"It is my authority signed by Count von Gratzen; you can just make out a part of the official seal; and you will have seen that Herr von Welten was on the platform when we left Berlin."

"Yes, sir. He gave me orders to reserve this compartment for you, but——"

"You can't do anything, I know; but I wish you to make a note that I told you of the loss. That's all."

"Would you telegraph to his Excellency, sir?"

"Where's the first stop?"

"Not till Hanover, sir; but as it is State business and so important, I could stop at the next station for you to send a message, and you would have a reply wired to Hanover, or Osnabrück, if you are going so far."

"A good idea, guard. I'm much obliged to you. I'll think about it; just give me a form." He took one from his pocket and went off, saying he would come back for the message.

Nessa had listened in the greatest amazement. "Who on earth am I travelling with?" she cried. "Do you mean that you are able to have trains stopped at your mere nod?"

"I'll tell you who you're travelling with in a moment, but let me think whether I dare send that wire." It wasn't long before I decided to risk it. Von Gratzen himself had suggested I should get out of the way for a time: even go to a distance: and would understand the importance of the ruined authority, since I could not return when he needed me without it. He would therefore wire me all I should require, pending the receipt of a new authority. That was all clear enough.

But there was a fly in the ointment. He might have discovered the theft of the papers. But even in that case there wasn't very much risk, as the von Erstein affair was so vastly more important that he would hesitate before sending any instructions to get me into trouble. So I wrote the message and gave it to the guard, with a ten-mark tip, and the train was accordingly stopped for it to be despatched.
