It looked as if the younger man, while really uncomfortable, were trying to act as if he were not afraid of her.

"Is there not such a thing as the Oriental Express?" he asked. "Had you used that, we might have met at Turin, and have saved a great deal of trouble and valuable time."

The lady turned impatiently from him to his companion.

"What form does your news take?" she enquired. "Is it contained in a letter?"

"No, Excellenza, it was to be delivered by word of mouth," the other replied. "The Council, who were in Prague at the time, paid me the compliment of trusting to my discretion, and despatched me immediately to you. We heard that you were in Constantinople, and the Secretary undertook to have a message transmitted to you there. Our friend, Conrad here, is perhaps not aware that the Oriental Express is occasionally an impossible medium. But, while condoling with you on that score, I must congratulate your Excellency in having pressed the Duke of Rotherhithe into your service."

"Pray spare yourself the trouble," the lady replied. "I do not know that I am particularly fond of obtaining hospitality, such as his, under false pretences. It is sufficient for your purposes, is it not, that I am here, and ready to do the Council's bidding, whatever that may be. Perhaps you will be good enough to tell me what is expected of me?"

"Is it safe for me to tell you here?" Luigi enquired, and as he said it he looked anxiously about him, as if he feared the presence of eavesdroppers.

"As safe as it will be anywhere," the lady answered. "It is an Englishman's yacht, and, whatever we may say of them, they are not in the habit of listening at keyholes. Now what have you to tell me?"

The man hesitated once more before he replied. He was the chosen mouth-piece of one of the most powerful organisations in Europe, and ere now affairs involving death, and worse than death, had been entrusted to him, and he had brought them to a satisfactory issue. As a rule, and certainly when dealing with men, he did not know what fear was. In this lady's presence, however, he was strangely nervous.

"Come," she said, "you are a long time telling me. Is it so very difficult to explain? Or am I to anticipate a repetition of the Palermo Incident?"
