"I am your superior officer!" countered von Kuhne. "It is, fortunately, my privilege to speak plain words to you; it is equally my privilege to command your obedience. You have failed in regard to this young man, Bernard Treves. From the first hour of his contact with Manwitz he has clearly tricked you both!"

"May I venture to remind you, Excellenz, that he tricked you also?"

Von Kuhne lifted his fierce and truculent gaze.

Cherriton was neither intimidated nor silenced.

"He tricked you, Herr Excellenz, the day of his first visit here. You announced to me then that you were satisfied. You observed upon his wrists the punctured marks which proved him, as you said, Excellenz, to be addicted to the injection of drugs."

Von Kuhne waved these objections aside.

"I based my opinion upon his dossier provided for me by you and Manwitz." He began to pace the floor, with his hands behind his back, his head thrust forward in deep thought. "This affair, Rathenau," he said at length, "this discovery grows more and more sinister. It is clear to anyone not utterly a fool that every step of yours and Manwitz has been dogged for many weeks past. What this young man knows of our plans we shall never learn; what he has confided to his authorities we can only guess. One thing, however, is certain: whether he knows much or little, his activities must cease." He paused and looked full into the younger man's face. "Do you gather my meaning?"

Cherriton bowed.

"I understand, Excellenz."

Von Kuhne continued to pace the carpet.
