Letitia was eight years old, when a person of genteel address and fashionable appearance, named Duval, was introduced to her mother by her father, with whom he had been intimate when a youth, and between whom a strong friendship had existed from that period. Duval had recently returned from Europe, where he had resided a number of years. He was charmed with the family, and soon became a constant visitor. Having the entire confidence of his old friend and companion, all formality in reference to intercourse was laid aside, and he was heartily welcomed at all hours, and under all circumstances. He formed one in all parties of pleasure, and in the absence of his friend, accompanied his lady on her visits of amusement and pleasure,--a privilege which he sedulously improved whenever opportunity offered. Duval, notwithstanding his personal attractions and high character as a 'gentleman,' belonged to a class of men which has existed more or less in all ages, to disgrace humanity. He professed to be a philosopher, but was in reality a libertine. He lived for his own gratification. It monopolized all his thoughts, and directed all his actions. He belonged to the school of Voltaire, and recognized no feeling of the heart as pure, no tie of duty or affection as sacred. No consideration of suffering, of heart-rending grief, on the part of his victim, were sufficient to intimidate his purpose, or check his career of infamy. Schooled in hypocrisy, dissimulation was his business: and he regarded the whole world as the sphere of his operations,--the whole human family as legitimate subjects for his villainous depravity. That such characters,--so base, so despicable, so lost to all feelings of true honor,--can force their way into respectable society, and poison the minds of the unsullied and virtuous, may well be a matter of astonishment to those unacquainted with the desperate artfulness of human hearts. But these monsters appear not in their true character: they assume the garb and deportment of gentlemen, of philosophers, of men of education and refinement, and by their accomplishments, the suavity of their manners, their sprightliness of conversation, bewilder before they poison, and fascinate before they destroy.
