There was a ghost and was known as the Phantom. He requested unreasonable things like 20 000 francs per month and reservation to Box 5 for every show. He threatens that if they do not do what he ask for them, he would cause catastrophe. A scene shifter, Joseph Boquet was dead. Some said that it was a suicide because he hung himself and some said that it was the Phantom's doing. The old managers were retiring and the new managers, Armand Moncharmin and Firmin Richard, were here and this is going to cause trouble because MM. Richard and Moncharmin won't do what the Phantom wants them to do.
