"813 . . . 813. . . ." And, in a lower voice, "813 . . . an '8' . . . a '1' . . . a '3' . . . yes, of course. . . . But why? . . . That's not enough. . . ."

The Emperor muttered:

"He impresses me. I find it difficult to believe that a man can play a part like that. . . ."

Ten minutes more . . . five minutes more . . .

"Is the car there, Waldemar? . . . Are your men ready?"

"Yes, Sire."
