Gaston Leroux: The Mystery of the Yellow Room

CHAPTER 8: The Examining Magistrate Questions Mademoiselle Stangerson (continued)

"Q. It was during that hour, no doubt, that the murderer got into the pavilion. But how? Nobody knows. Footmarks have been found in the park, leading away from the window of the vestibule, but none has been found going towards it. Did you notice whether the vestibule window was open when you went out?

"A. I don't remember.

"Monsieur Stangerson. It was closed.

"Q. And when you returned?

"Mademoiselle Stangerson. I did not notice.

"M. Stangerson. It was still closed. I remember remarking aloud: 'Daddy Jacques must surely have opened it while we were away.'

"Q. Strange! - Do you recollect, Monsieur Stangerson, if during your absence, and before going out, he had opened it? You returned to the laboratory at six o'clock and resumed work?

"Mademoiselle Stangerson. Yes, monsieur.

"Q. And you did not leave the laboratory from that hour up to the moment when you entered your chamber?

"M. Stangerson. Neither my daughter nor I, monsieur. We were engaged on work that was pressing, and we lost not a moment, - neglecting everything else on that account.

"Q. Did you dine in the laboratory?

"A. For that reason.

"Q. Are you accustomed to dine in the laboratory?

"A. We rarely dine there.

"Q. Could the murderer have known that you would dine there that evening?
