These men had not entirely lost all ideas of civilization, and under proper garments their hearts would beat again.

D'Artagnan, not to create any jealousy with the others, made the rest go forward.

He kept his two selected ones, clothed them from his own wardrobe, and set out with them.
It was to these two, whom he seemed to honor with an absolute confidence, that D'Artagnan imparted a false secret, destined to secure the success of the expedition.

He confessed to them that the object was not to learn to what extent French merchants were injured by English smuggling, but to learn how far French smuggling could annoy English trade.

These men appeared convinced; they were effectively so.
D'Artagnan was quite sure that at the first debauch, when thoroughly drunk, one of the two would divulge the secret to the whole band.
