Stronghand by Gustave Aimard

Now that we have given the reader all necessary information about the events accomplished at the Hacienda del Toro, we will resume our narrative at the point where we were compelled to leave it -- that is to say, we will return to the village of the Papazos, and be present at the conversation between Thunderbolt and Stronghand in the Pyramid. The two men, walking side by side, went up to the top of the Pyramid. They traversed the bridge of lianas thrown over the Quebrada at a great height, and entered the Pyramid on the right. They descended to the first floor -- the Indians they met bowing respectfully to them -- and stopped before a securely fastened door. On reaching it, Thunderbolt gave it two slight taps; an inner bolt was drawn, the door opened, and they went in. They had scarce crossed the threshold ere the young Indian who had opened the door closed it again after them.

A strange change had taken place in the two men; the Indian stoicism they had hitherto affected made way for manners that revealed men used to frequent the highest society of cities.
