Lord Prelice looked after him somewhat puzzled. He could quite understand why Haken did not want his wife to know of his presence in Alexander Mansions; but it was difficult to account for the old man's agitation and quite unnecessary explanations. As a rule, Haken was extremely reticent, and on such an important matter as a secret meeting with a Continental diplomatist, would be much more so. Yet he had gone out of his way to set himself right with his nephew, and by telling his private business, when a gay excuse of needing a night off, would have been sufficient to account for his presence. However, Prelice simply shrugged his shoulders, and did not deem the incident worth remembering. Why should not Simon Haken enjoy himself in this way if he liked, and turn Mrs. Rover's ballroom into an office, wherein to meet his foreign clients? All the same--and Prelice gave this a passing thought--it was strange that the chance meeting with one who knew him should so upset him. And it was still stranger that, if Mr. Haken wished to preserve his incognito, he should have arrived unmasked. Having lost both his uncle and his charming blue domino, Prelice took a tour through the rooms in search of further adventures. He could only afford a few minutes, since he had to call upon Shepworth at eleven o'clock, and it was already that hour, as he had told Haken. Still, a few minutes more or less would not matter, and Prelice wished to see if he could espy Mrs. Dolly Rover, in order to renew his acquaintance with her and to compliment her on the success of her ball. And it undoubtedly was a success, for everyone seemed highly amused, and the laughter and small talk went on incessantly. Many people were dancing to the music of a gaily uniformed Hungarian Band, and many more were ensconced in flirtation corners, making the best of the hour which would elapse before everyone unmasked for supper. Prelice therefore wandered leisurely throughout the two flats, exchanging a few chaffing words with the different women who addressed him, and looking for the tall form of his hostess. Alas! there were many tall women, who looked as imperial and graceful as Mrs. Rover, and Prelice felt like Ali Baba's robber when he examined Morgiana's chalk-marks on the various doors. He therefore began, by way of some diversion, to admire the costumes of the women, which showed themselves more or less plainly from under the flowing dominos of silk. In fact, the heat of the night and of the rooms was so great that many ladies loosened the strings and buttons of their dominos, and permitted their frocks to be plainly seen. They would have removed their masks also in some cases, so stifling was the perfumed air; but the rule of the ball stopped them from doing so. Still, as many revealed the gowns they were wearing, it was probable that some would pay for their flirtatious sins when the supper hour and recognition came.
