"Oh, I don't know," he replied; "I've noticed it on lots of occasions. Do you remember the day that plausible Greek beggar worried us so in Constantinople, and you whispered something to him that sent him off about his business like a shot out of a gun. And in Algiers, when that Frenchman made himself so objectionable and you managed to send him to the right-about after a few moments' conversation. How you did it I never could understand, but it was jolly clever all the same."

The Countess regarded him attentively for a moment. Was he really as innocent as he made out to be, or had he noticed anything else? No; one moment's examination was sufficient to convince her that, so far as he was concerned, all was as it should be. Strolling to the port side of the bridge, she looked down at the boat-load of musicians who were strumming guitars, and bawling "Finiculi Finicula," with all the strength of their Southern lungs.

"What a way in which to spend one's life," said the Duke, as he joined her, and tossed some silver into the boat. "Fancy shouting that wretched thing, week after week, and year after year! Italy is a funny country—all bandits, soldiers, beggars and musicians. I suppose, if the truth were known, each of those men belongs to some secret society or another. Either the Cammoristi, or the Mafia, or some such organisation. How would you like to be a conspirator, Countess, and be always in terror of being caught?"

The Countess's hand clenched the bar before her, and, for a moment, her face turned deathly pale.

"What an extraordinary question to ask," she began, fighting hard for her self-possession. "Do you want to frighten me out of my wits? I am afraid I should make the poorest conspirator imaginable. I should be too deficient in courage."

"I am not inclined to believe that," said the Duke, reflectively. "I think you would have plenty of courage when it was required."

"I am afraid you must think me an altogether remarkable person," she returned. "If you go on in this way, I shall scarcely have presence of mind enough to remain in your company. Seriously, however, Duke, I don't know how to thank you for the services you have rendered my father and myself. But for your assistance we should not be in Naples now, in which case we should have been too late to have joined the party with whom I am proceeding to England."

"You are going to England then after all?" he cried in great astonishment and delight. "I thought you were only going as far as Rome?"

"That was our original intention," she replied. "However, some letters that we received to-night have altered our plans. But why do you look so astonished? Are we poor foreigners not to be allowed to enter your country?"
