Sir Nathaniel had taken care to have the doors and windows shut and locked—all but the door used for their entry. The shutters were up and the blinds down. Moreover, heavy curtains were drawn across the windows. When Adam commented on this, Sir Nathaniel said in a whisper:

“Wait till we are alone, and I’ll tell you why this is done; in the meantime not a word or a sign. You will approve when we have had a talk together.”

They said no more on the subject till after dinner, when they were ensconced in Sir Nathaniel’s study, which was on the top storey. Doom Tower was a lofty structure, situated on an eminence high up in the Peak. The top commanded a wide prospect, ranging from the hills above the Ribble to the near side of the Brow, which marked the northern bound of ancient Mercia. It was of the early Norman period, less than a century younger than Castra Regis. The windows of the study were barred and locked, and heavy dark curtains closed them in. When this was done not a gleam of light from the tower could be seen from outside.

When they were alone, Sir Nathaniel explained that he had taken his old friend, Mr. Salton, into full confidence, and that in future all would work together.

“It together is important for you to be extremely careful. In spite of the fact that our marriage was kept secret, as also your temporary absence, both are known.”

“How? To whom?”

“How, I know not; but I am beginning to have an idea.”

“To her?” asked Adam, in momentary consternation.

Sir Nathaniel shivered perceptibly.

“The White Worm—yes!”

Adam noticed that from now on, his friend never spoke of Lady Arabella otherwise, except when he wished to divert the suspicion of others.

Sir Nathaniel switched off the electric light, and when the room was pitch dark, he came to Adam, took him by the hand, and led him to a seat set in the southern window. Then he softly drew back a piece of the curtain and motioned his companion to look out.

Adam did so, and immediately shrank back as though his eyes had opened on pressing danger. His companion set his mind at rest by saying in a low voice:

“It is all right; you may speak, but speak low. There is no danger here—at present!”

Adam leaned forward, taking care, however, not to press his face against the glass. What he saw would not under ordinary circumstances have caused concern to anybody. With his special knowledge, it was appalling—though the night was now so dark that in reality there was little to be seen.

On the western side of the tower stood a grove of old trees, of forest dimensions. They were not grouped closely, but stood a little apart from each other, producing the effect of a row widely planted. Over the tops of them was seen a green light, something like the danger signal at a railway-crossing. It seemed at first quite still; but presently, when Adam’s eye became accustomed to it, he could see that it moved as if trembling. This at once recalled to Adam’s mind the light quivering above the well-hole in the darkness of that inner room at Diana’s Grove, Oolanga’s awful shriek, and the hideous black face, now grown grey with terror, disappearing into the impenetrable gloom of the mysterious orifice. Instinctively he laid his hand on his revolver, and stood up ready to protect his wife. Then, seeing that nothing happened, and that the light and all outside the tower remained the same, he softly pulled the curtain over the window.

“I have done my best for you, Mr. Darnay; and my best is as good as another man’s, I believe.”

It clearly being incumbent on some one to say, “Much better,” Mr. Lorry said it; perhaps not quite disinterestedly, but with the interested object of squeezing himself back again.

“You think so?” said Mr. Stryver. “Well! you have been present all day, and you ought to know. You are a man of business, too.”

“And as such,” quoth Mr. Lorry, whom the counsel learned in the law had now shouldered back into the group, just as he had previously shouldered him out of it—“as such I will appeal to Doctor Manette, to break up this conference and order us all to our homes. Miss Lucie looks ill, Mr. Darnay has had a terrible day, we are worn out.”

“Speak for yourself, Mr. Lorry,” said Stryver; “I have a night’s work to do yet. Speak for yourself.”

“I speak for myself,” answered Mr. Lorry, “and for Mr. Darnay, and for Miss Lucie, and—Miss Lucie, do you not think I may speak for us all?” He asked her the question pointedly, and with a glance at her father.

His face had become frozen, as it were, in a very curious look at Darnay: an intent look, deepening into a frown of dislike and distrust, not even unmixed with fear. With this strange expression on him his thoughts had wandered away.

“My father,” said Lucie, softly laying her hand on his.

He slowly shook the shadow off, and turned to her.

“Shall we go home, my father?”

With a long breath, he answered “Yes.”

The friends of the acquitted prisoner had dispersed, under the impression—which he himself had originated—that he would not be released that night. The lights were nearly all extinguished in the passages, the iron gates were being closed with a jar and a rattle, and the dismal place was deserted until to–morrow morning’s interest of gallows, pillory, whipping–post, and branding–iron, should repeople it. Walking between her father and Mr. Darnay, Lucie Manette passed into the open air. A hackney–coach was called, and the father and daughter departed in it.

Mr. Stryver had left them in the passages, to shoulder his way back to the robing–room. Another person, who had not joined the group, or interchanged a word with any one of them, but who had been leaning against the wall where its shadow was darkest, had silently strolled out after the rest, and had looked on until the coach drove away. He now stepped up to where Mr. Lorry and Mr. Darnay stood upon the pavement.

“So, Mr. Lorry! Men of business may speak to Mr. Darnay now?”

Nobody had made any acknowledgment of Mr. Carton’s part in the day’s proceedings; nobody had known of it. He was unrobed, and was none the better for it in appearance.

“If you knew what a conflict goes on in the business mind, when the business mind is divided between good–natured impulse and business appearances, you would be amused, Mr. Darnay.”
