O’Hara laughed. “Oh, ho!” he shouted, dropping into a chair, “now we have it. You are mad, and so you cannot go to Budavia to claim your own.”

Johann nodded; and Grey, leaning against the edge of the table, was lost for a moment in thought.

“But the Fraülein?” O’Hara questioned. “What did they say of her? Was she to be left with the madman?”

“No, Herr O’Hara; only for a little. The Herr Captain Lindenwald had arranged, Lutz told me, to have Herr Arndt taken to an asylum by the doctors and then the Fraülein was to be brought to Kürschdorf.”

Grey smiled, grimly. “The doctors were the gentlemen you chased out of the window last night, Jack,” he said. And then he asked of Johann: “Did they say anything of Baron von Einhard?”

“No, Herr Arndt.”

“You are quite sure?”

“I have not heard of his name, Herr Arndt.”

Then Johann was told of the plan of departure and was sent off to telephone for another place on the Orient Express for himself. When he returned the American said to him:

“It was very good of you, Johann, to come back.”
