“Of course it might, and probably was. I never thought of that. Is there any possible way of guessing approximately how long a scent will remain? You see, this is a natural scent, and may derive from a place where it has been effective for thousands of years. Then, does a scent of any kind carry with it any form or quality of another kind, either good or evil? I ask you because one ancient name of the house lived in by the lady who was attacked by the mongoose was ‘The Lair of the White Worm.’ If any of these things be so, our difficulties have multiplied indefinitely. They may even change in kind. We may get into moral entanglements; before we know it, we may be in the midst of a struggle between good and evil.”

Sir Nathaniel smiled gravely.

“With regard to the first question—so far as I know, there are no fixed periods for which a scent may be active—I think we may take it that that period does not run into thousands of years. As to whether any moral change accompanies a physical one, I can only say that I have met no proof of the fact. At the same time, we must remember that ‘good’ and ‘evil’ are terms so wide as to take in the whole scheme of creation, and all all that is implied by them and by their mutual action and reaction. Generally, I would say that in the scheme of a First Cause anything is possible. So long as the inherent forces or tendencies of any one thing are veiled from us we must expect mystery.”

“There is one other question on which I should like to ask your opinion. Suppose that there are any permanent forces appertaining to the past, what we may call ‘survivals,’ do these belong to good as well as to evil? For instance, if the scent of the primaeval monster can so remain in proportion to the original strength, can the same be true of things of good import?”

Sir Nathaniel thought for a while before he answered.

“We must be careful not to confuse the physical and the moral. I can see that already you have switched on the moral entirely, so perhaps we had better follow it up first. On the side of the moral, we have certain justification for belief in the utterances of revealed religion. For instance, ‘the effectual fervent prayer of a righteous man availeth much’ is altogether for good. We have nothing of a similar kind on the side of evil. But if we accept this dictum we need have no more fear of ‘mysteries’: these become thenceforth merely obstacles.”

Adam suddenly changed to another phase of the subject.

“And now, sir, may I turn for a few minutes to purely practical things, or rather to matters of historical fact?”

Sir Nathaniel bowed acquiescence.

“We have already spoken of the history, so far as it is known, of some of the places round us—‘Castra Regis,’ ‘Diana’s Grove,’ and ‘The Lair of the White Worm.’ I would like to ask if there is anything not necessarily of evil import about any of the places?”

“I saw this, within the first minute of my contemplation of the patient; for, in her restless strivings she had turned over on her face on the edge of the bed, had drawn the end of the scarf into her mouth, and was in danger of suffocation. My first act was to put out my hand to relieve her breathing; and in moving the scarf aside, the embroidery in the corner caught my sight.

“I turned her gently over, placed my hands upon her breast to calm her and keep her down, and looked into her face. Her eyes were dilated and wild, and she constantly uttered piercing shrieks, and repeated the words, ‘My husband, my father, and my brother!’ and then counted up to twelve, and said, ‘Hush!’ For an instant, and no more, she would pause to listen, and then the piercing shrieks would begin again, and she would repeat the cry, ‘My husband, my father, and my brother!’ and would count up to twelve, and say, ‘Hush!’ There was no variation in the order, or the manner. There was no cessation, but the regular moment’s pause, in the utterance of these sounds.

“‘How long,’ I asked, ‘has this lasted?’

“To distinguish the brothers, I will call them the elder and the younger; by the elder, I mean him who exercised the most authority. It was the elder who replied, ‘Since about this hour last night.’

“‘She has a husband, a father, and a brother?’

“‘A brother.’

“‘I do not address her brother?’

“He answered with great contempt, ‘No.’

“‘She has some recent association with the number twelve?’

“The younger brother impatiently rejoined, ‘With twelve o’clock?’

“‘See, gentlemen,’ said I, still keeping my hands upon her breast, ‘how useless I am, as you have brought me! If I had known what I was coming to see, I could have come provided. As it is, time must be lost. There are no medicines to be obtained in this lonely place.’

“The elder brother looked to the younger, who said haughtily, ‘There is a case of medicines here;’ and brought it from a closet, and put it on the table.

“I opened some of the bottles, smelt them, and put the stoppers to my lips. If I had wanted to use anything save narcotic medicines that were poisons in themselves, I would not have administered any of those.

“‘Do you doubt them?’ asked the younger brother.

“‘You see, monsieur, I am going to use them,’ I replied, and said no more.

“I made the patient swallow, with great difficulty, and after many efforts, the dose that I desired to give. As I intended to repeat it after a while, and as it was necessary to watch its influence, I then sat down by the side of the bed. There was a timid and suppressed woman in attendance (wife of the man down–stairs), who had retreated into a corner. The house was damp and decayed, indifferently furnished—evidently, recently occupied and temporarily used. Some thick old hangings had been nailed up before the windows, to deaden the sound of the shrieks. They continued to be uttered in their regular succession, with the cry, ‘My husband, my father, and my brother!’ the counting up to twelve, and ‘Hush!’ The frenzy was so violent, that I had not unfastened the bandages restraining the arms; but, I had looked to them, to see that they were not painful. The only spark of encouragement in the case, was, that my hand upon the sufferer’s breast had this much soothing influence, that for minutes at a time it tranquillised the figure. It had no effect upon the cries; no pendulum could be more regular.
