“This dungeon,” said the concierge, “was, it appears, some time ago occupied by a very dangerous prisoner, the more so since he was full of industry. Another person was confined in the Château at the same time, but he was not wicked, he was only a poor mad priest.”

“Ah, indeed?—mad!” repeated Monte Cristo; “and what was his mania?”

“He offered millions to anyone who would set him at liberty.”

Monte Cristo raised his eyes, but he could not see the heavens; there was a stone veil between him and the firmament. He thought that there had been no less thick a veil before the eyes of those to whom Faria offered the treasures.

“Could the prisoners see each other?” he asked.

“Oh, no, sir, it was expressly forbidden; but they eluded the vigilance of the guards, and made a passage from one dungeon to the other.”

“And which of them made this passage?”

“Oh, it must have been the young man, certainly, for he was strong and industrious, while the abbé was aged and weak; besides, his mind was too vacillating to allow him to carry out an idea.”

“Blind fools!” murmured the count.

“However, be that as it may, the young man made a tunnel, how or by what means no one knows; but he made it, and there is the evidence yet remaining of his work. Do you see it?” and the man held the torch to the wall.
