She forgot everything, in order to triumph once more.
From that moment the prima donna sang with all her heart and soul.

She tried to surpass all that she had done till then; and she succeeded.
In the last act when she began the invocation to the angels, she made all the members of the audience feel as though they too had wings.
In the center of the amphitheater a man stood up and remained standing, facing the singer.

It was Raoul.
"Holy angel, in Heaven blessed ..." And Christine, her arms outstretched, her throat filled with music, the glory of her hair falling over her bare shoulders, uttered the divine cry: "My spirit longs with thee to rest!" It was at that moment that the stage was suddenly plunged in darkness.
It happened so quickly that the spectators hardly had time to utter a sound of stupefaction, for the gas at once lit up the stage again.

But Christine Daae was no longer there! What had become of her?
What was that miracle?
All exchanged glances without understanding, and the excitement at once reached its height.
Nor was the tension any less great on the stage itself.

Men rushed from the wings to the spot where Christine had been singing that very instant.
