The next moment they had passed me, and with an effort I had jerked myself back into something like my usual self-possession. Later on the same day, when I had happened to run across the purser, I had made some enquiries concerning the new arrivals. Except for supplying me with their names, however, he had been unable to give me any information, beyond the fact that they had booked through for the full voyage to London, and that they had taken the two best cabins still available. It was from Ross that I subsequently gleaned the few further particulars I knew about them. His medical services had been called in the first evening, and he had been in fairly regular attendance throughout the whole voyage from Manaos to Oporto. From one or two remarks he let drop I gathered that de Roda was suffering from some form of heart trouble, and that although this might, and probably would, get better for a time, any permanent recovery was out of the question. The girl, it appeared, was his patient's niece, and, unlike her uncle, who was an obvious South American through and through, she herself was half English, and spoke the language as fluently and readily as she did Spanish or Portuguese. Ross declared that she was as charming to talk to as she was beautiful to look at, but this was a statement that so far I had no opportunity of putting to a practical test. Throughout the entire voyage both uncle and niece had kept as strictly to themselves as any two people could possibly do on an ocean-going steamer. For the first day or so de Roda's state of health had rendered it advisable that all his meals should be served in his cabin, and it was not until we were half way across that either of them had appeared in the saloon. Even then they had made arrangements with the steward that they should have a private table, and so far as I knew they were only on the barest speaking terms with any of the other passengers. Very occasionally they would stroll round the deck in each other's company, de Roda invariably holding his niece's arm and staring out in front of him with a sombre look that was distinctly discouraging to any casual advances. Now and then in the afternoons Miss de Roda would establish herself in a quiet corner with a book and a deck chair, but the few more intrusive spirits who had attempted to take advantage of this fact did not seem to have met with any startling success.
