"That is true; pardon me this interruption," said the captain; "you said, then, that you offered to set us at liberty, &c., &c.—on condition—"

"On condition," replied Don Zeno, "that first you will give me your word of honour as gentlemen and soldiers, that whatever happens during all the time that we remain together, you will never utter my name, and that with regard to me you will be inviolably secret."

"At present I do not see anything which prevents us taking this engagement. Then, Señor, for that is not all, I imagine—"

"Just so, that is not all. I wish to go in your company to the camp of Casa-Frama, to treat with Don Pablo Pincheyra on an affair which concerns myself. I will take the name and the costume of a Portuguese officer. You will not betray me, and, moreover, you will aid me in terminating the affair in question; I know that you possess sufficient influence over Don Pablo to enable me to succeed."

"Do you refuse to instruct us as to this affair?" asked the Count.

"By no means. This susceptibility is too honourable for me not to accede to your request. It concerns two Portuguese ladies, the Marchioness de Castelmelhor and her daughter, whom the Pincheyras have seized against the right of nations, and whom I wish to deliver."

"Is that all?"

"Yes, caballero; see if your honour will permit you to accept these conditions?"

"Señor Don Zeno Cabral," answered the Count, "the history which you are pleased to relate to us is very well imagined, although we doubt much the reality of your devotion to these ladies. As they are almost unknown to us, and as you have told us this affair entirely concerns yourself, we do not acknowledge the right to inquire into it; consequently my companions and I accept your conditions, which, let us state, are really very easy. We give you our word of honour to fulfil exactly the engagement that we take with regard to you, without we are otherwise compelled by force."

"We give you our word of honour, as well as our noble friend, Count de Mendoza," said the captain and the colonel together.
