The look that I gave Mrs. Jack quieted her restless tongue. But the fat was in the fire.

"Yes, the murder's out, Dr. Woodruff," I confessed, wearily. "We've been talking about my husband. We were very happy together before his seizure. And--and--now----"

"And now his wife isn't one, two, three," cried Mrs. Jack, excitedly; "and it's a burning shame. Can you do something for him, doctor? Surely you don't think it's chronic, do you?"

The suspicion of a smile crossed the physician's face, and I felt the blood come into my cheeks. I had no intention of laying my marital misery before the keen eyes of this strangely powerful man, but somehow I felt a sense of relief now that he had come into possession of all the facts.

"If you think it advisable, doctor, for you to hear my husband play," I said, presently, "I'm sure it can be arranged. He has agreed to give a recital at the rooms of the Chopin Society to-morrow evening. He has asked us to go with him. Could you not obtain a card? He would not know, of course, why you were there."

"I have many friends among the Chopin idolaters; it is easily arranged," remarked Dr. Woodruff, as he rose and ushered us toward the exit from his inner office. "Meanwhile, madam, I shall make a close study of the case from the data already at hand. I am very grateful to you for coming to me, and I think I can safely promise to be of service to you. Au revoir. To-morrow evening at eight."

As we seated ourselves in the carriage, I turned angrily to Mrs. Jack. "Why did you betray me?" I cried. "It was cruel, cruel!"

Mrs. Jack smiled affectionately and seized my hand. "Don't be annoyed at me, my dear. I was merely doing justice to Dr. Woodruff. It's absurd to try to put a thoroughbred over the water jump with blinders. It's unfair to the horse, to say the least."
