Season 3

A young Don Juan is found murdered in front of his apartment building and an elderly couple are reported missing after an excursion to the ancient site of Tindari. Inspector Montalbano tries to solve these two seemingly unrelated cases amid the daily complications of life at Vigata police station. But when he discovers that the couple and the murdered young man lived in the same building, his investigation stumbles onto Sicily's brutal 'New Mafia' and leads him down a path more twisted and far-reaching than any he has ever been down before.

Goldsmith Alberto Larussa appears to have committed suicide by turning his wheelchair into an electric chair. But Inspector Montalbano discovers that the dead man's will, which leaves everything to his brother Giacomo, was forged. Giacomo is arrested, but he maintains that he did not kill Alberto. Meanwhile, Deputy Inspector Mimi Augello is working on the case of a mysteriously-murdered electrician.
