"The end of my story I judge now that you anticipate. Though absolutely convinced myself, I had still lack of the one direct link to make a legal chain. I had positively to connect the man Black with the nameless ship, for this I had only done so far by pure circumstance. For many months I have made no gain in this attempt. Last year in Liverpool I sketched in yet another point in my picture. I received tidings of the man in that city, and there I did trade with him in my old disguise; but he was not alone--the crew of ruffians you have known by this time kept company with him in that bold and bestial Bohemianism you will have witnessed with me. I kept vigil there a week, but lost him at the end of that time. When he reappeared in the circles of civilisation it was in Paris, but two days ago, when I asked you to accompany me. You know that I attempted to sail with him on his cruise, and your instinct tells you why. If I could, by being two days afloat in his company, prove beyond doubt that he used his yacht as a pretence; if I could prove that when he left port in her he sailed out to sea, and was picked up by the nameless ship, my chain was forged, my book complete, and I had but to call the Government to the work!
"But I have failed, and the labour I have set myself shall be done by others, but chiefly, Mark Strong, by you. From the valley of the dead whence soon I must look back, if it is to be on a life that has no achievement before God in it, I, who have laid down such a life as mine was in this cause, urge you upon it. You have youth, and money sufficient for the enterprise; you will get money in its pursuit. You have no fear of the black After, which is the end of life; but, after all, it may come to you as it came to me, that there is the finger of the Almighty God pointing to your path of duty. I have lived the life of a common eavesdropper; but believe me that in this work I have felt the call of humanity, and hoped, if I might live to accomplish it, that the Book of the Good should find some place for my name. So may you when my mantle falls upon you. What information I have, you have. The names of my friends in the cities mentioned I have written down for you; they will serve you for the memory of my name; but be assured at the outset that you will never take this man upon the sea. And as for the money which is rightly due to the one who rids humanity of this pest, I say, go to the Admiralty in London, and lay so much of your knowledge before them as shall prevent a robbery of your due; claim a fit reward from them and the steamship companies; and, as your beginning, go now to the Hudson River--I meant to go within a month--and learn there more of the man you seek; or, if the time be ripe, lay hands there upon him. And may the spirit of a dead man breathe success upon you!"
