“I want you, Tonini, to put yourself at once at your ease,” the Englishman said. “First, there is nothing against you, not the slightest breath of suspicion. His Excellency the Minister has told me that you have been an excellent soldier. You fought in Tripoli with distinction, as your medal shows, and you have, I see, the medal for saving life. But I want you to be perfectly frank with me—to help me, as His Majesty wishes you to do.”

“Has His Majesty been told that I was on sentry duty?” asked the corporal.

“Yes, it has been reported to him, and you, as a loyal soldier of your Sovereign, must assist in every way to help me to clear up this mystery. You know the value of those documents, I presume?”

“Yes. They are plans of our new fortresses against Austria,” replied the man in a changed voice, for Hubert’s words had greatly impressed him.

“Then you know it must be a spy of Austria who has stolen them?” Waldron said. “Either a spy in person, or an individual who has sold them to a spy. Which, we do not yet know. Now you were on duty outside His Excellency’s private cabinet, were you not?”

Si, signore. From noon till four o’clock.”

“The Council of Defence met at noon—just at the time you went on duty. Now tell me exactly who entered or left His Excellency’s room.”

“I will tell you, signore, exactly. I have nothing whatever to conceal,” replied the soldier frankly.

“Of course you have not. If you tell me everything you will greatly assist me in my inquiries.”

“Well, signore, His Excellency came out of the room just as I went on sentry duty, and for half an hour no one else entered. Several clerks and others came to the door, but I did not permit them to go in, and told them His Excellency was absent. At half-past twelve Colonel Pironti, whom I knew as His Excellency’s secretary, came up the stairs, and of course I allowed him to pass in. He was there about ten minutes, when he came out again with a large orange-coloured portfolio in his hand.”
