She was tall, slender, gowned in the most modish manner, and had a foreign way about her that would have fascinated one even more cosmopolitan than a Texas veterinary.

Now and then someone would stop and chat with them and it seemed that they were on very good terms, at least with a certain group at the St. Quentin.

Kennedy moved out further into the lobby where he was more noticeable; then, with a sudden resolution, mounted the steps to the mezzanine floor and approached Haynes.

"Let me introduce Professor Kennedy, Madame Dupres," presented Haynes.

Kennedy bowed.

Whatever one's opinion of madame, he was forced to admit that she was clever. It was evident, also, that she and Haynes were on very intimate terms, also.

"I hope that you will be able to clear up the mystery that the newspapers have found in Mr. Delaney's death," she remarked. "Mr. Haynes has told me that he met you tonight with Dr. Leslie. By the way, has he told you his own theory?" she asked.

"We shall do our best," replied Kennedy, meeting her eye in as impersonal a manner as it was possible, for it is always difficult to dissociate a beautiful woman from a case like this and judge her not as a beautiful woman but on the merits of the case. "No, Mr. Haynes has not told me his theory—yet."

"I'm very glad to have met you," she added, extending her daintily gloved hand to Kennedy, "and you may be sure that if there is any way in which I can be of service I shall expect you to call on me. Just now I hope you will excuse me. I have some letters to get off—and I will leave you men to discuss Mr. Haynes' theory without being hampered by a mere woman. Never mind, Harris," she added as Haynes made as if to escort her to the ladies' writing room.

As Madame Dupres passed down the steps there was no denying that she made a splendid impression. Haynes watched her with a glance that was almost ravenous. There could be no doubt of her influence over him.
