It was a long, grieving sound, like a sigh—almost like a sob. It attracted Mr. Lorry’s eyes to Carton’s face, which was turned to the fire. A light, or a shade (the old gentleman could not have said which), passed from it as swiftly as a change will sweep over a hill–side on a wild bright day, and he lifted his foot to put back one of the little flaming logs, which was tumbling forward. He wore the white riding–coat and top–boots, then in vogue, and the light of the fire touching their light surfaces made him look very pale, with his long brown hair, all untrimmed, hanging loose about him. His indifference to fire was sufficiently remarkable to elicit a word of remonstrance from Mr. Lorry; his boot was still upon the hot embers of the flaming log, when it had broken under the weight of his foot.

“I forgot it,” he said.

Mr. Lorry’s eyes were again attracted to his face. Taking note of the wasted air which clouded the naturally handsome features, and having the expression of prisoners’ faces fresh in his mind, he was strongly reminded of that expression.

“And your duties here have drawn to an end, sir?” said Carton, turning to him.

“Yes. As I was telling you last night when Lucie came in so unexpectedly, I have at length done all that I can do here. I hoped to have left them in perfect safety, and then to to have quitted Paris. I have my Leave to Pass. I was ready to go.”

They were both silent.

“Yours is a long life to look back upon, sir?” said Carton, wistfully.

“I am in my seventy–eighth year.”

“You have been useful all your life; steadily and constantly occupied; trusted, respected, and looked up to?”

“I have been a man of business, ever since I have been a man. indeed, I may say that I was a man of business when a boy.”

“See what a place you fill at seventy–eight. How many people will miss you when you leave it empty!”

“A solitary old bachelor,” answered Mr. Lorry, shaking his head. “There is nobody to weep for me.”

“How can you say that? Wouldn’t She weep for you? Wouldn’t her child?”

“Yes, yes, thank God. I didn’t quite mean what I said.”

“It IS a thing to thank God for; is it not?”

“Surely, surely.”

“If you could say, with truth, to your own solitary heart, to–night, ‘I have secured to myself the love and attachment, the gratitude or respect, of no human creature; I have won myself a tender place in no regard; I have done nothing good or serviceable to be remembered by!’ your seventy–eight years would be seventy–eight heavy curses; would they not?”

“You say truly, Mr. Carton; I think they would be.”

Sydney turned his eyes again upon the fire, and, after a silence of a few moments, said:

“I should like to ask you:—Does your childhood seem far off? Do the days when you sat at your mother’s knee, seem days of very long ago?”

At last she entered on the grounds of the Castle, at a spot from which the windows of the turret were dimly visible, without having seen again any sign of Lady Arabella.

Meanwhile, during most of the time that Mimi Salton had been moving warily along in the gloom, she was in reality being followed by Lady Arabella, who had caught sight of her leaving the house and had never again lost touch with her. It was a case of the hunter being hunted. For a time Mimi’s many turnings, with the natural obstacles that were perpetually intervening, caused Lady Arabella some trouble; but when she was close to Castra Regis, there was no more possibility of concealment, and the strange double following went swiftly on.

When she saw Mimi close to the hall door of Castra Regis and ascending the steps, she followed. When Mimi entered the dark hall and felt her way up the staircase, still, as she believed, following Lady Arabella, the latter kept on her way. When they reached the lobby of the turret-rooms, Mimi believed that the object of her search was ahead of her.

Edgar Caswall sat in the gloom of the great room, occasionally stirred to curiosity when the drifting clouds allowed a little light to fall from the storm-swept sky. But nothing really interested him now. Since he had heard of Lilla’s death, the gloom of his remorse, emphasised by Mimi’s upbraiding, had made more hopeless his cruel, selfish, saturnine nature. He heard no sound, for his normal faculties seemed benumbed.

Mimi, when she came to the door, which stood ajar, gave a light tap. So light was it that it did not reach Caswall’s ears. Then, taking her courage in both hands, she boldly pushed the door and entered. As she did so, her heart sank, for now she was face to face with a difficulty which had not, in her state of mental perturbation, occurred to her.

The storm which was coming was already making itself manifest, not only in the wide scope of nature, but in the hearts and natures of human beings. Electrical disturbance in the sky and the air is reproduced in animals of all kinds, and particularly in the highest type of them all—the most receptive—the most electrical. So it was with Edgar Caswall, despite his selfish nature and coldness of blood. So it was with Mimi Salton, despite her unselfish, unchanging devotion for those she loved. So it was even with Lady Arabella, who, under the instincts of a primeval serpent, carried the ever-varying wishes and customs of womanhood, which is always old—and always new.

Edgar, after he had turned his eyes on Mimi, resumed his apathetic position and sullen silence. Mimi quietly took a seat a little way apart, whence she could look on the progress of the coming storm and study its appearance throughout the whole visible circle of the neighbourhood. She was in brighter and better spirits than she had been for many days past. Lady Arabella tried to efface herself behind the now open door.

Without, the clouds grew thicker and blacker as the storm-centre came closer. As yet the forces, from whose linking the lightning springs, were held apart, and the silence of nature proclaimed the calm before the storm. Caswall felt the effect of the gathering electric force. A sort of wild exultation grew upon him, such as he had sometimes felt just before the breaking of a tropical storm. As he became conscious of this, he raised his head and caught sight of Mimi. He was in the grip of an emotion greater than himself; in the mood in which he was he felt the need upon him of doing some desperate deed. He was now absolutely reckless, and as Mimi was associated with him in the memory which drove him on, he wished that she too should be engaged in this enterprise. He had no knowledge of the proximity of Lady Arabella, and thought that he was far removed from all he knew and whose interests he shared—alone with the wild elements, which were being lashed to fury, and with the woman who had struggled with him and vanquished him, and on whom he would shower the full measure of his hate.
