en, I owe this honour, but I wear my peacock's feathers
without scruple.

"My dear Casanova, you will dine with us, I hope. After dinner I shall
beg you to enquire of your inscrutable intelligence whether we ought to
declare ourselves in possession of the splendid diamond, or to observe
secrecy till it is reclaimed."

After this discourse papa embraced us once more and left us.

"Sweetheart," said Esther, throwing her arms round my neck, "you have an
opportunity for giving me a strong proof of your friendship. It will cost
you nothing, but it will cover me with honour and happiness."

"Command me, and it shall be done. You cannot think that I would refuse
you a favour which is to cost me nothing, when I should deem myself happy
to shed my blood for your sake."

"My father wishes you to tell him after dinner whether it will be better
to declare that they have the diamond or to keep silence till it is
claimed. When he asks you a second time, tell him to seek the answer of
me, and offer to consult the oracle also, in case my answer may be too
obscure. Then perform the operation, and I will make my father love me
all the better, when he sees that my knowledge is equal to yours."

"Dearest one, would I not do for thee a task a thousand times more
difficult than this to prove my love and my devotion? Let us set to work.
Do you write the question, set up the pyramids, and inscribe with your
own hand the all-powerful initials. Good. Now begin to extract the answer
by means of the divine key. Never was a cleverer pupil!"

When all this had been done, I suggested the additions and subtractions I
wanted made, and she was quite astonished to read the following reply:
"Silence necessary. Without silence, general derision. Diamond valueless;
mere paste."

I thought she would have gone wild with delight. She laughed and laughed
again.

"What an amazing reply!" said she. "The diamond is false, and it is I who
am about to reveal their folly to them. I shall inform my father of this
important secret. It is too much, it overwhelms me; I can scarcely
contain myself for joy! How much I owe you, you wonderful and delightful
man! They will verify the truth of the oracle immediately, and when it is
found that the famous diamond is but glittering paste the company will
adore my father, for it will feel that but for him it would have been
covered with shame, by avowing itself the dupe of a sharper. Will you
leave the pyramid with me?"
