While he was walking up and down the library, unable to settle to any examination of those calm business papers in which no agitation was, a letter was brought to him. It bore the stamp of a post-town at a short distance, and he turned it over listlessly enough, until it occurred to him that the writing was that of his sister-in-law. Madam wrote as many women write; there was nothing remarkable about her hand. John Trevanion opened the letter with excitement. It was as follows:

“Dear Brother John,—You may not wish me to call you so now, but I have always felt towards you so, and it still seems a link to those I have left behind to have one relationship which I may claim. There seems no reason why I should not write to you, or why I should conceal from you where I am. You will not seek to bring me back; I am safe enough in your hands. I am going out of England, but if you want to communicate with me on any subject, the bankers will always know where I am. It is, as I said, an additional humiliation in my great distress that I must take the provision my husband has made, and cannot fling it back to you indignantly as a younger woman might. I am old enough to know, and bitterly acknowledge, that I cannot hope to maintain myself; and I have others dependent on me. This necessity will always make it easy enough to find me, but I do not fear that you will wish to seek me out or bring me back.

“I desire you to know that I understand my husband’s will better than any one else, and perhaps, knowing his nature, blame him less than you will be disposed to do. When he married me I was very forlorn and miserable. I had a story, which is the saddest thing that can be said of a woman. He was generous to me then in every particular but one, but that one was very important. I had to make a sacrifice, an unjustifiable sacrifice, and a promise which was unnatural. Herein lies my fault. I have not kept that promise; I could not; it was more than flesh and blood was capable of; and I deceived him. I was always aware that if he discovered it he might, and probably would, take summary vengeance. Now he has discovered it, and he has done without ruth what he promised me to do if I broke my word to him. I deserve it, you see, though not in the way the vulgar will suppose. To them I cannot explain, and circumstances, alas, make it impossible for me to be explicit even with you. But perhaps, even in writing so much, you may be delivered from some suspicions of me which, if I read you right, you will be glad to find are not justified.

“Farewell, dear John; if we ever should meet in this world—if I should ever be cleared— I cannot tell—most likely not—my children will grow up without knowing me; but I dare not think on that subject, much less say anything. God bless them! Be as much a father to them as you can, and let my Rosalind have the letter I enclose; it will do her no harm: anyhow, she would not believe harm of me, even though she saw what looked like harm. Pity me a little, John. I have taken my doom quietly because I have no hope—neither in what I leave nor in what I go to is there any hope.

Grace Trevanion.”

This letter forced tears, such as a man is very slow to shed, to John Trevanion’s eyes; but there was in reality no explanation in it, no light upon the family catastrophe, or the confusion of misery and perplexity she had left behind.

CHAPTER XXIV.

“Have you ever noticed in your walks, doctor, a young fellow?—you couldn’t but remark him—a sort of primo tenore, big eyed, pale faced—”

“All pulmonary,” said Dr. Beaton. “I know the man you mean. He has been hanging about for a month, more or less, with no visible object. To tell the truth—”

John Trevanion raised his hand instinctively. “I find,” he said, interrupting with a hurried precaution, “that he has been in hiding for some offence, and men have come after him here because of an envelope with the Highcourt stamp—”
