A rogue does not laugh in the same way that an honest man does; a hypocrite does not shed the tears of a man of good faith.

Context

“In fact, in addition to that yellow, sickly paleness which indicates the insinuation of the bile in the blood, and which might, besides, be accidental, d’Artagnan remarked something perfidiously significant in the play of the wrinkled features of his countenance. A rogue does not laugh in the same way that an honest man does; a hypocrite does not shed the tears of a man of good faith. All falsehood is a mask; and however well made the mask may be, with a little attention we may always succeed in distinguishing it from the true face. It appeared, then, to d’Artagnan that M. Bonacieux wore a mask, and likewise that that mask was most disagreeable to look upon.” source
