ness--her ignorance was abysmal. The stage--she
could count on her fingers the late plays which she had seen.

When the trail had grown almost cold, there happened a little incident
which put him on the scent again. He had thought suddenly of his
patient in the compartment and made a visit, only to find her asleep.
Upon his return he said:

"You behaved like a soldier and a nurse toward her--a girl with such a
distinct _flair_ for the game must have had longings to take up
nursing--or perhaps you never read 'Sister Dora'?"

"I did read 'Sister Dora,'" she answered, "and I was crazy about it."

"Most girls are--hence the high death rate in hospitals," he
interrupted.

"But I gave that up--and a lot of other desires which all girls
have--for something else. I had to." Her sapphirine eyes searched the
Berkshire hills again, "Something bigger and nobler--something which
meant the entire sacrifice of self."

And here the brakeman called "Next station is Berkeley Center." Dr.
Blake came to the sudden realization that they had reached his
destination. She started, too.

"Why, I get off here!" she exclaimed.

"And so do I!" He almost laughed it out.

"That's a coincidence."

Dr. Blake refrained from calling her attention to the general flutter
of the parlor-car and the industry of two porters. This being the
high-tide time of the summer migration, and Berkeley Center being the
popular resort on that line, nearly everyone was getting off. However
as he delivered himself over to the porter, he nodded:

"The climax of a series!"

As they waited, bags in hand, "I am on my way to substitute for a month
at the Hill Sanatorium," he said. "The assistant physician is going on
a vacation--I suppose the ambulance will be waiting."

"And I am going to the Mountain House--it's a little place and more the
house of friends than an inn. If your work permits--"

He interrupted with a boyish laugh.

"Oh, it will!" But he said good-bye at the vestibule with a vague idea
that she might have trouble explaining him to any very particular
friends. He saw her mount an old-fashioned carry-all, saw her turn to
wave a farewell. The carry-all disappeared. He started toward the Hill
ambulance, but he was still thinking, "Now what is the thing which a
girl like _that_ would consider more self-sacrificing than nursing?"
