"I didn't even know that he was out, Joseph. Who wants him?"

"A gentleman, ma'am, who says he comes from Munich."

CHAPTER VII

On further inquiry, it turned out that "the gentleman from Munich" had no time to spare. In the absence of Mr. Keller, he had asked if he could see "one of the other partners." This seemed to imply that commercial interests were in some way connected with the stranger's visit—in which case, Mrs. Wagner was perfectly competent to hear what he had to say.

"Where is the gentleman?" she asked.

"In the drawing-room," Joseph answered.

Mrs. Wagner at once left the office. She found herself in the presence of a dignified elderly gentleman, dressed entirely in black, and having the ribbon of some order of merit attached to the buttonhole of his long frock-coat. His eyes opened wide in surprise, behind his gold spectacles, when he found himself face to face with a lady. "I fear there is some mistake," he said, in the smoothest of voices, and with the politest of bows; "I asked to see one of the partners."

Mrs. Wagner added largely to his amazement, by informing him of the position that she held in the firm. "If you come on a matter of business," she proceeded, "you may trust me to understand you, sir, though I am only a woman. If your visit relates to private affairs, I beg to suggest that you should write to Mr. Keller—I will take care that he receives your letter the moment he returns."

"There is not the least necessity for my troubling you," the stranger replied. "I am a physician; and I have been summoned to Frankfort to consult with my colleagues here, on a serious case of illness. Mr. Keller's sister is one of my patients in Munich. I thought I would take the present opportunity of speaking to him about the state of her health."
