After fully five minutes had elapsed, the door opened and a tall man looked out.
"It is I, doctor," said Nannie Rogers. "May I step inside? I want to speak to you. I have a patient waiting outside the gate."
"Dear me! is it really you? You come at rather a late hour. Still, you know you are a priviliged person here."
"I ought to be, since I have learned so many secrets about the place and yourself," she said, "when I was nurse here."
"Didn't I give you five hundred dollars to insure secrecy when you left here?"
"Well, I kept my promise. I never told anything, did I?"
"Let me understand what you want," he said, abruptly. "Did I understand you to say that there was a patient outside?"
The girl nodded.
"It does not matter who or what she is," she said, tersely. "It is the desire of her friends that she be kept here for a few months. I suppose you are anxious to know about the pay?"
