He could not tell me what became of Christine or the viscount.

When I mentioned the ghost, he only laughed.

He, too, had been told of the curious manifestations that seemed to point to the existence of an abnormal being, residing in one of the most mysterious corners of the Opera, and he knew the story of the envelope; but he had never seen anything in it worthy of his attention as magistrate in charge of the Chagny case, and it was as much as he had done to listen to the evidence of a witness who appeared of his own accord and declared that he had often met the ghost.

This witness was none other than the man whom all Paris called the "Persian" and who was well-known to every subscriber to the Opera.
The magistrate took him for a visionary.
I was immensely interested by this story of the Persian.

I wanted, if there were still time, to find this valuable and eccentric witness.
