M. Moncharmin is one of the managers during the time of this novel. He understands nothing of the ghost or his ways. He cannot understand a single note of music and does little or nothing in the actual running of the Opera House. He is, however, well connected socially.
He, like his partner, is more inclined to think low of others than to believe in the Opera ghost.
The Opera Ghost drove the last pair of managers during the Opera Ghost’s residence in the Opera House to near-madness and perhaps beyond.
