 Bellodi is unable to determine whether Colasberna was murdered because he stumbled onto a corruption racket or because he was a lover of Rosa, and was shot by her husband, who disappeared after the murder.Another possibility is that Nicolosi saw the murderer and was also murdered, or went into hiding fearing for his life.Bellodi is thwarted by an honour system, where witnesses lie and withhold information out of allegiance to the local Mafia don, Mariano Arena (Cobb).
