remained but the calm,
piercing look of a person deeply skilled in the knowledge of mankind;
but it was a look that abashed every one on whom it was directed. This
extraordinary man followed us at a distance, and seemed apparently to
take but little interest in what was passing.

We came to a booth where there was a lottery. The ladies bought shares.
We followed their example, and the prince himself purchased a ticket.
He won a snuffbox. As he opened it I saw him turn pale and start back.
It contained his lost key.

"How is this?" said he to me, as we were left for a moment alone.
"A superior power attends me, omniscience surrounds me. An invisible
being, whom I cannot escape, watches over my steps. I must seek for the
Armenian, and obtain an explanation from him."

The sun was setting when we arrived at the pleasurehouse, where a supper
had been prepared for us. The prince's name had augmented our company
to sixteen. Besides the above-mentioned persons there was a virtuoso
from Rome, several Swiss gentlemen, and an adventurer from Palermo in
regimentals, who gave himself out for a captain. We resolved to spend
the evening where we were, and to return home by torchlight. The
conversation at table was lively. The prince could not forbear relating
his adventure of the key, which excited general astonishment. A warm
dispute on the subject presently took place. Most of the company
positively maintained that the pretended occult sciences were nothing
better than juggling tricks. The French abbe, who had drank rather too
much wine, challenged the whole tribe of ghosts, the English lord
uttered blasphemies, and the musician made a cross to exorcise the
devil. Some few of the company, amongst whom was the prince, contended
that opinions respecting such matters ought to be kept to oneself. In
the meantime the Russian officer discoursed with the ladies, and did not
seem to pay attention to any part of conversation. In the heat of the
dispute no one observed that the Sicilian had left the room. In less
than half an hour he returned wrapped in a cloak, and placed himself
behind the chair of the Frenchman. "A few moments ago," said he, "you
had the temerity to challenge the whole tribe of ghosts. Would you wish
to make a trial with one of them?"

"I will," answered the abbe, "if you will take upon yourself to
introduce one."

"That I am ready to do," replied the Sicilian, turning to us, "as soon
as these ladies and gentlemen
