“No,” laughed the Englishman; “this is not quite so serious, for though it was actually stolen last night I already have it safe in my possession.”

“You!”

“Yes. I recovered it. But first please tell me to what the tracing refers.”

“Why, to the plans of our new fortresses along the Austrian frontier,” was his prompt reply. “I doubt if they would be understood without that key. Pironti declares they would be valueless.”

“Then the same person who stole the key would have stolen the original plans—eh?”

“Without a doubt. Who was the thief? You know, signore! I can tell it from your face.”

“True, I do know, but at present Your Excellency must excuse me if I remain silent. I hope in His Majesty’s interest—indeed in the interest of the Italian nation to be able to avoid a scandal.”

“But surely you can tell me in confidence. Signor Waldron,” the General protested. “The plans disappeared and I know from my own personal observations that His Majesty held me in suspicion, as responsible for their safe keeping.”

“No suspicion can further attach to you, General Cataldi,” the Englishman assured him, “nor to your secretary. But I have called to ascertain exactly the nature of the key plans.”

“I am much relieved if suspicion has been lifted from my shoulders, signore,” was the General’s reply. “I know that both you and our friend, the Commendatore Ghelardi suspected that someone in the Ministry had connived at this act of espionage.”
