(The drawing-room.)

Ramel, the Magistrate, the Sheriff's Officer and Vernon.

Ramel Here, then, is the result so far of our inquiry, in accordance with the evidence of Felix and Marguerite. Madame de Grandchamp, in the first place, administered to her stepdaughter a dose of opium, and you, M. Vernon, who were present and saw the criminal attempt, managed to secure and lock up the cup.

Vernon
It is true, gentlemen, but—

Ramel How is it, M. Vernon, that when you witnessed this criminal attempt, you did not check Madame de Grandchamp in the fatal course which she was then pursuing?

Vernon Believe me, gentlemen, I did everything which I thought could be done with prudence, and all that my long experience suggested was attempted by me.

The Magistrate Your conduct, sir, was peculiar, and you will be called upon to explain it. You did your duty yesterday in preserving the cup as evidence; but why did you not go further?

Ramel Pardon me, M. Cordier, this gentleman is advanced in years; he is an honest and trustworthy man. (He takes Vernon aside) You have found out, I suppose, the cause of this crime.

Vernon It springs from a rivalry between two women, who have been urged on to the most violent extremes by their reckless passions. And I was obliged to keep silence on the subject.

Ramel
I know the whole business.
