"Is Mr. St. George in his apartments?" asked the scientist of the elevator boy.

"No, sir," said the boy. "He's in hospital, shot."

"Is there a key to his place? Quick."

"I think so, sir, but I can't give it to you."

"Here, give it to me, then!" exclaimed the detective. He flashed a badge in the boy's eyes, and the youth immediately lost a deal of his coolness.

"Gee, a detective! Yes, sir."

"How many rooms has Mr. St. George?" asked the scientist.

"Three and a bath," the boy responded.

"Dear me, dear me!" he exclaimed.
