The GHI team heads to Italy for a pair of palace investigations. The first takes them to Fosdinovo, Italy, location of Malaspina Castle. Built in the 11th Century, the structure has been owned by one family for hundreds of years. Pietro, the latest in the line of owners, shows the team around to sites in which visitors have seen shadows, heard screams, and witnessed poltergeist activity like drawers opening and closing on their own.

That settled, the team moves on to its second case, Palazzo Ducale in Genoa, Italy. Once a seat of government, the palace has a long and bloody history of political intrigue. In addition to the murder of various government officials, some notable names were imprisoned there. Among them was violinist Nicolo Paganini, whose music is still heard reverberating in the halls. Also heard are sounds of wailing and crying, and one artisan working on restoring a fresco reported hearing a voice telling her, "Good job."
