Her eyes ask the question anxiously.

This tall, aristocratic, perfectly-appointed man; this man who looks positively _young_.

Where are the glasses that until now hid his eyes?

"Yes." Yes, the professor certainly and as disagreeable as possible.

His eyes are still aflame; but Perpetua is not afraid of him.

She is angry with him, in a measure, but not afraid.
