Horatio thought no more on the affair of madame de Olonne and monsieur de Coigney, from the time he had been cleared of having any concern with that lady, yet was that night's adventure productive of what he looked upon as the greatest misfortune could befal him. But to make this matter conspicuous to the reader, it is necessary to give a brief detail of the circumstances that led to it.

This lady, who was wife to the baron de Olonne, was one of the most beautiful, and most vicious women in the kingdom; she entertained a great number of lovers; but there was none more attached to her, or more loved by her than young monsieur de Coigney: he had for a long time maintained a criminal correspondence with her, to the great trouble of all his friends, who endeavoured all they could, but in vain, to wean him from her: he had lately a recounter with one of her former lovers, which had like to have cost him his life; and it was with great difficulty, and as much as the relations on both sides could do, by representing to the king that they were set upon by street-robbers, that they avoided the punishment the law inflicts on duelists. De Coigney was but just recovered of the hurts he had received, when, so far from resolving to quit the occasion of them, he made an appointment to meet her at the masquerade:—they had described to each other the habit they intended to wear, when, as he was preparing for the rendezvous, an express came from the king, commanding his immediate attendance at Marli, where the court then was: this was occasioned by old monsieur de Coigney, who having, by some spies he kept about his son, received intelligence of this assignation, had no other way to disappoint it than by the royal authority, which he easily procured, as he was very much in favour with his majesty; and had laid the matter before him.

The person who came with the mandate had orders not to quit the presence of young Coigney, but bring him directly; by which means he was deprived of all opportunity of sending his excuses to madame de Olonne, who coming to the masquerade big with expectation of seeing her favourite lover, and finding him, as she imagined, engaged with others, and wholly regardless of herself, was seized with the most violent jealousy; and not able to continue in a place where she had received so manifest a slight, desired mademoiselle de Freville, her confidant and companion, to upbraid him with his inconstancy; which request she complied with in the manner already related, and which gave mademoiselle Charlotta such matter of disquiet.

The amorous madame de Olonne, however, having given vent to the first transports of her fury, could not hinder those of a softer nature from returning with the same violence as ever; and for the gratification of them wrote that letter which Horatio received, and occasioned afterward the explanation of the whole affair, which explanation he then thought fortunate for him; but by a whimsical effect of chance it proved utterly the reverse.

Mademoiselle de Coigney, who had the most tender affection for her brother, and passionately wished to make him break off all engagements with a woman of madame de Olonne's character, and who might possibly bring him under many inconveniencies, took the hint which mademoiselle Charlotta unthinkingly gave, by telling her how she had been affronted on his account by de Freville, of putting something into his head which might probably succeed better than all the attempts had hitherto been practised to make him quit his present criminal amour.

The first time she saw mademoiselle de Freville, she told her as a great secret that her brother was fallen in love with mademoiselle Charlotta, and that she believed it would be a match, for he had already engaged friends to sollicit monsieur de Palfoy on that score. This she knew would be carried directly to madame de Olonne, and doubted not but it would so increase her jealous rage, that all he could say in his defence would pass for nothing: she also added, that he was in the masquerade that night, tho' for some private reasons best known to himself, said she, he had ordered his people to give out he was gone to Marli.

De Freville, who was the creature of madame de Olonne, no sooner received this intelligence than she flew with it to her, as mademoiselle de Coigney had imagined: neither did it fail of the desired effect. When he came to visit her, as he did on the moment of his return from Marli, the violence of her temper made her break out into such reproaches and exclamations, as a man had need be very much in love to endure: he endeavoured to make her sensible of her error by a thousand protestations; but the more he talk'd of Marli and the king's command, the more she told him of Charlotta and the masquerade; and almost distracted to find he still persisted in denying he was there, or had ever made any tender professions to that lady, she proceeded to such extravagancies as he, who knew himself innocent, could not forbear replying to in terms which were far from being softening:—in fine, they quarrelled to a very high degree, and some company happening to come in at the same time, hindered either of them from saying any thing which might palliate the resentment of the other.

Before they had an opportunity of meeting again, mademoiselle de Coigney saw her brother; and artfully introducing some discourse of mademoiselle Charlotta de Palfoy, began to run into the utmost encomiums on that lady's beauty, virtue, wit, and sweetness of disposition, and at last added, that she should think herself happy in having her for a sister. Young de Coigney listened attentively to what she said: he had often been in her company, but being prepossessed with his passion for madame de Olonne, her charms had not that effect on him as now that the behaviour of the other had very much lessened his esteem of her.

He replied, that he knew no lady more deserving than the person she mentioned, and should be glad if, by her interest, he might have permission to visit her: this was all mademoiselle de Coigney wanted; she doubted not but if he were once engaged in an honourable passion, it would entirely cure him of all regard for madame de Olonne, and as she knew he had a good share of understanding, thought that when he should come to a more near acquaintance with the perfections of Charlotta, the loose airs of the other would appear in their true colours, and become as odious to him as once they had been infatuating.

Finding him so well inclined to her purpose, she took upon herself the care of introducing him, as it was indeed easy to do, considering the intimacy there was between her and Charlotta. That young lady received him as the brother of a person she extremely loved; and little suspecting the design on which he came, treated him with a gaity which heightened her charms, and at the same time flattered his hopes, that there was something in his person not disagreeable to her.
