"She sings," said Miss Blagden, with a slight smile.

"Yes, the Count was with her."

"Humph! where did they sit?"

"In the upper part of the house somewhere. I felt myself out of place among the Four Hundred. But it brought me luck."

"How is that?"

"I secured a patient, a Mr. Gregory Vincent of Madison Avenue."

"Was Gregory Vincent there? How did you make his acquaintance?"

"He was my next neighbor. He seemed to take a liking to me, confided to me that he was a victim of rheumatism, and I am to assume charge of his case."

"I am very glad," said Miss Blagden, heartily. "Do your best to cure him."
