elf." Why, she had not told him where the pension was! Never
mind, perhaps he was sorry for his behaviour to her; she would give him
the benefit of the doubt. It was surely unlike him to be so gracious.
She shook her head over the puzzle he presented.

Her packing done, she put on the coat of her costume over her marron
crepe-de-Chine jumper--the one she had bought in the Croisette--and
going to the mirror adjusted her little felt hat carefully. She
recalled the fact that, except for the blouse, these were the same
clothes she had worn that day she first called to interview the doctor,
and later had gone on for tea at the Ambassadeurs. How long ago it
seemed! The costume and hat looked as new and smart as ever, she had a
