I spoke to him about it when night had come on, and we were once more in his room.

He replied that all his arrangements had already been made, and this time the murderer would not get away from him.
I expressed some doubt on this, reminding him of his disappearance in the gallery, and suggested that the same phenomenon might occur again.
He answered that he hoped it would.

He desired nothing more.

I did not insist, knowing by experience how useless that would have been.

He told me that, with the help of the concierges, the chateau had since early dawn been watched in such a way that nobody could approach it without his knowing it, and that he had no concern for those who might have left it and remained without.
It was then six o'clock by his watch.
