ARNOLD’S mind was far from easy when he was left by himself again in the smoking-room.

After wasting some time in vainly trying to guess at the source from which Lady Lundie had derived her information, he put on his hat, and took the direction which led to Blanche’s favorite walk at Ham Farm. Without absolutely distrusting her ladyship’s discretion, the idea had occurred to him that he would do well to join his wife and her step-mother. By making a third at the interview between them, he might prevent the conversation from assuming a perilously confidential turn.

The search for the ladies proved useless. They had not taken the direction in which he supposed them to have gone.

He returned to the smoking-room, and composed himself to wait for events as patiently as he might. In this passive position—with his thoughts still running on Lady Lundie—his memory reverted to a brief conversation between Sir Patrick and himself, occasioned, on the previous day, by her ladyship’s announcement of her proposed visit to Ham Farm. Sir Patrick had at once expressed his conviction that his sister-in-law’s journey south had some acknowledged purpose at the bottom of it.

“I am not at all sure, Arnold” (he had said), “that I have done wisely in leaving her letter unanswered. And I am strongly disposed to think that the safest course will be to take her into the secret when she comes to-morrow. We can’t help the position in which we are placed. It was impossible (without admitting your wife to our confidence) to prevent Blanche from writing that unlucky letter to her—and, even if we had prevented it, she must have heard in other ways of your return to England. I don’t doubt my own discretion, so far; and I don’t doubt the convenience of keeping her in the dark, as a means of keeping her from meddling in this business of yours, until I have had time to set it right. But she may, by some unlucky accident, discover the truth for herself—and, in that case, I strongly distrust the influence which she might attempt to exercise on Blanche’s mind.”

Those were the words—and what had happened on the day after they had been spoken? Lady Lundie had discovered the truth; and she was, at that moment, alone somewhere with Blanche. Arnold took up his hat once more, and set forth on the search for the ladies in another direction.

The second expedition was as fruitless as the first. Nothing was to be seen, and nothing was to be heard, of Lady Lundie and Blanche.

Arnold’s watch told him that it was not far from the time when Sir Patrick might be expected to return. In all probability, while he had been looking for them, the ladies had gone back by some other way to the house. He entered the rooms on the ground-floor, one after another. They were all empty. He went up stairs, and knocked at the door of Blanche’s room. There was no answer. He opened the door and looked in. The room was empty, like the rooms down stairs. But, close to the entrance, there was a trifling circumstance to attract notice, in the shape of a note lying on the carpet. He picked it up, and saw that it was addressed to him in the handwriting of his wife.

He opened it. The note began, without the usual form of address, in these words:

“I know the abominable secret that you and my uncle have hidden from me. I know your infamy, and her infamy, and the position in which, thanks to you and to her, I now stand. Reproaches would be wasted words, addressed to such a man as you are. I write these lines to tell you that I have placed myself under my step-mother’s protection in London. It is useless to attempt to follow me. Others will find out whether the ceremony of marriage which you went through with me is binding on you or not. For myself, I know enough already. I have gone, never to come back, and never to let you see me again.—Blanche.”

Hurrying headlong down the stairs with but one clear idea in his mind—the idea of instantly following his wife—Arnold encountered Sir Patrick, standing by a table in the hall, on which cards and notes left by visitors were usually placed, with an open letter in his hand. Seeing in an instant what had happened, he threw one of his arms round Arnold, and stopped him at the house-door.

“You are a man,” he said, firmly. “Bear it like a man.”

Arnold’s head fell on the shoulder of his kind old friend. He burst into tears.

Sir Patrick let the irrepressible outbreak of grief have its way. In those first moments, silence was mercy. He said nothing. The letter which he had been reading (from Lady Lundie, it is needless to say), dropped unheeded at his feet.

Arnold lifted his head, and dashed away the tears.

“I am ashamed of myself,” he said. “Let me go.”

