The Red Track by Gustave Aimard

It was very late when the conspirators separated, and when the last groups of officers left the rancho, the sound of the Indian horses and mules proceeding to market was audible on the paved highway. Although the darkness was still thick, the stars were beginning to die out in the heavens, the cold was becoming sharper -- in a word, all foretold that day would soon break.

The two travellers had seated themselves again at a corner of the table, opposite one another, and were dumb and motionless as statues. The host walked about the room with a busy air, apparently arranging and clearing up, but very anxious in reality, and desirous, in his heart, to be rid as soon as possible of these two singular customers, whose silence and sobriety inspired him with but slight confidence.
