He asked for permission to leave the court of Frederick, pleading business at Paris, and also that his health required him to visit Plombières, in order to drink of its waters. Frederick gave him leave to go. On the eve of going, in utter disregard of his promise to the king, he fired a parting shot at Maupertuis, in the shape of a supplement to the attack he had already made, then travelled leisurely on his way. Frederick waited until he reached Frankfort; there he was detained by order of the king on the charge of having some verses written by Frederick in his possession. The resident at Frankfort was as stupid and clumsy as a German official can be, and managed the affair in a most rude and indelicate manner. Exasperated at the delay, Voltaire committed the folly of undertaking to steal away. He and his niece were arrested and imprisoned in an inn, where they were subjected to very unpleasant treatment. The action of Frederick was unworthy of a king. Its meanness was intensified by the bungling stupidity of the resident. The people of Frankfort grew indignant, and the burgomaster began to show resentment, for Frankfort was a free city and the King of Prussia had no right to trespass upon its privileges. It was mean in a monarch to strike this foul blow because he had been pricked with a sharp pin.
From this time forth Voltaire entered upon a life of complete independence, free from all incumbrances of mistresses, royal patrons, or aristocratic friends. He tried residence in Geneva and Lausanne, but while he found political liberty, he was not accorded by the pious Swiss the social freedom to which he was accustomed in France. Finally he purchased a place at Ferney. His home here became the Mecca to which the literary celebrities of Europe made pilgrimages. At Ferney he established watch-manufacturing, competing with the Swiss; here also he built a church, inscribing upon it "_Deo crexit Voltaire_." In pure mischievousness he entered upon an indecent controversy with the bishop of the diocese, who was a good though foolish man. He also managed to quarrel right and left with all sorts of people, while slowly and imperceptibly old age crept upon him. Much of the noblest work of his life was done here. It was while at Ferney that he adopted a young girl of noble but poor family, rescuing her from a convent and marrying her to the Marquis de Villete. She contributed to making many of his declining years bright with her presence. His pet name for her was "Belle et Bonne."
