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 is important for 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.

“You speak collectedly, and you—ARE collected. That’s good!” (Though his manner was less satisfied than his words.) “A matter of business. Regard it as a matter of business–business that must be done. Now if this doctor’s wife, though a lady of great courage and spirit, had suffered so intensely from this cause before her little child was born—”

“The little child was a daughter, sir.”

“A daughter. A–a–matter of business—don’t be distressed. Miss, if the poor lady had suffered so intensely before her little child was born, that she came to the determination of sparing the poor child the inheritance of any part of the agony she had known the pains of, by rearing her in the belief that her father was dead—No, don’t kneel! In Heaven’s name why should you kneel to me!”

“For the truth. O dear, good, compassionate sir, for the truth!”

“A–a matter of business. You confuse me, and how can I transact business if I am confused? Let us be clear–headed. If you could kindly mention now, for instance, what nine times ninepence are, or how many shillings in twenty guineas, it would be so encouraging. I should be so much more at my ease about your state of mind.”

Without directly answering to this appeal, she sat so still when he had very gently raised her, and the hands that had not ceased to clasp his wrists were so much more steady than they had been, that she communicated some reassurance to Mr. Jarvis Lorry.

“That’s right, that’s right. Courage! Business! You have business before you; useful business. Miss Manette, your mother took this course with you. And when she died—I believe broken–hearted—having never slackened her unavailing search for your father, she left you, at two years old, to grow to be blooming, beautiful, and happy, without the dark cloud upon you of living in uncertainty whether your father soon wore his heart out in prison, or wasted there through many lingering years.”

As he said the words he looked down, with an admiring pity, on the flowing golden hair; as if he pictured to himself that it might have been already tinged with grey.

“You know that your parents had no great possession, and that what they had was secured to your mother and to you. There has been no new discovery, of money, or of any other property; but—”

He felt his wrist held closer, and he stopped. The expression in the forehead, which had so particularly attracted his notice, and which was now immovable, had deepened into one of pain and horror.

“But he has been—been found. He is alive. Greatly changed, it is too probable; almost a wreck, it is possible; though we will hope the best. Still, alive. Your father has been taken to the house of an old servant in Paris, and we are going there: I, to identify him if I can: you, to restore him to life, love, duty, rest, comfort.”

A shiver ran through her frame, and from it through his. She said, in a low, distinct, awe–stricken voice, as if she were saying it in a dream,
