At first, however, neither M. de Chandore nor M. Folgat gave any answer. They were considering the question.

“Mind,” said the doctor again, shocked at their silence, “mind, I pray, that if my view is adopted, as I have every reason to hope, a new turn will be given to the whole case.”

Why yes! The ground of the accusation might be taken from under the prosecution; and that was what kept M. Folgat thinking.

“And that is exactly,” he commenced at last, “what makes me ask myself whether the discovery of Cocoleu’s rascality would not be rather injurious than beneficial to M. de Boiscoran.”

The doctor was furious. He cried,—

“I should like to know”—

“Nothing can be more simple,” replied the advocate. “Cocoleu’s idiocy is, perhaps the most serious difficulty in the way of the prosecution, and the most powerful argument for the defence. What can M. Galpin say, if M. de Boiscoran charges him with basing a capital charge upon the incoherent words of a creature void of intelligence, and, consequently, irresponsible.”

“Ah! permit me,” said Dr. Seignebos.

But M. de Chandore heard every syllable.

“Permit yourself, doctor,” he said. “This argument of Cocoleu’s imbecility is one which you have pleaded from the beginning, and which appeared to you, you said, so conclusive, that there was no need of looking for any other.”
