I was astonished to hear him, but his last words were a mystery to me.

“There is no one in Buenos Ayres to protect her,” I said; “I only will be there as I am here to shield her, and if, as you think, she has an enemy, he must reckon with me—one who, like that Calixto you speak of, has a hand quick to strike.”

“There spoke the heart of a Blanco!” he exclaimed, clutching my arm, and then, the boat giving a lurch at that moment, almost dragging me down in his efforts to steady himself. After another sip of rum he went on: “But who are you, young sir, if that is not an impertinent question? Do you possess money, influence, powerful friends, that you take upon yourself the care of this woman? Is it in your power to baffle and crush her enemy or enemies, to protect not only her person, but her property, which, in her absence, will become the prey of robbers?”

“And who are you, old man?” I returned, unable to give a satisfactory answer to one of his searching questions, “and why do you ask me these things? And who is this powerful person you speak of in Buenos Ayres with some of her blood in his veins, but of whose existence she is ignorant?”

He shook his head silently, then deliberately proceeded to take out and light a cigarette. He smoked with a placid enjoyment which made me think that his refusal of my cigar and his bitter complaints about the effects of the ship's tossing on him had merely been to get the bottle of rum out of me. He was evidently a veteran in more senses than one, and now, finding that I would tell him no more secrets, he refused to answer any questions. Fearing that I had imprudently told him too much already, I finally left him and retired to my bunk.

Next morning we arrived at Buenos Ayres, and cast anchor about two miles from shore, for that was as near the land as we could get. Presently we were boarded by a Custom House officer, and for some time longer I was engaged in getting out our luggage and in bargaining with the captain to put us on shore. When I had completed these arrangements I was very much surprised to see the cunning old soldier I had talked with the evening before sitting in the Custom House boat, which was just putting off from the side. Demetria had been looking on when the old fellow had left the ship, and she now came to me looking very excited.

“Richard,” she said, “did you notice that man who was a passenger with us and who has just gone off in the boat? It is Santa Coloma.”

“Oh, absurd!” I exclaimed. “I talked with that old man last night for an hour—an old grey-bearded gaucho, and no more like Santa Coloma than that sailor.”

“I know I am right,” she returned. “The General has visited my father at the estancia and I know him well. He is disguised now and has made himself look like a peasant, but when he went over the side into the boat he looked full into my face; I knew him and started, then he smiled, for he saw that I had recognised him.”

The very fact that this common-looking old man had gone on shore in the Custom House boat proved that he was a person of consequence in disguise, and I could not doubt that Demetria was right. I felt excessively annoyed at myself for having failed to penetrate his disguise; for something of the old Marcos Marcó style of speaking might very well have revealed his identity if I had only had my wits about me. I was also very much concerned on Demetria's account, for it seemed that I had missed finding out something for her which would have been to her advantage to know. I was ashamed to tell her of that conversation about a relation in Buenos Ayres, but secretly determined to try and find Santa Coloma to get him to tell me what he knew.
