The stillness that ensued was intense and portentous. The glance that passed between Voules and Cherriton was one of infinite meaning. Voules's expression of ferocity moderated; he turned his eyes again to the intimidated Conrad standing in the doorway.

"How long has Mr. Treves been here?"

"A few minutes only, Herr Excellenz. He came in after Herr Manwitz."

"Very good, Conrad! You will take particular care Mr. Treves does not leave the house, and you will in the meantime send Herr Manwitz to me."

"Very good, Excellenz."

"You understand my order in regard to Herr Treves?"

"Yes, Excellenz. He is not to leave the house."

General von Kuhne nodded and turned on his heel. As the door closed upon Conrad, his implacable eyes once more sought Cherriton.

"The letter you hold," he began, making a stiff gesture towards Mrs. Beecher Monmouth's missive, which Cherriton was still studying—"the letter you hold in your hand convicts this man completely. His treachery to us, his espionage"—he paused a moment—"may bring upon us the utmost disaster. In failing to discover his duplicity you have shown yourself no less than a sheep-headed fool!"

"Herr Excellenz!" protested Baron von Rathenau, drawing himself up, a flush of colour animating his dull pallor.
