“To-morrow morning I leave you, and there will be no opportunity of speaking,” I said. “Don Hilario will be here watching you, and, though he is so much in the house, I cannot believe that you trust him.” She started at the name of Don Hilario, and cried a little in silence; then suddenly she rose and gave me her hand to bid good night. “You shall know everything to-morrow, Richard,” she said. “Then you will know how much I trust you and how little I trust him. I cannot speak myself, but I can trust Santos, who knows everything, and he shall tell you all.” There was a sad, wistful look in her eyes when we parted that haunted me for hours afterwards. Coming into the kitchen, I disturbed Ramona and Santos deep in a whispered consultation. They started up, looking somewhat confused; then, when I had lit a cigar and turned to go out, they got up and went back to their mistress. While I smoked I pondered over the strange evening I had passed, wondering very much what Demetria's secret trouble could be. “The mystery of the green butterfly,” I called it; but it was really all too sad even for a mental joke, though a little timely laughter is often the best weapon to meet trouble with, sometimes having an effect like that of a gay sunshade suddenly opened in the face of an angry bull. Unable to solve the riddle, I retired to my room to sleep my last sleep under Peralta's dreary roof. CHAPTER XXV About eight o'clock next morning I bade the Peraltas goodbye, and set out on my long-delayed journey, still mounted on that dishonestly acquired steed that had served me so well, for I had declined the good Hilario's offer of a horse. Though all my toils, wanderings, and many services to the cause of liberty (or whatever people fight for in the Banda) had not earned me one copper coin, it was some comfort to think that Candelaria's never-to-be-forgotten generosity had saved me from being penniless; I was, in fact, returning to Paquíta well dressed, on a splendid horse, and with dollars enough in my pocket to take us comfortably out of the country. Santos rode out with me, ostensibly to put me on the right road to Montevideo; only I knew, of course, that he was the bearer of an important communication from Demetria. When we had ridden about half a league without any approach to the subject on his part, in spite of sundry hints I threw out, I asked him plainly if he had a message for me. After pondering over the question for as long a time as would be necessary to work out a rather difficult mathematical problem, he answered that he had. “Then,” said I, “let me hear it.” He grinned. “Do you think,” he said, “that it is a thing to be spoken in half a dozen words? I have not come all this distance merely to say that the moon came in dry, or that yesterday, being Friday, Doña Demetria tasted no meat. It is a long story, señor.”
