“You threaten me—eh? You?”

“I do not threaten,” Hubert hastened to assure him. “I shall only act in case you should act against the interests of Her Royal Highness.”

“I do not think you, a foreigner, can interfere very much with my interests,” laughed the other in defiance.

“Think whatever you please. After you have had audience with His Majesty I, too, shall have audience, and when I have left, then the King will probably tell you what I have revealed to him.”

“And what, pray, can you reveal?” asked the Chief of the Secret Service, his grey brows again knit, showing that he was somewhat puzzled by the diplomat’s defiant attitude.

“That is my own affair,” replied Hubert with a triumphant smile. “Suffice it to say that the hour you make any statement concerning what you have witnessed to-night, then in the same hour you will cease to be Chief of Italy’s Secret Service!”

“Do you think to frighten me, then?”

“I have no wish, my dear Signor Ghelardi,” was Hubert’s very polite reply. “I only desire that no further scandal should be attached to Her Royal Highness’s good name.” And after a brief pause he looked the official straight in the face and said: “I offer you silence for silence!”

“And I decline your most generous offer.”

“Good. Then we shall see!”
