est. What is a servant who does not warn his master under such
circumstances but a rascal? Indeed I am absolutely certain that he was
the informer, for he was the only person who knew where the arms were
concealed."

Mengs could find no answer to this, and left to go to bed. I did the same
and had an excellent night.

Early the next morning the great Mengs sent me linen and all the
requisites of the toilette. His maid brought me a cup of chocolate, and
his cook came to ask if I had permission to eat flesh-meat. In such ways
a prince welcomes a guest, and bids him stay, but such behaviour in a
private person is equivalent to a hint to go. I expressed my gratitude,
and only accepted a cup of chocolate and one handkerchief.

My carriage was at the door, and I was just taking leave of Mengs when an
officer appeared on the scene, and asked the painter if the Chevalier de
Casanova was in his house.

"I am the Chevalier de Casanova," said I.

to do so after you have reached the prison."

"Very good; then I am ready to follow you, for I have no choice. I shall
remember Spanish justice!"

I embraced Mengs, had the weapons put into my carriage, and got in with
the officer, who seemed a perfect gentleman.

He took me to the Castle of Buen Retiro, formerly a royal palace, and now
a prison. When my conductor had consigned me to the officer of the watch
I was handed over to a corporal, who led me into a vast hall on the
ground floor of the building. The stench was dreadful, and the prisoners
were about thirty, ten of them being soldiers. There were ten or twelve
large beds, some benches, no tables, and no chairs.

I asked a guard to get me some pens, ink, and paper, and gave him a duro
for the purpose. He to
