The Ear in the Wall

by Arthur B. Reeve

"So you see," he concluded, "this is without any doubt the woman we saw at the Futurist, whom Miss Kendall followed to Madame Margot's Beauty Shop, two doors down."

Kennedy handed a copy to Miss Kendall.

"Using that and whatever other means you may have, Miss Kendall," he said, "I wish that you would try to find this woman and all you can about her. Walter, take this other copy and see Carton. I think he has a county detective who knows the system. I shall spend the rest of the day getting in touch with the Federal authorities in this city and in Washington trying to find out whether they know anything about her."

We left the Montmartre with as much care as we had entered and seemingly without having yet aroused any suspicion. The rest of the day was spent in setting to work those whom we felt we could trust to use the portrait parle to locate the mysterious dark-haired Marie who seemed to cross our trail at every turn, yet who proved so elusive.

THE CONVICTION

Meanwhile, the organization was using every effort to get possession of the Black Book, as Kennedy had suspected.

Miss Ashton had been busy on the case of the missing Betty Blackwell, but as yet there was no report from any of the agencies which she had set in motion to locate the girl. She had seen Langhorne, and, although she did not say much about the result of the interview, I felt sure that it had resulted in a further estrangement between them, perhaps a suspicion on the part of Langhorne that Carton had been responsible for it.

In as tactful a way as possible, Miss Ashton had also warned Mrs. Ogleby of the danger she ran, but, as I had already supposed, the warning had been unnecessary. The rumours about the detectaphone record of the dinner had been quite enough. As for the dinner itself, what happened, and who were present, it remained still a mystery, perhaps only to be explained when at last we managed to locate the book.

Since the visit of Kahn, we had had no direct or indirect communications with either Dorgan or Murtha. They were, however, far from inactive, and I felt that their very secrecy, which had always been the strong card of the organization, boded no good. Although both Carton and Kennedy were straining every nerve to make progress in the case, there was indeed very little to report, either the next day or for some time after the episode which had placed Kahn in our power.
