"And until that something is taken off her mind she will never recover," continued the doctor.

"The something is gone now, Dr. Duncan," she said, looking straight into his eyes.

"I hope that is so," he replied doubtfully.

"What a fool the man must be not to understand me," thought Catherine; but the doctor had very good reasons to know that it was not love for Tom Hudson that weighed on the young girl's mind.

"Well! let us go and see Mary now," she said.

The girl had been placed in a small private room by herself. When they came to it the door was opened by the nurse who was in charge of the patient.

Catherine looked keenly at the young woman, then turning to Dr. Duncan, exclaimed:

"I thought you told me the other day that Miss Riley was nursing my niece."

"She has been nursing her," replied the doctor, "but we have sent her away for a holiday. She has been much overworked lately, and is far from well."

"Indeed!" exclaimed Catherine.
