"Reach London with all speed. Will you come, Lieutenant?"

De Loubersac considered.

"No," he decided.... "In the first place, I have no right to leave the country unless authorised to do so. I am not free to act according to my own good will and pleasure: besides, I have an idea there is work for me in Paris.... To watch that little intriguer, Bobinette, will be an interesting task: from what you told me yesterday, she is up to the neck in those villainous plots and plans! While you investigate in London, Paris shall be my field of operations. You approve of this, Juve?"

"I think you are right."

Juve accompanied the lieutenant to the station: de Loubersac was in a hurry to be off. He would not wait for the noon express: he took the slow train. As it began to move, he and Juve exchanged a cordial handshake.

"Good luck!" cried he.

"Thanks, Lieutenant. Good courage!"

The latter admonition was given with a purpose; for Juve was under no illusion as to de Loubersac's feelings.

"At any other time," thought he, "de Loubersac would have seen it to be his duty to accompany me to London: he could have secured an authorisation from his headquarters if required; besides, attached to the Second Bureau as he is, no doubt the ordinary military rules and regulations would hardly apply to him: to a large extent he must be allowed a free hand in emergencies. This is an emergency—an important one!... No, he wishes to see Wilhelmine: he is in love, is worried, suspicious: he wishes to clear up the mystery surrounding Wilhelmine's identity: he is determined to know what exactly were her relations with Captain Brocq: also, he wants to find out all there is to find regarding Bobinette and her doings.... To get to the bottom of these dark mysteries, unravel the tangled threads needs a clear head and a brave heart, for his feelings are deeply involved, and they may yet be cut to the quick!... He is a straight goer, that young man!" was Juve's concluding thought.... "He will do his duty: and when one does one's duty, with rare exceptions, the result is happiness."
