to argue--she had simply gone out.

Well, it was something to feel that she, Esther, had done what she
could. At any rate, there was no time to worry, for the doctor was
already coming up the walk.

Esther hurried to the door. It relieved her to find that he seemed to
expect her, and showed no offence on realising that the patient's
nearest relative was not at home to receive him. Indeed, he seemed to
think of no one save the patient herself. His manner, Esther thought,
was perfect. Had she been a little older she might have suspected such
perfection, deducing from it that Callandar, like herself, was
subconsciously aware of an interest in the situation not altogether
professional. But the girl made no deductions and certainly there was no
trace of any embarrassment in the doctor's way with his patient. It took
only a moment for Esther to decide that here, at least, she had done the
right thing. She waited only long enough to see the frightened look in
Aunt Amy's eyes replaced by one of timid confidence and then, murmuring
an excuse, slipped away, leaving them together.

Callandar also waited while the startled eyes grew quiet and then lifted
the fluttering hand into his own firm one.

"Creatures of habit, we doctors, aren't we?" he said, smiling. "Always
taking people's temperatures."

Aunt Amy ventured upon a vague answering smile.

"I understand," continued the doctor, "that you have reason to fear that
you have been poisoned?"
