“Test me again!” said the amused and confident voice of Karl Wertheimer. “Something really difficult this time!”
The old man leaned back in his chair and pondered. Then the gleam of an idea came into his malicious gray eyes.
“Right!” he said, emphatically. “You know the library in my house?”
“Certainly, Excellenz!”
“Go into my library. Read me the fifteenth line of the ninety-first page of the sixth volume on the third shelf of the right-hand side, without opening the book. Can you do that?”
“You shall see, Excellenz,” replied the voice, cheerfully. “The sixth volume counting from the left, I presume?”
“Yes.”
“I will note that,” said Kranz, coming to the table. He wrote the particulars and looked up to his superior. “Do you know what the line is, Excellenz?” he asked.
“I don’t even know what the book is!” replied the old man, harshly. He wrinkled his brows in impatience at the silence, which prolonged itself through several seconds. The girl seemed quite normally asleep.
