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 and that in future 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.

“Miss Manette, have you seen the prisoner before?”

“Yes, sir.”

“Where?”

“On board of the packet–ship just now referred to, sir, and on the same occasion.”

“You are the young lady just now referred to?”

“O! most unhappily, I am!”

The plaintive tone of her compassion merged into the less musical voice of the Judge, as he said something fiercely: “Answer the questions put to you, and make no remark upon them.”

“Miss Manette, had you any conversation with the prisoner on that passage across the Channel?”

“Yes, sir.”

“Recall it.”

In the midst of a profound stillness, she faintly began: “When the gentleman came on board—”

“Do you mean the prisoner?” inquired the Judge, knitting his brows.

“Yes, my Lord.”

“Then say the prisoner.”

“When the prisoner came on board, he noticed that my father,” turning her eyes lovingly to him as he stood beside her, “was much fatigued and in a very weak state of health. My father was so reduced that I was afraid to take him out of the air, and I had made a bed for him on the deck near the cabin steps, and I sat on the deck at his side to take care of him. There were no other passengers that night, but we four. The prisoner was so good as to beg permission to advise me how I could shelter my father from the wind and weather, better than I had done. I had not known how to do it well, not understanding how the wind would set when we were out of the harbour. He did it for me. He expressed great gentleness and kindness for my father’s state, and I am sure he felt it. That was the manner of our beginning to speak together.”

“Let me interrupt you for a moment. Had he come on board alone?”

“No.”

“How many were with him?”

“Two French gentlemen.”

“Had they conferred together?”

“They had conferred together until the last moment, when it was necessary for the French gentlemen to be landed in their boat.”

“Had any papers been handed about among them, similar to these lists?”

“Some papers had been handed about among them, but I don’t know what papers.”

“Like these in shape and size?”

“Possibly, but indeed I don’t know, although they stood whispering very near to me: because they stood at the top of the cabin steps to have the light of the lamp that was hanging there; it was a dull lamp, and they spoke very low, and I did not hear what they said, and saw only that they looked at papers.”

“Now, to the prisoner’s conversation, Miss Manette.”

“The prisoner was as open in his confidence with me—which arose out of my helpless situation—as he was kind, and good, and useful to my father. I hope,” bursting into tears, “I may not repay him by doing him harm to–day.”
