"You are sure it was poison he required?"
"I am sure."
"And madame?"
"A love-philtre."
"You heard both interviews?"
"Both."
"You are sure of the arrangement made between Vidoche and this man, of which you have told us? That the poison should be given to madame in the form of a love-philtre? That she might take it herself?"
"I am sure."
"And it was you who ran after Madame de Vidoche and told her that the draught was to be given to her husband instead?"
"Yes."
