Watching, Hugh saw the chauffeur jump from his seat, and he plainly saluted the other most respectfully.

Hugh paid particular attention to that part of the affair, because any pedestrian might have stopped to pass a few words with a car driver, or ask a question; but the pilot would hardly have made that positive sign unless there was a reason for his action.
Now they seemed to be talking earnestly.

Brother Lu made gestures, and Hugh took notice of the fact that he seemed to be speaking with authority, because the chauffeur constantly nodded his bead, as if to say that he understood.
Then the man took something from under the front seat cushion of the car and handed it to Brother Lu.

Hugh could not be positive, but he rather fancied it was a packet of folded papers.
Plainly, then, there was a conspiracy afloat.

Brother Lu was other than he pretended to be, and he was undoubtedly hatching up some sort of plot that had connections with the peace of mind of the two simple Hosmers who had taken him in on the strength of his claim to blood relationship.
Hugh was quivering more than ever now, and his breath came in gasps as he continued to keep his eyes glued on the two figures not so far away.
