"There are people whom a man cannot mean to insult," the stranger continued in a cutting voice. "Remember this, señor padre—I do not wish to have any dealings with you."

"Why so?"

"Because I do not please—that is all. Now, gentlemen, do not trouble yourselves about me, I beg, but continue your conversation: it was most interesting when I arrived. You were speaking, I believe, about an expedition you are preparing: there was a question too, I fancy, when I entered, about a girl your worthy friend, or partner—I do not know which he is—carried off with your assistance.
