But the consequences of her folly were not ended. Rousseau defamed her character in the ‘Confessions,’ and in that unique masterpiece of scurrility he speaks of Grimm as ‘a tiger whose fury increases daily.’ Diderot declared that Jean Jacques made him believe in the existence of the devil and of hell. But Grimm wrote an obituary notice of Rousseau in his ‘Correspondence’ of admirable justice and moderation, and spoke of him as ‘embittered by sorrows which were of his own making but not the less real,’ and as ‘a soul at once too weak and too strong to bear quietly the burden of life.’ It must be allowed that Grimm could be magnanimous. Having saved Madame d’Épinay from her friends, it remained to him to save her from herself. At Geneva he put her under the care of the great and good Tronchin, and made her write for the ‘Correspondence.’ He helped her to manage the miserable remains of the fortune her husband’s mad extravagance had left her, supervised the education of her children, and even showed her the harm she did them by speaking disrespectfully of their father. His love was not fervent, perhaps, but it corrected her follies and her weakness, and made her do and be her best. It had at least some of the tokens of a good and honourable feeling. These visits to Geneva were undoubtedly the happiest time in her life. On this first one, which lasted eight months, from February to October 1759, she and Grimm often saw and talked with Voltaire; and Grimm greatly appreciated the society of the solid and sensible Genevans and the cultivated Tronchins. Mademoiselle Fel came to stay with Voltaire at Les Délices, and when Grimm saw her there he proved convincingly the truth that ‘the man’s love, once gone, never returns.’ But his real passion was not even for Madame d’Épinay. His dominant taste was his ambition; his dearest mistress, his career. Already secretary to the Duke of Orleans, on the last evening of his stay at Geneva, he heard the satisfactory news that he was made Envoy for Frankfort at the Court of France. True, _M. l’Ambassadeur_, as Diderot called him, soon lost his post by joking in a despatch at the expense of an official person; but none the less he was rising in the world. Presently he was busy settling M. d’Épinay’s bankruptcy and helping Madame to arrange a satisfactory marriage for her daughter. _Tyran le Blanc_ he was called by her and her circle. But, after all, no woman is happy till she has met her master. Well for her if she find one as judicious and upright as Melchior Grimm. He was less with her as the years went by, though not in any sense less faithful. In 1762 the Duchess of Saxe-Gotha appointed him her _chargé d’affaires_; and when she died her husband made him Councillor of Legation, with a pension.
