"Goodness gracious me!" he cried. "Why, it was the plague of the office! One of my predecessors, Maître Turbon, was summoned to Passy no fewer than eighteen times, between 1820 and 1843, by the groups of heirs, whom fortune-tellers, clairvoyants, visionaries, impostors of all sorts had promised that they would discover the farmer-general's treasures. At last, we laid down a rule: any outsider applying to institute a search was to begin by depositing a certain sum."

"What sum?"

"A thousand francs."

"And did this have the effect of frightening them off?"

"No. Four years ago, an Hungarian hypnotist tried the experiment and made me waste a whole day. After that, we fixed the deposit at five thousand francs. In case of success, a third of the treasure goes to the finder. In case of failure, the deposit is forfeited to the heirs. Since then, I have been left in peace."

"Here are your five thousand francs."

The lawyer gave a start:

"Eh? What do you say?"

"I say," repeated Lupin, taking five bank-notes from his pocket and calmly spreading them on the table, "I say that here is the deposit of five thousand francs. Please give me a receipt and invite all the d'Ernemont heirs to meet me at Passy on the 15th of April next year."

The notary could not believe his senses. I myself, although Lupin had accustomed me to these surprises, was utterly taken back.
