“I am now quite at your service, gentlemen,” said he. “The carriage is going one way to the Piazza del Popolo, and we will go another; and, if you please, by the Corso. Take some more of these cigars, M. de Morcerf.”

“With all my heart,” returned Albert; “Italian cigars are horrible. When you come to Paris, I will return all this.”

“I will not refuse; I intend going there soon, and since you allow me, I will pay you a visit. Come, we have not any time to lose, it is half-past twelve⁠—let us set off.”

All three descended; the coachman received his master’s orders, and drove down the Via del Babuino. While the three gentlemen walked along the Piazza di Spagna and the Via Frattina, which led directly between the Fiano and Rospoli palaces, Franz’s attention was directed towards the windows of that last palace, for he had not forgotten the signal agreed upon between the man in the mantle and the Transtevere peasant.