“Wrong, my poor fellow—doubly wrong!” returned Sir Patrick. “There is no shame in shedding such tears as those. And there is nothing to be done by leaving me.”

“I must and will see her!”

“Read that,” said Sir Patrick, pointing to the letter on the floor. “See your wife? Your wife is with the woman who has written those lines. Read them.”

Arnold read them.

“DEAR SIR PATRICK,—If you had honored me with your confidence, I should have been happy to consult you before I interfered to rescue Blanche from the position in which Mr. Brinkworth has placed her. As it is, your late brother’s child is under my protection at my house in London. If you attempt to exercise your authority, it must be by main force—I will submit to nothing less. If Mr. Brinkworth attempts to exercise his authority, he shall establish his right to do so (if he can) in a police-court.

“Very truly yours, JULIA LUNDIE.”

Arnold’s resolution was not to be shaken even by this. “What do I care,” he burst out, hotly, “whether I am dragged through the streets by the police or not! I will see my wife. I will clear myself of the horrible suspicion she has about me. You have shown me your letter. Look at mine!”

Sir Patrick’s clear sense saw the wild words that Blanche had written in their true light.

“Do you hold your wife responsible for that letter?” he asked. “I see her step-mother in every line of it. You descend to something unworthy of you, if you seriously defend yourself against this! You can’t see it? You persist in holding to your own view? Write, then. You can’t get to her—your letter may. No! When you leave this house, you leave it with me. I have conceded something on my side, in allowing you to write. I insist on your conceding something, on your side, in return. Come into the library! I answer for setting things right between you and Blanche, if you will place your interests in my hands. Do you trust me or not?”

Arnold yielded. They went into the library together. Sir Patrick pointed to the writing-table. “Relieve your mind there,” he said. “And let me find you a reasonable man again when I come back.”

When he returned to the library the letter was written; and Arnold’s mind was so far relieved—for the time at least.

“I shall take your letter to Blanche myself,” said Sir Patrick, “by the train that leaves for London in half an hour’s time.”

“You will let me go with you?”

“Not to-day. I shall be back this evening to dinner. You shall hear all that has happened; and you shall accompany me to London to-morrow—if I find it necessary to make any lengthened stay there. Between this and then, after the shock that you have suffered, you will do well to be quiet here. Be satisfied with my assurance that Blanche shall have your letter. I will force my authority on her step-mother to that extent (if her step-mother resists) without scruple. The respect in which I hold the sex only lasts as long as the sex deserves it—and does not extend to Lady Lundie. There is no advantage that a man can take of a woman which I am not fully prepared to take of my sister-in-law.”

With that characteristic farewell, he shook hands with Arnold, and departed for the station.

At seven o’clock the dinner was on the table. At seven o’clock Sir Patrick came down stairs to eat it, as perfectly dressed as usual, and as composed as if nothing had happened.

“She has got your letter,” he whispered, as he took Arnold’s arm, and led him into the dining-room.

“Did she say any thing?”

“Not a word.”

“How did she look?”

“As she ought to look—sorry for what she has done.”

The dinner began. As a matter of necessity, the subject of Sir Patrick’s expedition was dropped while the servants were in the room—to be regularly taken up again by Arnold in the intervals between the courses. He began when the soup was taken away.

“I confess I had hoped to see Blanche come back with you!” he said, sadly enough.

“In other words,” returned Sir Patrick, “you forgot the native obstinacy of the sex. Blanche is beginning to feel that she has been wrong. What is the necessary consequence? She naturally persists in being wrong. Let her alone, and leave your letter to have its effect. The serious difficulties in our way don’t rest with Blanche. Content yourself with knowing that.”

The fish came in, and Arnold was silenced—until his next opportunity came with the next interval in the course of the dinner.

“What are the difficulties?” he asked

“The difficulties are my difficulties and yours,” answered Sir Patrick. “My difficulty is, that I can’t assert my authority, as guardian, if I assume my ............
