The Baron nodded.
"Careful of your Leugger," he whispered, "the soldiers will see it. You can shoot me just as easily if you keep it hidden. I have frequently fired through my pocket."
In a hotel room a half-hour later, Mathilde, grown jubilant as a child, was clapping her hands and laughing.
"It was too simple!" she cried.
Dorn drew a small suitcase from under the bed and opened it.
"Here it is," he laughed. He removed an oblong package. His eyes sought von Stinnes, standing near the window leisurely smoking a cigarette.
"You will find Levine in the Gambrinus Keller," von Stinnes spoke without turning around. "I advise you to go at once, Matty, before the streets crowd up."
He wheeled and held an envelope toward the girl.
"Take this. It will make it easier for you to get in. They are very careful right now. It's a letter of credentials from Dr. Kasnilov."
Mathilde opened the envelope mechanically, her eyes seeking the thought under the Baron's smile.
