“But I will tell you the reason, nevertheless. We have been recalled to St. Petersburg; we leave London next week. That is the reason my brother Boris is not here; he is winding up affairs for his successor.”

A deeper flush spread over Nello’s face. “But that is very strange. I am going there myself. I start next Monday.”

The young Princess looked pleased. She turned to her mother. “Signor Corsini must call upon us, mother.” She looked at him with a little smile. “To-night will not then be the last time I shall hear that lovely romance.”

The elder woman seconded the invitation warmly. “You shall come and play for us, Signor. I think you will find the Slav temperament a little more fervent than the Anglo-Saxon one.”

Nello thought this a good time for explanations. Degraux would spread the news about in his world, the Zouroffs would spread it about in theirs.

“You know, of course, the Baron Salmoros?”

The Princess replied that they had a slight acquaintance with that distinguished financier.

“Lady Glendover introduced me to him. He is a very considerable amateur, he has been kind enough to take a very warm interest in me. He is going to push my fortunes in Russia.”

“His name is one to conjure with in Russia,” said the grey-haired Princess. “He stands very high in the favour of his Imperial Majesty.”

Princess Nada nodded him farewell. “It is not good-bye, then, only au revoir. I suppose artists and ambassadors are the greatest cosmopolitans on earth. We shall meet next in St. Petersburg.”
