Those who thought themselves in the know, put down the inequality of her performance to some recent tiff with Prince Zouroff. But this was only a surmise, not a fact. Zouroff, of course, was in her thoughts, but only in connection with Corsini.

It was the danger threatening the handsome young Italian that caused her to sing flat and provoke those unflattering comments amongst her usually loyal audience.

Again in the early part of the evening she had sought him in his private room, and for the second time endeavoured to dissuade him from going to the Zouroff Palace. He was convinced in his own mind that it was unworthy jealousy of the Princess Nada which had prompted her action.

Perhaps, a short time ago, he would have felt a certain amount of pity for an affection that was so thoroughly misplaced. But Golitzine’s plain hints had destroyed his former feelings of friendship. He could only regard her interference now with resentment.

He looked at her very steadily. “Give me some intelligent reason for breaking my promise, Madame, and I will go so far as to say I will consider it.”

She turned pale and bit her lip in manifest agitation. What he asked her was precisely what she could not do. After that none too veiled threat of Zouroff’s, that if she failed him he would show her no mercy, she dare not betray him by telling the truth.

But she was a woman of considerable resource and she thought she might get round him by appealing to his pride.

“I do not know that I can advance any very sufficient reason, except that we have been good friends, and it annoys me to find you refusing to place a proper value on yourself.”

“How am I making myself cheap by playing at the Zouroff Palace, Madame? Like yourself, I am an artist and follow my art; certainly because I love it, but also because it procures me a substantial reward. If I play for the Countess Golitzine and others, I can play without loss of dignity for the Princess Zouroff.”

She saw her opportunity, and took advantage of it swiftly. “I am not speaking of women, my good friend. It is the Prince himself who is in my mind. You have told me half a dozen times that this man treats you with the greatest hauteur, hardly deigns to return your salutation. He is, after all, the master of the house. It seems to me that if you respected yourself, as I should wish you to do, you would refuse to give him the chance of insulting you.”
