“That is because you have not had time to reflect, Monsieur le Juge d’Instruction. The great thing is to reflect. Facts very seldom fail to carry their own explanation!”

“And, according to you, the facts which we have just ascertained carry their own explanation?”

“Don’t you think so yourself? In any case, I have ascertained none besides those which are set down in the official report.”

“I should answer that I know.”

“Bravo! My gentleman knows more about it than the owner himself. M. de Gesvres has everything accounted for: M. Isidore Beautrelet has not. He misses a bookcase in three sections and a life-size statue which nobody ever noticed. And, if I asked you the name of the murderer?”

“I should again answer that I know it.”

“You know the murderer’s name?”
