over, my boy, while you are dispatching the prince, the mamma and the fair victim's ambition to become a real live princess.” “Don't be sarcastic, Bob,” exclaimed Quentin. “I'll not need your castle. We're going to live in the clouds.” “Beware of the prince,” said Lady Frances. “He is pretty high himself, you know.” “Let the prince beware,” laughed back the departing guest. “We can't both live in the same cloud, you know. I'll push him off.” On the day Quentin left Paris for Brussels he came face to face with Prince Ugo on one of the Parisian boulevards. The handsome Italian was driving with Count Sallaconi and two very attractive ladies. That the meeting was unexpected and undesired was made manifest by the anxious look which the prince shot over his shoulder after the carriage had passed. When Quentin left Paris that night with Turk and his luggage, he was not the only passenger bound for Brussels. At the Gare du Nord two men, one suspiciously like the Duke Laselli, took a compartment in the coach just ahead of Quentin. The train was due to reach Brussels shortly after midnight, and the American had telegraphed for apartments at the Bellevue. There had been a drizzle of rain all the evening, and it was good to be inside the car, even if the seats were uncomfortable. Turk and his master were the only passengers in the compartment. The watchful eyes of the former had seen several persons, men and women, pass through the aisle into which the section opened. One woman paused at the entrance as if about to enter. She was fair to look upon and Turk gallantly moved, presenting a roomy end of his seat to her. She passed on, however, and the little ex-burglar glanced sharply at his master as if to accuse him of frightening the fair one away. But Quentin was lying back, half-asleep, and there was nothing repellent about the untroubled expression on his face. Before reaching Le Cateau the same lady passed the entrance and again glanced inside. Turk was now asleep, but his master was staring dreamily toward the aperture leading to the aisle. He saw the woman's face for an instant, and it gradually dawned upon him that there was something familiar about its beauty. Where had he seen her before? Like
