As Zena said, it sounded a lame story, but Lanning believed it. Winbush had been connected with the family all his life, was devoted to him, and it was not likely he would know what the case contained. Lanning could only suppose that some man at the works had turned traitor, while Mr. Nixon gave it as his opinion that either France or Germany had pulled the strings of the robbery. Acting under Quarles's instructions, I had an interview with Miss Chilcot. She corroborated Lanning's story in every detail so far as she was concerned, and incidentally I understood there was no more than a lover's quarrel between them. She had sat out with the young Silesian on purpose to annoy Richard. Certainly they had talked of aeroplaning; it was natural, since two days before she had seen some flying at Ranelagh, but Lanning's name had not been mentioned. Miss Chilcot knew nothing about the experiments which had taken place, nor was she aware that her lover was responsible for some of the improvements which had been made in stabilizers. Rather inconsequently she was annoyed that he had not confided in her. Miss Chilcot carried with her a faint odor of Parma violets. Quarles had told me to note particularly whether she used any kind of perfume. I was convinced of two things; first, that she was telling the truth without concealing anything, and, secondly, that Mr. Lanning was likely to marry a very charming but rather exacting young woman. When I said so to Quarles he annoyed me by remarking that some women were capable of making lies sound much more convincing than the truth. I did not attempt to get an interview with Mademoiselle Duplaix, but I made inquiries concerning her, and had a man watching her movements. Apparently she was the daughter of a good French family, and was making a prolonged stay with the Payne-Kennedys, who moved in very good society. You may see their name constantly in the _Morning Post_. It was whispered that they were not above accepting a handsome fee for introducing a protegee into society, a form of log-rolling which is far more prevalent than people imagine. Whether the girl's entrance into London society had been paid for or not I am unable to say, but she had quickly established herself as a success. It was generally agreed that she was both witty and charming, the kind of girl men easily run after, but not the sort they usually marry. She had evidently managed to cause dissension in various directions, so the suggestion that there was something of the adventuress about her might be nothing more than a spiteful comment. It justified us in keeping a watch upon her, but I had no definite opinion in the matter, not having seen the lady, and, as Quarles said, a fascinating foreigner is easily called an adventuress.
