They've made a fresh start at the Pizzofalcone precinct of Naples. They fired every member of the investigative branch after they were found guilty of corruption. Now, there's a group of detectives, a new commissario, and a new superintendent. The new cops immediately find themselves investigating a high-profile murder that has the whole town on edge. Heading the investigation is Inspector Lojacono, known as "the Chinaman," a cop with a checkered past who is currently riding a reputation as a crack investigator after having captured a serial killer known as "The Crocodile." Lojacono's partner is Aragona, who wants to be known as "Serpico," but the name doesn't stick. Luigi Palma, a.k.a. "Gigi," is the Commissario, Francesco Romano, known as "Hulk," is the slightly self-deluded lieutenant. Lojacono, Aragona, Palma, and Romano are joined by a cast of cops portrayed by bestselling author Maurizio de Giovanni with depth and intimate knowledge of the close-knit world of police investigators.
