Epilogue

Long after the case was pigeonholed by the unintelligent care of M. le
Juge d'Instruction Faure, the newspapers made efforts, at intervals, to
fathom the mystery. One evening paper alone, which knew all the gossip
of the theaters, said: "We recognize the touch of the Opera ghost."

And even that was written by way of irony.

The Persian alone knew the whole truth and held the main proofs, which
came to him with the pious relics promised by the ghost. It fell to my
lot to complete those proofs with the aid of the daroga himself. Day
by day, I kept him informed of the progress of my inquiries; and he
directed them. He had not been to the Opera for years and years, but
he had preserved the most accurate recollection of the building, and
there was no better guide than he possible to help me discover its most
secret recesses. He also told me where to gather further information,
whom to ask; and he sent me to call on M. Poligny, at a moment when the
poor man was nearly drawing his last breath. I had no idea that he was
so very ill, and I shall never forget the effect which my questions
about the ghost produced upon him. He looked at me as if I were the
devil and answered only in a few incoherent sentences, which showed,
however--and that was the main thing--the extent of the perturbation
which O. G., in his time, had brought into that already very restless
life (for M. Poligny was what people call a man of pleasure).
