"Until two weeks ago Herr Renwick was an attaché of the British Embassy," she asserted.

"Of course. But he has been also in the pay of the Serbian government—Austria's enemy."

"You are misinformed," she gasped.

"I beg your pardon. England and Serbia are on excellent terms. You will not deny that Herr Renwick has been to Belgrade in the last two weeks?"

"You—you——" she paused in consternation, aware again of this man's omniscience.

"The details had not been clear until my return to Vienna. Think for a moment. Herr Renwick visits Belgrade and Sarajevo while a plan is arranged to take the life of the Archduke Franz. It is well within the bounds of possibility——"

"Your skill in invention does you credit," she put in quickly, "but Herr Renwick has no interest in the death of the Archduke. On the contrary, he has done what he could to save him."

"You will admit that it was Renwick who gave you the information of this plot."

"Yes—but——"

"One moment. You'll also admit that he gave no authority for his information."
