He had the strength to pronounce those two syllables without removing his eyes from the other, who could not restrain a contraction of his bushy eyebrows and a curl of his lip as he replied:-- "I am at your service so far as this question does not run counter to my duty as a physician. We have a duty of absolute silence, which you do not suspect," he continued with a peculiar bitterness: "nec visa, nec audita, nec intellecta[7] is the old form of the Hippocratic oath. It is still true." "It is a very simple matter," rejoined Landri. "You are aware that Monsieur de Claviers is Monsieur Jaubourg's legatee. We have obtained proof that some papers of great importance were taken from his apartment during the last days of his illness. Well! I would be glad to have your word--" "That I didn't take them?" the doctor hastily interrupted. "Don't tell me that you came here to ask me that," he continued with an outburst of anger; "I will not allow it." "You might have let me finish my sentence," retorted Landri, more calmly, but very little more. Being absolutely ignorant of the inward tragedy--so like his own, alas!--of which Pierre Chaffin was the victim, this outbreak at the bare idea of a suspicion of dishonesty was inexplicable to him. He had said nothing to justify it, and being rendered so sensitive by his own suffering, he could not brook a reply uttered in such a tone. "I finish that sentence. I would be glad to have your word, not that you did not take the papers, but simply that no person, to your knowledge, entered Monsieur Jaubourg's bedroom during his illness,--besides the servants, Professor Louvet, and yourself, of course. It seems to me that there is nothing in that to cause any sensitiveness on your part. It is simply a matter of preventing suspicion from going astray. You should be the first to desire it." "I have no answer to make to a question of that sort," said Pierre. He did not clearly discern his questioner's object. It was true that he would have no right to take offence at the question, if it had not been couched in terms too imperious and inquisitorial. The conclusion especially had irritated him. But as Landri had affected to speak in a very self-contained tone, almost ceremonious in its stiffness, he determined to meet his coldness with equal coldness. He would have been humiliated to appear less able to control his nerves, or less polished, than the young noble, and he added: "I do not admit that it is the duty of a physician to keep watch over his patient otherwise than professionally. I venture to assert that I treated Monsieur Jaubourg to the best of my ability, and that is all that his heirs have a right to concern themselves about with respect to me." "It is not a question of keeping watch," Landri replied. "You compel me, in spite of myself, to make my questions more precise. Did you admit no stranger to the invalid's bedroom? For you did receive visitors, I know from Joseph."
