After their departure, I found myself much embarrassed to fulfill so many pressing and contradictory duties, the consequences of my imprudence; had I been in my natural situation, after the proposition and refusal of the journey to Geneva, I had only to remain quiet, and everything was as it should be.  But I had foolishly made of it an affair which could not remain in the state it was, and an explanation was absolutely necessary, unless I quitted the Hermitage, which I had just promised Madam d’Houdetot not to do, at least for the present.  Moreover she had required me to make known the reasons for my refusal to my pretended friends, that it might not be imputed to her.  Yet I could not state the true reason without doing an outrage to Madam d’Epinay, who certainly had a right to my gratitude for what she had done for me.  Everything well considered, I found myself reduced to the severe but indispensable necessity of failing in respect, either to Madam d’Upinay, Madam d’Houdetot or to myself; and it was the last I resolved to make my victim.  This I did without hesitation, openly and fully, and with so much generosity as to make the act worthy of expiating the faults which had reduced me to such an extremity.  This sacrifice, taken advantage of by my enemies, and which they, perhaps, did not expect, has ruined my reputation, and by their assiduity, deprived me of the esteem of the public; but it has restored to me my own, and given me consolation in my misfortune.  This, as it will hereafter appear, is not the last time I made such a sacrifice, nor that advantages were taken of it to do me an injury.

Grimm was the only person who appeared to have taken no part in the affair, and it was to him I determined to address myself.  I wrote him a long letter, in which I set forth the ridiculousness of considering it as my duty to accompany Madam d’ Epinay to Geneva, the inutility of the measure, and the embarrassment even it would have caused her, besides the inconvenience to myself.  I could not resist the temptation of letting him perceive in this letter how fully I was informed in what manner things were arranged, and that to me it appeared singular I should be expected to undertake the journey whilst he himself dispensed with it, and that his name was never mentioned.  This letter, wherein, on account of my not being able clearly to state my reasons, I was often obliged to wander from the text, would have rendered me culpable in the eyes of the public, but it was a model of reservedness and discretion for the people who, like Grimm, were fully acquainted with the things I forbore to mention, and which justified my conduct.  I did not even hesitate to raise another prejudice against myself in attributing the advice of Diderot, to my other friends.  This I did to insinuate that Madam d’Houdetot had been in the same opinion as she really was, and in not mentioning that, upon the reasons I gave her, she thought differently, I could not better remove the suspicion of her having connived at my proceedings than appearing dissatisfied with her behavior.
