"Well, then, the Frenchman took off his mask; Teresa, with the chief's consent, did the same. The Frenchman asked for a rendezvous; Teresa gave him one -- only, instead of Teresa, it was Beppo who was on the steps of the church of San Giacomo."

"Was a lad of fifteen," replied Peppino. "But it was no disgrace to your friend to have been deceived; Beppo has taken in plenty of others."http://dumas.thefreelibrary.com/Count-of-Monte-Cristo/1-37
