"Six, I think. Each goes down by himself. We're to meet M. Weber at a quarter to two, near the House of Retreat."

"Very well, I shall be there."

"What?"

"Am I not leading the expedition? And isn't it my business to find M. Lenormand, seeing that I've announced it publicly?"

"Then you believe that M. Lenormand is not dead, governor?"

"I'm sure of it."

"Do you know anything?"

"Yes, since yesterday I know for certain that Altenheim and his gang took M. Lenormand and Gourel to the bridge at Bougival and heaved them overboard. Gourel sank, but M. Lenormand managed to save himself. I shall furnish all the necessary proofs when the time comes."

"But, then, if he's alive, why doesn't he show himself?"

"Because he's not free."
