Who is Pasquale in the short-story, Il Conde?

Pasquale, the peddler, provides the information that the young robber is a member of a "Camorra." Although a poor man living by his wits, Pasquale is shown to be more knowledgeable about the urban life of Naples than the wealthy Count: his existence on the fringe of respectable society has taught him to be less trusting and vulnerable.
