As he spoke, seeing that she had moved to go, he came to the door with her, and in the most natural way accompanied her downstairs. He passed through the hall with her and down the avenue. As he went back to the house, she smiled to herself.

“Well, that is all right. I don’t think the morning has been altogether thrown away.”

And she walked slowly back to Diana’s Grove.

Adam Salton followed the line of the Brow, and refreshed his memory as to the various localities. He got home to Lesser Hill just as Sir Nathaniel was beginning lunch. Mr. Salton had gone to Walsall to keep an early appointment; so he was all alone. When the meal was over—seeing in Adam’s face that he had something to speak about—he followed into the study and shut the door.

When the two men had lighted their pipes, Sir Nathaniel began.

“I have remembered an interesting fact about Diana’s Grove—there is, I have long understood, some strange mystery about that house. It may be of some interest, or it may be trivial, in such a tangled skein as we are trying to unravel.”

“Please tell me all you know’ or suspect. To begin, then, of what sort is the mystery—physical, mental, moral, historical, scientific, occult? Any kind of hint will help me.”

“Quite right. I shall try to tell you what I I think; but I have not put my thoughts on the subject in sequence, so you must forgive me if due order is not observed in my narration. I suppose you have seen the house at Diana’s Grove?”

“The outside of it; but I have that in my mind’s eye, and I can fit into my memory whatever you may mention.”

“The house is very old—probably the first house of some sort that stood there was in the time of the Romans. This was probably renewed—perhaps several times at later periods. The house stands, or, rather, used to stand here when Mercia was a kingdom—I do not suppose that the basement can be later than the Norman Conquest. Some years ago, when I was President of the Mercian Archaeological Society, I went all over it very carefully. This was when it was purchased by Captain March. The house had then been done up, so as to be suitable for the bride. The basement is very strong,—almost as strong and as heavy as if it had been intended as a fortress. There are a whole series of rooms deep underground. One of them in particular struck me. The room itself is of considerable size, but the masonry is more than massive. In the middle of the room is a sunk well, built up to floor level and evidently going deep underground. There is no windlass nor any trace of there ever having been any—no rope—nothing. Now, we know that the Romans had wells of immense depth, from which the water was lifted by the ‘old rag rope’; that at Woodhull used to be nearly a thousand feet. Here, then, we have simply an enormously deep well-hole. The door of the room was massive, and was fastened with a lock nearly a foot square. It was evidently intended for some kind of protection to someone or something; but no one in those days had ever heard of anyone having been allowed even to see the room. All this is E PROPOS of a suggestion on my part that the well-hole was a way by which the White Worm (whatever it was) went and came. At that time I would have had a search made—even excavation if necessary—at my own expense, but all suggestions were met with a prompt and explicit negative. So, of course, I took no further step in the matter. Then it died out of recollection—even of mine.”

The night was hot, and the shop, close shut and surrounded by so foul a neighbourhood, was ill–smelling. Monsieur Defarge’s olfactory sense was by no means delicate, but the stock of wine smelt much stronger than it ever tasted, and so did the stock of rum and brandy and aniseed. He whiffed the compound of scents away, as he put down his smoked–out pipe.

“You are fatigued,” said madame, raising her glance as she knotted the money. “There are only the usual odours.”

“I am a little tired,” her husband acknowledged.

“You are a little depressed, too,” said madame, whose quick eyes had never been so intent on the accounts, but they had had a ray or two for him. “Oh, the men, the men!”

“But my dear!” began Defarge.

“But my dear!” repeated madame, nodding firmly; “but my dear! You are faint of heart to–night, my dear!”

“Well, then,” said Defarge, as if a thought were wrung out of his breast, “it IS a long time.”

“It is a long time,” repeated his wife; “and when is it not a long time? Vengeance and retribution require a long time; it is the rule.”

“It does not take a long time to strike a man with Lightning,” said Defarge.

“How long,” demanded madame, composedly, “does it take to make and store the lightning? Tell me.”

Defarge raised his head thoughtfully, as if there were something in that too.

“It does not take a long time,” said madame, “for an earthquake to swallow a town. Eh well! Tell me how long it takes to prepare the earthquake?”

“A long time, I suppose,” said Defarge.

“But when it is ready, it takes place, and grinds to pieces everything before it. In the meantime, it is always preparing, though it is not seen or heard. That is your consolation. Keep it.”

She tied a knot with flashing eyes, as if it throttled a foe.

“I tell thee,” said madame, extending her right hand, for emphasis, “that although it is a long time on the road, it is on the road and coming. I tell thee it never retreats, and never stops. I tell thee it is always advancing. Look around and consider the lives of all the world that we know, consider the faces of all the world that we know, consider the rage and discontent to which the Jacquerie addresses itself with more and more of certainty every hour. Can such things last? Bah! I mock you.”

“My brave wife,” returned Defarge, standing before her with his head a little bent, and his hands clasped at his back, like a docile and attentive pupil before his catechist, “I do not question all this. But it has lasted a long time, and it is possible—you know well, my wife, it is possible—that it may not come, during our lives.”

“Eh well! How then?” demanded madame, tying another knot, as if there were another enemy strangled.

“Well!” said Defarge, with a half complaining and half apologetic shrug. “We shall not see the triumph.”
