The donjon of Vincennes was considered very unhealthy and Madame de Rambouillet had said that the room in which the Marechal Ornano and the Grand Prior de Vendome had died was worth its weight in arsenic -- a bon mot which had great success.

You need not hurry when the object is only to prevent my saying a bon mot, for there is not the least wit in my nature.

With my southern temperament, warped by the life I led in Paris, I should certainly have come to look without pity on an unhappy girl betrayed by her lover; I should have laughed at the story if it had been told me by some wag in merry company (for with us in France a clever bon mot dispels all feelings of horror at a crime), but all sophistries were silenced in the presence of this angelic creature, against whom I could bring no least word of reproach.
