Among his colleagues at the police station are his Deputy, Inspector Domenico 'Mimì' Augello, Detective Giuseppe Fazio, officer Galluzzo and the awkward policeman Agatino Catarella. Montalbano must investigate various criminal acts in his area which, thanks to his intelligence and the help of numerous assistants, even outside the police, he always manages to solve by reconstructing the exact events.
Inspector Salvo Montalbano, the police chief (commissario) of Vigàta, a fictional town in the fictional province of Montelusa in Sicily, is a gruff character who is responsible and serious at work, but often also open and friendly with people he knows he can trust.
