Shortly after one o'clock the train reached Rome and they alighted from it. Such travellers as had witnessed the arrival of the invalid at the Neapolitan railway station, would have observed now that he seemed greatly fatigued by the journey. He was even more muffled up than before, while the nurse was, if possible, more assiduous in her attentions than she had been at the southern station. It was noticeable also that she was a poor Italian scholar. Indeed, her pronunciation of such words as she _did_ know was of the most erratic and elementary description. * * * * * Later in the day, just as dusk was falling, an artist's model, in the picturesque dress of the country, might have been observed making her way slowly down the Via Sistina in the direction of the Piazza S. Trinita de' Monti. She appeared to be familiar with the neighbourhood, though, on the other hand, no one seemed to have any acquaintance with her. She had reached the Casa Zuccheri, when she was stopped by a tall artistic-looking man, who walked with great uprightness, and carried a portfolio beneath his arm. For the benefit of the passers by, he enquired in broken Italian, whether the girl could inform him as to the locality of a certain artist's studio, whereupon she personally offered to conduct him to it. He thanked her courteously, and proceeded with her in the direction indicated. They had no sooner left the vicinity of the Via Sistina, however, than he turned to her and said, in the purest Italian: "I was afraid you were not coming. You are very late." "I am aware of that," the girl replied. "I had a suspicion that I was being watched. Now, what have you to tell me?" "You saw Luigi in Naples, I believe?" "He met me there, with Conrad," the girl answered. "I could not help thinking that it was an imprudence on his part." "Luigi is always imprudent; and yet I cannot help feeling that he is safer in his folly than we are in our care. He told you of the scheme the Council had originated?" The girl nodded an assent. "He gave me to understand, however, that you would furnish me with full particulars," she said. "I am prepared to do so now," her companion replied. As he said this, he led her from the main street into a dark alley, where, having convinced himself that they had not been followed, he set to work and told his tale. So anxious was he that there should be no mistake about the matter, that when he had finished it he began it again, only to repeat it a third time. The woman listened with rapt attention.
