Erik heard scuffling, followed by an scream of pain. The little Giry ran past him. In the corridor behind her, Erik saw a man doubled over in agony, holding his bleeding nose. So, the little ballet rat had been taking singing lessons, had she? Not only had La Sorelli been his apt pupil, she was now passing on her knowledge.

From the prima ballerina's room, he heard the girls chanting in chorus:

"Solar plexus
Instep
Nose and
Groin."

Erik grinned. Philippe de Chagny was taking La Sorelli for a drive in the Bois tonight. Would she sing for him, too?
