Du Châtelet begins telling d’Argental of a letter in which it was stated that Voltaire would have been arrested a long time ago had it not been for her family’s good reputation. She notes that her protection of him is not infallible and discusses her concerns that it was a member of her family who informed the ministry, likely the Marquis de Breteuil. She questions whether or not she should move to Paris, and asks for d’Argental’s advice.
