Two girls grow up in a poor Naples neighbourhood in the 1950s, one pushed on by school, the other by sheer brilliance. Elena Ferrante's four Neapolitan Novels follow their friendship from a doll thrown down a cellar chute to a package in the mail in 2010.
The route runs from the district of the first book through Ischia, Pisa, San Giovanni a Teduccio and Florence to Turin. The books never name the streets, so most pins mark areas, not buildings.
Tom Ripley is paid $1,000 to travel to Italy and persuade Dickie Greenleaf to return to the United States. Claiming to be a former Princeton classmate, he slides into Dickie's life, and a friendship at the seaside turns into a trail of lies and killings.
The route follows the film's order through Ischia and Procida, Anzio, Naples, Rome and Venice. Many places play other places: Ischia and Procida stand in for the fictional village of Mongibello, Anzio plays San Remo, and the "Roman" opera house is in Naples.
