"Great Scott!" exclaimed the detective, with a resounding slap upon his knee, "I'll wager my badge that it's a sequel to that Bently affair, when a young broker of Chicago was wretchedly fooled with some diamonds about three years ago!--that woman also had short, curly red hair." He related the story to Mr. Palmer, and informed him that he had been engaged upon the case, off and on, for a long time; but since he had come to New York to reside he had about given it up as hopeless. "This may put me on the trail again, however," finally remarked Mr. Rider, who was the detective that Justin Cutler had employed. Of course, the house which Mrs. Vanderbeck had given as her place of residence was visited, but as in the Bently affair, it proved to be empty, and Mrs. Vanderbeck seemed to have vanished as completely as if she had been a visitant from some other sphere. All this had occurred while Mona was so absorbed in her grief for her uncle; when she had had no interest in anything outside her home, and so not having read any of the newspapers, she was entirely ignorant of the excitement that had prevailed over the robbery, and Ray's disappearance. Thus she believed that he had deserted her, like most of her other fair-weather friends, and was trying to make herself believe that he was unworthy of her regard. Poor Ray! it had fared hard with him during all this time, although not in the way that his father and the detectives feared. We last saw him just after he had discovered the shred that had been torn from Mrs. Vanderbeck's dress; but when Doctor Huff again went to him he found him prostrate upon the floor in a high fever and delirious. For four weeks he lay thus. He had taken a severe cold, and that, with the excitement and anxiety caused by the loss of the diamonds, had brought on the illness. When Doctor Wesselhoff returned after a hard fight with disease in his wife's case, he found him very low, and just at the turning point in his fever. He bestowed great commendation upon his pupil, however, for his management of the case, which, he said, he could not have treated better himself. He expressed himself as very much surprised, because none of the young man's friends had called to make any inquiries about him; it certainly showed a lack of interest, if not a positive neglect, he thought. He believed that the fever would turn favorably, for the young man had a naturally vigorous constitution, and he had known of persons recovering who had possessed far less vitality. Ray did pass the crisis successfully, but he was very weak for many days longer; too weak even to notice where he was, or who was caring for him.
