Madame Denis then observed: 

“A week ago a Piedmontese, named Audar, was introduced to me.  He had been a chief mover in the conspiracy, and the empress gave him a present of a hundred thousand roubles and an order to leave Russia immediately.”

I heard afterwards that this Audar bought an estate in Piedmont on which he built a fine mansion.  In two or three years it was struck by a thunder-bolt, and the unfortunate man was killed in the ruins of his own house.  If this was a blow from an Almighty hand, it could not, at all events, have been directed by the genius of Russia, for if the unfortunate Peter iii. had lived, he would have retarded Russian civilization by a hundred years.

The Empress Catherine rewarded all the foreigners who had assisted her in her plots most magnificently, and shewed herself grateful to the Russians who had helped her to mount the throne; while, like a crafty politician, she sent such nobles as she suspected to be averse to revolution out of the country.

It was Da Loglio and his pretty wife who determined me to betake myself to Russia in case the King of Prussia did not give me any employment.  I was assured that I should make my fortune there, and Da Loglio promised to give me good instructions.

As soon as this worthy man left Berlin my intimacy with Madame Denis commenced.  One night when I was supping with her she was seized with convulsions which lasted all the night.  I did not leave her for a moment, and in the morning, feeling quite recovered, her gratitude finished what my love had begun twenty-six years before, and our amorous commerce lasted while I stayed at Berlin.  We shall hear of her again at Florence six years later.

Some days after Madame Denis took me to Potsdam to shew me all the sights of the town.  Our intimacy offended no one, for she was generally believed to be my niece, and the general who kept her either believed the report, or like a man of sense pretended to believe it.

Amongst other notable things I saw at Potsdam was the sight of the king commanding the first battalion of his grenadiers, all picked men, the flower of the Prussian army.

The room which we occupied at the inn faced a walk by which the king passed when he came from the castle.  The shutters were all closed, and our landlady told us that on one occasion when a pretty dancer called La Reggiana was sleeping in the same room, the king had seen her in ’puris naturalibus’.  This was too much for his modesty, and he had ordered the shutters to be closed, and closed they had remained, though this event was four years old.  The king had some cause to fear, for he had been severely treated by La Barbarina.  In the king’s bedroom we saw her portrait, that of La Cochois, sister to the actress who became Marchioness d’Argens, and that of Marie Theresa, with whom Frederick had been in love, or rather he had been in love with the idea of becoming emperor.
