Donatien-Alphonse-François, Marquis de SADE. L.A.S., [Saint-Ouen] 20 fructidor [VII (September 6, 1799)]; 1page in-4. Rare letter on Justine, of which he denies authorship. "It is impossible for Md Quenet to have promised you Justine, for not only does she not have any at her disposal, but she is convinced that this work is not mine, and she also knows that I do not have any at mine; believe me Monsieur, do not be curious about this very bad book, it makes you cry, and if I had had the misfortune, in a moment of delirium, to create it, I would have enough reason today to cut off the hand that would have written it"... He is "in a very cruel frame of mind", while Madame Quesnet is in Provence: "the awful troubles of this country make me worry for her, and my anxiety is beyond expression"...
