"May I walk back with you to your hotel?" he asked. "Unless this gentleman——"

"Thank you," the girl said, in tones which the Frenchman could have easily overheard had he been listening. "I am quite able to go alone now; it is only a step."

She was still regarding the Frenchman closely; but as he was obviously unconscious of them she moved so that Gordon hid her from him, and in an entirely different voice she said, speaking rapidly,—

"You are Mr. Gordon, the American who joined us last night. That man is a spy from Messina. He is Renauld, the Commander-in-Chief of their army. He must be gotten away from here at once. It is a matter for a man to attend to. Will you do it?"

"How do you know this?" Gordon asked. "How do you know he is General Renauld? I want to be certain."

The girl tossed her head impatiently.

"He was pointed out to me at Messina. I saw him there in command at a review. He has just spoken to me—that was what frightened me into that fainting-spell. I didn't think I was so weak," she said, shaking her head. "He offered me a bribe to inform him of our plans. I tell you he is a spy."

"That's all right," said Gordon, reassuringly; "you go back to the hotel now and send those guards here on a run. I'll make a charge against him and have him locked up until after we sail to-night. Hurry, please; I'll stay here."

Gordon felt a pleasurable glow of excitement. It was his nature to throw himself into everything he did and to at once become a partisan. It was a quality which made his writings attractive to the reader, and an object of concern to his editor. At the very word "spy," and at this first hint of opposition to the cause in which he had but just enlisted, he thrilled as though it had always been his own, and he regarded the Frenchman with a personal dislike as sudden as it was unfounded.

The Frenchman had turned and was walking in the direction of the city gate. His eyes were bent on the sandy beach which stretched before him, and he made his way utterly unmindful of the waves that stole up to his feet and left little pools of water in his path. Gordon beckoned impatiently to the two soldiers who came running toward him at the hotel, and moved forward to meet them the sooner. He took one of them by the wrist and pointed with his other hand at the retreating figure of the Frenchman.
