"There is no doubt, however, this Grand Duchess Alexandra should be well posted ... now. She has formally promised the King that his diamond will be found in the possession of our man ... who will be under arrest this evening...."

"You believe that?" questioned M. Lepine, with a skeptical smile.

"Well, I believe in the arrest—that is certain; but whether we shall find the diamond is another matter."

Juve's first impulse was to make himself known to his chief; but on second thoughts he decided to keep silent. He had gathered from the conversation that the arrest of Fantômas was imminent. That, of course, was satisfactory in every respect.

The conversation continued and, as he listened, Juve could not help smiling.

"They are all right! They realize the work I've done and they want me to reap the reward of it."

M. Lepine had, in fact, asked M. Annion:

"You are quite sure Juve will be at the Gare du Nord this evening?"

"Quite sure; I have given him orders to that effect."

Juve decided it was not worth while going home to get the order. Evidently they counted upon him to be at the Station at nine o'clock; ostensibly to assist at the departure of the King, in reality to arrest Fantômas.
