"Then," said the examining-magistrate, "after killing the President, on account of an intimacy that dated back some time, which was of a vague nature and which for that matter you invent, explain to me how it was that you allowed your wife to have a sweetheart. Yes; that strapping fellow Jacques Lantier! Everybody has spoken to me about this acquaintance. You, yourself, have not attempted to conceal from me that you were aware of it. You freely allowed them to do what they pleased. Why?" Roubaud, overcome and with troubled eyes, looked fixedly into space without finding an explanation, and ended by stammering: "I do not know. I killed the other; I did not kill this one." "Then," concluded the examining-magistrate, "do not tell me, again, that you are a jealous man who avenges himself. And I do not advise you to repeat this romance to the gentlemen of the jury, for they would only shrug their shoulders. Believe me, change your system. Truth alone can save you." Henceforth, the more Roubaud stubbornly told this truth, the greater liar he was proved to be. Besides, everything went against him, and to such a point that his previous examination, on the occasion of the first inquiry in connection with the Grandmorin murder, which should have served to support his new version of the crime, because he had denounced Cabuche, became, on the contrary, the proof of a remarkably clever understanding between them. The examining-magistrate refined the psychology of the affair with a veritable passion for his calling. Never, said he, had he penetrated so thoroughly to the bottom of human nature; and it was by divination rather than observation, for he flattered himself he belonged to the school of far-seeing and fascinating judges, those who have the power of upsetting a man by a glance. Besides, proofs were no longer wanting, and conjointly formed a crushing charge. Henceforth, the prosecution were in possession of a solid basis to work upon, and the certainty of the guilt of the prisoners burst forth in dazzling brightness like the light of the sun.
