On Saturday morning,
Moncharmin and
Richard receive a letter from
the Phantom reminding them of his conditions. He tells them that his box must be liberated; that
Christine Daaé should sing Marguerite, since
Carlotta will be ill; that
Mme Giry must return; and that he wants to make plans about receiving his money. He threatens to “curse” the performance of
Faust if these terms are not respected.
