Then offering his hand to the farmer, who pressed it respectfully in his, he added:

"Bring Vera to-morrow morning to Pampeln; we will start at once for Mittau, and take the night train thence to Paris. Again I thank you. Adieu till to-morrow."

The prince, who had spoken the last words as he stood on the threshold of the door, sprung upon his horse and rode off in the direction of the château.

Next day, before ten o'clock, Soublaieff was at Pampeln with his daughter. At noon the young Russian girl and Pierre Olsdorf got into a post-chaise, on the box-seat being Yvan, his old and faithful body-servant; and Soublaieff, with tearful eyes, saw them drive off, as he murmured:

"Perhaps I was wrong to yield, but he seemed so unhappy. What is the mystery? God preserve my child."

CHAPTER VII.
AT THE OPERA COMIQUE.

Two days later Pierre Olsdorf arrived in Paris, at a quarter past seven in the evening, by the Cologne express. He had traveled without a break. By eight o'clock he was at the Grand Hotel, and in ten minutes' time, Yvan, his body-servant, was on his way to the Rue Lafitte with a letter which he was to deliver in person to the princess, if she were at home, or to leave with a servant to be taken at once to his mistress, if it were known where she was passing the evening. The prince did not wish his letter to be read by a lady's-maid before it reached its address.

At the Rue Lafitte, Yvan was told that the princess had just gone to the Opera Comique, and a promise was made that a footman should go to the theater immediately with the letter.

The man, indeed, started at once, and the prince's servant, on his way back to the boulevard, saw him turn down the Rue Marivaux.

A stock-piece was being played this evening. The princess was seated at the front of the box, while Paul Meyrin, who was her companion, sat behind her. As usual she was listening attentively to the music when the door of the box opened. Rather surprised, for she was expecting nobody, at least until between the acts, the young woman turned round and took from the hat, held salver-wise, of her footman the letter he offered to her.
