Season 19 of this docuseries concludes with "The Caravaggio Heist," a new episode that revisits the 1984 theft of a Maltese national treasure from the Cathedral of St. John in Valletta. The purloined painting was an acknowledged masterpiece by Caravaggio, and when a two-year investigation across Europe yielded no results, Malta's director of museums, Father Marius Zerafa, refused to give up. Eventually, he established communication with the thieves and set off to recover the painting, putting his life on the line despite sufficient funds to pay its ransom.
