Besides, if he gave them away, he would be giving himself away, also. What these two women knew, mistress and maid, they must have learned from some member of the Zouroff household.

Was there any member of that household, except himself, who had foreknowledge of the Prince’s plans? He was inclined to doubt it. Confidants he must have, when engaged in so many dark schemes, but Zouroff chose as few as possible. Yet, and yet—if only he could throw suspicion in a likely quarter, on somebody else!

Katerina, embarked on the full tide of confession and genuinely alarmed for her lover’s safety, babbled on artlessly. Peter had drawn a gloomy picture of the vengeance he might expect at the hands of his master for that innocent gossip of a few moments, when discovery came home to him, as it was sure to do. In her revelations she let fall the fact that the celebrated Madame Quéro had paid a visit to the Princess, during her brother’s temporary absence.

Peter pricked up his ears at the information. He knew full well the relations between the Prince and the handsome singer. Here was a fact that might be turned to his advantage. Madame Quéro, he felt assured, participated in all her lover’s secrets.

“Have you any proof of that?” he asked eagerly.

Katerina opened wide her tear-dimmed eyes. “Proof? Do you doubt my word? Why, she gave me her card, and the Princess handed it me back and told me to return it to her, with her excuses for not receiving her. I did not like to be so rude, and I put it in my pocket.”

“Have you still got that card, Katerina?” questioned the valet anxiously.

“Of course I have. I kept it as a souvenir. I regard her as a very distinguished person, and I hear she came from our own class. The Princess, of course, looks upon her as the dirt under her feet, but in her position there is no blame, perhaps, for her doing that.” Thus poor Katerina, divided between loyalty to her young mistress and admiration for the beautiful woman who had overcome such formidable obstacles.

The artful valet put his arm round her waist and imprinted a fond kiss on her pretty cheek.

“Katerina, my little sweetheart, I think you will admit you owe me some amends for your foolish indiscretion. Give me that card, and we will cry quits. But not a word to the Princess. But I forgot. You cannot tell her; you ought to have returned it to Madame Quéro.”
