"You are sure of the hour?"
"Quite," said Betty.
"Did you see Madame Harlowe before you went?"
"Yes," Betty answered. "I went to her room just before I left. She took her dinner in bed, as she often did. I was wearing for the dance a new frock which I had bought this winter at Monte Carlo, and I went to her room to show her how I looked in it."
"Was Madame alone?"
"No; the nurse was with her."
And upon that Hanaud smiled with a great appearance of cunning.
"I knew that, Mademoiselle," he declared with a friendly grin. "See, I set a little trap for you. For I have here the evidence of the nurse herself, Jeanne Baudin."
He took out from his pocket a sheet of paper upon which a paragraph was typed. "Yes, the examining magistrate sent for her and took her statement."
"I didn't know that," said Betty. "Jeanne left us the day of the funeral and went home. I have not seen her since."
