As I could not secure a carriage to myself in the train by which I returned to town I had to defer a closer examination of the papers I had found until I had gained the seclusion of my own chambers in Buckingham Street.

The first of the documents contained in Green’s cigar-case was a letter, evidently addressed to Mullen. It was dated from “Stavanger, Norway,” and ran as follows:—

“James,—I know all. I have never tried to spy into your affairs, but I have known for a long time that you have been engaged in some secret undertaking which I felt sure was for no good purpose. Your sudden disappearances and equally sudden reappearances and the large sums of money you have had, have always been a source of anxiety to me. That it was some political plot you were engaged in I was certain, for you were not at such pains to disguise your real views before me as you were before others. I remember your wild talk about society having conspired to rob you from before your birth,—of your being denied the right to bear your father’s name, and of your mother’s name being a dishonour to you. That your father was a villain to our mother I know, and it may be that from him you inherit your evil tendencies, and that God may not hold you morally responsible for them. But James, bad as your father must have been, he was, after all, your father, and the language you sometimes used about him has made me, who am used to your violence, shudder and turn sick.

“James, I promised our dead mother on her death-bed that I would try to be to you all that she was. She could do almost as she liked with you—could soften you and turn you from evil as no other person in the world could. There was some strange sympathy between you and her. Perhaps your knowledge of her one and only sin made you tender and chivalrous to her, just as it sometimes—God forgive me!—made me, who am so different from you and her, hard. And perhaps her memory of her one sinning made her gentle and tender to you in your many. I have had children of my own since then, James, and I think something has thawed in my heart that was cold as ice before.

“I remember that in those childish days, when you would come to our mother after some wild and wicked deed, she would take you in her arms and speak softly to you, and that you would become another creature and would seek to undo the evil you had done. But I used to become impatient. I wished that you should be punished, and I remember that my words would turn you to stone again and bring that hard glitter that I so hated into your eyes. Yes, and when I saw her caressing you, whom I would have had flogged, I used to feel—though she was my mother as well as yours—as if I were a stranger in the house, and could not be of the same flesh and blood as you and she.

“That is long ago, James, and we are no longer boy and girl, but man and woman. But my heart tells me that I have not kept my promise to her. She said to me when she was dying, ‘Mary, I am afraid for James. He can be chivalrously generous to those who appeal to his protection; he can be heartlessly cruel to those who oppose his will. You remember how as a boy he fought like a wild cat with two lads twice his size in defence of the homeless cur that crawled to his feet when they were stoning it; and you remember that upon the same day, because his own dog snarled at him, he beat it about the head so mercilessly that we had to kill it. Mary, I am afraid for James; I am the one and only soul in this world—where, young as he is, he feels himself an outcast—who understands him. And everything depends upon his associations. He might be a good man or he might be criminal. Mary, promise me you will not be too hard with him—promise me that you will try to understand him, and to make allowance, and to be gentle.’

“I promised her, James, and I meant to keep my promise, but I know now that I have not done so. I did not grudge you money. I gave you more of what my father left me than I kept. But I did not try to be to you what I promised our mother to be. I know now, though I did not know it then. I have reason to know it now, for my little son Stanley looks up at me with your eyes to reproach me with it. What you once were he now is in looks and in disposition. I fear for him as your mother feared for you; and his mother knows now that the promise I made to your mother I did not keep.

“James, if you have done evil I am greatly to blame. If I had kept my promise, if I had tried to take our dead mother’s place in your life, if I had aimed at being your companion, and at winning your confidence, if I had sought to keep evil influences away and to set good influences at work, you might never have formed the associations you have formed. That you have done the things they lay to your charge I cannot believe. I have seen the ‘Daily Record,’ and the portrait, and I know only too well, in spite of the disguise, that the James Mullen who is accused of being Captain Shannon is my half-brother James. I will never believe—nothing will make me believe—that it is really true, and that you are responsible for the inhuman crimes which you are said to have committed or to have caused to be committed. That you are associated with men who are capable of any wickedness is, I fear, only too true; men who, by flattering that fatal vanity of yours, which I know so well—that constitutional craving to be thought important and a power, of which I can see traces in the Manifesto which was published after the explosion—have made you their tool, and have persuaded you to accept responsibilities for actions in which you had no hand, I can readily believe. But that you, whom I have known to do such chivalrous actions, you whom I have seen empty your pockets to relieve some beggar whose woe-begone looks had appealed to your pity, could deliberately plan the murder of hundreds of inoffensive people, I cannot and never will believe.

“Until I received your letter I did not know where to write to you, and I feared to send to the old address lest my note should fall into wrong hands. You say that you have got into a scrape, and that I must help you to get out of England, as you cannot trust your associates—which I can well believe. You say, too, that you must get right away to America or Australia, and that I must lend you the steam yacht, as it would not be safe to go by any ordinary passenger steamer, all of which are being watched. You say you would not drag me into such a miserable business if you could help it, but that you dare not risk the chance of attracting the attention in which your chartering yourself a boat big enough to cross to America might result.

“Well I see the force of all this, and I will do what I can to help you, but only on one condition. How heartily my husband and I abhor the acts of those with whom you are associated you must know. Not even to save your life, not even to keep our connection with you from becoming known, not even to save our children from being branded throughout their lives as the relatives of a man who was accused of the blackest murder, would we move hand or foot in any matter which might even in the smallest detail further the infamous scheme in which your associates are engaged.
