Then, quite suddenly, my senses seemed to come back to me. I caught sight of several passengers advancing towards the companion, and, taking out my case, I lighted myself a cigarette, and strolled very slowly in the direction of the stern. At this hour the stretch of deck behind the donkey engine house was absolutely deserted. A better place for a little quiet meditation could scarcely have been found, and, leaning over the railing, I set about the process with as much steadiness as my disturbed faculties would permit. One thing seemed absolutely certain. Whatever Miss de Roda's original views may have been as to the wisdom of continuing her friendship with me, it was her sudden discovery about my uncle which had been wholly responsible for the extraordinary change in her manner. If I had told her that I was the nephew of Judas Iscariot the result could hardly have been more striking. The mere mention of Richard Jannaway's name had been sufficient to fill her with such amazement and horror that she had been quite incapable of making any attempt at hiding her feelings. This fact of itself would have been sufficiently remarkable, but to me its significance was doubly increased by the way she had behaved the previous day during our little discussion with the boatmen. Any girl who could have shown such perfect coolness under the circumstances must be gifted with a spirit and nerve that were not easily shaken. I was, therefore, convinced that it must have taken some very real and urgent sense of danger to upset so completely her usual self-control. Having arrived at this point, I found myself utterly at sea. Beyond the fact that the mystery was in some way or other connected with my uncle I had practically nothing to go upon. If the family recollections of that distinguished gentleman could be trusted, he had probably thrown himself heartily into all kinds of mischief during the course of his South American career, and since the de Rodas came from that part of the world it was quite possible that the name of Richard Jannaway might be connected with some black, unwholesome memory which overshadowed both their lives. Señor de Roda was just the sort of man who suggested a mysterious past. His obvious avoidance of any sort of society, and the brooding depression which always haunted his sallow face, were exactly in keeping with the idea. The more I thought it over the more probable it seemed that at some period in his life he had been mixed up with my disreputable relation, and I began to feel an acute desire for a little genuine information about the tatter's history. The most likely people to be able to gratify this curiosity appeared to be Messrs. Wilmot and Drayton. However secretive their late client may have been, they would at least know more about him than I did, and such facts as they possessed might well be the starting-point for further discoveries.
