“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 that is implied by them and by their mutual 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?”

“Don’t look!” cried Mr. Lorry, absolutely desperate. “No, Lucie, my dear, nor you!” He got his arm round her, and held her. “Don’t be so terrified, my love. I solemnly swear to you that I know of no harm having happened to Charles; that I had no suspicion even of his being in this fatal place. What prison is he in?”

“La Force!”

“La Force! Lucie, my child, if ever you were brave and serviceable in your life—and you were always both—you will compose yourself now, to do exactly as I bid you; for more depends upon it than you can think, or I can say. There is no help for you in any action on your part to–night; you cannot possibly stir out. I say this, because what I must bid you to do for Charles’s sake, is the hardest thing to do of all. You must instantly be obedient, still, and quiet. You must let me put you in a room at the back here. You must leave your father and me alone for two minutes, and as there are Life and Death in the world you must not delay.”

“I will be submissive to you. I see in your face that you know I can do nothing else than this. I know you are true.”

The old man kissed her, and hurried her into his room, and turned the key; then, came hurrying back to the Doctor, and opened the window and partly opened the blind, and put his hand upon the Doctor’s arm, and looked out with him into the courtyard.

Looked out upon a throng of men and women: not enough in number, or near enough, to fill the courtyard: not more than forty or fifty in all. The people in possession of the house had let them in at the gate, and they had rushed in to work at the grindstone; it had evidently been set up there for their purpose, as in a convenient and retired spot.

But, such awful workers, and such awful work!

The grindstone had a double handle, and, turning at it madly were two men, whose faces, as their long hair Rapped back when the whirlings of the grindstone brought their faces up, were more horrible and cruel than the visages of the wildest savages in their most barbarous disguise. False eyebrows and false moustaches were stuck upon them, and their hideous countenances were all bloody and sweaty, and all awry with howling, and all staring and glaring with beastly excitement and want of sleep. As these ruffians turned and turned, their matted locks now flung forward over their eyes, now flung backward over their necks, some women held wine to their mouths that they might drink; and what with dropping blood, and what with dropping wine, and what with the stream of sparks struck out of the stone, all their wicked atmosphere seemed gore and fire. The eye could not detect one creature in the group free from the smear of blood. Shouldering one another to get next at the sharpening–stone, were men stripped to the waist, with the stain all over their limbs and bodies; men in all sorts of rags, with the stain upon those rags; men devilishly set off with spoils of women’s lace and silk and ribbon, with the stain dyeing those trifles through and through. Hatchets, knives, bayonets, swords, all brought to be sharpened, were all red with it. Some of the hacked swords were tied to the wrists of those who carried them, with strips of linen and fragments of dress: ligatures various in kind, but all deep of the one colour. And as the frantic wielders of these weapons snatched them from the stream of sparks and tore away into the streets, the same red hue was red in their frenzied eyes;—eyes which any unbrutalised beholder would have given twenty years of life, to petrify with a well–directed gun.
