“Who is she?”

“I am obliged to confess that I do not know her name,” the doctor admitted, smiling. “I doubt if she knows mine either. We have not stopped to exchange cards in this business; it has been of too serious a nature to admit of much ceremony. I call her ‘madam,’ and she has, naturally, addressed me as ‘doctor.’”

“She seems a thorough lady,” said his patient, thoughtfully.

She had, as Sir William once told her she would, changed her ideas somewhat regarding American people since coming to this country.

“You are right, madam,” replied the physician, emphatically. “It has never been my privilege to meet a more cultured lady nor a truer woman. I shall certainly ask her to favor me with her name and address before she leaves.”

“Is she going away?” demanded Lady Linton, quickly.

“Yes; in a day or two, I believe; her maid is doing nicely now and able to travel. But, bless me, I must not sit chattering here when there are more than forty patients waiting for me.”

And the brisk little doctor trotted off, leaving Lady Linton looking very thoughtful, and wondering who her mysterious but beautiful nurse might be.
