"Is it not absurd to suppose that if he really died at the time and place mentioned, he would have been laid in the ground without the pomp and ceremony, the official supervision, the police registration which attend the funerals of men of his rank and notoriety? Where are these data? He passed out of public sight more than a century ago, yet no memoir contains them. A man who so lived in the full blaze of publicity could not have vanished, if he really died then and there, and left no trace behind. Moreover, to this negative we have the alleged positive proof that he was living several years after 1784. He is said to have had a most important private conference with the Empress of Russia in 1785... and to have appeared to the Princess de Lamballe when she stood before the tribunal, a few moments before she was struck down with a billet, and a butcher-boy cut off her head; and to Jeanne Dubarry, the mistress of Louis XV. as she waited on her scaffold at Paris the stroke of the guillotine in the Days of Terror of 1793."
