I think she must have guessed to what I referred, for her face flushed a little, and she hastily diverted the conversation into another channel, by drawing my attention to a picturesque sailing-boat which at that moment was entering the harbour. I tried to entice her back to the subject later, but she would plainly have none of it. Only once did she refer to it, and that was when we were making our way back to the hotel to lunch. I stated my fear lest she should find all this running about from place to place tiring for her.

"You need not be afraid of that," she answered. "I am very strong, and am not easily tired. Besides, you have been so good and kind, Mr. Fairfax, and have done so much to ensure my comfort, that, if only out of gratitude to you, I could not very well be fatigued. I think you know how grateful I am to you, do you not?"

As she said this she looked up at me with her beautiful trusting eyes, and so overwhelmed me that it was as much as I could do to keep back the words that rose to the tip of my tongue. I answered her to the effect that I had only done my best to promote her comfort, and was about to say something further, when Leglosse made his appearance before us. There was a look of great satisfaction upon his face.

"I think I know now all that there is to know," he said. "If mademoiselle will excuse me, I will tell it. Monsieur Hayle arrived here some five days ago, and has taken possession of a charming villa some ten miles from the city. It is situated on the coast and the agent declares it to be unique. How long he intends to occupy it, he, the agent, could not say, but he has paid a high rent for it in advance, which appears to have given unlimited satisfaction. The other two men are still prowling about the city in search of him, but so far they have not been successful in their endeavours."

"Could I not go to my uncle?" Miss Kitwater inquired. "It might be possible for me to persuade him to leave the island without seeing this wretched man."

"I fear it would be useless," I answered. "And you would only cause yourself unnecessary pain. No! what we must do is to communicate with the Palermo police: Leglosse can show them his warrant, and then we must endeavour to get Hayle under lock and key, and then out of the island, without waste of time. That is the best course, believe me."

"If all goes well, I shall make the arrest to-night," said Leglosse, and then added, "I must get back to Paris as soon as possible."

That afternoon he went out once more, this time to interview the police authorities. At five o'clock he returned in a state of great excitement.

"The other two have discovered Hayle's whereabouts," he said, when we were alone together. "And they have set off in pursuit. They have been gone more than an hour, and, unless we start at once, we shall be too late to take him before they run him to earth."

"Good Heavens! Are you quite sure of this?"
