As if by magic, Dr. Hunter was transformed by those words from an object of pity into a very interesting young man. Professionally his life was not altered, but the very next week he was invited to a little dance; and every one who saw him there was irresistibly urged to invite him to something else. Ladies came to call upon Mrs. Carew, to sing the praises of her charming nephew. He was forever going out, or getting ready to go out, and he seemed to be very happy about it.

From the window Mrs. Carew would watch him drive off in his little closed coupé, so useful for a doctor, who must be abroad in all weathers. Much as she admired his resplendent appearance, and rejoiced in his popularity, she did wish that now and then he might be summoned to something less cheerful than a party.

That never happened. The more he was danced with and flirted with, the more did it seem tactless and ill-bred to mention one’s sordid ailments to him. It was unthinkable to call in one’s dancing partner and confess to a bilious headache from too much pastry. No one could see him as a doctor.

He seemed not at all downcast by this. Indeed, Mrs. Carew sometimes imagined that he had forgotten all about being a doctor.

“Don’t you think you ought to read your medical books now and then, Noel?” she suggested. “Just to—to keep up?”

“Oh, no!” he replied cheerfully. “I’m not likely to forget all that stuff that was so much trouble to learn. Don’t worry!”

“But you mustn’t lose interest, Noel,” she persisted.

He flushed a little, for he had at the moment two preoccupations which were nearer to his heart than the theory and practice of medicine. The first of these was Nesta Lorrimer, and the second was her brother’s hydroplane. They merged very well, because Nesta was frequently in the vicinity of the hydroplane, so that they could both be studied together.

It was unfortunate that Noel did not mention this to his aunt, because she would have approved heartily of one of those interests; but he knew that aunts were extremely likely to worry about flying. He was very fond of her, and didn’t want to worry her; so the poor lady knew nothing.

Mrs. Lorrimer knew, however.
