She is, I presume, a professional, as she is singing here.

My desire to make her acquaintance is purely actuated by business motives." Tavernake moved away toward the waiting-room.
The man, who according to his card was Mr.Sidney Grier, would have followed him in, but Tavernake stopped him.
"If you will wait here," he suggested, "I will see whether my sister desires to meet you." Once more Mr.Sidney Grier looked surprised, but after a second glance at Tavernake he accepted his suggestion and remained outside.

Tavernake took the card to Beatrice.
"Beatrice," he announced, "there is a man outside who has heard you sing and who wants to be introduced." She took the card and her eyes opened wide.
"Do you know who he is ?" Tavernake asked.
"Of course," she answered.

"He is a great producer of musical comedies.
Let me think." She stood with the card in her hand.

Some one else was singing now--an ordinary modern ballad of love and roses, rapture and despair.
