"Now, both ladies deny that they knew the deceased, and perhaps they are right. It is, of course, possible that there was a third man in the building that evening, who was also tall, dark, and wore a pointed beard. It is not likely, however. Such a coincidence is almost unheard of. Still it is possible, and that possibility must be reckoned with. Now, I must be off," said Mr. Merritt, rising abruptly from his chair, "and if you hear any more of the young lady's movements, let me know. There's my address. In the meantime, thank you very much for what you have already told me." And before I could get out one of the twenty questions that were still burning on my lips, the man was gone. For some minutes I sat quite still, too miserable to think connectedly. Alas! my fears had not been groundless. The poor girl was in even greater trouble than I had supposed. I believed the detective to be a decent chap, who would keep his mouth shut, but how dreadful to think that her reputation depended on the discretion of any man. Should it become known that she had received one young man alone in an empty apartment, while another was seen there at three o'clock in the morning, it would mean social death to her. Oh, for the right to offer her my protection, my services! Of course, it was now absolutely necessary to trace the man who spent Tuesday evening with her, and to prove beyond doubt that he was still alive. I wished that this might be done without her knowledge, so as to spare her the shock of finding herself suspected of a crime. Again I thought of Fred, and at once sent him a few lines, begging him to let me know whether he or his sister knew of any friend or admirer of Miss Derwent who resembled the enclosed description, and if either of them did know of such a person, please to telegraph me the man's name, and, if possible, his address. While giving no reasons for my questions, I again enjoined the greatest secrecy. CHAPTER VIII AN IDENTIFICATION TELEGRAM. DR. CHARLES FORTESCUE, Madison Avenue, New York City. SATURDAY, August 12.
