"In that case, Monsieur, you cannot know more about it than I do, and you must accept the verdict of the doctor."
"I am sorry, but his verdict fails to satisfy me."
"But look here, Monsieur, what prompts you to make the accusation? Have you any evidence?"
"Yes."
"What evidence?"
"Your own words, Monsieur le Préfet."
"My own words? What do you mean?"
"I will tell you, Monsieur le Préfet. You began by saying that Cosmo Mornington had taken up medicine and practised it with great skill; next, you said that he had given himself an injection which, carelessly administered, set up inflammation and caused his death within a few hours."
"Yes."
"Well, Monsieur le Préfet, I maintain that a man who practises medicine with great skill and who is accustomed to treating sick people, as Cosmo Mornington was, is incapable of giving himself a hypodermic injection without first taking every necessary antiseptic precaution. I have seen Cosmo at work, and I know how he set about things."
"Well?"
"Well, the doctor just wrote a certificate as any doctor will when there is no sort of clue to arouse his suspicions."
"So your opinion is"
"Maître Lepertuis," asked Perenna, turning to the solicitor, "did you notice nothing unusual when you were summoned to Mr. Mornington's death-bed?"
"No, nothing. Mr. Mornington was in a state of coma."
