the water, and the dark arches of the bridge looking black and solemn contrasted against the silvery stream, I saw before me, a long way before me, a man whose figure stood out in relief against the white road--a man walking wearily and with evident difficulty--a man, too, slightly deformed.

"I walked on rapidly, till within about a score yards of him, then I slackened my speed, and taking care that my leisurely footsteps should be heard, overtook him by degrees, and then, when I was quite abreast, asked if he could oblige me with a light.

"He looked up in my face, and said, with a forced, painful smile and studied courtesy of manner:

"'I am sorry, sir, to say that I do not smoke.'

"I do not know exactly what reply I made. I know his countenance struck me so forcibly, it was with difficulty I could utter some commonplace remark concerning the beauty of the night.

"'I do not like moonlight,' he said, and as he said it, something, a connection of ideas, or a momentary speculation, came upon me so suddenly, that once again I failed to reply coherently, but asked if he could tell me the shortest way to the Brompton Road.

"'To which end?' he inquired.

"'That nearest Hyde Park Corner,' I answered.

"As it turned out, no question could have served my purpose better.

"'I am going part of the way there,' he said, 'and will show you the nearest route--that is,' he added, 'if you can accommodate your pace to mine,' and he pointed, as he spoke, to his right foot, which evidently was causing him considerable pain.

"Now, that was something quite in my way, and by degrees I got him to tell me about the accident which had caused his slight deformity. I told him I was a doctor, and had been to see a patient, and so led him on to talk about sickness and disease, till at length he touched upon diseases of a morbid character; asking me if it were true that in some special maladies the patient was haunted by an apparition which appeared at a particular hour.

"I told him it was quite true, and that such cases were peculiarly distressing, and generally proved most difficult to cure--mentioning several well-authenticated instances, which I do not mean to detail to you, Patterson, as I know you have an aversion to anything savouring of medical shop.

"'You doctors do not believe in the actual existence of any such apparitions, of course?' he remarked, after a pause.

"I told him we did not; that we knew they had their rise and origin solely in the malady of the patient.

"'And yet,' he said, 'some ghost stories--I am not now speaking of those a.s.sociated with disease, are very extraordinary, unaccountable--'

"'Very extraordinary, no doubt,' I answered; 'but I should hesitate before saying unaccountable. Now, there is that River Hall place up the river. There must be some rational way of explaining the appearances in that house, though no one has yet found any clue to that enigma.'

"'River Hall--where is that?' he asked; then suddenly added, 'Oh! I remember now: you mean the Uninhabited House, as it is called. Yes, there is a curious story, if you like. May I ask if you are interested in any way in that matter?'

"'Not in any way, except that I have been spending the evening there with a friend of mine.'

"'Has he seen anything of the reputed ghost?' asked my companion, eagerly. 'Is he able to throw any light on the dark subject?'

"'I don't think he can,' I replied. 'He has seen the usual appearances which I believe it is correct to see at River Hall; but so far, they have added nothing to his previous knowledge.'

"'He has seen, you say?'

"'Yes; all the orthodox lions of that cheerful house.'

"'And still he is not daunted--he is not afraid?'

"'He is not afraid. Honestly, putting ghosts entirely on one side, I should not care to be in his shoes, all alone in a lonely house.'

"'And you would be right, sir,' was the answer. 'A man must be mad to run such a risk.'

"'So I told him,' I agreed.

"'Why, I would not stay in that house alone for any money which could be offered to me,' he went on, eagerly.

"'I cannot go so far as that,' I said; 'but still it must be a very large sum which could induce me to do so.'

"'It ought to be pulled down, sir,' he continued; 'the walls ought to be razed to the ground.'

"'I suppose they will,' I answered, 'when Miss Elmsdale, the owner, comes of age; unless, indeed, our modern Don Quixote runs the ghost to earth before that time.'

"'Did you say the young man was ill?' asked my companion.

"'He has got a cold,' I answered.

"'And colds are nasty things to get rid of,' he commented, 'particularly in those low-lying localities. That is a most unhealthy part; you ought to order your patient a thorough change of air.'

"'I have, but he won't take advice,' was my reply. 'He has nailed his colours to the mast, and means, I believe, to stay in River Hall till he kills the ghost, or the ghost kills him.'

"'What a foolish youth!'

"'Undoubtedly; but, then, youth is generally foolish, and we have all our crotchets.'

"We had reached the other side of the bridge by this time, and saying his road lay in an opposite direction to mine, the gentleman I have sketched told me the nearest way to take, and bade me a civil good night, adding, 'I suppose I ought to say good morning.'"

"And is that all?" I asked, as Munro paused.

"Bide a wee, as the Scotch say, my son. I strode off along the road he indicated, and then, instead of making the detour he had kindly sketched out for my benefit, chose the first turning to my left, and, quite convinced he would soon pa.s.s that way, took up my position in the portico of a house which lay well in shadow. It stood a little back from the side-path, and a poor little Arab sleeping on the stone step proved to me the policeman was not over and above vigilant in that neighbourhood.

"I waited, Heaven only knows how long, thinking all the time I must be mistaken, and that his home did lie in the direction he took; but at last, looking out between the pillars and the concealing shrubs, I saw him. He was looking eagerly into the distance, with such a drawn, worn, painful expression, that for a moment my heart relented, and I thought I would let the poor devil go in peace.

"It was only for a moment, however; touching the sleeping boy, I bade him awake, if he wanted to earn a shilling. 'Keep that gentleman in sight, and get to know for me where he lives, and come back here, and I will give you a shilling, and perhaps two, for your pains.'

"With his eyes still heavy with slumber, and his perceptions for the moment dulled, he sped after the figure, limping wearily on. I saw him ask my late companion for charity, and follow the gentleman for a few steps, when the latter, threatening him with his stick, the boy dodged to escape a blow, and then, by way of showing how lightly his bosom's load sat upon him, began turning wheels down the middle of the street.

He pa.s.sed the place where I stood, and spun a hundred feet further on, then he gathered himself together, and seeing no one in sight, stealthily crept back to his porch again.

"'You young rascal,' I said, 'I told you to follow him home. I want to know his name and address particularly.'

"'Come along, then,' he answered, 'and I'll show you. Bless you, we all knows him--better than we do the police, or anybody hereabouts. He's a beak and a ward up at the church, whatever that is, and he has building-yards as big, oh! as big as two workhouses, and--'"

"His name, Munro--his name?" I gasped.
