 "I can do it, Monsieur Robert Darzac, because I know more than you do!"

"Come! Come!" murmured Darzac, almost angrily.

"Have no fear! I shall know only what will benefit you."

"You must know nothing, young man, if you want me to be grateful."

Rouletabille shook his head, going close up to Darzac.

"Listen to what I am about to say," he said in a low tone, "and let it give you confidence. You do not know the name of the murderer. Mademoiselle Stangerson knows it; but only half of it; but I know his two halves; I know the whole man!"

Robert Darzac opened his eyes, with a look that showed he had not understood a word of what Rouletabille had said to him. At that moment the conveyance arrived, driven by Frédéric Larsan. Darzac and the gendarme entered it, Larsan remaining on the driver's seat. The prisoner was taken to Corbeil.
