“Never say I haven’t done you a good turn,” grinned the Prussian. “A pleasant journey, though it may be a slow one. Don’t be surprised if I am in Aachen before you.”

Then he coloured. He had said too much. One of the men in the compartment gave him a sharp glance. Aachen, better known to travelling Britons as Aix-la-Chapelle, lay on the road to Belgium, not to France.

“Well, to our next meeting!” he went on boisterously. “Run across to Paris during the occupation.”

“Good-bye! And accept my very grateful thanks,” said Dalroy, and the train started.

“I cannot tell you how much obliged I am,” said a sweet voice as he settled down into his seat. “Please, may I pay you now for the ticket which you supplied so miraculously?”

“No miracle, but a piece of rare good-luck,” he said. “One of the attachés at our Embassy arranged to travel to England to-night, or I would never have got away, even with the support of the State Councillor who requested Lieutenant von Halwig to befriend me. Then, at the last moment, Fane couldn’t come. I meant asking Von Halwig to send a messenger to the Embassy with the spare ticket.”

“So you will forward the money to Mr. Fane with my compliments,” said the girl, opening her purse.

Dalroy agreed. There was no other way out of the difficulty. Incidentally, he could not help noticing that the lady was well supplied with gold and notes.

As they were fellow-travellers by force of circumstances, Dalroy took a card from the pocket-book in which he was securing a one-hundred-mark note.
