He had seen her again—nay, more, he had heard her sing—this girl-nightingale, who had taken the world by storm. Chance had favored him, insomuch that he had been able to secure almost a front seat in the concert room, and the wonderful music of her voice rang still in his ears. He had stolen out here to try and think it all over, and to calm the passion which had suddenly leaped up within him. It was quite a new experience through which he was passing; he scarcely knew himself. He was happy and miserable, sanguine and despondent, all in a moment. One question was always before him—one end, one aim. How was he to know her? How could he endure to live here, seeing her day by day for a brief while, without making her acquaintance? There was nothing to be hoped for from the Sicilian, who would not even tell him her name. Possibly, though, she would visit, or be visited by, some of the nobility of the place. This was almost his only hope. He had letters to most of them, and he made up his mind to present them all on the morrow.

He sat there dreaming, with a burned-out cigar between his teeth, and his eyes idly wandering over the blue Mediterranean. Suddenly the stillness was broken by the sound of a soft gliding footstep close at hand. He had heard no one approach, yet when he looked up quickly he found he was no longer alone. A man in the garb of a native peasant was standing by his side.

Naturally the Englishman was a little surprised. He half rose from his seat, and then resumed it as he recognized the dark, swarthy face and black eyes of the waiter who had told him Adrienne Cartuccio's name.

"Hullo! What are you doing here?" he demanded.

"I was in search of the Signor!" was the hasty response. "For an hour I have sought him everywhere, and now it is by chance that I am successful."

The Englishman looked at him with suspicion. This change of dress was doubtless for the purpose of disguise. What was the meaning of it?

"Well, and now you've found me, what do you want?" he asked, watching him closely.

"I will tell the Signor. Is it not that he has an admiration for Mademoiselle Cartuccio, the singer? Well, she is in danger! It is for the Signor to rescue her."

The Englishman sprang up with sparkling eyes, and pitched his dead cigar into the sea.

"In danger!" he repeated breathlessly. "Quick! Tell me where!"
