“Quite so.”

Mon. Gerbois and the governor henceforth maintained a discreet silence. But the secret was revealed in some way, for it was soon commonly known that Arsène Lupin had returned the lottery ticket to Mon. Gerbois. The public received the news with astonishment and admiration. Certainly, he was a bold gamester who thus threw upon the table a trump card of such importance as the precious ticket. But, it was true, he still retained a trump card of equal importance. However, if the young girl should escape? If the hostage held by Arsène Lupin should be rescued?

The police thought they had discovered the weak spot of the enemy, and now redoubled their efforts. Arsène Lupin disarmed by his own act, crushed by the wheels of his own machination, deprived of every sou of the coveted million ... public interest now centered in the camp of his adversary.

But it was necessary to find Suzanne. And they did not find her, nor did she escape. Consequently, it must be admitted, Arsène Lupin had won the first hand. But the game was not yet decided. The most difficult point remained. Mlle. Gerbois is in his possession, and he will hold her until he receives five hundred thousand francs. But how and where will such an exchange be made? For that purpose, a meeting must be arranged, and then what will prevent Mon. Gerbois from warning the police and, in that way, effecting the rescue of his daughter and, at the same time, keeping his money? The professor was interviewed, but he was extremely reticent. His answer was:

“I have nothing to say.”

“And Mlle. Gerbois?”

“The search is being continued.”

“But Arsène Lupin has written to you?”

“No.”

“Do you swear to that?”
