“You will not?” inquired Westerham with a little laugh. “Surely it was part of our agreement that you should introduce me to all your friends. If you fail to keep that agreement, then I shall fail to keep mine; and I fancy that some of the authorities will be extremely interested in what I shall be able to tell them.” Melun looked helplessly and almost pleadingly at Westerham. “But what you ask now,” he complained, “is quite impossible.” “Why?” Melun mumbled, and Westerham's quick mind instinctively found the right reason for the captain's distress. He debated whether he should mention the Hyde Park affair of the night before. Had Bagley told him? He was doubtful. And if Bagley had not told then the revelation might be awkward. He had no wish to drive Melun so hard that he would turn and become obstinately intractable. Moreover, if he said anything then he would certainly never discover from Melun what hold he had upon Lady Kathleen and her father. It would be better, he reflected, to smooth matters over and let events take their own course. In following his method, he felt assured the opportunity of fathoming the mystery must inevitably come to him. So when he spoke next to Melun it was a little less curtly. “You will hardly deny,” he said, “that your presence in Lord Penshurst's house must be unwelcome. Do you hesitate to take me there because you think that in so doing I might possibly be tarred with the same brush as yourself?” “What do you mean?” asked Melun, savagely, and there crept into his eyes an embarrassed, even a hunted look. “I meant nothing at all except that, in spite of everything, you must make it convenient to have me included among the guests.” Melun appeared to think deeply for a few moments and then nodded acquiescence. “Very well,” he said grumpily, and closed the matter for that night. On the following evening Melun arrived at the Walter's Hotel sleek and smiling. His face was as smooth as his shirt-front, and his manner as pleasant as the cut of his coat. Westerham met him in the hall and nodded to him with an almost friendly smile. Presently they drove down to Downing Street. When Lady Kathleen had entered into possession of No. 10 as hostess she had turned the rather dowdy old house upside down, and decorators and upholsterers had done all they could to make the old-fashioned building pleasant and graceful. It was now about half-past ten, and the crush was very great. The Prime Minister, handsome and white-bearded, stood apart with Lady Kathleen to receive the guests. As Melun pressed forward his gaze darted in all directions as though in the endeavour to find the eyes of friends or at least acquaintances. And many men nodded to him and many women smiled on him. Though he had been away from England so long, all Westerham's knowledge of great social events came back to him, and he followed Melun easily and unembarrassed by the scores of eyes which looked at him with questioning and admiration.
