“This young lady asked about the Green Room,” said the clerk significantly.

Mr. Fergus bestowed a shrewd, appraising look upon Penny.

“Oh, yes,” he said to give himself more time, “Oh, yes, I see. What was it you wished to know?”

“How does one obtain a card of admission?”

“It is very simple. That is, if you have the proper recommendations and bank credit.”

“Recommendations?” Penny asked blankly. “Just what is the Green Room anyway?”

Ralph Fergus and the clerk exchanged a quick glance which was not lost upon the girl.

“I see you are not familiar with the little service which is offered hotel guests,” Mr. Fergus said suavely. “I shall be most happy to explain it to you at some later time when I am not quite so busy.”

He bowed and went hurriedly back into the office.

“I guess I shouldn’t have inquired about the Green Room,” Penny observed aloud. “There seems to be a deep mystery connected with it.”
