"No, Your Highness. I only know madame gave orders to admit no one to-night except a gentleman who would come at nine."
I nodded. "It's the same," said I. "And what I want, is to hear all that occurs between Madame Dalberg and this visitor."
Gerst smiled. "That will be easily arranged, Your Highness—the place is already provided."
"The concealed Gallery?" asked Bernheim, quickly?
"Yes, Colonel." Then, to me, he explained: "Madame's reception room was once a part of a small, state dining-room. Back of the end wall runs a gallery where guests sat to listen to the speeches. It is there, now—and the tapestries, with which the walls are hung, completely hide it."
"It can be reached from the floor above?" I asked.
"Yes, Your Highness; a narrow stairway admits to it."
"Can we enter without being overheard by those in the room below?"
"Very readily, sir; the gallery was so designed that its noises would not disturb those in the dining-room."
"We are in good luck, Bernheim," I said.
