"No. She locks her door. And I am sure she suffers, for sometimes when I have gone up hoping to help I have heard such strange sounds, as if she were delirious. It frightens me!"

"Does she talk of her illness?"

"Never, and she is furious if I do. She says she is quite well and indeed no one would think that anything serious was wrong unless they lived in the house. Any one outside would be sure that I am worrying needlessly. Am I, do you think?"

"I can't think until I know more. But from what you tell me, it looks as if this medicine she is taking might have something to do with it. If it does no good, it probably does harm. Perhaps it was never intended to be used as she is using it. Otherwise, as you say, the attacks would diminish. At the same time a blind faith in a certain medicine is not at all uncommon. One meets it constantly. Also the prejudice against consulting a physician. It is probable that Mrs. Coombe does not realise that she is steadily growing worse. Could you let me examine the medicine?"

Esther hesitated.

"It is kept locked up. But, I might manage it. If I asked her for it she would certainly refuse. I—I should hate to steal it," miserably.

"I see. Well, try asking first. It is just a question of how far one has the right to interfere with another's deliberately chosen course of action. The medicine is probably injurious, even dangerous. I should warn her, at least. If she will do nothing and you still feel responsible I should say that you have a moral right to have your own mind reassured upon the matter."

Esther smiled. "I believe I feel reassured already. Perhaps I have been foolishly apprehensive and it never occurred to me that the medicine might be at fault; at the worst I thought it might be useless, not harmful. If I could only manage to have you see it without taking it! There must be a way. I'll think of something and let you know."

"Do." The doctor picked up his hat for the second time. He was genuinely interested. He had not expected to find a problem of any complexity in sleepy Coombe. The cases of Aunt Amy and the peculiar Mrs. Coombe seemed to justify his staying on. It was pleasant also to help this charming young girl—although that, naturally, was a secondary consideration!

Esther ran upstairs with a lightened heart.
