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 all would work together.

“It 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.

“Carton,” said his friend, squaring himself at him with a bullying air, as if the fire–grate had been the furnace in which sustained endeavour was forged, and the one delicate thing to be done for the old Sydney Carton of old Shrewsbury School was to shoulder him into it, “your way is, and always was, a lame way. You summon no energy and purpose. Look at me.”

“Oh, botheration!” returned Sydney, with a lighter and more good–humoured laugh, “don’t YOU be moral!”

“How have I done what I have done?” said Stryver; “how do I do what I do?”

“Partly through paying me to help you, I suppose. But it’s not worth your while to apostrophise me, or the air, about it; what you want to do, you do. You were always in the front rank, and I was always behind.”

“I had to get into the front rank; I was not born there, was I?”

“I was not present at the ceremony; but my opinion is you were,” said Carton. At this, he laughed again, and they both laughed.

“Before Shrewsbury, and at Shrewsbury, and ever since Shrewsbury,” pursued Carton, “you have fallen into your rank, and I have fallen into mine. Even when we were fellow–students in the Student–Quarter of Paris, picking up French, and French law, and other French crumbs that we didn’t get much good of, you were always somewhere, and I was always nowhere.”

“And whose fault was that?”

“Upon my soul, I am not sure that it was not yours. You were always driving and riving and shouldering and passing, to that restless degree that I had no chance for my life but in rust and repose. It’s a gloomy thing, however, to talk about one’s own past, with the day breaking. Turn me in some other direction before I go.”

“Well then! Pledge me to the pretty witness,” said Stryver, holding up his glass. “Are you turned in a pleasant direction?”

Apparently not, for he became gloomy again.

“Pretty witness,” he muttered, looking down into his glass. “I have had enough of witnesses to–day and to–night; who’s your pretty witness?”

“The picturesque doctor’s daughter, Miss Manette.”

“SHE pretty?”

“Is she not?”

“No.”

“Why, man alive, she was the admiration of the whole Court!”

“Rot the admiration of the whole Court! Who made the Old Bailey a judge of beauty? She was a golden–haired doll!”

“Do you know, Sydney,” said Mr. Stryver, looking at him with sharp eyes, and slowly drawing a hand across his florid face: “do you know, I rather thought, at the time, that you sympathised with the golden–haired doll, and were quick to see what happened to the golden–haired doll?”

“Quick to see what happened! If a girl, doll or no doll, swoons within a yard or two of a man’s nose, he can see it without a perspective–glass. I pledge you, but I deny the beauty. And now I’ll have no more drink; I’ll get to bed.”
