"I have known one-lungers to live a long time," he said. "You mentioned Dr. Sinclair a moment ago. Whatever offence did Jessie take at him which led her to treat him so disagreeably?"

Mrs. MacAllister had just finished dressing and arranging her hair, and was taking a last look at herself in the mirror. She closed her lips tightly, threw back her head, and gave a little sniff:

"So you think she was offended at him," she said.

"What else could make her act the way she did last evening?"

"I wish that I could believe that you are right. But I am afraid that you are not."

"What do you mean?"

"I do not believe that she was a bit offended."

"Well, if she wasn't, I cannot see what possessed her to act so badly. She did everything she could to make him uncomfortable. I feel as if I ought to make some explanation of her conduct or offer some apology."

There was another sniff as she answered tartly:

"It would be wiser not to."
