Once alone in the carriage with his mother, Gavin clasped her in his arms, saying, “How proud I was of you! And how superior did you appear to the wretch—”

“Hush,” replied Lady Hamilton in a strained voice; and suddenly bursting into tears, she cried: “He was not always like this. I cannot, cannot think that he was always bad. He was a gallant man and a gentleman when I married him.”

Gavin remained silent, amazed and confounded at this revelation of a woman’s secret tenderness, which could survive twenty years of neglect, persecution, and unspeakable humiliation.

CHAPTER VIII

The next morning, before nine o’clock, a messenger came from the Empress Queen to St. Arnaud, commanding his immediate presence at the imperial palace.

St. Arnaud reappeared at dusk in the evening. Gavin was sitting by the window, listening with amusement to the stories Lady Hamilton was telling, in her soft, pleasant voice, to the two little girls, Freda and Gretchen.

“Make ready,” said St. Arnaud to Gavin as he came in, “to start for Breslau with me to-morrow, at midnight, with a flag of truce to the King of Prussia. I was sent for by the Empress Queen for that purpose. All is settled. I was allowed to choose a brother officer to accompany me, and I chose you.”

“A thousand, thousand thanks,” cried Gavin, who realized the advantages of being sent upon such an expedition.

“I warn you, though,” continued St. Arnaud, warming himself by the fire, as the little girls lighted the candles and Lady Hamilton and Gavin hung breathless upon his words, “our mission will fail. The King of Prussia has never been celebrated for his kindness to the unfortunate, whether prisoners, whom he generally browbeats, no matter how humble or how exalted their station, or officers of his own who do not prove always equal to victory. The Prince of Severn, who was taken prisoner while reconnoitring near Breslau last October, wishes a letter conveyed to the King of Prussia, in winter quarters at Breslau. The Prince, you must know, being an ally of Frederick’s, fully expected steps to be taken at once to secure his release on parole. But so far the King of Prussia has not written him a line, or shown the slightest interest in the fate of one of his best friends and generals. The poor Prince, tired with waiting, declares there must be some misapprehension on the King’s part, and solicited the Empress Queen to allow him to send a letter to the King at Breslau. She at once agreed, for she is as kind to prisoners and considerate of their feelings as Frederick is to the contrary. She, therefore, from the goodness of her heart, consented to transmit the letter, but, as it often is, there is sound political wisdom as well as generosity in her action; because, if Frederick wishes to befriend his ally, the Prince can be exchanged for a large number of Austrian prisoners, and if his neglect is intentional, it will place Maria Theresa’s conduct in shining contrast to her great enemy’s. The Emperor and Prince Kaunitz saw this when they agreed to her generous proposal. The Prince intimated a wish that I might be the officer sent—I was able to show him a trifling kindness once some years ago—and the Empress Queen assented with the utmost alacrity. Great and magnanimous as she is, she is woman enough to be willing to let the King of Prussia see us, his two prisoners, free and in good case. All arrangements are made. I have letters and money and horses, and we start on the stroke of midnight to-morrow. We shall probably be gone two weeks, but if we are caught by the spring floods, we shall be detained until they subside, for the Empress Queen and the King of Prussia between them have scarcely left a bridge standing in Silesia.”

Gavin was overjoyed at the prospect of an expedition of so much interest; and his mother showed her sympathy with him by at once beginning to talk over preparations. Gavin ran downstairs to Madame Ziska, who was just arranging the lamp and fire, and placing Kalenga with a book for the evening, before going to the opera.
