“You defy me then?”

“Yes, I defy you, signore,” he replied firmly, his dark eyes fixed upon those of the crafty official.

“You are Her Highness’s lover. When the King is made aware of that fact he will show you little graciousness, I assure you,” said Ghelardi with a dry laugh.

“But you will remain silent upon that point, just as you will remain silent regarding what we have discovered to-night,” the Englishman said slowly. “No scandal must attach to the Princess’s name, remember.”

“Of course you wish to shield her—for your own ends. She is the spy for whom we have been searching all these weeks. It is she who placed in the hands of the our enemies the truth concerning the new fortifications along the northern frontier.”

“I refuse to discuss that point,” replied Hubert very coldly, but firmly. “One thing alone I demand of you, and that is silence—silence most absolute and profound.”

“It is my duty to inform the King of the whole circumstances.”

“True, it may be your duty, but it is one that you will not perform, Signor Ghelardi. Think of the terrible scandal throughout Europe if the Press got wind of it! And they must do—if you report officially, and it comes to the ears of His Excellency the Minister. The latter hates the Princess, because she accidentally snubbed the Countess Cioni at the ball at the Palazzo Ginori last week.”

“That is no affair of mine. Women’s jealousies do not concern me in the least. I am charged with the safety of the State against foreign espionage.”

“Well—in this case you’ve discovered the truth accidentally,” responded the diplomat, “and having done so, if you respect your Sovereign and his family, you will say nothing. Further, we may, if we remain silent, be able to obtain more information from Her Highness as to the identity of the person into whose hands the plans fell.”
