stupidly and Juve found it necessary to explain in a few
words the quest he was setting out upon.

"If our man isn't on the first train that passes Courcelles, then we
must hurry over to the Bois de Boulogne Station, understand?"

* * * * *

Juve had the luck to learn from the ticket seller at Courcelles that she
had noticed Wulf, and that he had bought a first-class ticket; this
limited the search very considerably.

The first train pulled in, but Wulf was not on board.

Juve sprang into his taxi and now hurried over to the Bois de Boulogne.
Here the same result met him; the next station was Auteuil, then
Vaugirard, la Glaciere and Bel-Air.

It was now eight o'clock, and his appointment with M. Annion was at
eleven. What was to be done?

On reaching Menilmontant Station, Juve had about decided to abandon the
chase.

"I'll wait for one more train and then make some other plan," he
muttered.

By great good luck he caught sight of Wulf as it ran into the station.
Rushing into the carriage, he seized his man and hauled him on to the

Juve bustled him into the waiting taxi.

"I'll explain as we go," he replied. "It is a question of saving the
King. He is menaced by powerful and terrible enemies."

"I am ready to die for him," exclaimed Wulf. "What must I do?"

"Oh, it's not necessary to die. All you have to do is to certify before
the police authorities that the person you know as Frederick-Christian
at the Royal Palace is actually the King."

"I don't understand in the least what you mean!"

"That doesn't matter; you have only to do as I say and all will be
well."

M. Annion was overcome.

Wulf, after testifying to the identity of the King, had been sent to
wait in an adjoining room while Juve and M. Annion had a confidential
chat.

"Well, Juve, I can't get over it. Without you, I should have made a
terrible break! The King arrested! What a scandal! But, tell me, what's
to be done now? The public's calling for the m
